Preoperative anti-Müllerian Hormone Levels Research Articles

Initial Preoperative Hemoglobin Level Affects the Rate of Decline in Anti-Müllerian Hormone Levels after Laparoscopic Ovarian Cystectomy in Women with Ovarian Endometriosis.

To determine the factors affecting the decline in ovarian reserve following laparoscopic ovarian cystectomy (LOC) in women with ovarian endometriosis. This retrospective study included 22 women, aged 25-45 years, with regular menstrual cycles who underwent unilateral LOC and were diagnosed with ovarian endometriosis at a university hospital. Blood samples were collected preoperatively and on the third postoperative day to determine the serum anti-Müllerian hormone (AMH) levels for assessment of the decline in ovarian reserve during the early postoperative period. The preoperative hemoglobin level, white blood cell count, and AMH level were associated with changes in the AMH level after unilateral LOC. Among these parameters, only the preoperative hemoglobin level was correlated with the rate of decline in postoperative AMH levels. The preoperative serum AMH level was correlated with the amount of postoperative AMH change but not with its rate of decline. Preoperative hemoglobin levels may be associated with the rate of decline in AMH levels in the early postoperative period after unilateral LOC.

Identification of lesional attributes of dysmenorrhea severity and the serum antimüllerian hormone levels in women with ovarian endometriomas

To investigate whether lesional immunostaining of putative biomarkers of recurrence and the extent of lesional and cortical fibroses are correlated with the severity of dysmenorrhea and serum antimüllerian hormone (AMH) levels in women with ovarian endometriomas (OEs). Retrospective cohort study. Academic hospital. A total of 313 women with histologically confirmed OEs were recruited. Their demographic and clinical information and data on their preoperative AMH levels were collected. Additionally, samples of their lesional tissues and ovarian cortex tissues adjacent to the OE lesions were procured for histologic and immunohistochemistry analyses. None. All OE tissue samples were stained for phosphorylated nuclear factor κB p65 subunit, progesterone receptor isoform B, Slit2, and α-smooth muscle actin. In addition, the extent of lesional and cortical fibroses was quantitated by Masson trichrome staining. We evaluated the relationship between the lesion size; laterality; extent of lesional and cortical fibroses, along with the putative markers of recurrence; and severity of dysmenorrhea and preoperative serum AMH levels in patients with OE. We found that the extent of lesional fibrosis was positively correlated with the severity of dysmenorrhea but had no impact on the AMH levels. On the other hand, the extent of cortical fibrosis, along with age, was negatively correlated with the AMH levels. The correlation between lesional fibrosis and the severity of dysmenorrhea and between cortical fibrosis and the AMH levels would call an early intervention once OE is diagnosed or suspected to prevent further pain and diminished ovarian reserve.

P–328 Dienogest significantly decreases the size of the cyst and alters Anti-Müllerian Hormone concentration in patients with endometrioma

Abstract Study question Does utilization of dienogest make any impact on the size of cyst and Anti-Müllerian Hormone (AMH) concentration in patients with endometrioma throughout 12-months? Summary answer Although dienogest makes a gradual reduction in the size of endometrioma cyst throughout 12-months, a significant drop in AMH serum concentration was also noticed. What is known already According to recent studies, pre-operative serum AMH levels might be illusively increased with parallel to the size of endometrioma which will be a misleading factor while deciding to operate the patient via cystectomy. Although dienogest is one of the medical options that might be commenced in patients with endometrioma cyst, there is limited data about its effect on the size of the endometrioma and hence serum AMH concentration throughout 12 months of follow up. Study design, size, duration The current observational cohort study was conducted among patients with endometrioma those treated with dienogest from January 2017 to January 2020. The primary outcome was alteration in diameter of endometrioma cyst at 6th and 12th months of treatment. Secondary outcome was alteration in serum AMH concentration in the same period. Of 104 patients treated with dienogest, 44 patients were excluded due to being treated with any type of surgical intervention during follow up period. Participants/materials, setting, methods A total of 60 patients were recruited for the final analysis. Of them, primary symptom was dysmenorrhea, chronic pelvic pain and menstrual irregularity in 16 (26.7%), 25 (41.7%) and 8 (13.3%) patients, respectively. Eighteen patients (30%) were asymptomatic. As 21 patients had bi-lateral endometrioma, size of the leading cyst was considered to be analyzed for the primary outcome measure. Paired-t test was used for comparison of numerical values and p ≤ 0.05 was taken as statistical significance. Main results and the role of chance The mean age was 31.5±8.0 years. In the time point when dienogest was started, the mean size of the endometrioma was 46.3±17.4 mm. The mean serum AMH concentration was 3.6±2.4 ng/ml. After 6 months of treatment, the mean size of the endometrioma decreased to 38.6±14.0 mm which corresponds to a mean difference of 7.8 mm (95% CI: 3.0 to 12.6; p: 0.003). The respective figure for AMH was 3.3±2.7 ng/ml which corresponds to a mean difference of 0.3 ng/ml (95% CI: –0.2 to 0.8; p: 0.23) at 6 months. After 12 months of treatment, the mean size of the endometrioma was 37.5±15.7 mm which corresponds to a mean difference of 8.9 mm (95% CI: 2.9 to 14.9; p: 0.005) at the end of 12 months. The respective figure for AMH was 2.7±1.9 ng/ml which corresponds to a mean difference of 0.9 ng/ml (95% CI: 0.1 to 1.7; p: 0.045) at the end of 12 months. The mean diameter of endometrioma and AMH concentration did not differ throughout the time period between 6th and 12th months of the treatment. Limitations, reasons for caution Although herein we present the largest data that depicts the alteration of endometrioma cyst and AMH concentration with the application of dienogest, the lack of control group is a limitation that avoids to perform any comparison. Wider implications of the findings: A shrinkage after commencement of treatment suggest that dienogest might present improvement in patients with endometrioma with respect to radiological findings, but further studies are required whether a decline in AMH concentration after 12 months refers to a genuine decrease in ovarian reserve or resolution of misleading high pre-treatment levels.

Decrease in serum anti-Müllerian hormone level per puncture with laparoscopic ovarian drilling using ultrasonically activated device.

PurposeTo determine the contributing factor in infertility treatment with laparoscopic ovarian drilling (LOD) to the decrease in serum anti‐Müllerian hormone (AMH) levels in patients with polycystic ovarian syndrome using an ultrasonically activated device.MethodsA retrospective analysis was performed in 60 patients (aged 23–36 years) who received 25–120 punctures in each ovary with LOD treatment from January 2014 to December 2018.ResultsThe mean decrease in serum AMH level per puncture with LOD was 0.07 ± 0.04 ng/ml in all 60 patients and 0.08 ± 0.04 ng/ml in patients with ≥10 ng/ml preoperative serum AMH level, which was significantly higher than in those with <10 ng/ml (0.05 ± 0.02 ng/ml). The mean decrease in serum AMH level per puncture in patients with body mass index (BMI) < 18.5 kg/m2 (0.10 ± 0.03 ng/ml) was significantly higher than in those with BMI 18.5–25 kg/m2 (0.07 ± 0.04 ng/ml) and >25 kg/m2 (0.06 ± 0.02 ng/ml).ConclusionsThe mean decrease in serum AMH levels per puncture with LOD using an ultrasonically activated device depends on the preoperative serum AMH level and BMI of patients.

Changes in anti-müllerian hormone after ultrasound guided aspiration and ethanol sclerotic therapy of ovarian cyst

ObjectiveTo evaluate the effect of transvaginal ultrasound-guided aspiration and ethanol sclerotherapy on anti-müllerian hormone (AMH) in patients with ovarian endometriomas. Setting: Teaching hospital affiliated with Chang Gung University, Taipei. Material and methodsWe retrospectively reviewed 124 patients, with ovarian endometriomas who underwent transvaginal aspiration and sclerotherapy of endometrioma(s) at a tertiary medical center, Chang Gung Memorial Hospital, Taipei, Taiwan. Preoperative evaluation included AMH, midcycle serum CA-125 level, and ultrasonography to exclude possibility of malignancies. Patients underwent ultrasonographic guided transvaginal aspiration and sclerotherapy with 95% ethanol irrigation of the cystic cavity. Patients were grouped into group 1, n = 44, retention of ethanol, and group 2, n = 80, no retention. Serum AMH level was checked at 6 months after aspiration. Those who were infertile prior to therapy were followed up for subsequent pregnancies (either by assisted reproductive technologies, or by natural conception). ResultsThe mean pre-operative AMH levels for the group without retention of ethanol and with ethanol retention were 3.80 and 3.06 respectively (p > 0.05). The change in AMH at 6-month follow up for retained group patients was significantly more than for non-retained group patients, with mean decrease of 0.72 (23.6%) and 0.10 (2.7%) respectively (p < 0.05). 54.5% (retained) and 47.2% (non-retained) of patients failed to achieve pregnancy during the observation period. ConclusionsTransvaginal aspiration of endometriomas followed by sclerotherapy with ethanol can be effective in preserving ovarian reserve, provided that no ethanol is left in situ.

Impact of Surgical Management of Endometrioma on AMH Levels and Pregnancy Rates: A Review of Recent Literature.

Ovarian endometrioma are found in up to 40% of women with endometriosis and 50% of infertile women. The best surgical approach for endometrioma and its impact on pregnancy rates is still controversial. Therefore, we conducted a literature review on surgical management of ovarian endometrioma and its impact on pregnancy rates and ovarian reserve, assessed by anti-Müllerian hormone (AMH) serum levels. Ovarian cystectomy is the preferred technique, as it is associated with lower recurrence and higher spontaneous pregnancy rate. However, ablative approaches and combined techniques are becoming more popular as ovarian reserve is less affected and there are slightly higher pregnancy rates. Preoperative AMH level might be useful to predict the occurrence of pregnancy. In conclusion, AMH should be included in the preoperative evaluation of reproductive aged women with endometriosis. The surgical options for ovarian endometrioma should be individualized. The endometrioma ablation procedure seems to be the most promising treatment.

Ovarian Reserve Reduction With Surgery Is Not Correlated With the Amount of Ovarian Tissue Inadvertently Excised at Laparoscopic Surgery for Endometriomas.

The aim of the present study was to evaluate the effect of laparoscopic cystectomy on ovarian reserve by means of anti-Müllerian hormone (AMH) serial measurements and to compare AMH values with the number of inadvertently removed follicles in histological specimens. Fifty-two women were enrolled: 34 patients with endometriomas (group 1) and 18 patients with other benign ovarian cysts (group 2). All patients underwent laparoscopic cystectomy performed by a single experienced surgeon. The AMH was measured before, and 1, 3, and 6 months after cystectomy in group 1, and before and 6 months after surgery in group 2. Preoperative AMH levels (mean [standard deviation, SD]) in group 1 (3.39 [2.43] ng/mL) were not significantly different from group 2 (3.74 [2.57] ng/mL; P = .68). In group 1, a significant decrease in AMH levels of 43.4% was observed at 1 month (1.93 [1.36]; P = .003), and of 63.1% at 3 months (1.25 [1.00]; P = .007) postoperatively. The AMH increased not significantly between the third and sixth months in group 1 (+9.4%). Six months after surgery, AMH was reduced by 59.3% compared to baseline values in group 1 (P = .012), and by 29.5% in group 2 (P = .200). A significant difference in the AMH decrease was present between bilateral and monolateral endometriomas (P = .006). There was no correlation between the reduction rate of AMH and the number of follicles inadvertently removed in patients with endometriomas (P = .669). In conclusion, AMH decreases significantly after surgical excision of ovarian endometriomas. The postoperative decrease does not appear to correlate with the amount of ovarian tissue inadvertently excised with the endometrioma wall.

Predictive value of the serum anti-Müllerian level for spontaneous pregnancy in women after endometriosis surgery.

ObjectiveThis study was performed to assess the predictive value of the anti-Müllerian hormone (AMH) serum level for spontaneous pregnancy in women after endometriosis surgery.MethodsIn total, 124 patients with suspected ovarian endometrioma planning to undergo laparoscopic ovarian cystectomy were divided into a high AMH group (AMH > 2 ng/mL) and low AMH group (AMH ≤ 2 ng/mL) according to their preoperative AMH levels. The postoperative AMH levels were also measured, and pregnancy outcomes were followed up.ResultsTwenty-one patients were excluded, and 52 pregnancies were registered in the remaining 103 patients diagnosed with endometriosis. The pregnancy rate was significantly greater in the high than low AMH group. Receiver operator characteristics analysis of preoperative AMH, postoperative AMH, and the AMH decline rate showed that preoperative AMH was associated with the greatest area under the curve. Kaplan–Meier curves showed that women in the high AMH group had a significantly higher cumulative pregnancy rate than those in the low AMH group.ConclusionThe preoperative AMH level might be a useful marker to predict the occurrence of natural pregnancy and could be offered as part of the fertility strategy to women who desire pregnancy after endometriosis surgery.

Preoperative serum anti-Müllerian hormone level is a potential predictor of ovarian endometrioma severity and postoperative fertility

ObjectiveTo establish a model for predicting revised American Society of Reproductive Medicine (rASRM) scores before endometrioma surgery based on serum anti-Müllerian hormone (AMH) level and to identify factors that might reliably predict postoperative fertility of women diagnosed with endometrioma. Study designThe study population was composed of 134 women with endometrioma, 58 with benign cyst, and 115 with non-ovarian lesion. Preoperative serum AMH level and clinical parameters were compared among three groups. Univariate correlation analyses and multivariate linear regression modeling with a stepwise method were performed for constructing an rASRM scores prediction model. Cox regression analysis was then used to identify predictive variables of spontaneous pregnancy following surgical treatment of endometrioma. ResultsPreoperative AMH level were significantly lower in the endometrioma group than in the other two groups (p < 0.001). Multivariate linear regression analysis revealed that age (β=-0.324, p < 0.001), rASRM scores (β=-0.298, p < 0.001) and serum CA125 level (β=-0.176, p = 0.026) independently and negatively correlated with serum AMH level. Cox regression analysis of women with endometrioma who underwent surgical resection indicated that older age (per five-year increase, HR: 0.517; 95% CI, 0.299–0.896) and higher serum AMH level (cut-off value: >3.68 ng/ml, HR: 2.383; 95% CI, 1.093–5.197) were independent predictors for postoperative fertility. ConclusionPatients with advanced staged endometriosis tended to have a lower serum AMH level while postoperative infertility was more likely to occur in older patients with a lower level of serum AMH. Thus, timely detection of AMH levels to assess the severity of ovarian endometriosis and possibility for postoperative pregnancy success is necessary to ensure that optimal medical treatment can be provided.

Serum anti-Müllerian hormone concentration before and after salpingectomy for ectopic pregnancy.

Does salpingectomy for ectopic pregnancy affect the ovarian reserve measured by changes in pre- and post-operative levels of anti-Müllerian hormone (AMH)? This is a prospective observational multicentre study of 64 women treated with salpingectomy for an ectopic pregnancy. AMH was measured in serum samples collected at admission before salpingectomy and at follow-up (median time to follow-up [interquartile range] was 3 [3-4] months). Changes in serum AMH levels were investigated using Wilcoxon signed-rank test and the relationship between changes in AMH and age, time to follow-up, and pre-operative serum AMH level was investigated using linear regression analysis. The biological variation of AMH was also calculated. Serum AMH levels did not differ significantly before and after salpingectomy (median ∆AMH [follow-up value minus admission value] 0.40 pmol/l, interquartile range -2.0 to 4.0 pmol/l). ΔAMH was independent of age, time to follow-up and pre-operative serum AMH level. The intra-individual biological variation for AMH ranged from 12.1% to 26.3%, depending on time between the two samples. This is the first paired study to investigate serum AMH values before and after salpingectomy in an unselected population of women presenting with an ectopic pregnancy, including both patients who conceived naturally and following fertility treatment. It was found that salpingectomy for ectopic pregnancy had no short-term effect on serum AMH levels, and changes in AMH levels were independent of age, time to follow-up, and pre-operative serum AMH level. Furthermore, the study demonstrated a 6-month biological variation of AMH of less than 30%.

Usefulness of hemostatic sealants for minimizing ovarian damage during laparoscopic cystectomy for endometriosis.

We aimed to evaluate the impact of topical hemostatic sealants and bipolar coagulation during laparoscopic ovarian endometriotic cyst resection on ovarian reserve by comparing the rates of decrease in anti-Müllerian hormone (AMH). A randomized prospective data collection was made on women aged 19-45 years who planned to have laparoscopic ovarian cystectomy at one of two institutions (n = 80), Kangbuk Samsung Hospital, Seoul, Korea or National Health Insurance Service Ilsan Hospital, Goyang, Korea, from January 2014 to April 2016. Patients were randomly divided into two groups treated with either a topical hemostatic sealant or bipolar coagulation for hemostasis. The hemostatic group was randomized to the FloSeal or TachoSil subgroups. Preoperative and 3-month postoperative AMH levels were checked and the rates of decrease of AMH were compared. All patients enrolled were treated with dienogest (Visanne) for 6-12 months. None were lost to follow-up at postoperative 3 months, but about one-third of the patients had been lost to follow-up by 6-12 months. AMH was significantly decreased in both groups 3 months postoperatively; however, the rate of decrease in the bipolar coagulation group was greater than that in the hemostatic sealant group, 41.9% (interquartile range [IQR], 22.29-65.24) versus 18.1% (IQR, 10.94-29.90), P = 0.007. Between the two hemostatic subgroups, there was no significant difference in AMH decrease rate, 14.95% (IQR, 11.34-21.21) versus 18.1% (IQR 9.76-40.70), P = 0.204. Hemostatic sealants may be an alternative to bipolar coagulation for preservation of ovarian reserve after laparoscopic ovarian cystectomy for endometriosis.

Impact of pre and post laparoscopic ovarian treatment on ovarian reserve with infertile women : prospective study

We used laparoscopy to treat endometriosis and other causes of infertility in women to help improve chances for pregnancy. In 2013, we conducted a retrospective analysis using anti- müllerian hormone (AMH) serum to investigate the effects of laparoscopic treatment on ovaries. The aim of this new study was to determine the impact of laparoscopic ovarian treatment on ovarian reserve as measured by AMH in a prospective analysis. Prospective study This study involved 357 infertile women who received laparoscopic examination and treatment of ovaries prior to in-vitro fertilization (IVF) treatment at St. Luke Clinic, between March 2013 and October 2016. The patients were divided into four groups according to the kind of laparoscopy treatment conducted: 1) Ovarian drilling for polycystic ovary syndrome (LOD) (n=48); 2) Ethanol Sclerotherapy for chocolate cyst of the ovary (ES) (n=32); 3) Removal of ovarian endometriosis with electrocautery (EC) (n=213); and 4) No treatment to ovaries(some had laparoscopic procedures on areas other than ovaries) (Control) (n=64). From the previous study, we found that AMH levels were higher during the follicle phase than the luteal phase. Therefore, we measured AMH levels immediately prior to laparoscopic procedures, and during the follicle phase 2 days, 1 month, 3months, 6months post procedure. The AMH levels in the serums among the four groups were compared pre and post laparoscopy. The decreased ratio of AMH levels was evaluated [pre-operative AMH level]-[post-operative AMH level] / pre-operative AMH level, and compared among the four groups. In all four groups, the mean AMH levels after laparoscopy were significantly lower than before the laparoscopy (the mean AMH level prior to laparoscopy, and 2 days, 1, 3, and 6 months post laparoscopy, AMH levels: LOD: pre 9.4ng/ml and 7.1ng/ml, 5.6ng/ml, 5.4ng/ml, 6.1ng/ml; ES: pre 4.2ng/ml and 3.6ng/ml, 2.9ng/ml, 2.8ng/ml, 2.2ng/ml; EC: pre 3.4ng/ml and 2.9ng/ml, 2.5ng/ml, 2.8ng/ml, 2.7ng/ml; Control: pre 4.1ng/ml and 3.8ng/ml, 3.1ng/ml, 3.3ng/ml, 2.7ng/ml). The mean decrease ratio of the AMH levels 2 days post laparoscopy were significantly different between LOD and Control, and EC and Control (LOD: 23.5%, EC: 15.4%, Control 5%; there was no significant difference between ES:16.1% and Control). There was no significant difference between the mean decrease ratio of AMH levels at 1, 3, and 6 months post laparoscopy (1month; LOD: 38%, ES: 21.1%, EC: 13.5%, Control: 8%, 3month; LOD:34.6%, ES: 36.3%, EC: 8.9%, Control: 7.5%, 6month; LOD: 32.6%, ES:34.8%, EC: 6.2%, Control: 10.4%). This study suggests that ovarian reserve may be reduced after laparoscopy regardless of whether the laparoscopic treatment is to the ovaries or only to the uterus. LOD, ES, EC appears to have little influence on ovarian reserve.

The impact of laparoscopic ovarian drilling on AMH and ovarian reserve: a meta-analysis.

Laparoscopic ovarian drilling (LOD) has been widely used as an effective treatment of anovulatory women with polycystic ovarian syndrome (PCOS). However, there has been a growing concern over a possible damaging effect of this procedure on ovarian reserve. The objective of this study was to investigate the hypothesis that LOD compromises ovarian reserve as measured by post-operative changes in circulating anti-Müllerian hormone (AMH). This meta-analysis included all cohort studies as well as randomised controlled trials (RCTs) investigating serum AMH concentrations and other ovarian reserve markers in women with PCOS undergoing LOD. Various databases were searched including MEDLINE, EMBASE, Dynamed Plus, ScienceDirect, TRIP database, ClinicalTrials.gov and Cochrane Library from January 2000 to December 2016. Sixty studies were identified, of which seven were deemed eligible for this review. AMH data were extracted from each study and entered into the RevMan software to calculate the weighted mean difference (WMD) between pre- and post-operative values. Pooled analysis of all studies (n = 442) revealed a statistically significant decline in serum AMH concentration after LOD (WMD -2.13 ng/mL; 95% confidence interval (CI) -2.97 to -1.30). Subgroup analysis based on duration of follow-up, AMH kit, laterality of surgery and amount of energy applied during LOD consistently showed a statistically significant fall in serum AMH concentration. In conclusion, although LOD seems to markedly reduce circulating AMH, it remains uncertain whether this reflects a real damage to ovarian reserve or normalisation of the high pre-operative serum AMH levels. Further long-term studies on ovarian reserve after LOD are required to address this uncertainty.

Which Should Be the Preferred Technique During Laparoscopic Ovarian Cystectomy: Hemostatic Sutures or Bipolar Electrocoagulation? A Randomized Controlled Prospective Study of Long-Term Ovarian Reserve

The aim of the present study was to determine the long-term effects of different laparoscopic hemostatic techniques on ovarian reserve after ovarian cystectomy. Ninety patients with unilateral ovarian cysts were recruited and randomly distributed into 2 groups. Laparoscopic stripping cystectomy was performed in all patients. Afterward, cystectomy hemostasis was achieved via hemostatic suture or bipolar electrocoagulation. Serum levels of anti-Müllerian hormone (AMH) were determined preoperatively and postoperatively at 1, 3, and 12 months, and patients were evaluated for residual ovarian volume, antral follicle count, and pregnancy. The statistical difference was determined between the 2 groups in terms of AMH levels at 3 months (hemostatic suture group = 3.17 ± 3.40 vs bipolar electrocoagulation group = 2.38 ± 2.57, P = .006) and 12 months (hemostatic suture group = 3.71 ± 3.09 vs bipolar electrocoagulation group = 2.78 ± 2.85, P = .005). In addition, in the hemostatic suture group, there was no statistically significant difference between preoperative and postoperative AMH levels ( P = .165) and between the postoperative antral follicle count ( P = .779) and the residual ovarian volume ( P = .248), whereas in the bipolar electrocoagulation group, postoperative AMH levels were lower than preoperative levels ( P = .028) and postoperative residual ovarian volumes at 3 and 12 months were lower than those at 1 month ( P = .001). Nonetheless, pregnancy rates were not significantly different ( P = .546). Bipolar electrocoagulation is more destructive compared with hemostatic suture. However, the ovarian reserve does not decrease further during the follow-up period.

Does preoperative antimüllerian hormone level influence postoperative pregnancy rate in women undergoing surgery for severe endometriosis?

To compare postoperative pregnancy rates as they relate to presurgery antimüllerian hormone (AMH) level in patients with stage 3 and 4 endometriosis. Retrospective comparative study using data prospectively recorded in the North-West Inter-Regional Female Cohort for Patients with Endometriosis (CIRENDO) database. University tertiary referral center. One hundred eighty patients with stage 3 and 4 endometriosis and pregnancy intention, managed from June 2010 to March 2015, were divided into two groups according to their preoperative AMH levels: group A (AMH ≥2ng/mL) and group B (AMH <2ng/mL). Surgical procedure involved ovarian endometrioma ablation by plasma energy along with resection of various localizations of the disease. Postoperative conception was either spontaneous or used assisted reproductive technology, depending on patient characteristics. Patient characteristics, preoperative symptoms, infertility history, intraoperative findings, and probability of pregnancy were recorded and compared between the two groups. Among 180 women enrolled in the study, 134 (74.4%) were assigned to group A and 46 (25.6%) to group B. The women's ages were, respectively, 30 ± 3.8 and 32 ± 4.6years. Pregnancy was achieved by 134 (74.4%) patients, and conception was spontaneous in 74 of them (55.2%). Pregnancy rates in groups A and B were, respectively, 74.6% (100 women) and 73.9% (34 women), while spontaneous conception represented 54% (54 women) and 58.8% (20 women). The probability of pregnancy at 12, 24, and 36months after surgery in groups A and B was comparable, respectively, 65% (95% confidence interval [CI], 55%-75%), 77% (95% CI, 86%-68%), and 83% (95% CI, 90%-75%) versus 50% (95% CI, 69%-34%), 77% (95% CI, 90%-61%), and 83% (95% CI, 94%-68%). Supplementary analysis in women with normal (≥2ng/mL), low (1-1.99ng/mL), and very low (<1ng/mL) AMH level showed an inverse relationship between AMH level, age, and antecedents of miscarriage; however, postoperative pregnancy rates were comparable among the three groups at 12 and 24months, respectively, 59.5% (95% CI, 49.3%-70%) and 77.4% (95% CI, 68%-85.4%); 57.1% (95% CI, 34%-83%) and 78.6% (95% CI, 55.2%-94.8%); and 46.7% (95% CI, 25.6%-73.7%) and 73.3% (95% CI, 50.4%-91.7%). The probability of postoperative pregnancy was comparable between women with low and normal AMH level who were managed for stage 3 and 4 endometriosis and who were a mean age of 30years. However, the small sample size might have been unable to detect differences in pregnancy and live-birth rates between the two groups. As the majority of pregnancies were spontaneous, our results suggest that surgical management may be offered to young patients with severe endometriosis and reduced ovarian reserve with good fertility outcomes.

The impact of laparoscopic cystectomy on ovarian reserve in patients with unilateral and bilateral endometrioma.

To evaluate the effects of laparoscopic cystectomy on serum anti-Müllerian hormone (AMH) level as a marker of ovarian reserve in patients with endometrioma. A prospective observational study enrolled patients aged younger than 40years who were referred to a tertiary center in Tehran, Iran, between January 1, 2013 and December 31, 2014 to undergo laparoscopic cystectomy for ovarian endometriomas at least 30mm in diameter, or regardless of size for patients with infertility, dysmenorrhea, dyspareunia, or dyschezia. Baseline and 6-month post-operative AMH levels were compared. Data from 70 patients were included in the analyses. Among patients with unilateral endometriomas, lower pre-operative AMH levels were observed in patients with endometriomas at least 50 mm in diameter (P=0.027), whereas cyst size was not associated with differences in pre-operative AMH level in patients with bilateral endometriomas (P=0.227). Across the entire study population, post-operative AMH levels were lower than the baseline (P=0.008). Greater post-operative decreases in AMH were associated with bilateral cysts compared with unilateral cysts (P=0.046), cysts being at least 50 mm in diameter among patients with unilateral cysts (P=0.028), and both cysts being at least 50 mm in diameter among patients with bilateral cysts (P=0.025). Laparoscopic cystectomy was associated with post-operative decreases in serum AMH, particularly with bilateral involvement and endometriomas at least 50mm in diameter.

Comparison of early postoperative decline of serum antiMüllerian hormone levels after unilateral laparoscopic ovarian cystectomy between patients categorized according to histologic diagnosis

ObjectiveTo evaluate the change of ovarian reserve after unilateral laparoscopic ovarian cystectomy (LOC) in the early postoperative period between patients divided according to histologic diagnosis of cyst type. Materials and MethodsSixty-five patients who were undergoing unilateral LOC for benign ovarian disease were included in this study. All participants were divided into three groups according to histologic diagnosis: endometrioma (n=26), mature teratoma (n=24), and other benign cyst (n=15). Serum samples were collected preoperatively and 3-days postoperatively and assayed for antiMüllerian hormone (AMH) levels, and the changes between the two samples were analyzed. ResultsPreoperative AMH levels were not significantly different between the three groups. On postoperative Day 3 AMH levels of all three groups were significantly reduced compared with preoperative AMH levels. The rates of decline of AMH levels after LOC in patients with endometrioma (26.37±20.70%) and in those with teratoma (28.25±22.16%) were both significantly higher than those with other benign cyst (12.03±18.56%). No statistically significant differences were found in the rate of decline of AMH levels between patients with endometrioma and teratoma. Decline of AMH after LOC was not significantly correlated with age, body mass index, the size of cyst, or preoperative AMH levels. ConclusionOur results suggest that ovarian reserve is reduced after unilateral LOC in the early postoperative period, and that the postoperative decline of AMH levels after LOC is similar between patients with endometrioma and those with mature teratoma.

The impact of salpingectomy and single-dose systemic methotrexate treatments on ovarian reserve in ectopic pregnancy

ObjectiveTo investigate the effects of salpingectomy and methotrexate treatments on ovarian reserve in ectopic pregnancy. Study designIn this prospective study, a total of 131 patients with ectopic pregnancy were divided into 3 groups of methotrexate (MTX) only (Group-1, n: 55), salpingectomy only (Group-2, n: 61), and salpingectomy following MTX (Group-3, n: 15). Pretreatment and post-treatment anti-Müllerian hormone (AMH) levels were evaluated. ResultsSignificant differences in AMH levels were detected between group 1 and group 2 (2.52±1.28 vs. 1.96±1.66, p=0.043), and group 1 and group 3 (2.52±1.28 vs. 1.77±0.76, p=0.035) at one month postoperative. However, these differences disappeared at the 3rd postoperative month. When AMH levels were compared within the same group, postoperative one month AMH levels were significantly lower than the preoperative AMH levels only in group 3 (p=0.03). However, this difference also disappeared at the 3rd postoperative month. ConclusionSystemic single-dose methotrexate treatment, unilateral salpingectomy, and salpingectomy following methotrexate administration in ectopic pregnancy were reassuring based on pretreatment and post-treatment AMH levels. Current medical and surgical treatment approaches do not have an obvious negative effect on ovarian reserve.

Impact of opportunistic salpingectomy on anti-Müllerian hormone in patients undergoing laparoscopic hysterectomy: a multicentre randomised controlled trial.

The aim of the study was to investigate whether opportunistic salpingectomy has any deleterious effects on ovarian reserve and increases surgical risk in patients undergoing laparoscopic hysterectomy. A multicentre, randomised controlled trial. Three university hospitals in Korea. Sixty-eight patients undergoing laparoscopic hysterectomy for the treatment of symptomatic benign uterine diseases. Patients were randomised to undergo either opportunistic salpingectomy (n=34) or no salpingectomy (n=34) during laparoscopic hysterectomy. The primary and secondary outcome measures were the change of ovarian reserve, determined by the rate of decline in anti-Müllerian hormone (AMH) level from before surgery to 3months post-surgery and surgical outcomes, respectively. Baseline demographic and clinical characteristics were similar between the two groups. There was also no difference in operative outcomes such as operative time, operative bleeding, or complications between the two groups. In both groups, postoperative AMH levels were significantly lower than preoperative AMH levels (both, P<0.01). The decline rate in AMH was 12.5% (interquartile range 0.8-60.9%) in the opportunistic salpingectomy group and 10.8% (interquartile range 6.9-27.4%) in the no salpingectomy group, with no significant difference between both groups (P=0.898). Opportunistic salpingectomy at the time of laparoscopic hysterectomy did not have any negative effects on ovarian reserve or increased surgical risk. Opportunistic salpingectomy did not have any negative effects on ovarian reserve or increased surgical risk.

The Impact of Gradually Increasing Energy Dose on AMH Levels in Ovarian Drilling

Background: To document alterations in Anti-Müllerian hormone (AMH) levels with different energy doses by monopolar cautery in ovarian drilling (OD) in rats. Methods: Forty Wistar rats were randomly divided into 4 groups that each contained 10 animals. Group A was the Sham group. Groups B, C and D were intervention groups to which OD was applied by monopolar cautery, with 20, 60 and 120 J/ovary, respectively. The total amount of energy was calculated using the following formula: energy (J) = power (W) × duration (s) × number of punctures. Results: The pre- and postoperative AMH levels for Groups A, B and C were not statistically and significantly different according to the Bonferroni correction (p > 0.0125). However, the postoperative AMH levels were significantly lower than the preoperative AMH levels in Group D (1.25 ng/ml (1.07-2.05) vs. 0.40 ng/ml (0.30-0.72); p = 0.012). Conclusions: AMH is a promising marker that can be used for the individualization of the energy dose to increase OD success, but the relationship between the energy and AMH has not been documented yet. This study demonstrates that postoperative changes in AMH levels could be observed only after a certain amount of energy was applied. Further experimental animal models are needed to conclusively address this issue.
