Ultrasound guidance versus the classical method for intrauterine insemination in oral medication-stimulated cycles: A randomized, single-blind, controlled trial

ObjectiveThis study was conducted to compare the pregnancy rates of ultrasound-guided intrauterine insemination (UG-IUI) and classical intrauterine insemination (C-IUI) cycles. Study designA total of 320 infertile women were enrolled and randomized into an UG-IUI group, and a C-IUI group. All participants received an oral medication for ovarian stimulation. With both groups, the IUIs were scheduled and performed by doctors in their residency and fellowship training, under supervision. The duration and difficulty of the procedures were assessed. A pregnancy test was offered 3 weeks later if the participants did not have menstruation. ResultsThe demographic and other baseline characteristics of the groups (baseline hormone levels, cervical length, uterine position, endometrial thickness, and expertise of the providers) were comparable. The pregnancy rates were similar, with 6.9 % and 6.3 % for the UG-IUI and C-IUI groups, respectively. In the UG-IUI group, the pregnancy rate of the multigravida women was three times higher than that of the nulligravida women (15.4 % vs. 5.0 %; p = 0.13). Although the duration of the procedure was shorter for the UG-IUI group (p < 0.05), the level of difficulty was similar for the two groups. ConclusionsFor oral-medication stimulated cycles, UG-IUI did not increase the pregnancy rate more than with C-IUI. However, the pregnancy rate tended to increase with UG-IUI for multigravida women.

The Effects of Ovulation Documentation before Insemination on Intrauterine Insemination Cycle Outcomes: A Retrospective Analysis

Introduction: Ovulation is the key event in Intrauterine Insemination (IUI) cycles. Monitoring ovulation prior to insemination will help to alter insemination time to improve pregnancy rate. Aim: To compare pregnancy rates and live birth rates in presence and absence of ultrasonographic features of ovulation before insemination in IUI cycles. Materials and Methods: This was a retrospective cohort study conducted in a Institute of Medical Sciences and SUM Hospital, Bhubaneswar. Three hundred eighty eight IUI cycles performed in the period of January 2017 to December 2018 were analysed. On the day of IUI prior to insemination, transvaginal ultrasonography was done 36-38 hours after ovulation trigger to document ovulation. Presumptive signs of ovulation were documented in 201 cycles (Group A) and there was no feature suggestive of ovulation in 187 cycles (Group B). In all the cycles, single insemination was performed at 38-40 hours after ovulation trigger. Baseline characteristics were compared. Mann-Whitney U test was used to compare continuous variables. Chi-square test and Fisher’s-exact test were applied to find out the differences in the categorical variables as well as the pregnancy outcomes among the groups. Pregnancy rate and live birth rate were considered as the primary outcomes. Results: Pregnancy rate (17.9% vs 18.2%, p-value=0.945) and live birth rate (17.9% vs 16.0%, p-value=0.625) were similar irrespective of ovulation status documented in ultrasonography performed before insemination. Conclusion: IUI cycle outcomes are independent of the ovulation status documented before insemination.

IUI: Optimizing results, minimizing complications

Intrauterine insemination is a procedure in Assisted Reproductive Techniques (ART) where processed and concentrated motile sperms are placed directly into the uterine cavity. Although NICE [2013] recommends In Vitro Fertilisation over intrauterine insemination after 2 years of unprotected intercourse, Intrauterine Insemination (IUI) appears to be a low cost and effective option before proceeding for In Vitro Fertilisation (IVF). Minimal requirement for IUI is patency of at least one fallopian tube. Adequate number of motile sperms should be present in pre wash specimen of semen. At total sperm count 3–5 million, pregnancy rate is less than 1% per cycle. In unexplained infertility there may be undetected subtle functional defects in follicular development, maturation and ovulation like luteinised unruptured follicle, luteal phase defect. Ovarian stimulation increases the number of dominant follicles and improves their quality resulting in improvement in pregnancy rate. Single IUI has benefits of fewer visits, less cost and stress. Evidence suggests no difference in clinical pregnancy rate between single versus double IUI. WHO recommends ejaculatory abstinence of 2–7 days before semen collection (WHO, 2010), for diagnostics and semen preparation. Shorter time interval between processing and insemination leads to less sperm chromatin decondensation & sperm DNA fragmentation and higher Pregnancy Rate. The luteinizing hormone surge can be detected almost 36 hours before ovulation in serum and 24 hours before ovulation in urine. The optimal time interval between human chorionic gonadotropin (hCG) injection and IUI seems to be between 12 and 36 hours; 24 hours after leutinising hormone (LH) Surge. Nature of sperms is the best guide for choice of technique. “Swim up” techniques are recommended in cases of normozoospermia and “Density Gradient” should be chosen in cases of any pathology of semen. The pregnancy rate per cycle is highest in the first three treatment cycles. Most couples show acceptable cumulative ongoing pregnancy rates after six cycles of IUI with ovulation induction. In vitro fertilization should be considered after 3–6 cycles taking all factors into consideration.

Impact of Intrauterine Administration of Human Chorionic Gonadotropin before Intrauterine Insemination in Infertile Women: A Randomized Controlled Trial.

Background:Implantation is the rate-limiting step in the success of both intrauterine Insemination (IUI) and in vitro fertilization cycles. Numerous interventions that target various local signals have been tried to improve the implantation and clinical pregnancy rate (CPR). The most significant of these signals is human chorionic gonadotropin (hCG) which acts as immunomodulator and improves implantation by decidualization of the endometrial stromal cells, trophoblast invasion, proliferation of uterine natural killer cells, stimulation of endometrial angiogenesis, and maintenance of progesterone secretion by the corpus luteum.Aim:The aim of the study is to evaluate the effect of intrauterine hCG administration before IUI on CPR.Settings and Design:A prospective parallel randomized control study was done from September 2017 to February 2019.Materials and Methods:A total of 200 eligible women planned for IUI were randomly divided just before IUI into 2 groups. A computer-generated randomization list with block size of 10 with 1:1 allocation was used to randomize the patients. Experimental group received 0.5 ml containing 500 IU hCG, on the other hand control group received 0.5 ml of normal saline 2–3 min before IUI in single sitting. The main outcomes were CPR, miscarriage rate, and ongoing pregnancy rate.Statistical Analysis:It was performed using statistical software version SPSS 17.0.Results:Patient's demographic and baseline characteristics were comparable in both the groups. CPR in experimental group was significantly high compared to control group (26% vs. 9%, P = 0.002). Ongoing pregnancy rate was also significantly higher in experimental group (23%) compared to control group (7%) (P = 0.003). No significant difference in miscarriage rate was seen between the two groups. No cases of ectopic pregnancy, ovarian hyperstimulation syndrome, or multiple pregnancy were reported.Conclusion:Intrauterine hCG administration is a simple procedure that can be used to improve pregnancy outcome in IUI cycles.

To Compare the Effect of GnRH Agonist versus Human Chorionic Gonadotropin (HCG) Trigger on Clinical Pregnancy Rate in Intrauterine Insemination Cycle.

Context:Gonadotropin-releasing hormone (GnRH) agonist trigger mimics the natural surge more closely with both luteinizing hormone (LH) and follicle-stimulating hormone surge. The present study attempts to find whether this apparent physiological advantage translates into the better pregnancy rate.Aims:To compare the effect of GnRH agonist versus human chorionic gonadotropin (hCG) trigger on the clinical pregnancy rate (CPR) in infertile women undergoing intrauterine insemination (IUI) with oral ovulogens.Settings and Design:Retrospective analysis at a tertiary care in vitro fertilization center.Materials and Methods:The records of 280 infertile women, who underwent IUI with oral ovulogens were analyzed. Women who received 0.2 mg triptorelin (GnRH agonist (GnRHa)) as trigger were categorised in Group A (n = 129) and those who received 10,000 IU urinary hCG in Group B (n = 151). The outcome in terms of CPR was studied.Statistical Analysis Used:The quantitative variables were compared using the independent t-test/Mann–Whitney test. The qualitative variables were compared using the Chi-square test. P < 0.05 was considered statistically significant.Results:There was a trend toward better CPR in Group A (21/129 – 16.28%) than in Group B (16/151 – 10.60%), although the difference was not found to be statistically significant (P – 0.162).Conclusions:There was a trend toward better CPR with the use of GnRH agonist trigger in IUI cycles with oral ovulogens in comparison to hCG trigger, although the difference was not found to be statistically significant. Further randomized controlled trials are needed to confirm these findings.

Inflammatory Markers in Peripheral Blood Cells Cannot Predict Intrauterine Insemination Outcome: A Retrospective Cohort Study.

Background:Although infertility is known as a chronic inflammatory condition, the effect of the increased inflammatory response on IUI success is not clear. Systemic inflammation can be calculated by applying various hematological markers.Aims:We aimed to evaluate the ability of hematologic parameters of inflammation in predicting intrauterine insemination (IUI) outcome.Study Setting and Design:A total of 334 infertile couples included in this retrospective cohort study. The study population comprised of all couples who were candidates for ovulation induction and IUI due to polycystic ovary syndrome (PCOS) (n = 147) or unexplained infertility (UI) (n = 187).Materials and Methods:The inflammatory parameters in the complete blood count parameters, such as neutrophil-lymphocyte ratio, platelet lymphocyte ratio, platelet distribution width, plateletcrit were obtained on IUI day and compared between the two groups. The predictive values of these markers for IUI outcome were calculated.Results:There were 44 pregnancies (13.2%) in the whole study cohort. There were no significant differences between the pregnant and nonpregnant groups regarding the evaluated parameters (all P > 0.05). Also, no significant difference was observed between the patients with PCOS and UI in terms of those parameters. The area under receiver operating characteristic (ROC) curve analysis revealed that none of the inflammatory markers can predict pregnancy in intrauterine insemination cycles. Further prospective studies are needed to verify our findings.Conclusion:We found no relationship between the hematologic inflammatory markers and IUI outcome.Therefore these markers cannot be used for prediction of pregnancy.

Women's Reports of Barriers to and Facilitators of Oral Medication Adherence During Ovarian Stimulation: A Mixed Methods Pilot Study.

Background:Adherence to lifestyle modification recommendations remains problematic for women undergoing fertility treatment, raising concerns about the extent to which women adhere to prescribed medication regimens. Limited data have shown suboptimal oral medication adherence rates of 19% to 74%. The objective of this study was to explore what women perceive as barriers to and facilitators of oral medication adherence during fertility treatment cycles.Methods:An exploratory mixed methods pilot study was conducted among a sample of 30 women who were actively taking one to two cycles of letrozole or clomiphene citrate for ovarian stimulation in conjunction with intrauterine insemination cycles. Medication adherence barriers were measured using a 20-item survey. Medication adherence facilitators and personal experiences with fertility treatment were assessed with structured interviews. Medication adherence was assessed with electronic event monitoring.Results:The overall medication adherence median was 0.97 with a range of 0.75 to 1.00, and nine women (50%) demonstrated perfect adherence. The most commonly reported barriers were recently feeling sad, down, or blue (53%), and taking medication more than once per day (40%). Women with higher barrier scores had significantly lower medication adherence scores (p=0.02) compared to women with lower total barrier scores. Facilitators included using physical aides as reminders (60%) and establishing a daily routine (50%). No significant correlation was found between medication adherence scores and facilitators.Conclusion:The dynamic interplay between perceived barriers and facilitators and women’s medication-taking patterns could influence whether or not medication regimens are followed correctly.

Subclinical hypothyroidism of unexplained infertility patients does not affect intrauterine insemination success: A case-control study

Aim: This study aimed to assess the importance of preconceptional thyroid-stimulating hormone (TSH) values on the achievement of intrauterine insemination (IUI) in unexplained infertile patients.Materials and Methods: This study was conducted retrospectively by evaluating the medical records of euthyroid 192 patients who experienced IUI between January 2017 and December 2018. The study population was classified as serum TSH levels of 0.5-2.49 mIU/L (group A) and 2.5-4.5 mIU/L (group B). Clinical pregnancy, miscarriage and live birth rates of the groups were evaluated. Results: The demographic characteristics, laboratory levels, and cycle characteristics of the study population were similar. There were no statistically significant differences between group A and group B in terms of clinical pregnancy (11.03%, and 8.51%, respectively, p=0.62), miscarriage (3.55%, and 1.13%, respectively, p=0.65), and live birth rates (7.58%, and 6.38%, respectively, p=0.78). Conclusion: Clinical pregnancy, miscarriage, and live birth rates were similar between the two groups. We indicate that subclinical hypothyroidism does not adversely affect the clinical pregnancy, miscarriage, and live birth rates in IUI cycles of euthyroid unexplained infertile couples.

Pregnancy outcome after endometrial scratching in intrauterine insemination: A randomized controlled trial

Objective: To study the effect of local endometrial scratching on the outcomes of intrauterine insemination cycle. Design: Randomized controlled trial. Study setting: Department of Obstetrics & Gynecology, JN Medical College, Aligarh Muslim University, Aligarh. Materials and methods: A total of 77 patients were enrolled in the study. Patients undergoing controlled ovarian stimulation with intrauterine insemination were randomly allocated in two groups. In group A (n = 31), endometrial scratching was carried out on D8/D9 of same menstrual cycle in which intrauterine uterine insemination (IUI) was performed and in group B (control group; n = 31), endometrial scratching was not performed. Primary outcome was measured by pregnancy rate, while secondary outcome was measured by endometrial indices. Results: Pregnancy rate was 16.2% in group A in which endometrial scratching was carried out in IUI cycle, whereas in group B, pregnancy rate was 9.6%. Although in group A, pregnancy rate was higher when compared with group B, the results were not statistically significant (P > 0.05). The mean endometrial thickness of women in group A was 9.329 ± 0.934 which was significantly higher than endometrial thickness of group B, that is, 7.72 ± 2.0. In group A, greater number of women (41.93%, n = 13) had zone 3 endometrial flow than group B (19.35%, n = 6). However, the difference was not statistically significant (P > 0.05). Conclusion: Endometrial scratching in follicular phase in the same cycle of stimulation with IUI gives better pregnancy rate in comparison with IUI without endometrial scratching. However, the results can be of proven clinical significance only if larger group of population is studied.

Prewash and postwash total progressively motile sperm counts have poor predictive value for clinical pregnancy after intrauterine insemination.

To evaluate the predictive value of the prewash and postwash total progressively motile sperm counts (TPMSC) on clinical pregnancy after intrauterine insemination (IUI) . A review of medical records of women undergoing 2064 IUI cycles in a university hospital between April 2010 and October 2018. No pregnancies were seen when the prewash TPMSC was less than 9million or the postwash TPMSC was less than 2million. There was no correlation between TPMSC and clinical pregnancies. Further analysis was made in pregnancies after prewash TPMSC of 3-10million and more than 10million, and after postwash TPMSC of 10-100million and more than 100million. No correlation was found between TPMSC and clinical pregnancy in different strata of female age, infertility duration, type of infertility, type of IUI treatment, and the number of treatment cycles. A negative relationship was found for unstimulated IUI treatment and the number of treatment cycles. The prewash and postwash TPMSC showed no predictive value. Prewash and postwash TPMSC have poor predictive value for clinical pregnancy in IUI. Cycles with a prewash TPMSC of 10-100 million or postwash TPMSC of 3-10 million could achieve acceptable pregnancy rates with IUI.

Optimal lead follicle size for human chorionic gonadotropin trigger in clomiphene citrate and intrauterine insemination cycles: an analysis of 1,676 treatment cycles

To identify the optimal lead follicle size for hCG trigger in clomiphene citrate (CC)-intrauterine insemination (IUI) cycles. Retrospective cohort study. University-affiliated center. Patients <40 years of age with ovulatory dysfunction or unexplained infertility undergoing their first CC-IUI cycle. Ovulation induction, hCG trigger, and IUI. Clinical pregnancy rate (CPR) was the primary outcome and was plotted against lead follicle size in increments of 1 mm. Odds ratios with 95% confidence intervals for associations between lead follicle size and CPR were calculated from a multivariable logistic regression model. A receiver operating characteristic (ROC) curve was generated for CPR as a function of lead follicle size. 1,676 cycles were included. The overall CPR was 13.8% (232/1,676). There was no difference in baseline demographics or ovulation induction parameters of patients who did or did not conceive. The odds of clinical pregnancy were 2.3 and 2.2 times higher with lead follicle sizes of 21.1-22.0 mm and >22.0 mm, respectively, compared with the referent category of 19.1-20.0 mm. Lead follicle size was an independent predictor of CPR, even after accounting for confounders. A lead follicle size of 22.1 mm corresponded to a sensitivity and specificity of 80.1% and 90.4% for clinical pregnancy, respectively, with an area under the ROC curve of 0.89. hCG administration at a lead follicle size of 21.1-22.0 mm is associated with higher odds of clinical pregnancy in patients undergoing their first CC-IUI cycles for ovulatory dysfunction or unexplained infertility.

Clomiphene Citrate versus Recombinant FSH in intrauterine insemination cycles with mono- or bi-follicular development.

Objective:The present study aims to assess the success of controlled ovarian stimulation in intrauterine insemination cycles stimulated by recombinant-FSH and Clomiphene citrate for either mono- or bi-follicular development.Methods:We assessed 870 infertile patients treated with controlled ovarian stimulation in intrauterine insemination cycles at a university-based infertility clinic between January 2012 and December 2017. We compared the cycles stimulated by clomiphene citrate and recombinant-FSH in two set-ups; mono- and bi-follicular development. The main outcome measure was the clinical pregnancy rate per cycle.Results:The demographic and cycle parameters were similar between the groups, except for endometrial thickness on the day of hCG administration, which was higher in the recombinant-FSH group than the clomiphene citrate group. The overall clinical pregnancy rates in clomiphene citrate and recombinant-FSH groups were 9.8% and 10.3%, respectively (p=0.940). Regarding the entire cohort, clinical pregnancy was significantly higher in cases of bi-follicular development when compared to mono-follicular development (16.8% vs. 10.2%, respectively; p=0.009).Conclusions:Clomiphene citrate and recombinant-FSH have similar success rates in terms of clinical pregnancy, in either mono-follicular development or bi-follicular development. Clomiphene citrate and recombinant-FSH cycles resulted in comparable rates of bi-follicular development, which significantly increases clinical pregnancy rate. Clomiphene citrate and recombinant-FSH have similar success rates in terms of clinical pregnancy, in either mono-follicular development or bi-follicular development.

Study on Pregnancy Outcomes in Intrauterine Insemination Cycles with Motile Spermatozoa Insemination

Background: Intrauterine Insemination (IUI) is one of the most common assisted reproductive technology methods in the world to treat various forms of infertility. The influence of number of IUI applied with the percentage of motile spermatozoa during insemination is critical on the likelihood of a successful pregnancy. The aim of our study is to assess the results of IUI as a function of the number of IUI applied with motile spermatozoa inseminated during intrauterine insemination in couples with infertility.&#x0D; Materials and methods: This is a prospective study conducted in Surgiscope Fertility Centre, Chattogram, Bangladesh over 21 months on 596 couples who underwent IUI from 01/12/2017 to 30/09/2019. We performed semen analysis of the male partner from the couples who underwent IUI, calculated the sperm motility and the relationship between number of IUI applied with motile spermatozoa and the pregnancy rate of IUI. Multiple variables were selected such as, patient parameters like age of female, number of IUI, percentage of motile spermatozoa inseminated, endometrial thickness and ovulation induction protocol which were recorded and statistically analyzed.&#x0D; Results: Among the 596 patients, the overall success rate was 11%. The maximum number of successes were observed in patients with 3 IUI applications whereas the success rate was lower in comparison with decreasing IUI applications. The regression between the success and number of insemination and age indicate that there is a statistically significant positive relationship between number of inseminations completed and the rate of successful pregnancy, but no significant relationship between the number of prewash sperm and successful pregnancy. These could be due to lower population size. As an ovulation inducing agent, a 12.42% success rate was observed among the patients administered with FSH whereas 9.28% was observed for patients administered with GONAL F. The mean endometrial thickness was observed to be 8.914 mm with a minimum thickness of 4.5 mm and a maximum thickness of 19 mm.&#x0D; Conclusion: The rationale for the use of insemination is to increase gamete density at the site of fertilization. This revealed that intrauterine insemination should be a firstchoice treatment rather than more invasive and expensive techniques of assisted reproduction in cases of cervical, unexplained and moderate male factor subfertility.&#x0D; Chatt Maa Shi Hosp Med Coll J; Vol.19 (2); July 2020; Page 41-45

Is intrauterine insemination a viable treatment option for women over 43years old? An analysis by ovarian stimulation protocol and sperm source.

The aim of this study was to determine how female age at the end of the reproductive spectrum effects success of natural cycle intrauterine insemination (IUI) or IUI in combination with ovarian stimulation. We performed a retrospective cohort study of women 43years of age and older at the time of IUI in a single academic fertility center between January 2011 and March 2018. Primary outcomes were both pregnancies and live births per cycle of IUI. Data are presented as percentage or mean ± SD. Fisher exact and chi-squared analyses were performed. There were 9334 IUI cycles conducted during the study period. Of these cycles, 325 IUIs (3.5%) were for women aged 43years and over at the time of insemination (43.6 ± 0.8, range 43 to 47years). Analysis of these 325 IUI cycles revealed 5 biochemical pregnancies (1.5%) and only 1 live birth (0.3%). The pregnancy rate did not differ between IUIs using donor sperm (N = 1/49, 2.0%) compared to IUIs with partner sperm (N = 4/276, 1.4%). The pregnancy rate did not differ between IUIs with gonadotropins (N = 2/211, 0.9%), clomiphene or letrozole (N = 2/78, 2.6%), or natural cycle (N = 1/36, 2.8%). The use of intrauterine inseminations in women 43years of age and older is an ineffective treatment strategy. This is irrespective of the use of ovarian stimulation or donor sperm. Costly gonadotropin injections did not increase the chance of pregnancy nor did oral medication when compared to natural cycle IUIs.

Does ovarian stimulation benefit ovulatory women undergoing therapeutic donor insemination?

To compare clinical and ongoing pregnancy after natural cycle (NC) intrauterine insemination (IUI) versus ovarian stimulation (OS) IUI in ovulatory women undergoing therapeutic donor insemination (TDI). Retrospective cohort. Single infertility center. A total of 76,643 IUI cycles in patients treated with intrauterine insemination were examined. Women undergoing TDI in the absence of diagnosed female factor infertility were included. NC TDI or OS TDI with either clomiphene citrate or letrozole. Clinical and ongoing pregnancies were analyzed by generalized estimating equations adjusting for age, body mass index, total motile sperm at time of insemination and cycle number. Ongoing multiple gestations were examined as a secondary outcome. Six thousand one hundred ninety-two TDI cycles from 2,343 patients (711 patients without repeated IUI cycles) met inclusion criteria and were available for analysis (3,837 NC and 2,355 OS). There was no difference in mean age between the two groups (NC, 34.2 years vs. OS, 34.3 years). Probability of clinical and ongoing pregnancy was higher in the OS cohort compared with the NC cohort (OS, 22.4% vs. NC, 18.7% and OS, 15.4% vs. NC, 14.9%, respectively). However, OS significantly increased ongoing multiple gestations (OS, 10.8% vs. NC, 2.4%). Ovarian stimulation in TDI cycles resulted in a <4% increase in clinical and <1% increase in ongoing pregnancy, and more than fourfold increase in ongoing multiple gestations. Natural cycle IUI should be considered as a first-line treatment for ovulatory women who need donor insemination.

A patient-specific model combining antimüllerian hormone and body mass index as a predictor of polycystic ovary syndrome and other oligo-anovulation disorders

To determine whether a patient-specific predictive model combining antimüllerian hormone (AMH) levels and body mass index (BMI) can aid in the diagnosis of polycystic ovary syndrome (PCOS) and other ovulatory dysfunction disorders (OVDYS) among infertile women. Retrospective cohort study. Academic fertility center. One thousand and ten infertile women undergoing 3,160 intrauterine insemination (IUI) cycles, stratified by diagnosis in three groups: PCOS, OVDYS, and other etiologies. Ovulation induction followed by IUI or ultrasound-monitored natural cycles. The probability of either PCOS or OVDYS diagnosis based on AMH levels alone and a patient-specific predictive model that combines serum AMH and patient's BMI. Median and interquartile range (IQR) for the serum AMH levels (ng/mL) were the highest in women with PCOS, and lowest in those with other infertility causes. Overall, for every 1 ng/mL increase in AMH, the odds of PCOS and OVDYS versus other causes increased by 55% and 24%, respectively. Postestimation from multivariate logistic regression models showed that PCOS diagnosis can be predicted with lower AMH values in women with a higher BMI compared with the AMH values predicting PCOS in normal-weight or underweight patients. The receiver operating characteristic curves reinforced these findings, and the best cutoffs for PCOS diagnosis were 7.5, 4.4, and 4.1 ng/mL for women belonging to the BMI groups 18.5-24.9, 25.0-29.9, and ≥30.0 kg/m2, respectively. Taking into account AMH and BMI, we developed a model that predicts the probability of an oligo-anovulation diagnosis, thus facilitating patient-specific counseling in the infertility setting.

Short-term weight change and live birth among women with unexplained infertility and polycystic ovary syndrome undergoing ovulation induction

To determine if short-term weight change among women with unexplained infertility (UI) and polycystic ovary syndrome (PCOS) undergoing ovulation induction is associated with live birth. Secondary analysis of randomized trials. Multicenter fertility trial sites. A total of 900 women with UI and 750 women with PCOS. Live birth. Weight assessment at enrollment and start of up to 4-5 cycles of clomiphene, letrozole, or gonadotropins and intrauterine insemination for women with UI and clomiphene or letrozole with regular intercourse for women with PCOS. Weight data were available for 856 women with UI and 697 women with PCOS. Mean weight change was -0.2 ± 0.3 kg among women with UI and +2.2 ± 0.2 kg among women with PCOS and did not differ based on treatment allocation. There were 115 women with PCOS (16.4%) who gained ≥3 kg. Increased body mass index and three or more cycles were associated with weight gain in women with PCOS. There was no difference in live birth rate among women with PCOS and ≥3 kg weight gain and women with PCOS who did not gain weight. Women with PCOS gained an average of 2.2 kg regardless of the medication received, whereas women with UI experienced no short-term weight change during ovulation induction. Weight gain in women with PCOS was not associated with live birth rate.

Pregnancy rate of intrauterine insemination (IUI) - is it affected by inseminated motile sperm count and stimulation protocol?

Objective To compare IUI pregnancy rate by partner and donor sperm according to inseminated motile sperm count and ovulation induction protocol Design Retrospective study by a private IVF center Materials and methods 3,028 IUI cycles (2,284 cycles with partner sperm and 744 cycles with donor sperm) were analyzed. Ovulation induction was done using 5 mg of letrozole (Let) on cycle days 3 through 7, with 250 mcg recombinant hCG injected as instructed after follicle monitoring is done on day 12. A sequential (Seq) stimulation involves Let protocol, followed by 150 IU FSH daily from cycle day 7. Ultrasound monitoring is done on day 10 to determine further medication dosing, GnRH antagonist initiation, and monitoring. A controlled ovarian hyperstimulation (COH) cycle involves daily FSH injections at doses between 150 and 300 IU FSH, with monitoring beginning on day 7 to determine further medication dosing, GnRH antagonist initiation, and monitoring. All IUI procedures were performed approximately 36 hours after trigger. Pre-washed frozen sperm was thawed by agent's thawing protocol. Total motile sperm for insemination was counted after finishing sperm wash process. The statistical analysis was performed using t-test, chi-square, or z-test. A p value of Results IUI pregnancy rate by using partner sperm was significantly lower (n=106, 3.8%) when inseminated motile sperm is Conclusions IUI pregnancy rate is not affected by sperm count if at least 3 million motile sperm are inseminated. Pregnancy rate from natural cycle is low in both partner sperm and donor sperm cycle. There is no significant difference of pregnancy rate between ovulation induction protocols although the pregnancy rate in Let group is slightly lower than that in COH or Seq group.

Effect of gonadotropins and endometrial thickness on pregnancy outcome in patients with unexplained infertility or polycystic ovarian syndrome undergoing intrauterine insemination.

ObjectiveThe purpose of this study was to investigate the effect of gonadotropin dose and endometrial thickness (EMT) on pregnancy outcome in patients undergoing intrauterine insemination (IUI).MethodsWe retrospectively analyzed data from 361 patients with unexplained infertility or polycystic ovarian syndrome (PCOS) who underwent 930 IUI cycles treated with gonadotropins. Then, we measured the effects of gonadotropins and EMT on the clinical pregnancy rate. Finally, we assessed the association of various doses of gonadotropins on EMT.ResultsThe dose of gonadotropins given and thickness of the endometrium were higher in the pregnancy group than in the nonpregnancy group (636.0 vs. 600.0 IU for gonadotropin dose; 9.15 vs. 8.70 mm for EMT). Clinical pregnancy rates were significantly improved by increasing the dose of gonadotropins (9.1%, <450 IU; 16.2%, 450–599 IU; 18.6%, 600–749 IU, and 17.3%, ≥750 IU), or by increased EMT (0%, <5.0 mm; 12.2%, 5.0–6.9 mm; 15.5%, 7.0–14.0 mm; and 33.3%, >14.0 mm).ConclusionIncreasing the dose of gonadotropins to stimulate one follicle to develop may benefit endometrial proliferation and improve IUI outcomes.
