Incidence of and factors associated with emergency caesarean section in pregnant women with gestational diabetes mellitus: A retrospective cohort study.

The incidence of factors associated with emergency cesarean section (ECS) in patients with gestational diabetes mellitus (GDM) have not been well investigated. We conducted a retrospective cohort study of patients diagnosed with GDM between 2011 and 2020 at a tertiary care hospital in Japan. Clinical data, vital signs, and laboratory results of the patients were collected from electronic medical records. We constructed a multivariate logistic regression model to identify the clinical characteristics associated with ECS. We included 1189 patients diagnosed with GDM, the mean maternal age was 33 years, and 507 (42.6%) patients were aged ≥35 years. In total, 114 patients underwent ECS (9.6%). The previous assisted reproductive technology (ART) use (odds ratio [OR], 1.81; 95% confidence interval [CI], 1.12-2.93), previous artificial abortion (OR, 1.94; 95% CI, 1.13-3.33), high pre-pregnancy body mass index (BMI) (OR, 1.07; 95% CI, 1.02-1.11), and late diagnosis of GDM (OR, 1.02; 95% CI, 1.003-1.05) were independently associated with ECS. One of every 10 GDM patients required ECS. Previous ART use, previous artificial abortion, high pre-pregnancy BMI, and late diagnosis of GDM were risk factors for ECS in GDM patients.

ICSI using testicular spermatozoa after failure of ICSI with ejaculated spermatozoa could be a good choice: A propensity score‐matched cohort study

AbstractBackgroundEjaculated spermatozoa are considered to possess a higher fertilisation potential than testicular spermatozoa. In selected cases, the use of testicular spermatozoa from non‐azoospermic infertile men resulted in a higher implantation and pregnancy rate than the use of ejaculated spermatozoa.ObjectiveThe primary objective was to compare the live birth rate and cumulative live birth rate between couples with failed intracytoplasmic sperm injection procedure using ejaculated spermatozoa who subsequently had an intracytoplasmic sperm injection cycle with testicular spermatozoa and those who subsequently had an intracytoplasmic sperm injection cycle with ejaculated spermatozoa. The secondary objective was to determine the indications for the use of testicular spermatozoa after intracytoplasmic sperm injection failure with ejaculated spermatozoa.Materials and methodsA retrospective study of matched couples using propensity score matching analysis was performed. After an intracytoplasmic sperm injection failure (cycle_1), intracytoplasmic sperm injection with either ejaculated spermatozoa (ejaculated sperm group), or testicular spermatozoa (testicular sperm group), was performed (cycle_2). The matching was on intracytoplasmic sperm injection performed in cycle_1 according to spermatozoa used (testicular or ejaculated) in cycle_2. Logistic regression was used to evaluate the influence of sperm origin on cumulative live birth rate. Univariate analysis on parameters of cycle_1 was used to identify the prognostic factors to propose an intracytoplasmic sperm injection with testicular spermatozoa in case of cycle_1 failure. The study outcomes were live birth rate and cumulative live birth rate.ResultsAmong the 6034 couples available, 63 were selected to constitute the testicular sperm group and 63 were selected by propensity score matching to constitute the ejaculated sperm group. After matching, the DNA fragmentation index was higher in the testicular sperm group (13.43% ± 9.65% vs. 8.93% ± 4.47%, p = 0.013); no significant difference was observed for the fertilisation rate, the number of obtained embryos, blastulation rate and frozen embryo rate. In cycle_2, the live birth rate was higher in the testicular group (22.2% vs. 0.0%, p < 0.001), as was the cumulative live birth rate (25.4% vs. 6.3%, p = 0.065). The prognostic factors identified for the proposal of intracytoplasmic sperm injection procedure with testicular spermatozoa after intracytoplasmic sperm injection failure with ejaculated spermatozoa were: teratozoospermia, cryptozoospermia and high DNA fragmentation index.DiscussionAccording to the present study and current knowledge, the use of testicular spermatozoa after failed intracytoplasmic sperm injection procedure in non‐azoospermic men could be proposed instead of sperm donation in case of high sperm DNA fragmentation index, cryptozoospermia and teratozoospermia. A good oocyte response to ovarian stimulation during the previous assisted reproductive technology attempt will increase the chance of success. Although the main limitation of the current study is its retrospective nature, the use of the propensity score matching to perform causal inference study increases its reliability.ConclusionThe present study supports that the use of testicular spermatozoa outside the classical indication of azoospermia is a good option when the indication is well established. However, before proposing a testicular biopsy, an improvement in sperm characteristics should be considered by treating the causes of sperm alteration.

Maternal Body Mass Index Trends and Weight Gain in Singleton Pregnancies at the Time of Fetal Anatomic Survey: Changes in the Last Decade and New Trends in the Modern Era.

(1) Background: the worldwide impact of overweight and obesity is rising, increasingly resembling an epidemic (a price we have to pay for our new way of living). (2) Methods: our study aims to evaluate the temporal trends and patterns of singleton pregnant women's BMI (body mass index) in our region during a 12-year time frame between 2010 and 2021. (3) Results: We noticed a statistically significant difference between the BMIs of nulliparous and multiparous women and a significantly increased pregestational BMI in women with previous ART (assisted reproductive technology) procedures. Smoking pregnant women had a higher second trimester weight gain, regardless of parity. Women with folic acid supplementation alone had a higher BMI than those with folic acid and multivitamin intake. The weight of both nulliparous and multiparous women with chronic hypertension was statistically significantly higher in all three timeframes. Global weight gain did not reveal any statistically significant changes concerning women with pregestational diabetes, regardless of parity and the pregnancy trimester. (4) Conclusions: our article describes the trends in obesity and overweight in our middle-income country, in which this pathology is continuously growing, negatively influencing our reproductive-aged women and future generations.

Prevalence of Psychological Stress Among Women Attending the Assisted Reproductive Technology (ART) Unit at King Abdulaziz Medical City: A COVID-19 Pandemic Experience.

Aim The present study aimed to measure the prevalence of psychological stress among women attending the Assisted Reproductive Technology (ART) unit in King Abdulaziz Medical City during the COVID-19 pandemic. Method The study adopted a descriptive cross-sectional design and was conducted between January 2020 and December 2022. A sample of 104 women attending the ART unit were recruited in this study. To collect data, the researchers developed a study questionnaire that consisted of 26 items. Nine items were designed to measure the participants' demographic characteristics, and 17 items were designed to depict their responses related to psychological stress during the COVID-19 pandemic. Data were analyzed using the Statistical Product and Service Solutions (SPSS) (v. 26l; IBM SPSS Statistics for Windows, Armonk, NY). Chi-square and t-tests were used to assess the association between stress and sociodemographics. Results The findings of the study showed an overall prevalence of 86.53% (n=90).Levels of psychological stress were moderate (34.62%, n=36), severe (39.42%, n=41), and extremely severe (12.50%, n=13). The study found that there is a significant statistical interaction between the number of previous ART attempts and psychological stress (p=0.0019). Conclusion The study concluded that women attending the ART unit at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia, were experiencing high levels of psychological stress, and these levels were affected by the number of previous ART attempts.

Assisted reproductive technology treatment and risk of multiple sclerosis – a Danish cohort study

To compare the incidence of multiple sclerosis (MS) among women who had undergone assisted reproductive technology (ART) treatment with the women who had conceived a child without previous ART treatment. A register-based nationwide cohort study. Women with a first ovarian stimulation cycle before invitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) (i.e., ART treatment) recorded in the Danish IVF register between 1996 and 2018; and women recorded in the Danish Medical Birth Register with the birth of their first child where date of conception is between 1996 and 2018. The cohort was observed until March 10,2021. Mainly included IVF, ICSI, and fresh embryo transfer with hormone stimulation. A diagnosis of MS recorded in the Danish Multiple Sclerosis Registry. Crude and adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) were calculated. A total of 585,716 women were included in the cohort of which 63,791 (11%) were exposed to at least one initiated IVF or ICSI cycle during the study period. Cycles with oocyte donation were excluded. The median follow-up time for the entire cohort was 12.4 years (Q1-Q3= 6.6-18.1). Compared with women conceiving without previous ART, ART treated women were older (31.8 years vs. 27.5 years), more often had a university degree (45% vs. 36%), and more often had received other fertility treatments than IVF or ICSI before cohort entry (26% vs. 3%). We found no association between incident MS and exposure to ART compared with non-ART pregnancy (aHR=1.08; 95 % CI, 0.93-1.25). An analysis following intention-to-treat principle on a propensity score matched sub cohort confirmed our results. In subgroup analysis including all ART cycles among the ART treated women, we found no increased risk of MS within 2 years of ART cycle start for successful ART cycles (pregnancy) compared with failed ART cycles (no pregnancy) (aHR=1.01; 95% CI, 0.58-1.76). We found a non-significant trend toward increased risk of MS with increasing numbers of ART cycles although based on small numbers. Women treated with ART do not seem to be at increased risk of developing MS compared with the women not exposed to ART.

Impact of endometrial scratching on reproductive outcome in patients: A systematic review and meta-analysis.

Background:Endometrial scratching (ES) has demonstrated initial success in women with recurrent implantation failure, but the effect in women with 1 previous assisted reproductive technology (ART) failure is unknown. This meta-analysis aimed to evaluate the impact of ES as a treatment in clinical outcomes for women with at least 1 failed in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)/Intrauterine Insemination (IUI).Methods:PubMed, Medline, Embase, Cochrane Library, Web of Science, CNKI, and EMCC databases were searched for randomized controlled trial studies utilizing endometrial scratching for infertility women with at least 1 failed assisted reproductive technology (ART) to collect pregnancy outcomes, including clinical pregnancy rate (CPR), embryo implantation rate (IR), miscarriage rate (MR), live birth rate (LBR), and multiple pregnancy rate (MPR).Results:Sixteen randomized controlled trial (RCT) studies were included in this meta-analysis, including 1770 women in the intervention group and 1934 women in the control group. Overall, the CPR, IR and LBR were significantly higher in the intervention group than in the control group (for CPR, n = 1430, 16 studies, P = .0002, risk ratio (RR) = 1.59, 95% confidence interval [CI] [1.24, 2.03]; for IR, n = 859, 10 studies, P = .0003, RR = 1.67, 95% CI [1.26, 2.21]; for LBR, n = 156, 6 studies, P = .0005, RR = 1.59, 95% CI [1.22, 2.06]). Nonetheless, there was no significant difference in MR (n = 344, 11 studies, P = .62, risk ratio (RR) = 0.92, 95% confidence interval [CI] [0.66, 1.29]) and MPR (n = 98, 3 studies, P = .39, risk ratio (RR) = 0.81, 95% confidence interval [CI] [0.51, 1.30]) between the intervention group and the control group.Conclusion:Endometrial scratching is considered to enhance the reproductive outcomes of embryo implantation. Additional randomized controlled studies are recommended to identify the appropriate time of invasion and the applicable population to confirm whether it can become a routine operation.

Effects of Melatonin on the Transcriptome of Human Granulosa Cells, Fertilization and Blastocyst Formation.

Melatonin is a promising reagent that can improve assisted reproductive technology (ART) outcomes in infertility patients. However, melatonin is not effective for all infertile patients, and it remains unclear for which patients melatonin would be effective. This study examined the effects of melatonin on ART outcomes and examined its mechanisms. Melatonin increased the fertilization rate in patients whose fertilization rates in the previous cycle were less than 50%, but not in patients whose fertilization rates were more than 50% in the previous cycle. Melatonin increased the blastocyst formation rate in patients whose embryo development rates in the previous cycle were less than 50%, but not in patients whose embryo development rates were more than 50% in the previous cycle. To clarify its mechanisms, transcriptome changes by melatonin treatment in granulosa cells (GCs) of the patients were examined by RNA-sequence. Melatonin treatment altered the transcriptomes of GCs of patients with poor ART outcomes so that they were similar to the transcriptomes of patients with good ART outcomes. The altered genes were associated with the inhibition of cell death and T-cell activity, and the activation of steroidogenesis and angiogenesis. Melatonin treatment was effective for patients with poor fertilization rates and poor embryo development rates in the previous ART cycle. Melatonin alters the GCs transcriptome and, thus, their functions, and this could improve the oocyte quality, leading to good ART outcomes.

DNA fragmentation index and human papilloma virus in males with previous assisted reproductive technology failures.

This study was designed to evaluate the prevalence of Human Papilloma Virus (HPV) in semen and document the cycle outcomes in couples with previous intra-cytoplasmic sperm injection (ICSI) failures. One hundred and seventeen couples with at least two ICSI attempts were included in the study. HPV infection in semen and DNA fragmentation in samples were analyzed by commercially available kits. The percentage of spermatozoa with fragmented DNA (DNA fragmentation index: DFI) was determined during fluorescence microscopic examination as previously described. The cycle outcomes of couples with or without HPV infected male partners were recorded. According to our results, the prevalence of HPV was 7.7% in asymptomatic males with at least two previous ICSI failures. The increased DFI (>30%) was observed in 82.9% of the cases. In HPV-positive cases significantly lower number of good quality embryos were obtained. The implantation and pregnancy rates were similar in infected and non-infected males (p>0.05). The early miscarriage rate was slightly higher in HPV- positive group (33% vs. 10%, p>0.05). In cases with previous ICSI failures, the prevalence of HPV infection in semen is not higher than previously reported infertile populations. The reproductive outcome might be impaired in HPV-positive semen due to lower number of good quality embryos, which needs to be clarified by further large population-based studies.

Association between The Number of Retrieved Mature Oocytes and Insulin Resistance or Sensitivity in Infertile Women with Polycystic Ovary Syndrome.

BackgroundThe objective of this study was to describe the association between luteinizing hormone (LH)/ follicle-stimulating hormone (FSH) ratio and demographic variables and maturation stage of oocytes in insulin- resistant and insulin-sensitive patients with polycystic ovary syndrome (PCOS) in comparison with control group.Materials and MethodsIn this case-control study, 60 patients with in vitro fertilization (IVF)/intracytoplas- mic sperm injection (ICSI) indication were subdivided into 3 groups as follow: 20 subjects were assigned to control (fertile women with male infertility history) group, 20 subjects with PCOS were insulin resistant (IR) and 20 subjects with PCOS were insulin sensitive (IS). After puncture, retrieved oocytes were classified into metaphase II (MII) as mature and in metaphase I (MI) or germinal vesicle stage (GV) as immature. Regres- sion analyses were used to explore the association between MII oocyte number and demographic and clinical variables.ResultsLH/FSH ratio was significantly higher in PCOS-IR women compared to controls but not significantly dif- ferent from that of PCOS-IS group. PCOS-IR women had lower MII oocyte number compared with that of controls. According to multiple regression analysis, the number of previous assisted reproductive technology (ART) cycles was negatively associated with the number of MII oocytes.ConclusionInsulin resistance can be associated with reductions in MII oocyte number in patients with PCOS.

Predicting live birth for poor ovarian responders: the PROsPeR concept.

A number of live-birth predictive models are available, and despite clinical interest these are rarely used owing to poor performance. In addition, no predictive models specifically for poor ovarian responders (POR) are available. The aim of the current project was to develop a clinically applicable tool for predicting live birth for PORs receiving recombinant human FSH [r-hFSH]. A model was developed to predict live birth in PORs receiving r-hFSH, using data from the ESPART trial. Initially, two models were developed separately: one for patients with data from a previous assisted reproductive technology (ART) cycle and one for ART treatment-naïve patients. Subsequently, the simplified Poor Responder Outcome Prediction (PROsPeR) concept was derived. PROsPeR considers three predictors and categorizes PORs into three scores, with predicted the live-birth rate divided by three with each worsening category. When adequately calibrated, a discrimination score up to area under the receiver operating characteristic (AUCROC) (95% CI) of 0.84 (0.79 to 0.88) was observed, which is superior to previously published models. Lower discriminations were observed when the PROsPeR model was used to evaluate the patients who received both r-hFSH and recombinant human LH in the ESPART study (AUCROC [95% CI] 0.66 [0.61 to 0.71]) and when all the patients included in the ESPART study were evaluated (AUCROC [95% CI] 0.68 [0.61 to 0.72]). This model, specific to PORs receiving r-hFSH, constitutes the best compromise between precision and simplicity, and is suitable for routine practice.

No advantage of fresh blastocyst versus cleavage stage embryo transfer in women under the age of 39: a randomized controlled study.

Is there a difference in implantation and pregnancy rates between embryos transferred electively at cleavage or blastocyst stage in infertile women ≤ 38years with at least four zygotes on day 1 post retrieval? A randomized clinical trial was conducted in a single tertiary care hospital with a sample size of 194 patients in each arm for a total population of 388 women. Patients less than 39years of age with more than three fertilized oocytes and less than four previous assisted reproductive technology (ART) attempts were inclusion criteria. The two groups were similar for age, years of infertility, indication to treatment, basal antimüllerian hormone and FSH, number of previous ART cycles, primary or secondary infertility, type of induction protocol, days of stimulation, total gonadotrophin dose, and estradiol (E2) and progesterone (P) levels at trigger. No statistically significant differences were found in terms of number of retrieved oocytes, inseminated oocytes, fertilization rate, canceled transfers (7.73% in blastocyst and 3.61% in cleavage stage group), and cycles with frozen embryos and/or oocytes. Although a higher number of fertilized oocytes were in the blastocyst stage group (6.18 ± 1.46 vs 5.89 ± 1.54, p = 0.052), a statistically greater number of embryos/randomized cycle were transferred at cleavage stage (1.93 ± 0.371) compared with the number of transferred blastocysts (1.80 ± 0.56), probably due to the number of embryos not reaching blastocyst stage (3.09%). The implantation rate (28.37 vs 25.67%), pregnancy rate per cycle (36.06 vs38.66%), transfer (39.66 vs 40.11%), spontaneous abortions (19.72% vs 12.00%), delivery rate per cycle (27.84 vs 32.99%), and transfer (30.17 vs 34.22%) were not significantly different between the blastocyst and cleavage stage groups. The twin delivery rate was higher in the blastocyst stage group, although not significant (42.59 vs 28.12%). The mean numbers of frozen blastocyst (2.30 ± 1.40 vs 2.02 ± 1.00) and frozen oocytes (7.09 ± 3.55vs 6.79 ± 3.26) were not significantly different between the two groups. Fresh blastocyst-stage transfer versus cleavage-stage transfer did not show any significant difference in terms of implantation and pregnancy rate in this selected group of patients. A high twin delivery rate in both groups (35.59%) was registered, and although not significant, they were higher in the blastocyst transfer group (42.59 vs 28.12%). Our conclusion supports considering single embryo transfer (SET) policy, even in cleavage stage in patients younger than 39years with at least four zygotes. ClinicalTrials.gov registration number NCT02639000.

Assisted reproductive technology treatments and quality of life: a longitudinal study among subfertile women and men

Quality of life (QoL) may represent a comprehensive indicator for the assessment of the psychological impact of complex clinical conditions, such as infertility. Infertile women have a worse QoL compared to both infertile men and non-infertile controls. However, the initial phases of infertility treatments have been frequently investigated using cross-sectional study designs. This prospective longitudinal study aimed at assessing the health-related QoL change across different phases of assisted reproductive technology (ART) treatments in subfertile women and men. Eighty-five subfertile women and men undergoing ART cycles were assessed at the beginning of the ovarian stimulation, during oocyte retrieval before discharging, and around 14days after the embryo transfer. QoL was assessed through the Short Form 36. Irrespective of the cause of infertility, work status, and age, QoL levels decreased from the first to the third assessment, and women scored significantly lower than men to each QoL indicator. Additionally, a higher number of previous ART failures had a negative impact on QoL, irrespective of gender and the phase of treatment. ART outcome marginally affected women's QoL across time. Infertile women have a worse QoL throughout all phases of ARTs compared to men, and this difference increases in infertile patients with more than one previous ART failure.

What do Infertile Women Think about Oocyte Reception, Oocyte Donation, and Child Adoption?

Purpose The views of infertile couples regarding oocyte donation by third parties and adoption are unknown, as these may be interpreted as a final closure of the available options for conception. This study aimed to determine the acceptance of oocyte donation, oocyte reception, and child adoption of infertile women who submitted to assisted reproductive technology (ART) treatment Methods Sixty-nine women who were under treatment for infertility and submitted to ART procedures were included in this cross-sectional study. They were evaluated using semi-structured questionnaires administered during ovulation induction in a treatment cycle. Marital status, religion, years of schooling, occupation, type of infertility, age, duration of infertility, number of previous ART cycles, mean oocyte number per cycle, and mean number of embryos per cycle had no influence on a woman's acceptance of oocyte donation or oocyte reception. Results More than 90% of the patients thought that the subject of "adoption" should be brought up during their ART treatments, although they preferred to discuss this topic with psychologists, not doctors. Women with occupations were more willing to consider adoption. Conclusion The opinions of these patients on these issues seem to be based on personal concepts and ethical, religious, and moral values. Women preferred to discuss adoption with psychologists rather than doctors.

Is human chorionic gonadotropin supplementation beneficial for frozen and thawed embryo transfer in estrogen/progesterone replacement cycles?: A randomized clinical trial.

AimHuman chorionic gonadotropin (hCG) is used frequently for luteal support in fresh in vitro fertilization cycles as it induces progesterone secretion from the ovaries after oocyte retrieval and modulates the endometrium for implantation in fresh cycles. In contrast, hCG is not usually used for the transfer of cryopreserved‐thawed embryos in estrogen/progesterone replacement cycles because ovulation is suppressed. However, several studies have shown that luteinizing hormone and hCG receptors are present in the human endometrium and that hCG can directly induce the decidualization of endometrial stromal cells in vitro. Thus, this study evaluated whether hCG supplementation can be beneficial for cryopreserved‐thawed embryo transfer in estrogen/progesterone replacement cycles.MethodsOne‐hundred‐and seventy‐three cryopreserved‐thawed embryo transfer cycles with estrogen/progesterone replacement were divided randomly into two groups. Transdermal oestradiol was used in combination with vaginal progesterone suppositories for HR. The embryo transfer was performed on day 17 and/or day 20 of the HR therapy cycle in both groups. In Group A, 3000 IU of hCG was administered on days 17, 20, and 23. In Group B, hCG was not used.ResultsThere was no significant difference in the average age of the patients, the average number of previous assisted reproductive technology cycles, or the average number of embryo transfers between the two groups. The rates of pregnancy and implantation per embryo were 37.2% and 25.3%, respectively, in Group A and 35.6% and 21.7%, respectively, in Group B. The pregnancy and implantation rates were similar in both groups.ConclusionSupplementation with hCG is not beneficial for cryopreserved‐thawed embryo transfer in estrogen/progesterone replacement cycles.

Prognostic factors for patients undergoing vitrified-warmed human embryo transfer cycles: a retrospective cohort study

We examined the prognostic factors for pregnancy in 210 vitrified-warmed embryo transfer (ET) cycles in 121 patients. The univariate analysis showed that age, gravida, the number of cycles associated with infertility caused by endometriosis, the number of previous assisted reproductive technology (ART) treatment cycles, and the number of ICSI procedures were significantly lower in pregnant cycles compared with non-pregnant cycles. The percentages of ET using at least one intact embryo and of ET using at least one embryo that had developed further after warming were significantly higher in pregnant cycles compared with non-pregnant cycles. Multivariate logistic regression analysis showed that previous ART treatment cycles, ET with at least one intact embryo, and ET using at least one embryo that had developed further were independent prognostic factors for pregnancy in vitrified-warmed ET cycles. We conclude that fewer previous ART treatment cycles, ET using at least one intact embryo, and ET with embryos that have developed further after warming might be favourable prognostic factors for pregnancy in vitrified-warmed ET cycles.

Characteristics and clinical outcomes of patients undergoing fertility treatment by double gamete donation

The number of women receiving in vitro fertilization cycles with both oocyte and sperm donation (double donation; DD) has grown globally in the last decade. The aim of this retrospective study, which included 1139 DD cycles, was to describe the characteristics of patients receiving DD and the outcomes of this assisted reproductive treatment. A cluster analysis identified couple ‘status’ as the main variable in dividing patients into categories. Three such status groups were identified for further analysis: (i) single women (SW), that is women without a partner either male or female; (ii) women with a male partner (MP); (iii) women with a female partner (FP). SW were significantly older (43.9) than patients with a MP (40.4) and a FP (41.3). Women with a male or FP comprised fewer patients with no previous assisted reproductive technology cycles (18.4% and 25.7%, respectively) compared to SW (43.5%). The proportion of patients without children before treatment was significantly different between SW (94.7%) and women with a MP (87.2%). There were no differences in clinical outcomes among the three groups studied. Biochemical pregnancy rate was 58.2% in SW, 58.4% in women with a MP and 64.9% in women with a FP. For the same groups, clinical pregnancy rates were 50.2%, 49.4% and 55.4%, while ‘take-home baby’ rates were 36.6%, 38.9% and 40.3%. Multiple birth and caesarean section rates were not different among the groups, with twinning rates 21.1%, 30.4% and 36%, and caesarean section rates 25.6%, 24% and 26.4% for SW, women with MP and women with FP, respectively.

Methotrexate does not affect ovarian reserve or subsequent assisted reproductive technology outcomes.

The purpose of this research was to study whether methotrexate (MTX) as treatment for ectopic pregnancy (EP) impacts the future fertility of women undergoing assisted reproductive technology (ART) METHODS: In a systematic review and multi-center retrospective cohort from four academic and private fertility centers, 214 women underwent an ART cycle before and after receiving MTX as treatment for an EP. Measures of ovarian reserve and responsiveness and rates of clinical pregnancy (CP) and live birth (LB) were compared in the ART cycles prior and subsequent to MTX. Seven studies were identified in the systematic review, and primary data from four institutions was included in the final analysis. Women were significantly older in post-MTX cycles (35.3 vs 34.7years). There were no differences in follicle stimulating hormone, antral follicle count, duration of stimulation, oocytes retrieved, or fertilization rate between pre- and post-MTX cycles. However, post-MTX cycles received a significantly higher total dose of gonadotropins (4206 vs 3961IU). Overall, 42% of women achieved a CP and 35% achieved a LB in the post-MTX ART cycle, which is similar to national statistics. Although no factors were identified that were predictive of LB in young women, the number of oocytes retrieved in the previous ART cycle and current AFC were predictive of LB (AUC 0.76, 0.75) for the older women. MTX does not influence ovarian reserve, response to gonadotropin stimulation, and CP or LB rate after ART. MTX remains a safe and effective treatment option for women with asymptomatic EPs.

Does infertility history affect the emotional adjustment of couples undergoing assisted reproduction? the mediating role of the importance of parenthood.

ObjectivesThe emotional adjustment of couples undergoing assisted reproductive technology (ART) treatments has been widely studied; however, it remains unclear whether infertility history contributes to couples' adjustment. This study examined the impact of infertility history (duration of infertility and number of previous ART treatment cycles) on the emotional adjustment of couples undergoing an ART cycle and the mediating effect of importance of parenthood on that association.MethodsIn this cross‐sectional study, 70 infertile couples (70 women and 70 men) completed self‐report questionnaires assessing emotional adjustment and infertility stress during the hormonal stimulation phase of an ART cycle. Path models accounting for the dyadic nature of the data examined the direct and indirect effects (by affecting representations about parenthood and childlessness) of infertility history on emotional adjustment.ResultsThe number of previous cycles affected men's, but not women's, emotional adjustment by affecting the representations on the importance of parenthood and of childlessness. Duration of infertility had the opposite effect, as couples with longer infertility reported heightened importance of parenthood, which negatively affected their emotional adjustment.ConclusionsInfertility history was associated with emotional adjustment in men and women, although these associations were complex. The results suggest that progression through treatment is harder for those men and women who attribute higher importance to being parents, which is aggravated by longer infertility. Statement of contribution What is already known about the subject? Infertility is an unexpected and stressful life eventAssisted reproductive treatments (ART) are emotionally demanding What does this study add? The influence of infertility history on adjustment is mediated by the importance of parenthoodMen and women are affected by their past history of infertility differently

Higher pregnancy rates using testicular sperm in men with severe oligospermia

To evaluate assisted reproductive technology (ART) outcomes using testicular sperm in oligospermic men who previously failed to achieve paternity using TUNEL-positive ejaculated sperm. Retrospective cohort. Academic medical center. Twenty-four oligospermic men who failed one or more ART cycles using ejaculated sperm with TUNEL-positive proportion >7%, and subsequently underwent microsurgical testicular sperm extraction (TESE). TESE followed by intracytoplasmic sperm injection (ICSI). TUNEL-positive level in ejaculated and testicular sperm; clinical pregnancy. The mean TUNEL-positive level was 24.5% for ejaculated sperm, and 4.6% for testicular sperm. Clinical pregnancy was achieved in the first ART cycle with testicular sperm in 12 (50%) out of 24 couples. There was no statistically significant difference in maternal and paternal age, maternal gravity and parity, number of previous ART attempts, concentration or motility of retrieved sperm, number of oocytes retrieved, fertilization rate, or number of embryos transferred between couples who did and did not achieve pregnancy. No miscarriages occurred. All 12 pregnancies resulted in the delivery of healthy children. The percentage of TUNEL-positive cells is lower in testicular sperm for oligospermic men who have abnormal ejaculated sperm DNA fragmentation. The use of testicular sperm for ICSI was associated with a 50% pregnancy and live-birth rate for couples who had previously failed one or more IVF-ICSI cycles with ejaculated sperm. No other clinical predictors of successful pregnancies after the use of surgically retrieved sperm could be identified. In men with elevated TUNEL-positive ejaculated sperm and failed ART, TESE may be considered.

Antimüllerian hormone: prediction of cumulative live birth in gonadotropin-releasing hormone antagonist treatment for in vitro fertilization

To assess the accuracy of antimüllerian hormone (AMH) in predicting cumulative live birth rate (CLBR) within 1 year after treatment initiation in GnRH antagonist treatment cycles for in vitro fertilization (IVF). Observational (retrospective) substudy as part of an ongoing prospective cohort study. University medical center. A total of 487 patients scheduled for IVF/intracytoplasmic sperm injection (ICSI). Patients starting their first IVF/ICSI cycle with 150 or 225 IU recombinant FSH and GnRH antagonist cotreatment were included. Serum samples collected before the first IVF treatment were used to determine AMH. Treatment data after treatment initiation for a maximum of 1 year were recorded. Prediction of CLBR with the use of AMH. The model for predicting CLBR within 1 year included age at first treatment, AMH, type of infertility, and previous assisted reproductive technology treatment leading to live birth. The accuracy in discriminating between women who did or did not achieve a live birth was only 59%. AMH had intermediate added value in the prediction of CLBR as demonstrated by the net reclassification improvement (total 29.8). A nomogram based on age and AMH was developed by which a subgroup of patients could be identified with the poorest pregnancy prospects. The predictive accuracy of AMH for 1-year CLBR in GnRH antagonist treatment cycles was limited and did not yield much additional value on top of age. Withholding treatment based on predictors such as age and AMH, or a combination, remains problematic. www.clinicaltrials.gov, NCT02309073.
