High prevalence of low prognosis by the POSEIDON criteria in women undergoing planned oocyte cryopreservation

OBJECTIVE

Planned oocyte cryopreservation (OC) is being increasingly utilized worldwide. However, some women cannot accumulate sufficient oocytes because of poor response to stimulation. The POSEIDON classification is a novel system to classify patients with 'expected' or 'unexpected' inappropriate ovarian response to exogenous gonadotropins. Our study aimed to examine the prevalence of POSEIDON patients among women undergoing planned OC.

STUDY DESIGN

We retrospectively reviewed the first cycles of 160 consecutive patients undergoing planned OC. Patients were classified into the four POSEIDON groups or as 'non-POSEIDON' based on age, AMH level and the number of oocytes retrieved. The primary outcome measure was the prevalence of POSEIDON patients.

RESULTS

Overall, 63 patients (39.4 %) were classified as POSEIDON patients, 12 in group 1, 12 in group 2, 8 in group 3, and 31 in group 4. Compared to non-POSEIDON patients, POSEIDON patients had increased basal FSH levels and reduced serum AMH levels and antral follicle counts, required higher FSH starting doses and increased gonadotropin requirements and reached lower peak serum estradiol levels. Additionally, POSEIDON patients had a lower number of oocytes retrieved (7.6 ± 3.1 vs.20.2 ± 9.9, p < 0.001) and vitrified (5.8 ± 2.9 vs.14.7 ± 6.8, p < 0.001) than non-POSEIDON counterparts, respectively.

CONCLUSION

We found a high prevalence of patients being classified as low prognosis according to the POSEIDON criteria among patients seeking planned OC. POSEIDON patients had increased gonadotropin requirements and a significantly lower number of oocytes retrieved and vitrified. This novel, unexpected finding adds clinically relevant information for counselling and management of patients undergoing planned OC.

Placenta previa in in vitro fertilization and unassisted pregnancies-is there a difference in perinatal outcomes and placental histology?

INTRODUCTION

In-vitro-fertilization (IVF) is an independent risk factor for placenta previa (PP). Our aim was to study this link by comparing the clinical characteristics and placental histology of pregnancies complicated by PP in IVF versus unassisted pregnancies.

METHODS

A retrospective-cohort study of deliveries with PP between 2008 and 2021. Placental histology, obstetric and neonatal outcomes were compared between IVF and unassisted pregnancies. Included, were singleton deliveries complicated by PP at gestational weeks (GA) >24.

RESULTS

A total of 182 pregnancies were included - 23 IVF pregnancies (IVF group) and 159 unassisted pregnancies (Control group). The control group was characterized by higher gravidity (p = .007) and parity (p < .001) and a trend of more past cesarean deliveries, whereas the IVF group- by a higher rate of nulliparity (p < .001) and diabetes mellitus (p = .04). The control group was characterized by a higher rate of placental weight below the 10th percentile (47.8 versus 13.9%, p = .001) and by a trend of a lower overall placental weight. No differences were noted in maternal and fetal vascular lesions.

DISCUSSION

While PP in non-assisted pregnancies is probably associated with previous CDs, in IVF it is more "sporadic," and may complicate any index pregnancy. A lower placental weight was more prevalent in the control group, supporting the concept that pregnancies complicated by PP following IVF can be attributed to initial abnormal location of placentation, rather than an underlying pathological uterine segment of implantation. Nevertheless, IVF and unassisted pregnancies entail similar perinatal outcomes in cases of PP.

Obstetric and perinatal outcomes following ovulation induction and unassisted pregnancies in the same mother

OBJECTIVE

We aimed to assess whether ovulation induction treatments affect obstetric and neonatal outcomes.

STUDY DESIGN

This was a historic cohort study of deliveries in a single university-affiliated medical center between November 2008 and January 2020. We included women who had one pregnancy following ovulation induction, and one unassisted pregnancy. The obstetric and perinatal outcomes were compared between pregnancies following ovulation induction and unassisted pregnancies, so that each woman served as her own control. The primary outcome measure was birthweight.

RESULTS

A total of 193 deliveries following ovulation induction and 193 deliveries after unassisted conception by the same women were compared. Ovulation induction pregnancies were characterized by a significantly younger maternal age and a higher rate of nulliparity (62.7% vs. 8.3%, p<0.001). In pregnancies achieved by ovulation induction we found a higher rate of preterm birth (8.3% vs. 4.1%, p=0.02) and instrumental deliveries (8.8% vs. 2.1%, p=0.005), while cesarean delivery rates were higher following unassisted pregnancies. Birthweight was significantly lower in ovulation induction pregnancies (3167 ± 436 vs. 3251 ± 460 grams, p=0.009), although the rate of small for gestational age neonates was similar between the groups. On multivariate analysis, birthweight remained significantly associated with ovulation induction after adjustment for confounders, while preterm birth did not.

CONCLUSION

Pregnancies following ovulation induction treatments are associated with lower birthweight. This may be related to an altered placentation process following uterine exposure to supraphysiological hormonal levels.

Contributors to COVID-19-Related Childbirth Anxiety among Pregnant Women in Two Pandemic Waves

COVID-19 has impacted all levels of daily life for people everywhere, with particularly serious implications for pregnant women. This paper examines the COVID-19-related childbirth anxiety (CCA) of Israeli women in the first two waves of the pandemic. We first present two psychotherapeutic case studies with pregnant women in the two waves. This is followed by an empirical study that compared the contribution of background variables, psychological distress, economic concerns, and personal resources to CCA in two samples, Wave 1, March-April 2020 (n = 403) and Wave 2, September-October 2020 (n = 1401), and two subpopulations, Jewish and Arab women. Findings reveal that CCA was significantly lower in Wave 2 than in Wave 1. Furthermore, poorer health, higher education, being an Arab, later gestational week, at-risk pregnancy, wave, higher psychological distress, greater economic concerns, and lower self-compassion contributed to higher childbirth anxiety. Wave moderated the association between optimism and anxiety. The findings of the empirical study, together with insights from the case studies, provide evidence of a decrease in CCA later in the crisis, and indicate the significance of resources for coping with the psychological implications of the pandemic. Moreover, they suggest the importance of empowering self-reliance techniques, such as self-compassion, which was significantly associated with lower anxiety, above and beyond the background and psychological variables. Clinical Impact Statement: Using both psychotherapeutic cases and empirical findings, this study points to the risk and resilience factors that contributed to pregnant women's COVID-19-related childbirth anxiety (CCA) in the first two waves of the pandemic. The study suggests that CCA was higher in the first wave, as well as among women from a minority group. At the same time, the research shows that resilience resources of optimism and self-compassion contributed to the reduction of anxiety. These findings may guide interventions for the vulnerable group of pregnant women in times of crisis.

Mothers' experience of their daughters' fertility problems and treatments

Fertility treatments are a stressful experience. However, the support provided by meaningful support figures, such as a mother, may contribute positively to the mental health of women with fertility issues. The present study therefore explored the experience of Israeli mothers whose daughters encountered fertility problems and underwent treatment to bring their first child into the world. In a retrospective qualitative study, face-to-face semi-structured interviews were conducted with 16 women aged 49-73. Women in the study had a daughter in a spousal heterosexual relationship who conceived her first child via fertility treatment, and this child was up to 4 years old at the time of the interview. Three main themes emerged: (a) The stressfulness of a daughter's fertility problems and treatments for the mother; (b) The mother's supportive role; and (c) The mother's own need for support. The results suggest that due to the unique nature of the mother-daughter relationship, a daughter's fertility problems and treatments are also stressful for her mother. Nevertheless, mothers can be, and wish to be, an important source of support for their daughters. Empirically, further research to extend this understanding is recommended. Practically, professionals should be aware of the mother's distress and the fact that she is likely to deny her own need for support, and make an effort to relate to the stress of these women and help them to be a more effective resource for their daughters.

Personal growth in early pregnancy: the role of perceived stress and emotion regulation

OBJECTIVE

Coping with the stress aroused by early pregnancy can not only result in distress, but may constitute an opportunity to experience personal growth. Relying on the model of posttraumatic growth, this study examined the contribution of perceived stress and emotion regulation to women's personal growth during the first trimester of pregnancy.

METHOD

A convenience sample of Israeli women (n=170), who were during their first trimester of pregnancy (up to 13 weeks), over 18 years old, and capable to completing the instruments in Hebrew, were recruited through a women's health clinic and through social media during the years 2017-2019.

RESULTS

The findings indicate that primiparous mothers report higher personal growth than multiparous. In addition, younger age, being primiparous, and higher cognitive-reappraisal contributed to greater personal growth. Moreover, a curvilinear association was found between perceived stress and personal growth, so that a medium level of stress was associated with the highest level of growth. Finally, cognitive-reappraisal fully mediated the relationship between perceived stress and personal growth.

CONCLUSIONS

The findings add to the growing body of knowledge concerning the implications of early pregnancy in general, and personal growth as a result of dealing with the stress typical of this period in particular and highlight the role of the perceived stress as well as the woman's personal characteristics and resources that contribute to this result.

The effect of SARS-CoV-2 mRNA vaccination on AMH concentrations in infertile women

RESEARCH QUESTION

Does SARS-CoV-2 mRNA vaccination affect the ovarian reserve of infertile women undergoing IVF?

DESIGN

This was a prospective observational study at a single university-affiliated IVF unit that included infertile women aged 18-44 years who were undergoing IVF/intracytoplasmic sperm injection between November 2020 and September 2021, had received two doses of SARS-CoV-2 mRNA vaccination and had undergone measurement of baseline anti-Müllerian hormone (AMH) concentration within the 12 months preceding their recruitment. AMH concentrations before and after vaccination were evaluated and compared.

RESULTS

Overall, 31 women were included in the study. The median AMH concentrations before and after COVID-19 vaccine were comparable (1.7 versus 1.6 g/ml, respectively, P = 0.96). No correlation was found between the participant's anti-COVID-19 antibody titre and the change in AMH concentration.

CONCLUSIONS

SARS-CoV-2 mRNA vaccination does not adversely affect ovarian reserve, as shown by comparing serum AMH concentrations before and after vaccination. These findings may serve as a counselling tool for clinicians to reassure women undergoing fertility treatment that SARS-CoV-2 mRNA vaccination is safe.

Obstetric outcomes following ovarian hyperstimulation syndrome in IVF - a comparison with uncomplicated fresh and frozen transfer cycles

Background

We aimed to assess the correlation between ovarian hyperstimulation syndrome (OHSS) in the early course of in vitro fertilization (IVF) pregnancies and obstetric outcomes.

Methods

We identified records of patients admitted due to OHSS following IVF treatment at our institution between 2008 and 2020. Cases were included if pregnancy resulted in a live singleton delivery (OHSS group). OHSS cases were matched at a 1:5:5 ratio with live singleton deliveries following IVF with fresh embryo transfer (fresh transfer group) and frozen embryo transfer (FET group), according to maternal age and parity. Computerized files were reviewed, and maternal, obstetric and neonatal outcomes compared.

Results

Overall, 44 OHSS cases were matched with 220 fresh transfer and 220 FET pregnancies. Patient demographics were similar between the groups, including body mass index, smoking and comorbidities. Gestational age at delivery, the rate of preterm births, preeclampsia and cesarean delivery were similar between the groups. Placental abruption occurred in 6.8% of OHSS pregnancies, 1.4% of fresh transfer pregnancies and 0.9% of FET pregnancies (p=0.02). On post-hoc analysis, the rate of placental abruption was significantly higher in OHSS pregnancies, compared with the two other groups, and this maintained significance after adjustment for confounders. Birthweights were 3017 ± 483, 3057 ± 545 and 3213 ± 542 grams in the OHSS, fresh transfer and FET groups, respectively (p=0.004), although the rate of small for gestational age neonates was similar between the groups.

Conclusions

OHSS in the early course of IVF pregnancies is associated with an increased risk of placental abruption.

P-353 Placenta previa in In Vitro Fertilization and unassisted pregnancies – is there a difference in perinatal outcomes and placental histology?

Study question

Why is In-vitro-fertilization (IVF) an independent risk factor for placenta previa (PP).

Summary answer

While PP in non-assisted pregnancies is probably associated with previous cesarean deliveries (CD), in IVF it is more “sporadic”, and may complicate any index pregnancy.

What is known already

PP is more prevalent following IVF pregnancies as compared with unassisted pregnancies, with an increased risk of three to six-fold according to some authors. The etiology for this increased risk in IVF pregnancies in unclear, and may be related to reproductive procedures performed or to subfertility characteristics which have led to IVF.

Study design, size, duration

A retrospective-cohort study of deliveries with PP between 2008 and 2021. A total of 182 pregnancies were included.

Participants/materials, setting, methods

Placental histopathology, obstetric and neonatal outcomes were compared between IVF and unassisted pregnancies. Included, were singleton deliveries complicated by PP at gestational weeks (GA)&gt; 24. Placental pathology was obtained utilizing the well-accepted Amsterdam criteria.

Main results and the role of chance

Out of 182 pregnancies which were included - 23 IVF pregnancies (IVF group) and 159 in the unassisted pregnancies (Control group). The control group was characterized by higher gravidity (p = 0.007) and parity (p &lt; 0.001), whereas the IVF group- by a higher rate of nulliparity (p &lt; 0.001) and diabetes mellitus (p = 0.04). A higher rate of patients with past CDs was noted in unassisted pregnancies, although not statistically significance (38.9% versus 21.7%, p = 0.10). There was a trend for a lower placental weight in the control group, and a higher incidence of placental weight below the 10thpercentile in this group (47.8% versus 13.9%, p = 0.001). No differences were noted in maternal and fetal vascular lesions. Nevertheless, IVF and unassisted pregnancies entail similar perinatal outcomes in cases of PP.

Limitations, reasons for caution

A major limitation was our small sample size in the IVF group. Despite a power calculation, larger study groups would have possibly allowed for the demonstration of additional differences in outcomes, including previous cesarean deliveries and placenta accreta. Moreover, this limitation prevented us from matching against possible cofounders.

Wider implications of the findings

While a growing proportion of pregnancies worldwide are conceived by IVF, possible iatrogenic side effects should be studied. As PP is of clinical importance, it is essential to diagnose it on time, as well as study the mechanisms and risk factors behind it, which could possibly help with its prevention.

Prediction, assessment, and management of suboptimal GnRH agonist trigger: a systematic review

PURPOSE

This systematic review aimed to identify baseline patient demographic and controlled ovarian stimulation characteristics associated with a suboptimal response to GnRHa triggering, and available options for prevention and management of suboptimal response.

METHODS

PubMed, Google Scholar, Medline, and the Cochrane Library were searched for keywords related to GnRHa triggering, and peer-reviewed articles from January 2000 to September 2021 included.

RESULTS

Thirty-seven studies were included in the review. A suboptimal response to GnRHa triggering was more likely following long-term or recent oral contraceptive use and with a low or high body mass index. Low basal serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol serum levels were correlated with suboptimal oocyte yield, as was a low serum LH level on the day of triggering. A prolonged stimulation period and increased gonadotropin requirements were correlated with suboptimal response to triggering. Post-trigger LH < 15 IU/L best correlated with an increased risk for empty follicle syndrome and a lower oocyte retrieval rate. Retriggering with hCG may be considered in patients with suboptimal response according to post-trigger LH, as in cases of failed aspiration.

CONCLUSION

Pre-treatment assessment of patient characteristics, with pre- and post-triggering assessment of clinical and endocrine cycle characteristics, may identify cases at risk for suboptimal response to GnRHa triggering and optimize its utilization.

Gestational diabetes mellitus in in-vitro fertilization pregnancies - Clinical and placental histological characteristics

INTRODUCTION

We aimed to investigate obstetric and neonatal outcomes and placental histological findings in in vitro fertilization (IVF) pregnancies complicated by gestational diabetes mellitus (GDM) as compared to unassisted pregnancies.

METHODS

This was a retrospective cohort of deliveries at a single university affiliated center between 12/2008 and 01/2020. Included were singleton pregnancies complicated by GDM, for which placental histopathological examination was performed. Obstetric, neonatal and placental outcomes were compared between pregnancies following IVF and unassisted pregnancies. Placental lesions were categorized according to the "Amsterdam" criteria.

RESULTS

Included were 688 deliveries with a diagnosis of GDM with placental examination - 69 IVF pregnancies (IVF group) and 619 unassisted pregnancies (control group). The IVF group was characterized by a significantly higher maternal age and higher rate of nulliparous women - 60.8% vs. 32.9%, p < 0.001. There were no differences in GDM type between the study groups - about two thirds of cases were GDMA1 and on third GDMA2. A higher incidence of preeclampsia was noted in the IVF group - 17.3% vs. 9.3%, p = 0.03, with no difference in cesarean deliveries and birthweight. IVF deliveries were characterized by a significantly higher rate of adverse neonatal outcomes - 18.8% vs. 8.8%, p = 0.008, although this did not attain significance after adjustment to gestational age. No differences were noted in placental histology between the groups.

DISCUSSION

GDM in IVF is associated with a significantly higher rate of adverse neonatal outcomes, as compared with non-assisted pregnancies complicated by GDM. Placental histology does not shed light on these clinical associations.

A randomized controlled trial of vaginal progesterone for luteal phase support in modified natural cycle - frozen embryo transfer

OBJECTIVE

Our aim was to study whether luteal phase support (LPS) increases the live-birth rate (LBR) in women undergoing modified natural cycle (mNC) frozen-thawed embryo transfer (FET).

METHODS

In a randomized controlled trial, conducted at a university-affiliated tertiary medical center, a total of 59 patients aged 18-45 years, underwent mNC-FET. FET was performed in mNC following ovulation triggering by hCG. Patients were randomized into two groups; The No-LPS Group included 28 women who did not receive LPS, and the LPS Group included 31 women who received vaginal progesterone for LPS. The main outcome measure was LBR.

RESULTS

Baseline demographic and clinical characteristics were comparable between the study groups. The no-LPS group and the LPS group did not differ with regard to clinical pregnancy rate (21.4% vs. 32.3%; respectively, p = .35), LBR (17.9% vs. 19.4%; respectively, p = .88), or spontaneous miscarriage rate (3.6% vs. 12.9%; respectively, p = .35). On multivariate logistic regression analysis, LPS was not associated with LBR after controlling for confounders.

CONCLUSION

The results of our study suggest that LPS after mNC-FET does not improve the reproductive outcome, and therefore, might not be necessary.C linicaltrials.gov identifier: NCT01483365.

P–649 Should women receive luteal support following natural cycle frozen embryo transfer? A systematic review and meta-analysis

Study question

Should women receive luteal phase support (LPS) following natural cycle frozen embryo transfer (NC-FET)?

Summary answer

Progesterone LPS following NC-FET increases the live birth rate. There is no evidence to support the administration of hCG for LPS in these cases.

What is known already

Whether or not women should receive LPS following NC-FET is highly controversial. Previous studies have shown conflicting results.

Study design, size, duration

We conducted a systematic search of the literature published in Medline/PubMed, Embase and the Cochrane Library, from January 2000 until December 2020. We included all original English, peer-reviewed articles, irrespective of study-design. The search strategy included keywords related to natural cycle frozen embryo transfer and luteal phase support. Studies reporting the results of artificial or stimulated FET cycles were excluded.

Participants/materials, setting, methods

Our systematic search generated 395 records. After screening, eight studies were included in the review and seven studies were included in the meta-analysis. Two studies (n = 858) used hCG, and 6 studies (n = 1507) used progesterone for luteal support. Four studies were randomized controlled trials (RCTs), whereas the other four were historic cohort studies.

Main results and the role of chance

In a meta-analysis using random effects model, hCG administration for LPS did not increase the clinical pregnancy rate (two studies, OR 0.85, 95% CI 0.64–1.14). On the other hand, progesterone LPS was associated with a higher clinical pregnancy rate (five studies, OR 1.48, 95% CI 1.14–1.94), and a higher live birth rate (three studies, OR 1.67, 95% CI 1.19–2.36).

Limitations, reasons for caution

There was large heterogeneity in progesterone dose and route of administration, as well as the methods used for ovulation detection and triggering. Moreover, only four studies were randomized. Finally, both studies examining the use of hCG for LPS were performed by the same group of researchers in a single center.

Wider implications of the findings: The available evidence indicates that progesterone administration for LPS is beneficial following natural cycle frozen embryo transfer. There is no evidence to support the administration of hCG for LPS in these cases. Additional Large RCTs are necessary in order to improve the quality of evidence and validate our findings.

Should women receive luteal support following natural cycle frozen embryo transfer? A systematic review and meta-analysis

BACKGROUND

Spontaneous ovulation during a natural menstrual cycle is frequently used for timing frozen embryo transfer (FET). Nevertheless, it remains unclear whether or not women should receive luteal phase support (LPS) following natural cycle frozen embryo transfer (NC-FET).

OBJECTIVE AND RATIONALE

The aim of this systematic review and meta-analysis was to study whether the administration of LPS improves the reproductive outcome following NC-FET.

SEARCH METHODS

We conducted a systematic search of the literature published in Medline/PubMed, Embase and the Cochrane Library, from January 2000 until December 2020. We included all original English, peer-reviewed articles, irrespective of the study design. The search strategy included keywords related to NC-FET and luteal phase support. Studies reporting the results of artificial or stimulated FET cycles were excluded.

OUTCOMES

Our systematic search generated 416 records. After screening, eight studies were included in the review and seven studies were included in the meta-analysis. Two studies (n = 858) used hCG and six studies (n = 1507) used progesterone for luteal support. Four studies were randomised controlled trials (RCTs), whereas the other four were historic cohort studies. In a meta-analysis using a random effects model, hCG administration for LPS did not increase the clinical pregnancy rate (CPR) (two studies, odds ratio (OR) 0.85, 95% CI 0.64-1.14). On the other hand, progesterone LPS was associated with a higher CPR (five studies, OR 1.48, 95% CI 1.14-1.94), and a higher live birth rate (LBR) (three studies, OR 1.67, 95% CI 1.19-2.36). The association between progesterone LPS and the LBR remained significant after excluding non-randomised studies.

WIDER IMPLICATIONS

The available evidence indicates that progesterone administration for LPS is beneficial following NC-FET. There is no evidence to support the administration of hCG for LPS in these cases. Additional large RCTs are necessary to improve the quality of evidence and validate our findings.

Misoprostol treatment for early pregnancy loss: an international survey

RESEARCH QUESTION

What is the global variability in misoprostol treatment for the management of early pregnancy loss (EPL)?

DESIGN

An international web-based survey of fertility specialists and obstetrics and gynaecology clinicians was conducted between August and November 2020. The survey consisted of 16 questions addressing several aspects of misoprostol treatment for EPL.

RESULTS

Overall, 309 clinicians from 80 countries participated in the survey, of whom 67.3% were fertility specialists. Nearly one-half (47.9%) of the respondents let the patient choose the first line of treatment (expectant management, misoprostol treatment or surgical aspiration) according to her own preference. The 248 respondents who administer misoprostol in their daily practice were asked further questions; 59.7% of them advise patients to take the medication at home. The most common dose and route of administration is 800 µg administered vaginally. Only 28.6% of participants use mifepristone pretreatment. Variation in the timing of the first follow-up visit after misoprostol administration was wide, ranging from 24 h to 1 week in most clinics. In case of incomplete expulsion, only 42.3% of the respondents routinely administer a second dose. The timing of the final visit and the definition of successful treatment also differed greatly among respondents.

CONCLUSIONS

There is large variability in the use of misoprostol for the management of EPL. High-quality research is necessary to examine several aspects of the treatment. Particularly, the timing and effectiveness of a second dose administration and the criteria to decide on treatment failure or success deserve more research in the future.

The stair-step approach in treatment of anovulatory PCOS patients

Clomiphene citrate (CC) is a widely accepted first-line treatment for anovulatory patients with polycystic ovarian syndrome (PCOS). The current practice is to prescribe CC with gradual dose increments until ovulation is achieved. Typically, progesterone withdrawal bleeding is induced between each dose increment and before the commencement of gonadotropin therapy in CC-resistant patients. It has been recently suggested that dose increments of CC can be administered once failure to induce ovulation at a certain dose has been documented, without induction of progesterone withdrawal bleeding, and this approach has been nicknamed the clomiphene-citrate stair-step (CC-SS) protocol. The same principle has been found feasible before introducing gonadotropin therapy in CC-resistant PCOS patients. Our objective was to review the world literature on the CC-SS protocol and to summarize our own experience with extending the CC-SS approach to initiation of gonadotropin therapy. Studies on CC-SS protocol (n = 4) have found that this approach leads to a significant reduction of the time to ovulation and to an increased ovulation rate. In our own retrospective case series, 18 CC-resistant PCOS patients initiated gonadotropin stimulation without induction of progesterone withdrawal bleeding, using the chronic low-dose regimen. The time to ovulation in the study group was 54.2 ± 6.2 days, while the estimated time to ovulation calculated according to the traditional approach was approximately 110 days. The clinical pregnancy rate was 44% (8/18), and all pregnancies were singletons. One patient miscarried; hence, the live birth rate was 38.9% (7/18). In summary, the CC-SS approach and its extension to the initiation of gonadotropin therapy results in considerable reduction of the time to ovulation, and favorable ovulation rates and reproductive outcome. Large-scale confirmation of these findings by properly designed randomized controlled trials may lead to a change of practice in the treatment of anovulatory infertility in PCOS patients, allowing simplification of treatment and a shorter time to ovulation and pregnancy.

Placental histopathology in IVF pregnancies resulting from the transfer of frozen-thawed embryos compared with fresh embryos

PURPOSE

To study whether placentas of singleton pregnancies conceived after fresh embryo transfer (ET) contain more histopathological lesions compared with placentas of singleton pregnancies conceived after frozen-thawed embryo transfer (FET).

METHODS

A prospective cohort study of placental histopathology in 131 women with singleton IVF pregnancies who delivered at a single medical center, between December 2017 and May 2019. The prevalence of different placental histopathology lesions was compared between women who conceived after fresh ET and FET.

RESULTS

Women who conceived after fresh ET (n = 74) did not differ from women who conceived after FET (n = 57) with regard to maternal age, BMI, nulliparity, or infertility diagnosis. Gestational week at delivery was lower in pregnancies conceived after fresh ET (38.5 vs. 39.2 weeks, respectively, p = 0.04), and a trend for a lower birthweight following fresh ET was noted (3040 vs. 3216 g, respectively, p = 0.053). However, placental histopathology analysis from pregnancies conceived after fresh ET was comparable to pregnancies conceived after FET, with regard to the prevalence of maternal vascular malperfusion lesions (45.9% vs. 50.9%, respectively, p = 0.57), fetal vascular malperfusion lesions (17.6% vs. 21.1, p = 0.61), acute inflammatory response lesions (28.4% vs. 28.1%, respectively, p = 0.96), and chronic inflammatory response lesions (13.5% vs. 8.8%, respectively, p = 0.48).

CONCLUSION

Placental histopathology did not differ between IVF pregnancies conceived after fresh and frozen ET. These results are reassuring for clinicians and patients who wish to pursue with transferring fresh embryos.

Ovarian stimulation for freeze-all IVF cycles: a systematic review

BACKGROUND

Freeze-all IVF cycles are becoming increasingly prevalent for a variety of clinical indications. However, the actual treatment objectives and preferred treatment regimens for freeze-all cycles have not been clearly established.

OBJECTIVE AND RATIONALE

We aimed to conduct a systematic review of all aspects of ovarian stimulation for freeze-all cycles.

SEARCH METHODS

A comprehensive search in Medline, Embase and The Cochrane Library was performed. The search strategy included keywords related to freeze-all, cycle segmentation, cumulative live birth rate, preimplantation genetic diagnosis, preimplantation genetic testing for aneuploidy, fertility preservation, oocyte donation and frozen-thawed embryo transfer. We included relevant studies published in English from 2000 to 2018.

OUTCOMES

Our search generated 3292 records. Overall, 69 articles were included in the final review. Good-quality evidence indicates that in freeze-all cycles the cumulative live birth rate increases as the number of oocytes retrieved increases. Although the risk of severe ovarian hyperstimulation syndrome (OHSS) is virtually eliminated in freeze-all cycles, there are certain risks associated with retrieval of large oocyte cohorts. Therefore, ovarian stimulation should be planned to yield between 15 and 20 oocytes. The early follicular phase is currently the preferred starting point for ovarian stimulation, although luteal phase stimulation can be used if necessary. The improved safety associated with the GnRH antagonist regimen makes it the regimen of choice for ovarian stimulation in freeze-all cycles. Ovulation triggering with a GnRH agonist almost completely eliminates the risk of OHSS without affecting oocyte and embryo quality and is therefore the trigger of choice. The addition of low-dose hCG in a dual trigger has been suggested to improve oocyte and embryo quality, but further research in freeze-all cycles is required. Moderate-quality evidence indicates that in freeze-all cycles, a moderate delay of 2–3 days in ovulation triggering may result in the retrieval of an increased number of mature oocytes without impairing the pregnancy rate. There are no high-quality studies evaluating the effects of sustained supraphysiological estradiol (E2) levels on the safety and efficacy of freeze-all cycles. However, no significant adverse effects have been described. There is conflicting evidence regarding the effect of late follicular progesterone elevation in freeze-all cycles.

WIDER IMPLICATIONS

Ovarian stimulation for freeze-all cycles is different in many aspects from conventional stimulation for fresh IVF cycles. Optimisation of ovarian stimulation for freeze-all cycles should result in enhanced treatment safety along with improved cumulative live birth rates and should become the focus of future studies.

Modified natural-cycle cryopreserved embryo transfer: is a washout period needed after a failed fresh cycle?

RESEARCH QUESTION

Are the characteristics of the natural cycle or modified natural cycle (mNC), or live birth rates (LBR), affected by delaying frozen embryo transfer (FET) after a failed fresh IVF cycle?

DESIGN

In a retrospective study, conducted at a university-affiliated tertiary centre, 198 women aged 18-45 years undergoing their first FET cycle after a failed fresh embryo transfer attempt using an mNC were evaluated. Cycles were divided according to the time interval between oocyte retrieval and the start of the FET cycle into the immediate FET group (<22 days) and the delayed FET group (≥22 days). The main outcome measures were ovulation day and LBR.

RESULTS

The mean interval between oocyte retrieval and the start of the FET cycle was 15.6 ± 3.2 days in the immediate FET group and 84.8 ± 73.7 days in the delayed FET group (P < 0.001). Ovulation day was significantly delayed in the immediate FET group (day 17.1 ± 4.4 versus day 15.4 ± 3.7; P = 0.004). There was no difference between the immediate and delayed FET groups in terms of clinical pregnancy rate (CPR) (25.4% and 25.0%, respectively) or LBR (21.2% and 20.0%, respectively).

CONCLUSIONS

Natural-cycle characteristics are similar in immediate and delayed cycles, except for a slight delay in ovulation day. Deferring mNC-FET after a failed fresh IVF cycle does not improve the reproductive outcome. These results should encourage patients and clinicians who want to proceed with FET immediately after failure of fresh IVF.

Contributors to Women's Perceived Stress at the Start of Assisted Reproductive Technology

Clinicians are often called upon to treat the stress that accompanies Assisted Reproductive Technology (ART). In this study, we sought to examine the contribution of the internal resources of meaning in life and attachment style and the interpersonal resource of self-disclosure to her mother to a woman's level of perceived stress upon commencement of ART. In addition, we examined the association between age and perceived stress. The sample consisted of 180 Israeli women (106 aged 20-34; 74 aged 35-44) who completed a series of self-report questionnaires after their initial meeting with a fertility specialist. Regression analysis indicated that older age, lower attachment anxiety, higher perception of meaning in life, and greater self-disclosure to the mother were related to lower levels of perceived stress. Self-disclosure was also found to mediate the association between avoidant attachment and stress. The study highlights the importance of a woman's personal and interpersonal resources for reducing the experience of stress in the early stages of ART. The results have practical implications for the development of professional interventions seeking to enhance these resources among women embarking on fertility treatment.

Cumulative pregnancy and live birth rates through assisted reproduction in women 44-45 years of age: is there any hope?

PURPOSE

The purpose of the study is to calculate the cumulative pregnancy rate and cumulative live birth rate in women undergoing in vitro fertilization (IVF) at ages 44-45.

METHODS

The study calculated cumulative live pregnancy rate and cumulative live birth rate of 124 women aged 44 to 45 years old who commenced IVF treatment.

MAIN OUTCOME MEASURES

The main outcome measures are cumulative live pregnancy rate and cumulative live birth rate.

RESULTS

Cumulative live pregnancy rates following 1, 2, 3, and 4 cycles were 5.6, 11, 17, and 20%, respectively, with no additional pregnancies in further cycles. Cumulative live birth rates following 1, 2, and 3 cycles were 1.6, 3, and 7%, respectively, with no additional live births in further cycles.

CONCLUSIONS

The cumulative pregnancy rate rises during the first 4 cycles and cumulative live birth rate rises during the first 3 cycles, with no additional rise in pregnancies or deliveries thereafter, suggesting that it is futile to offer more than 3 cycles of treatment to 44-45-year-old women.

Extension of the clomiphene citrate stair-step protocol to gonadotropin treatment in women with clomiphene resistant polycystic ovarian syndrome

Our objective was to evaluate the safety and efficacy of direct initiation of gonadotropin ovarian stimulation without prior withdrawal bleeding in anovulatory clomiphene citrate (CC) resistant polycystic ovarian syndrome (PCOS) patients. Eighteen PCOS patients underwent ovulation induction with CC using a stair-step regimen. Patients who failed to respond to the maximal dose of CC initiated gonadotropin stimulation without inducing withdrawal bleeding, using the chronic low dose regimen. The primary outcome measure was the time to ovulation from the beginning of CC treatment until the day of ovulatory trigger. This was compared with the time to ovulation calculated according to the traditional approach, which includes inducing progesterone withdrawal bleeding between each CC dose increment and before gonadotropin therapy. The time to ovulation in the study group was 67.0 ± 6.8 days. The estimated time to ovulation according to the traditional approach was approximately 110 days. The clinical pregnancy rate was 44% (8/18), and all pregnancies were singletons. One patient miscarried; hence the live birth rate was 38.9% (7/18). Direct initiation of gonadotropin therapy without prior induction of withdrawal bleeding in clomiphene resistant PCOS patients results in considerable reduction of the time to ovulation and is both safe and efficacious.

Mental health of women entering fertility treatment: What role do age and internal resources play?

Drawing on Lazarus and Folkman's (1984) model of stress and coping, the study aimed at (a) examining the associations between the mental health of women entering fertility treatment and their internal resources (hope and two aspects of self-consciousness: reflection and rumination); (b) indicating whether mental health is associated with age (above or below 35), and whether this association is mediated by the internal resources. The sample consisted of 137 women (76 aged 20-34; 61 aged 35-44) at the start of fertility treatment who completed a series of self-report questionnaires. Results indicated that younger women reported higher distress and rumination than older women. Higher hope was associated with greater well-being, and higher rumination was associated with greater distress. Furthermore, hope and rumination were found to mediate the association between age and mental health. These findings highlight the importance of developing age-based interventions for women entering fertility treatment, aimed at strengthening their resilience to effectively cope with the demanding process ahead.

Satisfaction in life among fathers following fertility treatment

OBJECTIVE

The study aimed at (a) gaining a better understanding of how fertility history (ART/spontaneous) is associated with life satisfaction among new fathers; and (b) identifying personal and interpersonal risk factors for lower satisfaction in life during the transition to fatherhood.

DESIGN

This cross-sectional study comprised 172 Israeli fathers (76 who became fathers following ART and 96 following spontaneous pregnancy), who completed a series of self-report questionnaires 5-18 months after the birth of their first child.

RESULTS

No differences were found in life satisfaction between fathers in the two fertility history groups. Regression analysis indicated that younger age and higher economic status, as well as lower attachment anxiety and avoidance and better marital relationship, were associated with a higher level of life satisfaction among new fathers.

CONCLUSION

Although the life satisfaction of new fathers does not appear to be affected by their fertility history, it may be hampered by personal and interpersonal risk factors. These results have practical implications for professionals who come into contact with this population.

Endometrial nerve fibre density in patients undergoing IVF: a pilot study

The presence of nerve fibres in the functional layer of the endometrium has been strongly associated with endometriosis. Presence of nerve fibres in the endometrium of women undergoing IVF has not been previously assessed. This prospective pilot study assessed the presence of nerve fibres in endometrium of women undergoing IVF due to various causes and examined the correlation between the presence of nerve fibres and IVF success. A total of 32 IVF patients underwent endometrial biopsy during days 21-23 of the menstrual cycle. Nerve fibres were identified by immunohistochemical staining. Correlations between the presence and density of nerve fibres and aetiology of infertility and IVF success were measured. Nerve fibres were identified in the endometrium of 10/31 (32.3%) women with a satisfactory biopsy. Presence of nerve fibres was not correlated with cause of infertility. Clinical pregnancy was achieved in 12/32 (37.5%) patients, without correlation to presence of nerve fibres in the endometrium. Nerve fibres were identified in a substantial percentage of women undergoing IVF, possibly reflecting underdiagnosis of endometriosis in this population. The presence of nerve fibres does not appear to interfere with implantation. The significance of nerve fibres in the endometrium of IVF patients warrants further research.

Dehydroepiandrosterone supplementation increases baseline follicular phase progesterone levels

The use of dehydroepiandrosterone (DHEA) supplementation in infertile patients with diminished ovarian reserve (DOR) has become increasingly popular. It has been our observation that serum progesterone levels during the follicular phase are often increased during controlled ovarian stimulation when DHEA is coadministered. Our aim was to compare progesterone levels during the follicular phase before and during DHEA supplementation in women with DOR undergoing in vitro fertilization (IVF). In a case-control study, we compared progesterone levels during the follicular phase in IVF cycles before and during DHEA supplementation in 15 women with DOR who received 75 mg of DHEA daily. Progesterone levels on stimulation day 5 (0.5 ± 0.29 ng/ml vs. 1.54 ± 0.49 ng/ml; p < 0.0001) and on the day of human chorionic gonadotropin administration (0.75 ± 0.31 ng/ml vs. 1.87 ± 0.49 ng/ml; p < 0.0001) were significantly higher during DHEA treatment. The number of retrieved and fertilized oocytes was similar in both the groups. DHEA administration during IVF cycles in women with DOR causes a significant elevation of progesterone levels without an apparent deleterious effect on cycle outcome.

Routine hemoglobin testing following an elective Cesarean section: is it necessary?

OBJECTIVE

To determine the clinical relevance of routine hemoglobin testing following an elective Cesarean section.

METHODS

The charts of all women who underwent elective Cesarean section at a public teaching hospital during 2001 were reviewed for pre- and postoperative hemoglobin values, demographic data, indication for surgery and need for blood transfusion.

RESULTS

The study group included 383 patients. Mean (+/- SD) hemoglobin level was 12.24 +/- 1.09 g/dl prior to surgery and 10.87 +/- 1.2 g/dl after, a mean loss of 1.37 +/- 0.87 g/dl (p < 0.001). There was no significant difference in blood loss by indication for surgery. None of the patients needed an intraoperative or postoperative blood transfusion.

CONCLUSION

Routine postoperative hemoglobin measurement after an uncomplicated elective Cesarean section in asymptomatic low-risk women is not necessary and should be eliminated.

Pregnancies and live births following ICSI with testicular spermatozoa after repeated implantation failure using ejaculated spermatozoa

The use of testicular spermatozoa for IVF/intracytoplasmic sperm injection (ICSI) is currently indicated exclusively for patients with azoospermia, since a favourable outcome is expected even when very few spermatozoa are present in the ejaculate. Here, a series of four couples with long-standing male factor infertility and multiple failed IVF/ICSI cycles are described. In all couples, the use of ejaculated spermatozoa for ICSI resulted in poor embryo quality and repeated implantation failure. Testicular sperm aspiration was performed in subsequent cycles, and testicular spermatozoa were used for ICSI. Embryo implantation and ongoing pregnancies/deliveries were achieved in all four couples. It is postulated that spermatozoa are subjected to post-testicular damage during sperm transport between the seminiferous tubules and epididymis, with the injection of damaged spermatozoa being the cause for repetitive IVF/ICSI failures. In selected patients, the use of testicular spermatozoa for IVF/ICSI should be considered, even when motile spermatozoa can be identified in the ejaculate.

Combined intrauterine and twin cervical pregnancy managed by a new conservative modality

OBJECTIVE

To describe a rare case of a heterotopic pregnancy with two gestational sacs in the cervix and one in the uterine cavity.

DESIGN

Case report.

SETTING

Tertiary university hospital.

PATIENT(S)

A 45-year-old woman was diagnosed with a triplet gestation 7 weeks following IVF treatment for primary infertility of 5 years' duration. Transvaginal ultrasound scan revealed three gestational sacs: one sac inside the uterine cavity containing a live fetus, and two sacs in the uterine cervix, one containing a live fetus and a second empty sac.

INTERVENTION(S)

Pregnancy termination was performed by selective intraarterial catheterization of the uterine artery, intraarterial administration of methotrexate, and uterine artery embolization with Gelfoam.

MAIN OUTCOME MEASURE(S)

Intra- or postprocedural complications and fertility preservation.

RESULT(S)

The pregnancy termination was successfully performed without intra- or postprocedural complications, with preservation of the patient's fertility.

CONCLUSION(S)

Intraarterial methotrexate with uterine vessel embolization is an effective conservative approach to heterotopic cervical pregnancy.

[The evolution of midwifery]

Midwifery is an old profession, derived from the nature of human birth, which mandates assistance, in order to protect the parturient and her newborn. During the course of history, midwifery has been typically a feminine occupation, traditionally passed down in the family and involved intimate social relations between the midwife and her patients. Early attempts of teaching and learning of midwifery began at the end of the medieval period, and increased during the 18th and 19th centuries. Only during the last century, such actions were initiated on a national scale and were due to competition from the evolving trade of obstetrics in medicine. When examining the evolution of midwifery in developed-versus developing-countries, it seems that the professional scope and trust given to midwives depends on the availability of medical services (physicians and institutes) in a given state. The history of midwifery demonstrates that midwives' authorities depend on the availability of physicians'-operated obstetric services.

Vulvar hematoma after cunnilingus in a teenager with essential thrombocythemia: a case report

BACKGROUND

Nonobstetric injuries of the female genital tract constitute up to 0.8% of all gynecologic admissions. Approximately 40% of such admissions are due to coital injuries. Vulvar injuries following cunnilingus have been reported only rarely.

CASE

A 17-year-old with known essential thrombocytopenia was being treated with low-dose aspirin and presented with a 4-cm vulvar hematoma that occurred during cunnilingus. The hematoma was evacuated uneventfully, with no signs of further bleeding and no patient complaints. As the patient, a minor under Israeli law, wished to conceal the circumstances from her parents, we told them that she had suffered vulvar trauma from the background disease.

CONCLUSION

This case demonstrates an unexpected complication of a necessary treatment for a major disease and the sometimes dual obligation of physicians to their patients and their families.

[G-spot and female ejaculation: fiction or reality?]

The G-spot is an ill-defined region, located on the anterior vaginal wall, in its upper outer third, suggested by Ernst Grafenberg, and commemorates the first letter of his name. This area is sensitive to tactile touch, which, when applied, is claimed to result in an intense female orgasm. The G-spot is thought to be the vaginal part that lies beneath the posterior part of the "female prostatic gland", which, when stimulated, results in female ejaculation during orgasm. G-spot and female ejaculation have been studied intensively during the last 50 years and there is scientific (anatomical and biochemical) evidence for their existence. However, this evidence has been challenged, and the debate regarding the existence of the G-spot and female ejaculation as true clinical entities is still ongoing.

[The reviewers' review]

Peer review is a process designed to ensure quality, integrity and novelty of scientific or medical studies, published in scientific journals. This process accompanies scientific publication since it began and is the cornerstone of scientific appreciation and acceptance. Since peer review is a non-transparent process and lacks standardized criteria for evaluation, it thereby attracts extensive criticism, as discussed in this article. Editors and reviewers of this journal have a special responsibility when discussing a submitted article, since this journal is the only scientific-medical platform in the Hebrew language.

Hysteroscopy combined with hysterosalpingo contrast sonography (HyCoSy): a new modality for comprehensive evaluation of the female pelvic organs

AIM

Hysterolaparoscopy is the gold-standard procedure for mechanical evaluation of the female pelvic organs. However, it is invasive and potentially life-threatening. The purpose of the present study was to assess the value of an alternative, minimally invasive technique.

METHOD

All consenting women who reached the stage of mechanical evaluation in their infertility work-up were invited to participate in the study. All underwent diagnostic hysteroscopy followed by hysterosalpingo contrast sonography (HyCoSy) performed in a single session on an outpatient basis. Patient clinical data were collected prospectively.

RESULTS

Twenty women participated in the study, 6 with primary infertility and 14 with secondary infertility. All procedures yielded satisfactory evaluation of the uterine cavity and uterine and ovarian structures, fallopian tube patency, and relationship between the fallopian tube fimbrial edges and the ovaries. All patients were discharged within 2 h; there were no complications during or after the procedure.

CONCLUSION

The combination of hysteroscopy and hysterosalpingo contrast sonography (HyCoSy) can provide a comprehensive, functional and relatively non-invasive evaluation of the female pelvic organs.

Ultrasound diagnosis of fourth branchial arch sinus at 22 weeks' gestation

Fourth branchial arch sinus is the rarest of the branchial cleft anomalies and its prenatal detection has not previously been reported in the English literature. We describe a case of fourth branchial arch sinus identified in a fetus during a routine ultrasound evaluation at 22 weeks' gestation. Survey of the fetal anatomy revealed a small 'nipple-like' structure on the neck, arising anteriorly to the sternocleidomastoid muscle, midway between the chin and the left shoulder. The structure persisted unchanged throughout the pregnancy. The prenatal diagnosis of fourth branchial arch sinus was confirmed at delivery at term.

[Genital piercing]

Piercing is defined as puncturing an organ in order to place a jewel in the perforated site. There is almost no external organ in the human body that has escaped piercing. The origin of piercing traces back to the dawn of human history. Piercing is performed for decorative or symbolic purposes. Genital piercing (male or female) has recently extended into Western societies in general and to Israel in particular. The aim of genital piercing is said to be both decorative and for the enhancement of sexual pleasure. There are several types of genital piercing. The procedure is performed by non-medical persons, not within medical institutions, and may involve severe complications. Israeli legislation that regulates genital piercing is lacking.
