Assisted reproduction policies in Israel: a retrospective analysis of in vitro fertilization-embryo transfer

Impact of the number of previous embryo implantation failures on IVF/ICSI-ET pregnancy outcomes in patients younger than 40 years: a retrospective cohort study

Objective

The objective of this study was to examine the influence of repeated embryo implantation failures on pregnancy outcomes among patients under 40 years of age undergoing in vitro fertilization/intracytoplasmic sperm injection embryo transfer (IVF/ICSI-ET).

Materials and methods

A retrospective analysis was conducted on the clinical data of 13,172 patients who underwent 16,975 IVF/ICSI-ET treatment cycles at Henan Reproductive Hospital between January 1, 2015, and December 31, 2018. Patients were categorized into four groups based on the number of previous embryo implantation failure cycles: Group A=no implantation failure, Group B= 1 implantation failure, Group C=2 implantation failures, Group D=≥3 implantation failures. Baseline characteristics and pregnancy outcomes were compared among the four groups. The impact of the number of previous embryo implantation failures on pregnancy outcomes among IVF/ICSI-ET patients was investigated using univariate and multiple regression analyses.

Results

Univariate logistic regression analysis demonstrated that factors such as the number of previous embryo implantation failures, female age, basal follicle count, endometrial thickness, total number of oocytes retrieved, type of cycle, number of high-quality embryos transferred, and stage of embryo development significantly affected implantation rate, clinical pregnancy rate, early spontaneous abortion rate, and live birth rate (all P < 0.05). The duration of infertility and anti-Mullerian hormone (AMH) levels were also found to influence implantation rate, clinical pregnancy rate, and live birth rate (all P < 0.05). Upon conducting multivariate logistic regression analysis and adjusting for confounding factors such as age, AMH levels, basal follicle count, endometrial thickness, total number of oocytes obtained, cycle type, number of high-quality embryos transferred, ovarian stimulation protocol, and stage of embryo development, it was revealed that, compared to Group A, Groups B, C, and D exhibited significantly lower implantation and live birth rates, as well as a significantly higher risk of early spontaneous abortion (all P < 0.05).

Conclusions

The number of previous embryo implantation failures is an independent factor affecting implantation rate, clinical pregnancy rate, spontaneous abortion rate and live birth rate of patients underwent IVF/ICSI-ET. With the increase of the number of previous embryo implantation failures, the implantation rate, clinical pregnancy rate and live birth rate of patients underwent IVF/ICSI-ET decreased significantly, and the rate of early spontaneous abortion gradually increased.

TEAS, DHEA, CoQ10, and GH for poor ovarian response undergoing IVF-ET: a systematic review and network meta-analysis

BACKGROUND

Assisted reproductive technology (ART) has brought good news to infertile patients, but how to improve the pregnancy outcome of poor ovarian response (POR) patients is still a serious challenge and the scientific evidence of some adjuvant therapies remains controversial.

AIM

Based on previous evidence, the purpose of this systematic review and network meta-analysis was to evaluate the effects of DHEA, CoQ10, GH and TEAS on pregnancy outcomes in POR patients undergoing in vitro fertilization and embryo transplantation (IVF-ET). In addition, we aimed to determine the current optimal adjuvant treatment strategies for POR.

METHODS

PubMed, Embase, The Cochrane Library and four databases in China (CNKI, Wanfang, VIP, SinoMed) were systematically searched up to July 30, 2022, with no restrictions on language. We included randomized controlled trials (RCTs) of adjuvant treatment strategies (DHEA, CoQ10, GH and TEAS) before IVF-ET to improve pregnancy outcomes in POR patients, while the control group received a controlled ovarian stimulation (COS) regimen only. This study was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The surface under the cumulative ranking curve (SUCRA) was used to provide a pooled measure of cumulative ranking for each outcome.

RESULTS

Sixteen RCTs (2323 women) with POR defined using the Bologna criteria were included in the network meta-analysis. Compared with the control group, CoQ10 (OR 2.22, 95% CI: 1.05 to 4.71) and DHEA (OR 1.92, 95% CI: 1.16 to 3.16) had obvious advantages in improving the clinical pregnancy rate. CoQ10 was the best in improving the live birth rate (OR 2.36, 95% CI: 1.07 to 5.38). DHEA increased the embryo implantation rate (OR 2.80, 95%CI: 1.41 to 5.57) and the high-quality embryo rate (OR 2.01, 95% CI: 1.07 to 3.78) and number of oocytes retrieved (WMD 1.63, 95% CI: 0.34 to 2.92) showed a greater advantage, with GH in second place. Several adjuvant treatment strategies had no significant effect on reducing the cycle canceling rate compared with the control group. TEAS was the least effective of the four adjuvant treatments in most pooled results, but the overall effect appeared to be better than that of the control group.

CONCLUSION

Compared with COS regimen, the adjuvant use of CoQ10, DHEA and GH before IVF may have a better clinical effect on the pregnancy outcome of POR patients. TEAS needs careful consideration in improving the clinical pregnancy rate. Future large-scale RCTs with direct comparisons are needed to validate or update this conclusion.

Paths towards parenthood after repeated treatment failures: a comparative study on predictors of psychological health outcomes in infertile couples persisting in treatments or opting for adoption

Introduction

Infertility literature suggests widespread recourse to long-term medical treatments despite evidence of high stress, costs, and adverse effects of repeated treatment failures. However, there is a lack of research comparing predictors of stress and psychological health outcomes between members of infertile couples who - after repeated failures - persist in pursuing medical treatments (PT) with those who opted for quitting treatments and adopting (QTA). Basing on a transactional and multidimensional approach to infertility-related stress and health, the present study aims at exploring individual (socio-demographics; coping strategies) and situational (infertility-related parameters; infertility-related stressors; couple's dyadic adjustment dimensions) predictors of state-anxiety and depression in male and female partners of PT-infertile couples and of QTA-infertile couples.

Methods

Participants were both members of 176 couples with duration of infertility and a history of medical treatments for at least 3 years (76 PT-infertile couples, 100 QTA-infertile couples). The study variables were compared by study group across genders. Structural equation models (SEM) were used to test main and moderating effects of study variables on state-anxiety and depression by study group and across genders.

Results

Members of infertile couples quitting treatments and adopting (QTA) reported significantly lower levels of state-anxiety and depression, higher stress related to need for parenthood and rejection of childfree-lifestyle and lower stress related to social and couple's relationship concerns than those who persist in pursuing medical treatments (PT). Members of infertile couples quitting treatments and adopting (QTA) recurred to a greater extent to active coping strategies (problem-solving/social-support) and to a lower extent to passive coping strategies (avoiding/turning-to-religion), and they reported higher levels of dyadic adjustment. Specificities in main and moderating factors related to state-anxiety and depression by study group and across genders were found.

Conclusion

Findings should be addressed to provide a comprehensive assessment of both members of infertile couples facing repeated treatment failures to identify risks and resources and develop tailored evidence-based interventions.

Differences in Fertility-Related Quality of Life and Emotional Status Among Women Undergoing Different IVF Treatment Cycles

Objective

The present study aimed to provide more insight into the possible differences in the fertility-related quality of life (FertiQoL) and emotional status of women undergoing different cycles of in vitro fertilization (IVF) treatments.

Methods

A prospective cohort study was performed, and a total of 432 women undergoing IVF treatment were recruited. FertiQoL scale, self-rating anxiety scale (SAS), self-rating depression scale (SDS), and perceived social support scale (PSSS) were used to analyze fertility-related QoL and emotional status. Data were analyzed comparing women undergoing different cycles of IVF treatments.

Results

A significant decrease in FertiQoL scores occurred in women with increased cycles of IVF treatment. Both anxiety and depression scores significantly increased with increased cycles of attempting IVF treatment. There was no significant difference detected in perceived social support among groups.

Conclusion

With the increase in the number of IVF treatment cycles, women's FertiQoL gradually decreased, while the risk of anxiety and depression gradually increased.

Persevering in Fertility Treatments Despite Failures: Unrealistic Optimism and the Reality of a Pronatalist Culture

BACKGROUND

Fertility treatment discontinuation is difficult as it entails accepting childlessness. In most countries, financial limitations provide sufficient justification to terminate treatment. In Israel, unlimited funding enables women to undergo multiple treatment cycles, even when the odds of success are poor, thus providing a context for studying the psychological mechanisms involved when financial constraints are set aside. The study aimed to investigate the contribution of unrealistic optimism to Israeli women's willingness to continue fertility treatments even after repeated failures and to their psychological adjustment, comparing age groups.

METHODS

A longitudinal study of 100 women (ages 31-45) undergoing in vitro fertilization (IVF) treatment (1-22 previous cycles), who filled in questionnaires assessing their estimates of treatment success (theirs/for same-age patient), estimates received from the physician, intentions to continue treatment, and psychological adjustment. Follow-up was conducted 17(± 4) months later, by phone (n = 71) and/or medical records (n = 90).

RESULTS

Most women (57%) reported that they will continue as long as needed till they have a child, 13% did not know, and 25% mentioned a specific plan; 5 did not reply. Women's estimates of treatment success showed vast unrealistic optimism, which was unrelated to their age, history of unsuccessful treatment cycles, or intentions for treatment continuation, yet was related to better psychological adjustment. At follow-up, almost all women who did not conceive were found to have continued treatments.

CONCLUSIONS

Unrealistic optimism helps women maintain hope and well-being along the demanding journey to (biological) parenthood, where childlessness is highly stigmatized, and contributes to perseverance in treatment, regardless of objective factors.

Psychosocial correlates of fertility-related quality of life among infertile women with repeated implantation failure: The mediating role of resilience

OBJECTIVE

This study aimed to examine associations between psychosocial factors and fertility-related quality of life (FertiQoL) among infertile women with repeated implantation failure (RIF), and to identify the possible role of resilience in mediating the effect of social support on FertiQoL.

MATERIALS AND METHODS

A cross-sectional study was conducted with 234 infertile women with RIF in total. Fertility quality of life scale (FertiQoL), perceived social support scale (PSSS), and Connor-Davidson Resilience Scale (CD-RISC) were used to evaluate the patients. Data were described by univariate and multivariate analyses. Stepwise regression method was performed to analyse the mediating effect of resilience.

RESULTS

Social support had a positive predictive effect on FertiQoL (β = 0.757, P < 0.001), also positive on resilience (β = 0.847, P < 0.001). After both variables were added to the regression equation, resilience was found to have a significant positive predictive effect on FertiQoL (β = 0.798, P < 0.001), while the predictive effect of social support on FertiQoL was no longer significant (β = 0.081, P > 0.05). The results indicated that resilience played a complete mediating role between social support and FertiQoL.

CONCLUSION

This study preliminarily verified the mediating role of resilience between social support and FertiQoL among infertile women with RIF. Interventions that consider enhancing resilience and building social support will likely improve their FertiQoL.

Effects of Bushen-Tiaojing-Fang on the pregnancy outcomes of infertile patients with repeated controlled ovarian stimulation

Bushen-Tiaojing-Fang (BSTJF) is commonly used to treat infertility. This study investigated the effects of BSTJF on the pregnancy outcomes of patients with repeated controlled ovarian stimulation (COS), on mitochondrial function, and on oxidative stress in ovarian granulosa cells (GCs) and follicular fluid (FF). The samples and clinical data of 97 patients, including 35 in the control group, 29 in the placebo group and 33 in the BSTJF group, were collected for this study. The mitochondrial ultrastructure, ATP content, mitochondrial DNA (mtDNA) number, 8-hydroxy-2-deoxyguanosine (8-OHdG), Mn-superoxide dismutase (Mn-SOD), glutathione peroxidase (GSH-Px) activity levels, and mRNA expression levels of Mn-SOD, GSH-Px, and nuclear factor erythroid-derived factor 2-related factor 2 (Nrf2) were analyzed. The high-grade embryo (P < 0.001), implantation (P = 0.033), and clinical pregnancy (P = 0.031) rates, as well as the ATP content (P = 0.014), mtDNA number (P = 0.035), GSH-Px activity (P = 0.004 in GCs and P = 0.008 in FF) and mRNA expression levels (P = 0.019), were significantly lower in the placebo group than in the control group, whereas the 8-OHdG content was significantly (P = 0.006 in FF) higher in the placebo group than in the control group. Compared with those in the placebo group, the high-grade embryo rate (P = 0.007), antioxidant enzyme activity (P = 0.037 and 0.036 in Mn-SOD; P = 0.047 and 0.030 in GSH-Px) and mRNA level (P < 0.001 in Nrf2, P = 0.039 in Mn-SOD and P = 0.002 in GSH-Px) were significantly higher in the BSTJF group, as were changes in mitochondrial ultrastructure, ATP (P = 0.040) and mtDNA number (P = 0.013). In conclusion, BSTJF can improve oxidative stress in patients with repeated COS and pregnancy outcomes.

Analysis of the levels of hope and influencing factors in infertile women with first-time and repeated IVF-ET cycles

Purpose

To explore the hope levels and influencing factors in infertile women undergoing first-time and repeated in vitro fertilization-embryo transfer (IVF-ET) cycles.

Methods

This study was a cross-sectional and convenient sampling study conducted among patients undergoing IVF-ET from January to June 2019. Patients were divided into first-time and repeated groups by the number of IVF-ET cycles, and then a questionnaire survey was administered. The questionnaire included demographic information, Herth hope index (HHI) scale, Locke-Wallace short marital-adjustment test scale and social support rating scale. Multiple linear regression was used to analyse the influencing factors associated with hope levels.

Results

A total of 298 IVF-ET patients were recruited for the study, including 150 (50.3%) in the first-time cycle group and 148 (49.7%) in the repeated cycle group. The HHI score of the repeated cycle group was significantly lower than that of the first-time cycle group (34.4 ± 3.5 vs. 37.5 ± 3.7, P < 0.001). Multiple linear regression analysis indicated that repeated IVF-ET and age were independently negatively correlated with HHI, with standardized coefficient β values of − 0.895 and − 0.223, respectively (both P < 0.001). High education level (P = 0.002), high monthly income (P = 0.020), high degree of short marital-adjustment test (P < 0.001) and social support rating (P < 0.001) were independently positively correlated with HHI.

Conclusion

Infertile women undergoing repeated IVF-ET have low hope levels. Maintaining a good marriage adjustment and establishing a good social support and relationship network could effectively improve their hope levels.

Hope level is closely related to patients' mental health and emotional state. Therefore, improving the hope level of infertile women with IVF-ET could contribute to relieving the psychological pressure of patients and improving the success rate of pregnancy. This study aimed to evaluate the hope level of infertile women with different IVF-ET cycles and analyse its influencing factors to provide guidance for clinical nurses to clarify the intervention objects, select reasonable intervention measures and improve the hope levels of patients. A total of 298 IVF-ET patients were recruited in the study, including 150 in the first-time cycle group and 148 in the repeated cycle group. The results showed that the hope level of patients with repeated IVF-ET cycles was significantly lower than that of patients undergoing first-time treatment. We also analysed its influencing factors and found that repeated IVF-ET cycles and age were independent negative correlation factors in hope levels. High monthly income, living in the city, high marital adjustment and social support score were independent positive correlation factors in hope levels. Therefore, maintaining a good marriage adjustment and establishing a good social support and relationship network could effectively improve their hope levels.

Effects of changing culture medium on preimplantation embryo development in rabbit

Many studies have focused on the optimization of the composition of embryo culture medium; however, there are few studies involving the effect of a culture medium changing procedure on the preimplantation development of embryos. In this study, three groups were designed: a non-renewal group, a renewal group and a half-renewal group. The levels of reactive oxygen species (ROS), apoptotic index, blastocyst ratio and blastocyst total cell number were analyzed in each group. The results showed that the ROS level and the apoptotic index of blastocyst in the non-renewal group were significantly higher than in the renewal group and the half-renewal group (P < 0.05). The blastocyst ratio and blastocyst total cell number were significantly higher in the half-renewal group than that in non-renewal group and the renewal group (P < 0.05). These results demonstrated that the procedure of changing the culture medium influenced ROS level, apoptotic index, blastocyst ratio and total cell number of blastocysts. In addition, the result suggested that changing the culture medium may lead to a loss of important regulatory factors for embryos, while not changing the culture medium may lead to the accumulation of toxic substances. Half-renewal can alleviate the defects of both no renewal and renewal, and benefit embryo development. This study will be of high value as a reference for the optimization of embryo culture in vitro, and is very significant for assisted reproduction.

Effects of multicycle gonadotropin-releasing hormone antagonist protocols on oxidative stress of follicular fluid and ovarian granulosa cells

The effect of repeated multicycle gonadotropin-releasing hormone antagonist (GnRH-ant) protocols on oxidative stress (OS) in follicular fluid (FF) and ovarian granulosa cells (GCs) remains unclear. This study investigated the effects of repeated multicycle GnRH-ant protocols on OS markers of FF and ovarian GCs. A total of 145 patients were enrolled and divided into four groups: 1 cycle group (n = 42), 2 cycles group (n = 37), 3 cycles group (n = 45), and 4-5 cycles group (n = 21). The FF and ovarian GCs of the patients were collected on the day of last oocyte retrieval and the levels of 8-hydroxy-2-deoxyguanosine (8-OHdG), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) were tested by ELISA. The results showed that the serum estradiol levels on hCG injection day in the 3 and 4-5 cycles were significantly (P < 0.05) lower than in the 1 and 2 cycles. The number of retrieved oocytes (12.1 ± 3.3 in cycle 1, 11.7 ± 3.1 in cycle 2, 10.4 ± 2.4 in cycle 3, and 9.4 ± 2.4 in cycles 4-5), embryos with two pronuclei (7.6 ± 3.0 in cycle 1, 7.0 ± 2.5 in cycle 2, 6.2 ± 2.6 in cycle 3, and 5.5 ± 2.1 in cycles 4-5), and the rates of high-quality embryos (52.2% in cycle 1, 47.9% in cycle 2, 38.6% in cycle 3, and 36.5% in cycles 4-5), implantation (35.4% in cycle 1, 32.4% in cycle 2, 23.8% in cycle 3, and 22.9% in cycles 4-5) and clinical pregnancy (50.0% in cycle 1, 43.2% in cycle 2, 33.3% in cycle 3, and 23.8% in cycles 4-5) in cycles 3 and 4-5 were significantly (P < 0.05) lower than those in cycles 1 and 2. Compared with 1 and 2 cycles, the 8-OHdG and SOD were significantly increased in the 3-5 cycles, while the CAT and GSH-Px levels were significantly decreased. Together, this study reveals repeated COS with the use of GnRH-ant protocols results in OS and changes the follicle microenvironment of FF and GCs, possibly leading to poor IVF outcomes in patients with 3-5 cycles of COS.

Gene Editing, Enhancing and Women's Role

A recent article on the front page of The Independent (September 18, 2015) reported that the genetic 'manipulation' of IVF embryos is to start in Britain, using a new revolutionary gene-editing technique, called Crispr/Cas9. About three weeks later (Saturday 10, October 2015), on the front page of the same newspaper, it was reported that the National Health Service (NHS) faces a one billion pound deficit only 3 months into the new year. The hidden connection between these reports is that gene editing could be used to solve issues related to health care allocation. Improving the health of future generations might coincide with public health goals; it might improve the health of individuals and communities, and, if successful, might be seen as a public good. However, enhancing future generations will require In Vitro Fertilisation and Pre-implantation Genetic Diagnosis. Remarkably, the necessary involvement of women in an enhancing scenario has not been discussed by its proponents. The present discourse on moral obligations of future generations, although not referring to women, seems to imply that women might be required, morally, if not legally, to reproduce with IVF. Enhancing future generations will be gendered, unless the artificial womb is developed. These are challenging issues that require a wider perspective, of both women and men. Despite the lack of a unified feminist conclusion in the discussions about the merits and risks of human genome modification, there is an urgent need to clarify the role of women in this scenario.

Preimplantation embryos sex ratios in couples with four or more children of same sex, what should be expected from a preimplantation genetic diagnosis cycle?

Our aim was to assess the preimplantation embryos' sex ratios in couples with four or more children of same sex, undergoing sex selection for nonmedical reasons. We conducted a cohort-historical study of all consecutive patients admitted to the IVF-PGD program in a large tertiary center. We reviewed the computerized files of all consecutive women admitted to our IVF for sex selection for nonmedical reasons. Patients and their PGD cycle characteristics were compared according to the desired sex of their embryo and the mode of fertilization. Nine patients underwent a total of 19 PGD cycle attempts during the study period. Of the 77 embryos with complete molecular diagnosis, 41 revealed a male embryo and 36 a female embryo. Thirty-five percent of all the diagnosed embryos were of the desired sex. For couples desiring a boy, IVF cycles achieved a higher ratio of the desired embryonal sex compared to ICSI (52% vs 18.7%, p = .03). For couples desiring a girl, ICSI cycles had a higher percentage of the desired embryonal sex compared to IVF cycles (38% vs 23%). Moreover, 29.7% of ICSI and 40% of IVF embryos achieved the desired sex. In conclusion, PGD for sex selection results in a relatively low percentage (35%) of embryos demonstrating the desired sex. Nonetheless, selecting the mode of fertilization (ICSI/IVF) might improve the success rate. Further studies are required to explore the appropriate and cost-effective method for sex selection for nonmedical reasons.

Does the empty follicle syndrome occur in cases of low number of maturing follicles in assisted reproduction?

The pathophysiology of the genuine empty follicle syndrome (EFS) is still debated. Ovarian aging has been contested as a cause of this condition. Our aim was to investigate the occurrence of the genuine EFS in cases of a low number of mature follicles in a prospective manner. Ninety-five infertile women were recruited and evaluated following conventional controlled ovarian stimulation (COS) with ≤ six follicles of ≥14 mm diameter on the day of hCG administration. Enrolled women were 37.5 ± 5.2 years of age with basal FSH level of 9.1 ± 3.7 mIU/L, antral follicle count (AFC) of 6.9 ± 4.6, and number of ≥14 mm follicles (on the day of hCG) of 3.4 ± 1.5. Among the 95 women, four were complicated by the genuine EFS (4.2%) with features of the depleted ovarian reserve. Comparison between these four cases and the 91 controls revealed significant differences between age, AFC, number of ≥14 mm follicles, and serum E₂ level corresponding to 41.8 ± 1.7 versus 37.4 ± 5.2 years, 1.7 ± 0.6 versus 7.1 ± 4.5, 2.0 ± 0.8 versus 3.4 ± 1.5 follicles, and 356 ± 200 versus 975 ± 557 pg/mL, respectively. Post hoc analysis revealed that 56 among the 95 women fulfilled the Bologna criteria for poor ovarian response and all four cases matched the definition of the genuine EFS raising its incidence to 7.1% in this group. A logistic regression analysis showed that AFC was a significant factor in the development of the genuine EFS. We conclude that the genuine EFS complicates infertile women characterized by a low number of mature follicles. Our findings suggest that the mechanism behind this occurrence is associated with a more exhausted ovarian reserve.

In Vitro fertilization (IVF) treatments in Maccabi Healthcare Services 2007-2014

BACKGROUND

Israel reports the world's highest IVF cycles per capita. However, clinical outcome data of these treatments are scarce. In a previous publication, we summarized IVF results among Maccabi Healthcare Services members for the years 2007-2010. The main findings included an increase in mean patients' age over the period studied, a 50 % increase in cycle numbers during this time, and a decrease in success rate (live birth) from 18.8 % in 2007 to 14.8 % in 2010. The purpose of the current publication is to summarize IVF outcome for the years 2011-2014, and to explore possible changes in the trends we reported previously.

METHODS

IVF and live births data were collected from Maccabi Healthcare Services' fertility treatments registry. Analyses were conducted by treatment year and patients' age at the initiation of treatment cycles. Autologous cycles, were included (ovum donation cycles and frozen-thaw cycles were excluded). A successful cycle was defined if a live birth was recorded within 10 months of its initiation.

RESULTS

In accordance with previous data for the years 2007-2010, mean patients' age continued to rise (from 36.2 in 2011 to 37.1 in 2014). In contrast to previous years, during which a continued increase in treatment cycles was recorded, we found that treatment number decreased from a peak of 9,751 in 2011 to 8,623 in 2014. Contrary to that trend, the number of patients over 40 years of age increased from 3,204 in 2011 to 3,648 in 2014. Success rate fluctuated between 14.4 % in 2014 to 16.4 % in 2013. The majority (78 %) of treatment cycles were conducted in four private medical centers.

CONCLUSIONS

The decrease in treatment cycles in recent years notwithstanding, Israel is still leading the world with IVF treatments relative to population. Success rate is relatively low compared to international data. Given the steady increase in patients' mean age, and particularly, the increase in patients over 40 years of age, we maintain that the low success rate reflects a growing number of treatments that a priori have a low chance of success.

The Bologna criteria for poor ovarian response: a contemporary critical appraisal

Postponement of child bearing and maternal age at first pregnancy are on the rise, contributing considerably to an increase in age-related infertility and the demand for assisted reproductive technologies (ART) treatment. This brings to the infertility clinics many women with low ovarian reserve and poor ovarian response (POR) to conventional stimulation. The Bologna criteria were released to standardize the definition of POR and pave the way for the formulation of evidence-based, efficient modalities of treatment for women undergoing IVF-ET. More than four years have passed since the introduction of these criteria and the debate is still ongoing whether a revision is due. Women with POR comprise several sub-groups with diverse baseline distinctiveness, a major issue that has fueled the discussion. Although antral follicle count (AFC) and anti-Müllerian hormone (AMH), are considered good predictors of ovarian reserve, their threshold values are still not universally standardized. Different definitions for sonographic AFC and diverse assays for AMH are held responsible for this delay in standardization. Adding established risk factors to the criteria will lead to more reliable and reproducible definition of a POR, especially in young women. The original criteria did not address the issue of oocyte quality, and the addition of risk factors may yield specific associations with quality vs. quantity. Patient’s age is the best available criterion, although limited, to predict live-birth and presumably oocyte quality. High scale studies to validate these criteria are still missing while recent evidence raises concern regarding over diagnosis.

What Israeli policy can teach us about elective sex selection

PIGD for gender selection for non medical reasons has been a subject of ethical, legal, and moral debate in many Western countries. This article discusses the background of elective sex selection, and highlights the impact of new technological developments on this dynamic discussion. The article published by Pessach et al., in this Journal, is an excellent study of Israeli health policy on non medically indicated preimplantation genetic screening for sex selection. In Israel, elective sex selection is prohibited, but exceptions can be made by application, for family balancing, and emotional and religious reasons. This review of a health policy over seven years is concordant with evolving views in many Western countries. The classic medical model for allowing sex selection for serious medical disorders may be too restrictive. There are different reasons that may be assessed in light of ethical criteria including a wider delineation of medical reasons, which may include emotional and psychological well being of the family, indirect medical reasons, as well as risk reduction for the following generations. The Israeli model may be a useful approach with wide application to reproductive health policies in many countries.
