The risks and outcome of pregnancy in an advanced maternal age in oocyte donation cycles

Against age limits for men in reproductive care

Almost all countries and fertility clinics impose age limits on women who want to become pregnant through Assisted Reproductive Technologies (ART). Age limits for aspiring fathers, however, are much less common and remain a topic of debate. This article departs from the principle of reproductive autonomy and a conditional positive right to receive ART, and asks whether there are convincing arguments to also impose age limits on aspiring fathers. After considering three consequentialist approaches to justifying age limits for aspiring fathers, we take in a concrete normative stance by concluding that those are not strong enough to justify such cut-offs. We reinforce our position by drawing a comparison between the case of a 39-year-old woman who wants to become a single mother via a sperm donor on the one hand, and on the other hand the same woman who wants to have a child with a 64-year-old man who she loves and who is willing to care for the child as long as he is able to. We conclude that, as long as appropriate precautions are taken to protect the welfare of the future child, couples who want to receive fertility treatment should never be limited on the basis of the age of the (male) partner. An absence of age limits for men would respect the reproductive autonomy of both the man and the woman.

Mapping Ethical, Legal, and Social Implications (ELSI) of gamete donation

RESEARCH QUESTION

This scoping review investigates the Ethical, Legal, and Social Implications (ELSI) of gamete donation, a critical facet of Assisted Reproductive Technologies, by analyzing the evolving research scope, methodological approaches, and the geographical skew in the literature. Despite the increased global uptake of donor gametes, current scholarship predominantly emanates from Western contexts and focuses on majoritized groups. This bias constrains the universality of research findings and limits their applicability across varied legal, cultural, and social contexts, underscoring a need for broader inclusivity.

DESIGN

We addressed 867 pivotal articles published between 1999 and 2019.

RESULTS

Our analysis reveals a discernible escalation in research volume, with 62% based on empirical research. The intellectual landscape unfolds into four dominant clusters: Regulatory Frameworks, Incentives, and Access; Family Dynamics and Genetic Linkages; Identity and Privacy in Donor Conception; and Cultural and Societal Attitudes towards GD. Each cluster highlights nuanced dimensions of gamete donation, from regulatory intricacies and psychological welfare to identity ethics and cultural perceptions.

CONCLUSION

Our findings advocate for a shift towards more globally representative and methodologically inclusive research. By integrating diverse cultural narratives and expanding geographical breadth, future research can offer holistic understandings of gamete donation, fostering equitable and culturally resonant practices and policies worldwide.

Evidence-Based Pre-Pregnancy Counseling for Oocyte Donation Pregnancies: a Systematic Review and Guide for Physicians

It is well known that oocyte donation (OD) pregnancies are associated with higher complication rates compared to autologous pregnancies. However, evidence-based information for pre-pregnancy counseling designed for health care workers is scarce. Therefore, a systematic literature search was performed to find articles that address pre-pregnancy counseling before OD.A systematic search was conducted in September 2020 in various databases, including PubMed and Embase. Nine (systematic) reviews and meta-analyses were included that reported on pre-pregnancy advice in OD pregnancies.Studies are consistent in documenting a higher risk for hypertensive disorders, cesarean section, preterm birth, postpartum hemorrhage, and low birth weight. Based on these complications, pre-pregnancy advice is mentioned in all included systematic reviews to prevent complications in the next pregnancy. All studies recommend counseling women on the increased risk of complications during OD pregnancy. Other recommendations include the prophylactic use of aspirin in pregnancy and restriction to single embryo transfer. Individualized appropriate surveillance and management strategies should be considered for every patient achieving pregnancy by OD.In conclusion, we provide a summary of the most important outcomes in OD pregnancies, and thereby offer a guide for pre-pregnancy counseling.

Impact of oocyte donation on obstetric and perinatal complications in twin pregnancies

Aim: To evaluate obstetric and perinatal outcomes of twin pregnancies obtained after in vitro fertilization with donated oocytes.Methods: This is a case-control study comparing 50 women with twin pregnancies after oocyte donation (OD) and 50 women after in vitro fertilization with autologous oocytes. Clinical records were reviewed and obstetric and perinatal outcome variables including rates of preeclampsia, gestational diabetes, pregnancy-induced hypertension, preterm delivery, premature rupture of membranes, cesarean delivery, birth weight, Apgar score, pH test were compared.Results: Women in the OD group were significantly older than those in the AO group (mean 40.8 versus 36 years old, p < .001). There were a higher risk of preeclampsia (OD 24% versus AO 8%), cesarean delivery (OD 90% versus AO 66%), and preterm birth before 37 weeks (OD 52% versus AO 32%). After adjustment for maternal age, only the risk of preterm birth remained significantly higher (OR 3.2 (1.15-8.86); p = .025). Comparing neonatal outcomes, there were no differences in birth weight, pH or Apgar score at birth.Conclusions: Twin pregnancies after OD are associated with a higher risk of preterm birth before 37 weeks of gestation. However, this did not translate into increased rate of adverse perinatal outcomes.

Complications of the third stage of labor are more prevalent in IVF pregnancies

Background: Pregnancies conceived by in vitro fertilization (IVF) are associated with a higher prevalence of perinatal complications than pregnancies conceived spontaneously, even after correction of confounding factors. Little is known about the prevalence of complications of the third stage of labor in IVF pregnancies.Objective: To compare the prevalence and types of complications of the third stage of labor following vaginal delivery of singleton infants born to matched groups of women who conceived through IVF or spontaneously.Study design: A retrospective case-control study design was used. The electronic delivery files of a tertiary medical center were reviewed for all women with a singleton IVF pregnancy who gave birth by vaginal delivery from August 2011 to March 2014. The women were matched 1:2 for age, gravidity, parity, and week of delivery to women with a singleton spontaneously conceived pregnancy who gave birth by vaginal delivery during the same period at the same hospital. The impact of mode of conception on the length and complications of the third stage of labor was evaluated.Results: The study group consisted of 242 women with IVF pregnancies (cases), and 484 matched controls with spontaneously conceived pregnancies (controls). The length of the third stage was similar in the cases and controls (14.23 ± 8.89 and 13.69 ± 9.19 min, respectively). IVF pregnancy was associated with a significantly higher rate of postpartum hemorrhage (PPH) (5.79 versus 1.45%, p = .001), manual removal of retained placenta (11.98 versus 7.02%, p = .025), and blood transfusion (2.07 versus 0.41%, p = .032). On multivariate analysis, pregnancy conceived by IVF was an independent risk factor for an adverse outcome of the third stage of labor (OR 2.86, 95% CI 1.53-5.33).Conclusion: After correction for confounders, IVF conception proved to be a significant independent risk factor for PPH, manual removal of the placenta, and blood transfusion in the third stage of labor. Therefore, the management of women who give birth vaginally following IVF pregnancy should be designed to anticipate complications in the third stage even in the absence of other risk factors.

Frozen embryo transfer at the cleavage stage can be performed within the first menstrual cycle following the freeze-all strategy without adversely affecting the live birth rate: A STROBE-compliant retrospective study

Thus far, all clinical trials evaluating the efficacy of embryo transfer strategies have selectively delayed the first frozen embryo transfer (FET) by at least 1 menstrual cycle. Nevertheless, this approach, which is based solely on clinical experience, may create unnecessary psychological stress on infertile patients who are anxious to conceive as soon as possible. This study aimed to investigate whether the time interval between oocyte retrieval and subsequent FET affects reproductive outcomes.We implemented a large retrospective cohort study in a single assisted reproductive technology (ART) unit at a university-based hospital, including 1540 autologous FET cycles performed in freeze-all cycles. The beginning of the FET was classified as either 'cycle 1' (performing FET within the first menstrual cycle) or 'cycle ≥2' (performing FET after one or more menstrual cycles). Live birth rate (LBR) was the primary outcome of our study.The mean interval for 'cycle 1' and 'cycle ≥2' FETs was 25.72 ± 5.10 days and 75.33 ± 24.85 days, respectively (P < .001). The type of controlled ovarian hyperstimulation (COH) and endometrial preparation protocols differed significantly between groups (P = .008 and P = .004, respectively). However, FET groups were similar in many ways. Univariate analysis showed that there was no significant difference in LBR between the different cycles (33.1% after 'cycle 1' FET vs 34.2% after 'cycle ≥2' FET, P = .68). To evaluate whether LBR remained unchanged after adjustment for potential confounders, we performed multivariate logistic regression. FET timing had no significant impact on LBR in the first FET (odds ratio [OR]: 1.06, 95% confidence interval [CI]: 0.80-1.39).In accordance with the present study, it might not be necessary for clinicians to wait more than 1 menstrual cycle before performing FET. This allows us to reduce otiose deferment in FET, without adversely affecting reproductive outcomes.

Socio-demographic factors associated with delayed childbearing in Nigeria

Objective

Delayed childbearing is an emerging public health issue in developing countries compared with more developed countries, where it is already a major clinical and public health concern. Previous studies have mostly focused on either the health risks associated with delayed childbearing or the reasons for it with little done around the socio-demographic factors associated with it in developing countries. The objective of the study was to examine associated socio-demographic factors of delayed childbearing in Nigeria.

Results

The study used secondary data pooled from 2003 to 2013 Nigeria Demographic and Health Surveys. The outcome variable was delayed childbearing. The explanatory variables are selected individual socio-demographic characteristics and community characteristics. A weighted sample size of 20,550 women was analysed. Results showed a prevalence of 8.0% delayed childbearing in Nigeria. Socio-demographic factors such as higher maternal education, age at first marriage of 25 years or older, modern contraceptive use, and remarriage status were significantly associated with delayed childbearing. Significant associations were also observed with high community literacy level and high proportion of women who ever used modern contraceptive in the community.

The contribution of multiple pregnancies from overseas fertility treatment to obstetric services in a Western Australian tertiary obstetric hospital

BACKGROUND

Increasingly couples are travelling overseas to access assisted reproductive technology, known as cross border reproductive care, although the incidence, pregnancy outcomes and healthcare costs are unknown.

AIMS

To determine obstetric and neonatal outcomes for multiple pregnancies conceived through fertility treatment overseas, and estimate cost of these pregnancies to the health system.

MATERIALS AND METHODS

Retrospective study of women receiving care for a multiple gestation between July 2013 and June 2015 at Western Australia's sole tertiary obstetric hospital, where conception was by overseas fertility treatment. Obstetric and neonatal outcomes were recorded and cost estimates calculated.

RESULTS

Of 11 710 births, 422 were multiple pregnancies. Thirty-seven pregnancies were conceived with fertility treatment, with 11 (29.7%) conceived overseas. Median antenatal clinic attendances, ultrasound examinations, and fetal assessments for the overseas fertility cases were six, 10, and nine, respectively. The gestational age at delivery ranged from 30 to 38 weeks (median 34 + 1). Median neonatal admission duration was 18 days (range 0-47). Cost for obstetric care was estimated between $170 000 and $216 000, and cost of neonatal care was estimated as $810 000, giving a combined total cost of between $980 000 and $1 026 000.

CONCLUSION

At the sole tertiary obstetric centre in WA, approximately one-third of all multiple pregnancies conceived with fertility treatment resulted from treatment overseas. The Australian healthcare cost for these 11 women and their infants exceeded $1 000 000. This study suggests that overseas fertility treatment has a significant health-related cost to the mother and infant, and the local healthcare system.
