Oocyte Or Embryo Donation to Women of Advanced Reproductive Age: an Ethics Committee Opinion ASRM PAGES Oocyte or embryo donation to women of advanced reproductive age: an Ethics Committee opinion Ethics Committee of the American Society for Reproductive Medicine American Society for Reproductive Medicine, Birmingham, Alabama Advanced reproductive age (ARA) is a risk factor for female infertility, pregnancy loss, fetal anomalies, stillbirth, and obstetric com- plications. Oocyte donation reverses the age-related decline in implantation and birth rates of women in their 40s and 50s and restores pregnancy potential beyond menopause. However, obstetrical complications in older patients remain high, particularly related to oper- ative delivery and hypertensive and cardiovascular risks. Physicians should perform a thorough medical evaluation designed to assess the physical fitness of a patient for pregnancy before deciding to attempt transfer of embryos to any woman of advanced reproductive age (>45 years). Embryo transfer should be strongly discouraged or denied to women of ARA with underlying conditions that increase or exacerbate obstetrical risks. Because of concerns related to the high-risk nature of pregnancy, as well as longevity, treatment of women over the age of 55 should generally be discouraged. This statement replaces the earlier ASRM Ethics Committee document of the same name, last published in 2013 (Fertil Steril 2013;100:337–40). (Fertil SterilÒ 2016;106:e3–7.

Reproductive Medicine Associates of New Jersey, Morristown NJ, USA. Accepted 16 July, 2010 A retrospective cohort analysis of patients undergoing IVF cycles at an academic IVF center was performed to test the hypothesis that male age may influence aneuploidy rates in first trimester pregnancy losses. All patients had a first trimester pregnancy loss followed by evacuation of the pregnancy and karyotyping of the abortus. Couples undergoing anonymous donor oocyte ART cycles (n = 50) and 23 couples with female age less than 30 years undergoing autologous oocyte ART cycles were included. The oocyte age was less than 30 in both groups; thereby allowing the focus to be on the reproductive potential of the aging male. The main outcome measure was the effect of paternal age on aneuploidy rate. No increase in aneuploidy rate was noted with increasing paternal age (<40 years = 25.0%; 40-50 years = 38.8%; >50 years = 25.0%). Although there was a significant difference in the male partner age between oocyte recipients and young patients using autologous oocytes (33.7 7.6 vs.

  • Induction Indication: Advanced Maternal Age
    INDUCTION INDICATION: ADVANCED MATERNAL AGE DOCUMENT TYPE: REFERENCE TOOL Level of Evidence INDUCTION INDICATION: Maternal Age ≥ 40 years RECOMMENDATION: Offer Induction at ≥ 39 weeks gestation Recommendation for labour induction: II-B Recommendation for timing of labour induction: II-B Recommendations for priority: II-B Definition The average age of childbirth is rising in developed countries. The definition of advanced maternal age for the purposes of this document is greater than or equal to 40 years of age. Studies report that advanced maternal age is associated with increased pregnancy risk for both mother and baby. Although the incidence of stillbirth at term is low, it is higher in women of advanced maternal age.1 Outcomes There are known adverse perinatal outcomes for women who are of advanced maternal age. When compared to younger women, in older women there is increased risk for placental abruption, placenta previa, malpresentation, growth restriction, preterm and postdates delivery as well as postpartum hemorrhage. Even after controlling for medical co-morbidities, advanced maternal age is found to be associated with an increase in antenatal and intrapartum stillbirth.2 The relative risk of stillbirth for women ≥ 40 years of age, for both multiparous and primiparous women is 1.2 to 4.5. The cumulative risk of stillbirth in women 40 and older at 39 weeks gestation is similar to mothers 25 to 29 years at 41 weeks gestation3,4. The mechanism for increased risk of stillbirth in older mothers is as yet unknown. Recommendations Labour induction may be offered to mothers who are greater than or equal to 40 years of age at 39 weeks of gestation.

    The SO(H)L(H) “O” drivers of oocyte growth and survival but not meiosis I T. Rajendra Kumar J Clin Invest. 2017;127(6):2044-2047. https://doi.org/10.1172/JCI94665. Commentary Development Reproductive biology The spermatogenesis/oogenesis helix-loop-helix (SOHLH) proteins SOHLH1 and SOHLH2 play important roles in male and female reproduction. Although previous studies indicate that these transcriptional regulators are expressed in and have in vivo roles in postnatal ovaries, their expression and function in the embryonic ovary remain largely unknown. Because oocyte differentiation is tightly coupled with the onset of meiosis, it is of significant interest to determine how early oocyte transcription factors regulate these two processes. In this issue of the JCI, Shin and colleagues report that SOHLH1 and SOHLH2 demonstrate distinct expression patterns in the embryonic ovary and interact with each other and other oocyte-specific transcription factors to regulate oocyte differentiation. Interestingly, even though there is a rapid loss of oocytes postnatally in ovaries with combined loss of Sohlh1 and Sohlh2, meiosis is not affected and proceeds normally.

    Induction of Labour at Term in Older Mothers Scientific Impact Paper No. 34 February 2013 Induction of Labour at Term in Older Mothers 1. Background and introduction The average age of childbirth is rising markedly across Western countries.1 In the United Kingdom (UK) the proportion of maternities in women aged 35 years or over has increased from 8% (approximately 180 000 maternities) in 1985–87 to 20% (almost 460 000 maternities) in 2006–8 and in women aged 40 years and older has trebled in this time from 1.2% (almost 27 000 maternities) to 3.6% (approximately 82 000 maternities).2 There is a continuum of risk for both mother and baby with rising maternal age with numerous studies reporting multiple adverse fetal and maternal outcomes associated with advanced maternal age. Obstetric complications including placental abruption,3 placenta praevia, malpresentation, low birthweight,4–7 preterm8 and post–term delivery9 and postpartum haemorrhage,10 are higher in older mothers. As fertility declines with age, there is a greater use of assisted reproductive technologies (ARTs) and the possibility of multiple pregnancy increases. This may independently adversely affect the risks reported.11 Preexisting maternal medical conditions including hypertension, obesity and diabetes increase with advancing maternal age as do pregnancy–related maternal complications such as pre–eclampsia and gestational diabetes.12 These medical co–morbidities can all influence fetal health and are likely to compound the effect of age on the risk of pregnancy in an older

No portion herein may be reproduced in any form without written permission. This booklet is in no way intended to replace, dictate or fully define evaluation and treatment by a qualified physician. It is intended solely as an aid for patients seeking general information on issues in reproductive medicine. Copyright © 2012 by the American Society for Reproductive Medicine AMERICAN SOCIETY FOR REPRODUCTIVE MEDICINE Age and Fertility A Guide for Patients Revised 2012 A glossary of italicized words is located at the end of this booklet. INTRODUCTION Fertility changes with age. Both males and females become fertile in their teens following puberty. For girls, the beginning of their reproductive years is marked by the onset of ovulation and menstruation. It is commonly understood that after menopause women are no longer able to become pregnant. Generally, reproductive potential decreases as women get older, and fertility can be expected to end 5 to 10 years before menopause. In today’s society, age-related infertility is becoming more common because, for a variety of reasons, many women wait until their 30s to begin their families. Even though women today are healthier and taking better care of themselves than ever before, improved health in later life does not offset the natural age-related decline in fertility. It is important to understand that fertility declines as a woman ages due to the normal age- related decrease in the number of eggs that remain in her ovaries.
