Commercialization, Altruism, Clinical Practice: Seeking Explanation for Similarities and Differences in Californian and Canadian Gestational Surrogacy Outcomes

Bridging Reproductive and Productive Work: The Case of Surrogates in California

In this article, we explore the perspectives of commercial gestational surrogates in California, USA. Women who gestate for others reveal themselves as important agents in the process of giving meaning and cultural legitimacy to their practice, thus demonstrating their capacity to act in their own interest and resignify their work in their own terms. To them, surrogacy is more than wage labor. They assert the importance of their experience as a source of professional skills, downplaying its monetary value and placing it within favorable moral frameworks, thus finding cultural legitimacy. In doing so, they bridge the divide between traditional female reproductive work (unpaid emotional, relational, and care work) and productive work (paid professional work in the public sphere). They achieve this without subverting the underlying values of western kinship. The results shed light on employability and entrepreneurship of surrogates in the fertility industry of California.

46,XX Differences of Sex Development outside congenital adrenal hyperplasia: pathogenesis, clinical aspects, puberty, sex hormone replacement therapy and fertility outcomes

The term 'differences of sex development' (DSD) refers to a group of congenital conditions that are associated with atypical development of chromosomal, gonadal, and/or anatomical sex. DSD in individuals with a 46,XX karyotype can occur due to fetal or postnatal exposure to elevated amount of androgens or maldevelopment of internal genitalia. Clinical phenotype could be quite variable and for this reason these conditions could be diagnosed at birth, in newborns with atypical genitalia, but also even later in life, due to progressive virilization during adolescence, or pubertal delay. Understand the physiological development and the molecular bases of gonadal and adrenal structures is crucial to determine the diagnosis and best management and treatment for these patients. The most common cause of DSD in 46,XX newborns is congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, determining primary adrenal insufficiency and androgen excess. In this review we will focus on the other rare causes of 46,XX DSD, outside CAH, summarizing the most relevant data on genetic, clinical aspects, puberty and fertility outcomes of these rare diseases.

The future of surrogacy: a review of current global trends and national landscapes

The practice of surrogacy is frequently the subject of media, scientific, social, regulatory and policy attention. Although it is, for many, an accepted form of assisted reproduction for those who would otherwise not be able to have children, surrogacy often generates strong feeling, particularly where there is any possibility of exploitation. Therefore, there is disagreement about how it should be regulated. In some countries, surrogacy is prohibited in any form, although this does not stop people using it. In others, it is unregulated but still practised. In some nations it is regulated in either a 'commercial' or an 'altruistic' model. This review article considers the possible regulatory future of surrogacy, initially from a UK perspective considering a recent review of the legal framework in a country where surrogacy works well (although some cross borders to access it), and then through an assessment of global trends and other national perspectives. It concludes that the international regulation of surrogacy, although potentially desirable, is unlikely. This being the case, it would be preferable for individual nations to regulate surrogacy so it can be undertaken in ways that are safe, ethical and protective of the best interests of children, surrogates, intended parents and families.

Molecular Basis of Müllerian Agenesis Causing Congenital Uterine Factor Infertility-A Systematic Review

Infertility affects around 1 in 5 couples in the world. Congenital absence of the uterus results in absolute infertility in females. Müllerian agenesis is the nondevelopment of the uterus. Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a condition of uterovaginal agenesis in the presence of normal ovaries and the 46 XX Karyotype. With advancements in reproductive techniques, women with MA having biological offspring is possible. The exact etiology of MA is unknown, although several genes and mechanisms affect the development of Müllerian ducts. Through this systematic review of the available literature, we searched for the genetic basis of MA. The aims included identification of the genes, chromosomal locations, changes responsible for MA, and fertility options, in order to offer proper management and counseling to these women with MA. A total of 85 studies were identified through searches. Most of the studies identified multiple genes at various locations, although the commonest involved chromosomes 1, 17, and 22. There is also conflicting evidence of the involvement of various candidate genes in the studies. The etiology of MA seems to be multifactorial and complex, involving multiple genes and mechanisms including various mutations and mosaicism.

Australian intended parents' decision-making and characteristics and outcomes of surrogacy arrangements completed in Australia and overseas

Markets for international surrogacy often arise in jurisdictions with limited regulations regarding assisted reproductive technologies. In some countries, like Australia, regulated domestic surrogacy services are often sidestepped for international providers. This study describes how Australian intended parents decide where to pursue surrogacy and compares the characteristics and outcomes of arrangements completed within and outside of Australia. The findings show that, although intended parents preferred undergoing surrogacy in Australia, perceiving the process as too long and complicated was a common reason to pursue an international arrangement. Multiple embryo transfer, anonymous gamete donation, and a lack of counselling were common in international surrogacy arrangements. When compared to surrogacy arrangements completed in Australia, where single embryo transfer is mandatory for surrogacy cycles, the rates of multiple birth, preterm birth and neonatal intensive care in international surrogacy were higher. These findings raise concerns about the health and welfare of international surrogacy participants, particularly the surrogates and children. In lieu of any international instrument regulating surrogacy, improving access to surrogacy at a domestic level would reduce the number of people engaging with international arrangements and in turn, reduce the potential for harm.

Update on Mayer-Rokitansky-Küster-Hauser syndrome

This review presents an update of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome on its etiologic, clinical, diagnostic, psychological, therapeutic, and reproductive aspects. The etiology of MRKH syndrome remains unclear due to its intrinsic heterogeneity. Nongenetic and genetic causes that may interact during the embryonic development have been proposed with no definitive etiopathogenesis identified. The proportion of concomitant extragenital malformations varies in different studies, and the discrepancies may be explained by ethnic differences. In addition to physical examination and pelvic ultrasound, the performance of pelvic magnetic resonance imaging is crucial in detecting the presence of rudimentary uterine endometrium. MRKH syndrome has long-lasting psychological effects on patients, resulting in low esteem, poor coping strategies, depression, and anxiety symptoms. Providing psychological counseling and peer support to diagnosed patients is recommended. Proper and timely psychological intervention could significantly improve a patient's outcome. Various nonsurgical and surgical methods have been suggested for treatment of MRKH syndrome. Due to the high success rate and minimal risk of complications, vaginal dilation has been proven to be the first-line therapy. Vaginoplasty is the second-line option for patients experiencing dilation failure. Uterine transplantation and gestational surrogacy are options for women with MRKH syndrome to achieve biological motherhood.

Is a Surrogate Pregnancy a High-Risk Pregnancy?

Importance

As assisted reproductive technology has advanced, there has been an increase in gestational carriers/surrogate pregnancies. Information is needed to determine if these pregnancies are high-risk pregnancies and should be managed by maternal fetal medicine or if they are not high risk and should be cared for by residency-trained obstetricians and gynecologists.

Objective

In this review of the literature, we explore whether surrogate pregnancies should be classified as high-risk pregnancies and managed by subspecialists.

Evidence Acquisition, Results

Our literature search discovered 28 relevant studies that evaluated surrogate pregnancy and pregnancy complications/outcomes. We learned that the overall risk by using artificial reproductive technology and risks for hypertension, preterm delivery, cesarean delivery, low birth weight neonate, fetal anomalies, and stillbirth did not seem to increase maternal/perinatal risk to the level where a subspecialist was required for the inclusive management of a gestational surrogate. Given that the ideal gestational carrier is healthy, has previously had a term pregnancy, has a single embryo implanted, and has had no more than 3 prior cesarean deliveries, these pregnancies should be lower-risk pregnancies.

Conclusions

We recommend that close monitoring and high index of suspicion should be maintained for complications, but care for the surrogate pregnancy can be accomplished by a residency-trained obstetrician-gynecologist.

Relevance

An uncomplicated surrogate pregnancy can be managed by a residency-trained obstetrician-gynecologist and does not need to be managed by high-risk obstetric subspecialists.

Association of multifetal gestation with obstetric and neonatal outcomes in gestational carrier pregnancies

OBJECTIVE

Multifetal gestation is more frequent among gestational carrier pregnancies than non-surrogacy IVF pregnancies. We aimed to evaluate the association between multifetal gestation and obstetric and neonatal morbidity among gestational carrier pregnancies.

METHODS

Pooled cross-sectional study of birth certificate data from gestational carrier pregnancies in Utah from 2009 to 2018. Our primary outcome was a composite of severe obstetric morbidity; secondary outcomes included cesarean delivery (CD), hypertensive disorders of pregnancy, preterm birth (PTB), and a neonatal morbidity composite. Logistic regression was utilized to compare odds of these outcomes between gestational carrier pregnancies with and without multifetal gestation.

RESULTS

A total of 361 gestational carrier pregnancies resulted in the delivery of 435 neonates during the study period. Of these, 284 were singleton pregnancies, and 77 were multifetal, a multifetal gestation rate of 21.3%. Baseline demographic characteristics did not differ between singleton and multifetal gestations. Multifetal gestation was not associated with higher rates of severe obstetric morbidity (odds ratio [OR] 1.87, 95% confidence interval [CI] 0.34-10.39). Multifetal gestation was associated with increased odds of neonatal morbidity (OR 9.49, 95% CI 5.35-15.83); PTB < 37, 34, and 32 weeks (OR 21.88, 95% CI 11.64-41.12; OR 11.67, 95% CI 5.25-25.91; OR 8.79, 95% CI 3.41-22.68); and CD (OR 4.82, 95% CI 2.81-8.27).

CONCLUSION

Severe obstetric morbidity did not differ between singleton and multifetal gestations among gestational carrier pregnancies. However, multifetal gestation was associated with increased odds of neonatal morbidity, CD, and PTB. This information may be useful when counseling prospective gestational carriers and intended parents.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome: a comprehensive update

BACKGROUND

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, also referred to as Müllerian aplasia, is a congenital disorder characterized by aplasia of the uterus and upper part of the vagina in females with normal secondary sex characteristics and a normal female karyotype (46,XX).

MAIN BODY

The diagnosis is often made during adolescence following investigations for primary amenorrhea and has an estimated prevalence of 1 in 5000 live female births. MRKH syndrome is classified as type I (isolated uterovaginal aplasia) or type II (associated with extragenital manifestations). Extragenital anomalies typically include renal, skeletal, ear, or cardiac malformations. The etiology of MRKH syndrome still remains elusive, however increasing reports of familial clustering point towards genetic causes and the use of various genomic techniques has allowed the identification of promising recurrent genetic abnormalities in some patients. The psychosexual impact of having MRKH syndrome should not be underestimated and the clinical care foremost involves thorough counselling and support in careful dialogue with the patient. Vaginal agenesis therapy is available for mature patients following therapeutical counselling and education with non-invasive vaginal dilations recommended as first-line therapy or by surgery. MRKH syndrome involves absolute uterine factor infertility and until recently, the only option for the patients to achieve biological motherhood was through gestational surrogacy, which is prohibited in most countries. However, the successful clinical trial of uterus transplantation (UTx) by a Swedish team followed by the first live-birth in September, 2014 in Gothenburg, proofed the first available fertility treatment in MRKH syndrome and UTx is now being performed in other countries around the world allowing women with MRKH syndrome to carry their own child and achieve biological motherhood.

CONCLUSION

Several advances in research across multiple disciplines have been made in the recent years and this kaleidoscopic review provides a current status of various key aspects in MRKH syndrome and provides perspectives for future research and improved clinical care.

Pregnancy and birth outcomes of single versus multiple embryo transfer in gestational surrogacy arrangements: a systematic review and meta-analysis

Multiple embryo transfer (MET) is associated with both an increased risk of multiple pregnancy and of live birth. In recent years, MET has become standard practice for most surrogacy arrangements. There is limited review of the use of MET versus single embryo transfer (SET) in surrogacy practice. The present review systematically evaluated the pregnancy outcomes of surrogacy arrangements between MET versus SET among gestational carriers. A systematic search of five computerized databases without restriction to the English language or study type was conducted to evaluate the primary outcomes: (i) clinical pregnancy; (ii) live delivery; and (iii) multiple delivery rates. The search returned 97 articles, five of which met the inclusion criteria. The results showed that clinical pregnancy (RR = 1.21, 95% CI: 1.06-1.39, n  =  5, I² = 41%), live delivery (RR = 1.29, 95% CI: 1.10-1.51, n  =  4, I² = 35%) and multiple delivery rates (RR = 1.42, 95% CI: 6.58-69.73, n  =  4, I² = 54%) were statistically significantly different in MET compared to SET. Adverse events including miscarriage, preterm birth and low birthweight were found following MET. Our findings support the existing evidence that MET results in multiple pregnancy and subsequently more adverse outcomes compared to SET. From a public health perspective, SET should be advocated as the preferred treatment for gestational carriers.

Understanding gestational surrogacy in the United States: a primer for obstetricians and gynecologists

As gestational surrogacy (a process by which intended parents contract with a woman to carry a fetus that the intended parents will raise) increases across the United States, it is imperative that obstetrician/gynecologists understand the unique nuances of caring for patients who are gestational surrogates. Gestational surrogacy offers a route to parenthood for individuals and families who may otherwise have limited options. Understanding surrogacy requires multiple ethical considerations about the potential medical and psychosocial effects on gestational surrogates as well as the families built through surrogacy. There is a dearth of research on the subject, particularly in the United States and other countries that practice compensated surrogacy. Here we seek to review the process of gestational surrogacy in the United States, including the legal landscape, current trends in gestational surrogacy use, and what is known about the medical and social effects of this process on all participants. We also aim to highlight the limitations of available data and to identify topics for future research to provide optimal evidence-based and just care for these patients.

Perceptions of Surrogacy Within the Yoruba Socio-Cultural Context of Ado-Ekiti, Nigeria

Background: Surrogacy might be a reproductive process that brings joy and fulfilment to many but it also brings with it numerous ethical and legal concerns; it raises questions about the fundamental human rights, welfare and wellbeing of women and infants especially within a context where it is barely regulated. This article examines the perception of surrogacy within the Yoruba socio-cultural context in Ado-Ekiti, Nigeria. It brings to the fore various socio-cultural concerns that questions the influence of surrogacy as a reproductive process on womanhood, motherhood and parenthood. It discusses by analysing the narratives of participants how surrogacy process is a dereliction of the sacredness and cultural sanctity of the family system, most especially in an African context.

Methods: 15 stakeholders (traditional birth attendants and gynaecologists) were engaged in an in-depth interview to unravel the challenges surrogacy might or is encountering within the socio-cultural context of Ado-Ekiti.

Results: There are various social, cultural and religious beliefs that police the reproductive sphere of the Yoruba socio-cultural group, which has grave implications on fertility treatment. These socio-cultural and religious factors do not provide a fertile ground for surrogacy to thrive within the study location. Hence, it is important that the socio-cultural framing of reproduction within this cultural context become receptive to medical reproductive solutions and innovations if at all the processes are to thrive or at least become less stigmatised.

Conclusions: The process of surrogacy is very complex and people’s attitude towards the practice is greatly influenced by their culture, religion and social belief systems about what is considered appropriate for procreation. Also, it is important to have clear-cut policy regulating surrogacy and all forms of ARTs in Nigeria, as this will protect women and infants, as well as, ensure that they are not to exposed abuse, commercialization and exploitation.

Incidence of surrogacy in the USA and Israel and implications on women's health: a quantitative comparison

PURPOSE

Gestational surrogacy (GS) has been researched in multiple qualitative studies. In contrast, quantitative aspects of the practice are conspicuously understudied. The present article assesses and compares the incidence of GS in the USA and Israel, two industrialized countries that have maintained active commercial surrogacy practice, for over two decades.

METHOD

The article is a secondary analysis of GS figures published by the Israeli Parliament's Centre for Research and Information (2018) and by the USA's Centers for Disease Control (2016) and related professional publications. Each dataset is analyzed in reference to the respective country, so as to devise local incidence scores that are then juxtaposed in inter-country comparison.

RESULTS

The incidence of GS rises steeply in both countries. Though US surrogates are contracted by local and international, heterosexual and gay, and partnered and single intended parents, the relative incidence of GS is lower in the USA than in Israel, where only local heterosexual couples could contract a gestational surrogate. An exceptionally high rate of multiple births was observed in both settings, suggesting some overlooking of professional recommendations for elective single-embryo transfer.

CONCLUSION

GS incidence appears to resemble the ratio between the countries' respective fertility rates. The paper underscores two main risks facing gestational surrogates: the risk of not conceiving and not being paid and the risk of carrying a multiple pregnancy, which is extremely prevalent in GS pregnancies, and sustaining the short- and long-term health complications that are more prevalent in such pregnancies.

Surrogacy and ethics in women with cancer

Women diagnosed with gynaecological cancer may face unwanted loss of fertility as well as all the other life-changing issues with which cancer and its treatments are associated. The decision to harvest and store gametes has to be made before commencement of treatment, and advances in these techniques have made this successful. Fertility sparing therefore must be discussed and offered at an early stage post diagnosis. Surrogacy is currently an evidence-based method of assisted reproduction, with mainly desirable outcomes for the commissioning mother, surrogate and child, without impacting on the cancer treatment and long-term survival. Surrogacy is therefore ethical as long as the autonomous rights of both the commissioning mother and gestational carrier are equally observed, they both have equal legal protection and due attention is paid to the short- and long-term welfare of any resulting offspring.
