Psychosocial outcomes of children born via embryo donation

STUDY QUESTION

What are parents' perceptions of their relationships with and the psychosocial adjustments of their children who are born via embryo donation?

SUMMARY ANSWER

Families created through embryo donation have well-adjusted parent-child relationships and reassuring child psychosocial outcomes.

WHAT IS KNOWN ALREADY

Embryo donation is an effective and growing form of third-party reproduction, but there is limited research in this field. Prior studies suggest that families created through gamete donation function well regarding parent-child relationship quality and child behavioral and socioemotional adjustment.

STUDY DESIGN, SIZE, DURATION

This is a cross-sectional survey study with 187 total participants.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Parents of children born via embryo donation were recruited nationally by contacting all embryo donation programs registered with the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) as well as medically directed embryo donation or 'embryo adoption' centers. Participants completed three online Qualtrics questionnaires. The first was a survey including 33 questions on demographics, the procurement process, and self-reported obstetric outcomes. Participants also completed two standardized measures assessing children's behavior and parents' adjustment to parenthood: the Strengths and Difficulties Questionnaire (SDQ) and the Parental Acceptance-Rejection Questionnaire (PARQ). Scoring of the SDQ and PARQ was totaled and compared to standardized values (SDQ) or previously published results on other forms of gamete donation (PARQ), such as oocyte donation and sperm donation.

MAIN RESULTS AND THE ROLE OF CHANCE

On the SDQ (n = 46), the average total difficulties scores by age were: 8.2 ± 0.98 for ages 2-4, 7.6 ± 0.93 for ages 5-10, and 3.5 ± 0.77 for ages 11-17; this is compared to the normal reported range of 0-13, which indicates that clinically significant psychosocial problems are unlikely. Across all ages and individual categories (emotional symptoms, conduct problem, hyperactivity, peer problem, prosocial), scores on the SDQ were within the normal ranges. The average PARQ score (n = 70) for all respondents was 27.5 ± 1.18 (range: 24-96), suggesting perceived parental acceptance.

LIMITATIONS, REASONS FOR CAUTION

Because this study was cross-sectional, it could not capture familial relationships over time. This survey-based study design allows for potential selection bias (parents of well-adjusted children may be more likely to participate). Additionally, the overall sample size is relatively small; however, it remains one of the largest published to date. Another significant limitation to this study is the lack of generalizability: most participants were recruited from private, faith-based, embryo donation programs who are demographically similar.

WIDER IMPLICATIONS OF THE FINDINGS

Though embryo donation is an established form of third-party reproduction, it is significantly less robustly studied compared to other forms of gamete donation (oocyte or sperm donation). This study provides a larger data set with a more expanded age range of children compared to the limited number of previously published studies. Furthermore, these findings indicate a high parental disclosure rate with respect to the use of embryo donation which contrasts previous findings.

Anti-Müllerian Hormone Level Decline in Patients Undergoing Hysterectomy With and Without Oophorectomy Compared With Natural Menopause

OBJECTIVE

To evaluate the relationship between hysterectomy with and without ovarian conservation and the onset of ovarian failure using anti-müllerian hormone (AMH) levels and imputed final menstrual period (FMP).

METHODS

A total of 1,428 women with an observed FMP and 232 women who underwent hysterectomy (159 with bilateral salpingo-oophorectomy [BSO], 13 with one ovary conserved, and 60 with both ovaries conserved) and who had serial AMH measurements were included from SWAN (The Study of Women's Health Across the Nation), a multi-ethnic, multi-site, community-based study. Anti-müllerian hormone levels were sampled annually with at least one presurgery or pre-FMP measurement at least one postsurgery or post-FMP measurement. Surgery-related differences in patterns of AMH levels with respect to surgery date or FMP were estimated using piecewise linear mixed modeling; differences in age at first undetectable AMH level were estimated using survival analyses.

RESULTS

Patients with conservation of one or both ovaries or natural menopause demonstrated similar patterns of decline in AMH levels when anchored to surgery or FMP. Patients with hysterectomy (all types) had a later counterfactual FMP (52.9±0.2 SEM) compared with the observed FMP in those with natural menopause (52.1±0.1 years, P =.002). Those undergoing BSO had an immediate reduction in AMH level to undetectable after surgery.

CONCLUSION

Hysterectomy does not lead to a more rapid decline in AMH levels postoperatively compared with natural menopause. Patients undergoing BSO have a rapid loss of AMH, consistent with complete removal of the ovaries. These data suggest that hysterectomy as currently performed does not compromise ovarian reserve.

On the shoulders of giants: perspectives in minimally invasive reproductive surgery

The purpose of this video is to illustrate the evolution of minimally invasive surgery from the perspectives of several pioneering surgeons in the field of reproductive surgery who, among others, were present during its nascence and exponential growth. Interviews were conducted with five reproductive surgeons who had foundational roles in the innovation of operative laparoscopy and hysteroscopy. Surgeons interviewed include Drs. Victor Gomel, Togas Tulandi, Stephen Corson, Jacques Donnez, and Camran Nezhat. The interviews were conducted using standardized questions and recorded, edited, and grouped both thematically and in sequence to develop an illustration of their perspectives. A diverse array of reproductive surgeons has been instrumental in establishing minimally invasive surgery as a safe and effective means of diagnosing and treating patients with infertility. The transition from laparotomy to laparoscopy consistently has had distinct challenges for each but ultimately led to significant advances in surgical management and improvement in outcomes for patients with infertility and chronic pelvic pain. Through structured interviews from some of our surgical pioneers, they not only recognize their predecessors and contemporaries but also teach us valuable lessons about our history, sparking innovation, and newer surgical applications of reproductive surgery in reproductive endocrinology and infertility practice.

Preimplantation genetic testing for aneuploidy in uterus transplant patients

Uterus transplantation is an emerging treatment for uterine factor infertility. In vitro fertilization with cryopreservation of embryos prior is required before a patient can be listed for transplant. Whether or not to perform universal preimplantation genetic testing for aneuploidy should be addressed by centers considering a uterus transplant program. The advantages and disadvantages of preimplantation genetic testing for aneuploidy in this unique population are presented. The available literature is reviewed to determine the utility of preimplantation genetic testing for aneuploidy in uterus transplantation protocols. Theoretical benefits of preimplantation genetic testing for aneuploidy include decreased time to pregnancy in a population that benefits from minimization of exposure to immunosuppressive agents and decreased chance of spontaneous abortion requiring a dilation and curettage. Drawbacks include increased cost per in vitro fertilization cycle, increased number of required in vitro fertilization cycles to achieve a suitable number of embryos prior to listing for transplant, and a questionable benefit to live birth rate in younger patients. Thoughtful consideration of whether or not to use preimplantation genetic testing for aneuploidy is necessary in uterus transplant trials. Age is likely a primary factor that can be useful in determining which uterus transplant recipients benefit from preimplantation genetic testing for aneuploidy.

Diverse Approaches to Ovarian Tissue Cryopreservation Have Equivalent Outcomes in Markers of Tissue Viability

Ovarian tissue cryopreservation (OTC) is an accepted method of fertility preservation. However, OTC is not standardized and many variations exist in the freezing strategy, tissue processing, and surgical approach. In this pilot study, we used a sheep model to compare slow freezing versus vitrification techniques, as well as the feasibility of processing ovarian tissue into a hyaluronan suspension of small ovarian units. Twelve ovaries were harvested from six female ewes. Paired tissues from each animal were assigned to different treatments and underwent freezing, thawing, autotransplantation, and second-look surgery, for a total of 18 surgical procedures and 3 measured time points. Treatments included whole tissue strips versus gel suspension and slow freezing versus vitrification. At each of the time points, tissue viability was measured by immunohistochemical analysis of CD31 and cleaved caspase-3 (CCASP3). CD31 and CCASP3 expression levels were equivalent between slow freezing and vitrification, and between whole ovarian tissue strips and gel suspension of fragmented ovarian tissue, at all time points. These preliminary data using a sheep model suggest that ovarian tissue is robust and likely to be minimally affected by aggressive fragmentation using a hyaluronan suspension. Furthermore, we provide evidence in support of vitrification as a viable option in OTC. Hyaluronan suspension of ovarian cortical fragments is novel and may represent a desirable method for reimplantation of frozen-thawed ovarian tissue in patients where occult malignant cells are a concern.

60S acidic ribosomal protein P1 (RPLP1) is elevated in human endometriotic tissue and in a murine model of endometriosis and is essential for endometriotic epithelial cell survival in vitro

Endometriosis is a female disease which is defined as the presence of ectopic endometrial tissue and is dependent on estrogen for its survival in these ectopic locations. Expression of the ribosomal protein large P1 (RPLP1) is associated with cell proliferation and invasion in several pathologies, but a role in the pathophysiology of endometriosis has not been explored. In this study, we aimed to evaluate the expression and function of RPLP1 with respect to endometriosis pathophysiology. RPLP1 protein was localised by immunohistochemistry (IHC) in eutopic and ectopic tissue from 28 subjects with confirmed endometriosis and from 20 women without signs or symptoms of the disease, while transcript levels were evaluated by qRT-PCR in 77 endometriotic lesions and 55 matched eutopic endometrial biopsies, and protein expression was evaluated using western blotting in 20 of these matched samples. To evaluate the mechanism for enhanced lesion expression of RPLP1, an experimental murine model of endometriosis was used and RPLP1 expression was localized using IHC. In vitro studies using an endometriosis cell line coupled with shRNA knockdown was used to demonstrate its role in cell survival. Expression of RPLP1 mRNA and protein were significantly higher in ectopic lesion tissue compared to paired eutopic endometrium and immunohistochemical localisation revealed predominant localisation to epithelial cells. This pattern of lesion RPLP1 was recapitulated in mice with experimentally induced endometriosis. Stable knockdown of RPLP1 protein resulted in a significant decrease in cell survival in vitro. These studies reveal that RPLP1 is associated with cell proliferation and/or survival and may play a role in the pathophysiology of endometriosis.

Excision versus Ablation for Management of Minimal to Mild Endometriosis: A Systematic Review and Meta-analysis

OBJECTIVE

The aim of this systematic review and meta-analysis was to perform an updated analysis of the literature in regard to the surgical management of minimal to mild endometriosis. This study evaluated women of reproductive age with superficial endometriosis to determine if the results of surgical excision compared with those of ablation in improved pain scores postoperatively.

DATA SOURCES

The following databases were searched from inception to May 2020 for relevant studies: Cochrane Central Register of Controlled Trials, PubMed (MEDLINE), Ovid (MEDLINE), Scopus, and Web of Science.

METHODS OF STUDY SELECTION

From our literature search, a total of 2633 articles were identified and screened. Ultimately, 4 randomized controlled trials were selected and included in our systematic review. The combined total number of subjects was 346 from these 4 studies, with sample sizes ranging from 24 to 170 participants. Data from 3 of the included studies were able to be compared and analyzed for a meta-analysis. The primary outcome was reduction in the visual analog scale (VAS) score for endometriosis-associated pain (dysmenorrhea, dyschezia, and dyspareunia), with follow-up time ranging from 6 to 60 months postoperatively.

TABULATION, INTEGRATION, AND RESULTS

Data extracted from each study included the mean reduction in the VAS score from baseline. A random-effects model was used owing to significant heterogeneity across the studies. Statistical analyses were performed using Review Manager 5.3 software (Cochrane Collaboration, London, United Kingdom). The meta-analyses showed no significant differences between the excision and ablation groups in the mean reduction in VAS scores from baseline to 12 months postoperatively for dysmenorrhea (mean difference [MD] -0.03; 95% confidence interval [CI], -1.27 to 1.22; p = .97), dyschezia (MD 0.46; 95% CI, -1.09 to 2.02; p = .56), and dyspareunia (MD 0.10; 95% CI, -2.36 to 2.56; p = .94). In addition, there were no significant differences between the excision and ablation groups in mean VAS scores at the 12-month follow-up and beyond for dysmenorrhea (MD -0.11; 95% CI, -2.14 to 1.93; p = .92), dyschezia (MD 0.01; 95% CI, -0.70 to 0.72; p = .99), and dyspareunia (MD 0.34; 95% CI, -1.61 to 2.30; p = .73).

CONCLUSION

On the basis of the data from our systematic review and pooled meta-analysis, no significant difference between laparoscopic excision and ablation was noted in regard to improving pain from minimal to mild endometriosis. However, to make definitive conclusions on this topic, larger randomized controlled trials are needed with longer follow-up.

Guidelines for standardized nomenclature and reporting in uterus transplantation: An opinion from the United States Uterus Transplant Consortium

Uterus transplantation is a nascent but growing field. To support this growth, the United States Uterus Transplant Consortium proposes guidelines for nomenclature related to operative technique, vascular anatomy, and donor, recipient, and offspring outcomes. In terms of anatomy, the group recommends reporting donor arterial inflow and recipient anastomotic site delivering inflow to the graft and offers standardization of the names for the 4 veins originating from the uterus because of current inconsistency in this particular nomenclature. Seven progressive stages with milestones of success are defined for reporting on uterus transplantation outcomes: (1) technical, (2) menstruation, (3) embryo implantation, (4) pregnancy, (5) delivery, (6) graft removal, and (7) long-term follow-up. The 3 primary metrics for success are recipient survival (as reported for other organ transplant recipients), graft survival, and uterus transplant live birth rate (defined as live birth per transplanted recipient). A number of secondary outcomes should also be reported, most of which capture stage-specific milestones, as well as data on graft failure. Outcome metrics for living donors include patient survival, survival free of operative intervention, and data on complications and hospitalizations. Finally, we make specific recommendations on follow-up for offspring born from uterine grafts, which includes specialty surveillance as well as collection and reporting of routine pediatric outcomes. The goal of standardization in reporting is to create consistency and improve the quality of evidence available on the efficacy and value of the procedure.

First birth from a deceased donor uterus in the United States: from severe graft rejection to successful cesarean delivery

Uterus transplantation is the only known potential treatment for absolute uterine factor infertility. It offers a unique setting for the investigation of immunologic adaptations of pregnancy in the context of the pharmacologic-induced tolerance of solid organ transplants, thus providing valuable insights into the early maternal-fetal interface. Until recently, all live births resulting from uterus transplantation involved living donors, with only 1 prior birth from a deceased donor. The Cleveland Clinic clinical trial of uterus transplantation opened in 2015. In 2017, a 35 year old woman with congenital absence of the uterus was matched to a 24 year old parous deceased brain-dead donor. Transplantation of the uterus was performed with vaginal anastomosis and vascular anastomoses bilaterally from internal iliac vessels of the donor to the external iliac vessels of the recipient. Induction and maintenance immunosuppression were achieved and subsequently modified in anticipation of pregnancy 6 months after transplant. Prior to planned embryo transfer, ectocervical biopsy revealed ulceration and a significant diffuse, plasma cell-rich mixed inflammatory cell infiltrate, with histology interpreted as grade 3 rejection suspicious for an antibody-mediated component. Aggressive immunosuppressive regimen targeting both cellular and humoral rejection was initiated. After 3 months of treatment, there was no histologic evidence of rejection, and after 3 months from complete clearance of rejection, an uneventful embryo transfer was performed and a pregnancy was established. At 21 weeks, central placenta previa with accreta was diagnosed. A healthy neonate was delivered by cesarean hysterectomy at 34 weeks' gestation. In summary, this paper highlights the first live birth in North America resulting from a deceased donor uterus transplant. This achievement underscores the capacity of the transplanted uterus to recover from a severe, prolonged rejection and yet produce a viable neonate. This is the first delivery from our ongoing clinical trial in uterus transplantation, including the first reported incidence of severe mixed cellular/humoral rejection as well as the first reported placenta accreta.

Evolving ethical issues with advances in uterus transplantation

While uterus transplantation was once considered only a theoretical possibility for patients with uterine factor infertility, researchers have now developed methods of transplantation that have led to successful pregnancies with multiple children born to date. Because of the unique and significant nature of this type of research, it has been undertaken with collaboration not only with scientists and physicians but also with bioethicists, who paved the initial path for research of uterus transplantation to take place. As the science of uterus transplantation continues to advance, so too must the public dialogue among obstetrician/gynecologists, transplant surgeons, bioethicists, and other key stakeholders in defining the continued direction of research in addition to planning for the clinical implementation of uterus transplantation as a therapeutic option. Given the rapid advances in this field, the time has come to revisit the fundamental questions raised at the inception of uterus transplantation and, looking forward, determine the future of this approach given emerging data on the procedure's impact on individuals, families, and society.

Infertility: A practical framework

Fertility concerns are common in men and women of reproductive age, and primary care physicians are often the first line in addressing, assessing, and referring these patients. This article reviews the answers to questions patients often ask, and outlines a practical framework for the evaluation and management of the infertile couple. Up-to-date information is provided on available assisted reproductive technologies for the infertile couple, as well as preserving fertility in the setting of aging-related changes in the female reproductive system.

Prioritizing Women's Health in Germline Editing Research

Although women are inextricably involved in the study of germline editing, their interests have not been significantly represented in debates about the evolution of genome editing technology. Discussions have taken place about effects of germline editing on women as parents and members of families, but key discussions about women's health and well-being as patients and subjects are lacking. This neglect is due in part to restrictions on uterine transfer of modified human embryos, a boundary that has now been crossed. As a result, only scant discussion has taken place about safeguards needed to ensure that women who participate in germline modification research are not exposed to disproportionate risk in exchange for benefits they might expect for future offspring. This omission sets the stage for serious ethical implications for women and their families.

New Frontier: Role of the Radiologist in Uterine Transplantation

Uterine transplantation (UT) is a novel treatment for absolute uterine factor infertility (AUFI) that is currently being performed under experimental protocols in multiple medical centers worldwide. At the time of this publication, there have been at least 10 live births by women with a transplanted uterus. As successful outcomes from this innovative procedure increase, it is likely that more centers will perform UT. Imaging is performed in multiple steps of the UT process, including preoperative imaging of potential donors and recipients, posttransplant surveillance, and monitoring of pregnancy. Fetal imaging is performed by maternal-fetal medicine professionals, but most imaging examinations in UT are performed by radiologists. Given the significant role of imaging in this groundbreaking surgery, radiologists must be familiar with the causes of AUFI and the role of imaging in establishing this diagnosis. Radiologists working in medical centers where UT is performed should understand the role of imaging in preoperative planning and postoperative surveillance. While data regarding complications of UT are preliminary at best, radiologists must be aware of the risk of vascular compromise and graft failure and their imaging features. The authors provide a brief history of UT and define the radiologist's role in pre- and postoperative imaging assessments.^©RSNA, 2019.

Framing the diagnosis and treatment of absolute uterine factor infertility: Insights from in-depth interviews with uterus transplant trial participants

BACKGROUND

Despite procedural innovations and increasing numbers of uterus transplant attempts worldwide, the perspectives of uterus transplant (UTx) trial participants are lacking.

METHODS

We conducted a mixed-methods study with women with absolute uterine factor infertility (AUFI). Participants included women who had previously contacted the Cleveland Clinic regarding the Uterine Transplant Trial and met the initial eligibility criteria for participation. In-depth interviews were conducted in conjunction with FertiQoL, a validated and widely used tool to measure the impact of infertility on the quality of life of infertility patients.

RESULTS

All (n = 19) rated their overall health as good; some experienced grief and social isolation. AUFI is a life-framing experience that influences acceptance by family, partners, peers, and one's self. UTx is a means to gain control of reproductive autonomy. UTx allows family-building and the ability to play an active role in prenatal health and well-being. Establishing and maintaining a supportive relationship is a key issue of AUFI and when considering UTx. Risks of UTx are perceived relative to risks to self/child/family posed by adoption/surrogacy. Participants had no overall preference regarding living or deceased donor.

CONCLUSIONS

The ways in which women with AUFI conceptualize this condition in their lives and choices around UTx and participating in a study of the procedure are multifaceted and textured. These perspectives are critical to understanding its ethical, legal, and social implications.
