A View from the past into our collective future: the oncofertility consortium vision statement

Purpose

Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium.

Methods

The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-of-life issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process.

Results

This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity.

Conclusion

The goals are to continually integrate the best science in the service of the needs of patients and build a community of care that is ready for the challenges of the field in the future.

Patient-centered elective egg freezing: a binational qualitative study of best practices for women's quality of care

PURPOSE

How can elective egg freezing (EEF) be made patient centered? This study asked women to reflect on their experiences of EEF, which included their insights and recommendations on the optimal delivery of patient-centered care.

METHODS

In this binational, qualitative study, 150 women (114 in the USA, 36 in Israel) who had completed at least one cycle of EEF were recruited from four American IVF clinics (two academic, two private) and three in Israel (one academic, two private) over a two-year period (June 2014-August 2016). Women who volunteered for the study were interviewed by two medical anthropologists. Interviews were audio recorded, transcribed, and entered into a qualitative data management program (Dedoose) for analysis.

RESULTS

The majority (85%) of women were without partners at the time of EEF, and thus were undertaking EEF alone in mostly couples-oriented IVF clinics. Following the conceptual framework known as "patient-centered infertility care," we identified two broad categories and eleven specific dimensions of patient-centered EEF care, including (1) system factors: information, competence of clinic and staff, coordination and integration, accessibility, physical comfort, continuity and transition, and cost and (2) human factors: attitude and relationship with staff, communication, patient involvement and privacy, and emotional support. Cost was a unique factor of importance in both countries, despite their different healthcare delivery systems.

CONCLUSIONS

Single women who are pursuing EEF alone in the mostly couples-oriented world of IVF have distinct and multifaceted needs. IVF clinics should strive to make best practices for patient-centered EEF care a high priority.

The National Physicians Cooperative: transforming fertility management in the cancer setting and beyond

Once unimaginable, fertility management is now a nationally established part of cancer care in institutions, from academic centers to community hospitals to private practices. Over the last two decades, advances in medicine and reproductive science have made it possible for men, women and children to be connected with an oncofertility specialist or offered fertility preservation soon after a cancer diagnosis. The Oncofertility Consortium's National Physicians Cooperative is a large-scale effort to engage physicians across disciplines – oncology, urology, obstetrics and gynecology, reproductive endocrinology, and behavioral health – in clinical and research activities to enable significant progress in providing fertility preservation options to children and adults. Here, we review the structure and function of the National Physicians Cooperative and identify next steps.

Ten pathways to elective egg freezing: a binational analysis

PURPOSE

What are the specific pathways that lead women to freeze their eggs? In this binational study, women were asked directly about the life circumstances that led them on the path to elective egg freezing (EEF).

METHODS

From June 2014 to August 2016, 150 women (114 in the USA, 36 in Israel) who had completed at least 1 cycle of EEF were interviewed by two medical anthropologists. Study participants were recruited through four American IVF clinics (two academic, two private) and three in Israel (one academic, two private). Interviews were audio-recorded, transcribed verbatim, and entered into a qualitative data management program (Dedoose) for analysis.

RESULTS

The majority (85%) of women in the study were without partners, while 15% had partners at the time of EEF. Six pathways to EEF were found among women without partners (being single, divorced, broken up, deployed overseas, single mother, career planner), with career planning being the least common pathway to EEF. Among women with partners, four pathways to EEF were found (relationship too new or uncertain, partner not ready to have children, partner refusing to have children, or partner having multiple partners). With only one exception, the pathways and their frequencies were similar in both countries.

CONCLUSIONS

Partnership problems, not career planning, lead most women on pathways to EEF. These pathways should be studied in a variety of national settings, and fertility clinics should offer patient-centered care for single women pursuing EEF in the couples-oriented world of IVF.

Euploidy in relation to blastocyst sex and morphology

PURPOSE

The objective of our study is to assess the relationship of embryo ploidy status in relation to embryo sex, morphological characteristics, and transfer parameters.

METHODS

This is a retrospective cohort study at an academic medical center of patients who underwent in vitro fertilization with preimplantation genetic screening (PGS) from 2010 to 2015. Embryos were screened with 24-chromosome preimplantation genetic screening with day 5/6 trophectoderm biopsy. We investigated embryo euploidy in relation to morphology (expansion, inner cell mass, trophectoderm), embryo sex, biopsy day, and blastocyst cohort size. We used multivariate logistic regression to calculate odds ratios of euploidy in relation to these parameters.

RESULTS

A total of 1559 embryos from 316 cycles and 233 patients (mean maternal age = 37.8 ± 4.2 years) were included in the analysis. Six hundred and twenty-eight blastocysts (40.3%) were found to be euploid. Expansion (p < 0.001), inner cell mass (ICM) (p < 0.01), and trophectoderm grade (p < 0.001) were significantly associated with embryo ploidy in bivariate models controlling for maternal age, while embryo sex, biopsy day, and blastocyst cohort size were not associated with embryo ploidy. In a multivariate model, we found that maternal age (p < 0.001), higher grade of expansion (p < 0.01), and better quality trophectoderm (p < 0.001 for A compared to C grade) remained significantly associated with increased embryo euploidy, but ICM grade was no longer significant. Embryo sex was not associated with ploidy status, though male embryos were found to be associated with higher trophectoderm scores (p < 0.02).

CONCLUSIONS

This is the largest study to date to investigate PGS-tested embryo sex and ploidy status. While maternal age and some morphological parameters (expansion, trophectoderm grade) are associated with euploidy in our cohort, other parameters such as embryo sex, biopsy day, and cohort size are not. Though embryo sex was not associated with euploidy, male embryos were found to be associated with higher trophectoderm grades. Additional investigation in larger studies is warranted.

Cross border reproductive care (CBRC): a growing global phenomenon with multidimensional implications (a systematic and critical review)

PURPOSE

Many people travel abroad to access fertility treatments. This growing phenomenon is known as cross border reproductive care (CBRC) or fertility tourism. Due to its complex nature and implications worldwide, CBRC has become an emerging dilemma deserving more attention on the global healthcare agenda.

METHODS

According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the literature was performed for all relevant full-text articles published in PubMed in English during the past 18 years to explore CBRC phenomenon in the new millennium.

RESULTS

Little is known about the accurate magnitude and scope of CBRC around the globe. In this systematic and critical review, we identify three major dimensions of CBRC: legal, economic, and ethical. We analyze each of these dimensions from clinical and practical perspectives.

CONCLUSION

CBRC is a growing reality worldwide with potential benefits and risks. Therefore, it is very crucial to regulate the global market of CBRC on legal, economic, and ethical bases in order to increase harmonization and reduce any forms of exploitation. Establishment of accurate international statistics and a global registry will help diminish the current information gap surrounding the CBRC phenomenon.

Medical egg freezing: How cost and lack of insurance cover impact women and their families

Medical egg freezing (MEF) is being recommended increasingly for women at risk of losing their reproductive ability due to cancer chemotherapy or other fertility-threatening medical conditions. This first, binational, ethnographic study of women who had undergone MEF sought to explore women's experiences under two different funding systems: (i) the USA, where the cost of MEF is rarely covered by private or state health insurance; and (ii) Israel, where the cost of MEF is covered by national health insurance. Women were recruited from four American and two Israeli in-vitro fertilization clinics where MEF is offered. In-depth, semi-structured interviews were conducted with 45 women (33 Americans, 12 Israelis) who had completed at least one cycle of MEF. All of the Israeli women had cancer diagnoses, but were not faced with the additional burden of funding an MEF cycle. In marked contrast, the American women - 23 with cancer diagnoses and 10 with other fertility-threatening medical conditions - struggled, along with their families, to 'piece together' MEF funding, which added significant financial pressure to an already stressful situation. Given the high priority that both American and Israeli women in this study placed on survival and future motherhood, it is suggested that insurance funding for MEF should be mandated in the USA, as it is in Israel. This article concludes by describing new state legislative efforts in this regard.

Medical egg freezing: the importance of a patient-centered approach to fertility preservation

PURPOSE

This binational qualitative study of medical egg freezing (MEF) examined women's motivations and experiences, including their perceived needs for patient-centered care in the midst of fertility- and life-threatening diagnoses.

METHODS

Forty-five women who had undertaken MEF were interviewed in the USA (33 women) and in Israel (12 women) between June 2014 and August 2016. Interviews lasted approximately 1 h and were conducted by two senior medical anthropologists, one in each country. Women were recruited from four American IVF clinics (two academic, two private) and two Israeli clinics (both academic) where MEF is being offered to cancer patients and women with other fertility-threatening medical conditions.

RESULTS

Women who undertake MEF view their fertility and future motherhood as important components of their identities and recovery and, thus, are grateful for the opportunity to pursue fertility preservation. However, women who undergo MEF have special needs, given that they tend to be a "vulnerable" population of young (age < 30), unmarried, resource-constrained women, who are facing not only fertility loss but also the "double jeopardy" of cancer. Through in-depth, qualitative interviews, these women's MEF stories reveal 10 dimensions of care important to fertility preservation, including five "system factors" (information, coordination and integration, accessibility, physical comfort, cost) and five "human factors" (adolescent issues, male partner involvement, family involvement, egg disposition decisions, emotional support). Together, these dimensions of care constitute an important framework that can be best described as "patient-centered MEF."

CONCLUSIONS

Women pursuing MEF have special medical needs and concerns, which require particular forms of patient-centered care. This study outlines 10 dimensions of patient-centered fertility preservation that are appropriate for MEF patients. This approach may help IVF clinics to be better prepared for delivering top-quality care to mostly young, single women facing the daunting prospect of fertility loss and life-threatening medical diagnoses.

Results of a pilot study in the U.S. and Vietnam to assess the utility and acceptability of a multi-level pregnancy test (MLPT) for home monitoring of hCG trends after assisted reproduction

Background

To evaluate the utility and acceptability of using multi-level pregnancy tests (MLPTs) at home to monitor hCG trends following assisted reproductive technology (ART).

Methods

One hundred and four women presenting for ART at either Stanford Medicine Fertility and Reproductive Health Clinic (Stanford, CA) or Hung Vuong Hospital (Ho Chi Minh City, Vietnam) participated in this pilot study. Women were asked to perform the MLPT at home, primarily on days when they were also scheduled to receive standard clinic-based serum hCG testing. These tests were administered up to 6 times over the 6-week period following embryo transfer or intrauterine insemination (IUI). Concordance of serial hCG readings for each time point was assessed by comparing trends in urine MLPT results with trends in serum hCG. Stable or increasing hCG level was interpreted as an indication of a progressing pregnancy, while a declining hCG was interpreted as a lack of established or progressing pregnancy. At study end, all participants were asked about the acceptability and convenience of using the MLPT at home for monitoring hCG trends following ART.

Results

Data from both urine and serum testing are available for 156 of 179 clinic visits (87.2%). There was high concordance of serial trend results between the two types of tests: among the 156 sets of serum and urine hCG data points, 150 (96.2%) showed a matching trend in hCG pattern and 6 (3.8%) resulted in a discordant trend. Seventy-three percent of women reported being satisfied or very satisfied with using the MLPTs at home. Almost all (96.6%) said that the MLPT was easy or very easy to use.

Conclusion

The MLPT offers women and health care providers a client-friendly diagnostic tool to detect very early pregnancy and monitor its progress.

Trial registration

This study was registered on clinicaltrials.gov as NCT01846403 (May 1, 2013), and NCT01919502 (August 5, 2013).

Comparison of epigenetic mediator expression and function in mouse and human embryonic blastomeres

A map of human embryo development that combines imaging, molecular, genetic and epigenetic data for comparisons to other species and across pathologies would be greatly beneficial for basic science and clinical applications. Here, we compared mRNA and protein expression of key mediators of DNA methylation and histone modifications between mouse and human embryos, embryos from fertile/infertile couples, and following growth factor supplementation. We observed that individual mouse and human embryos are characterized by similarities and distinct differences in DNA methylation and histone modification patterns especially at the single-cell level. In particular, while mouse embryos first exhibited sub-compartmentalization of different histone modifications between blastomeres at the morula stage and cell sub-populations in blastocysts, differential histone modification expression was detected between blastomeres earlier in human embryos at the four- to eight-cell stage. Likewise, differences in epigenetic mediator expression were also observed between embryos from fertile and infertile couples, which were largely equalized in response to growth factor supplementation, suggesting that select growth factors might prevent alterations in epigenetic profiles during prolonged embryo culture. Finally, we determined that reduced expression via morpholino technologies of a single histone-modifying enzyme, Rps6ka4/Msk2, resulted in cleavage-stage arrest as assessed by time-lapse imaging and was associated with aneuploidy generation. Taken together, data document differences in epigenetic patterns between species with implications for fertility and suggest functional roles for individual epigenetic factors during pre-implantation development.

Fertility issues in cancer survivorship

Breakthroughs in cancer diagnosis and treatment have led to dramatic improvements in survival and the need to focus on survivorship issues. Chemotherapy and radiotherapy can be gonadotoxic, resulting in impaired fertility. Techniques to help cancer survivors reproduce have been improving over the past decade. Discussion of the changes to a patient's reproductive health after cancer treatment is essential to providing comprehensive quality care. The purpose of this review is to aid in pre- and posttreatment counseling, focusing on fertility preservation and other strategies that may mitigate risks to the patient's reproductive, sexual, and overall health.

Pregnancy During Recovery from Hematopoietic Stem Cell Transplant for Mycosis Fungoides

We report a case of spontaneous pregnancy with subsequent full-term live birth following hematopoietic stem cell transplantation (HSCT) for mycosis fungoides in a 24-year-old nulligravida with 4 years of prior infertility due to primary ovarian insufficiency. Four months post-transplant, the patient was found to be 10 weeks pregnant. Her pregnancy was complicated by first trimester fetal exposure to mycophenolate mofetil (pregnancy category D), delayed-onset acute gastrointestinal graft-versus-host disease, and multiple systemic infections. This report highlights the importance of discussing potential fertility outcomes in patients undergoing HSCT, including the necessity for adequate contraception post-transplant, even in the setting of previous infertility.

Stress and anxiety scores in first and repeat IVF cycles: a pilot study

Background

The role of stress in reproduction, particularly during treatment for infertility, has been of considerable interest; however, few studies have objectively measured stress and anxiety over the course of the IVF cycle or compared the experience of first-time and repeat patients.

Methods

This prospective cohort pilot study enrolled 44 women undergoing IVF at a university-based clinic to complete the State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS) and Infertility Self-Efficacy Scale (ISES) at three time points prior to ovarian stimulation (T1), one day prior to oocyte retrieval (T2), and 5–7 days post embryo transfer (T3).

Results

Mean STAI State scores were significantly elevated at all three time points (p<0.01). STAI State and PSS mean values did not change over time and did not differ in first-time vs. repeat patients. Self-efficacy (ISES) scores declined over time, with a greater decline for repeat patients. Of the 36 women who completed a cycle, 15 achieved clinical pregnancy. Using logistic regression modeling, all scores at T2 were correlated with pregnancy outcome with lower scores on the STAI State and PSS and higher scores on the ISES associated with higher pregnancy rates.

Conclusions

Stress and anxiety levels remained elevated across all cycles. Women with lower stress and anxiety levels on the day prior to oocyte retrieval had a higher pregnancy rate. These results emphasize the need to investigate stress reduction modalities throughout the IVF cycle.

Global alteration in gene expression profiles of deciduas from women with idiopathic recurrent pregnancy loss

Recurrent pregnancy loss (RPL) occurs in ∼5% of women. However, the etiology is still poorly understood. Defects in decidualization of the endometrium during early pregnancy contribute to several pregnancy complications, such as pre-eclampsia and intrauterine growth restriction (IUGR), and are believed to be important in the pathogenesis of idiopathic RPL. We performed microarray analysis to identify gene expression alterations in the deciduas of idiopathic RPL patients. Control patients had one antecedent term delivery, but were undergoing dilation and curettage for current aneuploid miscarriage. Gene expression differences were evaluated using both pathway and gene ontology (GO) analysis. Selected genes were validated using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). A total of 155 genes were found to be significantly dysregulated in the deciduas of RPL patients (>2-fold change, P < 0.05), with 22 genes up-regulated and 133 genes down-regulated. GO analysis linked a large percentage of genes to discrete biological functions, including immune response (23%), cell signaling (18%) and cell invasion (17.1%), and pathway analysis revealed consistent changes in both the interleukin 1 (IL-1) and IL-8 pathways. All genes in the IL-8 pathway were up-regulated while genes in the IL-1 pathway were down-regulated. Although both pathways can promote inflammation, IL-1 pathway activity is important for normal implantation. Additionally, genes known to be critical for degradation of the extracellular matrix, including matrix metalloproteinase 26 and serine peptidase inhibitor Kazal-type 1, were also highly up-regulated. In this first microarray approach to decidual gene expression in RPL patients, our data suggest that dysregulation of genes associated with cell invasion and immunity may contribute significantly to idiopathic recurrent miscarriage.

Age-Related Success with Elective Single versus Double Blastocyst Transfer

Background. Although the optimal outcome of assisted reproductive technology (ART) is a healthy singleton pregnancy, the rate of twin gestation from ART in women over the age of 35 is persistently high. Methods/Findings. We compared clinical pregnancy rates (PRs), ongoing pregnancy/live birth rates, and multiple gestation rates (MGRs) in 108 women who chose elective single blastocyst transfer (eSBT) to 415 women who chose elective double blastocyst transfer (eDBT) at a hospital-based IVF center. There was no significant difference in PR between eSBT and eDBT (57.4% versus 50.2%, P = 0.47) nor between eSBT and eDBT within each age group: <35, 35–37, 38–40, and >40. The risk of multiple gestations, however, was greatly increased between eSBT and eDBT (1.6 versus 32.4%, P < 0.00005), and this difference did not vary across age groups. Conclusion(s). Women undergoing eDBT are at uniformly high risk of multiple gestation regardless of age. eSBT appears to significantly lower the risk of multiple gestation without compromising PR.

Mood disorders in oocyte donor candidates: brief report and implications for future research

BACKGROUND IVF, using donor oocytes, has become increasingly common. The donation procedure carries psychiatric risks, including depression, anxiety and rarely, psychosis, and this risk increases when there is a past history of psychiatric illness. We report on the psychiatric status, at intake assessment, of a group of candidate oocyte donors. METHODS The authors reviewed clinical records of 63 women continuously presenting to a University medical center for psychiatric evaluation as part of the screening process for oocyte donation. A board certified psychiatrist administered a structured clinical interview to candidate donors, and self-report measures were obtained from 28 women. RESULTS There was a significant discrepancy between psychiatric history of depression and current mood status, as measured by both clinical interview and psychometric self-report data. Nearly one-quarter of candidate donors (22%) reported a history of major depressive disorder; however, all candidate donors denied current mood disturbance on clinical interview, and mean Beck depression inventory and profile of mood states scores were lower than expected compared with psychometric norms (P < 0.0005), epidemiological data and the recurrent nature of depressive disorders. CONCLUSIONS Candidate donors may minimize psychiatric symptoms. Given the potential for ovarian stimulation protocols to induce or exacerbate mood symptoms, and the moderate heritability of mood disorders, careful evaluation of candidate donor affective disorder history is recommended. This evaluation should focus on sensitivity to mood destabilization during times of hormonal change. Measures that examine whether a candidate donor may have a tendency to present herself in an overly favorable manner, and/or a tendency to minimize symptoms, are recommended.

Oocyte cryopreservation as a fertility preservation measure for cancer patients

Advances in cancer treatment have allowed women to live longer, fuller lives. However, gonadotoxic therapies used to effect cancer 'cures' often significantly impair a woman's reproductive potential. Thus, in accordance with improved survival rates,there is an increase in demand for fertility preservation. Initially, fertility preservation was limited to embryo cryopreservation;therefore, the number of patients enrolling was relatively low. Recently, substantial improvements have increased available options, specifically oocyte cryopreservation, thereby expanding and altering the make-up of the patient population under going treatment for fertility preservation. Patient diversity requires the treating physician(s) to be cognizant of issues specific to cancer type and stage. Furthermore, patients often have comorbidities which must be attended to and addressed. Although not all patients will be candidates for, or will elect to pursue, fertility preservation, all should receive counselling regarding their options. This practice will ensure that the reproductive rights of those patients facing impending sterility are maintained. Here, fertility preservation protocols, practices and special considerations, categorized by most frequently encountered cancer types, are reviewed to guide reproductive endocrinologists in the management of fertility preservation in such patients. The formation of a multidisciplinary patient-structured team will ensure a successful, yet safe, fertility-preservation outcome .

Controlled ovarian hyperstimulation and gestational surrogacy in a patient with lung transplant: a case report

BACKGROUND

Cystic fibrosis (CF) is one of the most common genetic disorders that can often lead to chronic pulmonary disease. Patients with respiratory failure due to CF may achieve a good quality of life after lung transplant, and many will desire to have children.

CASE

A 26-year-old, nulliparous female with CF and double lung transplant presented for fertility treatment. She was successfully treated with controlled ovarian hyperstimulation and gestational surrogacy.

CONCLUSION

Controlled ovarian hyperstimulation and gestational surrogacy is a safe option for patients with lung transplant to have a genetic child.

Parthenogenic blastocysts derived from cumulus-free in vitro matured human oocytes

Background

Approximately 20% of oocytes are classified as immature and discarded following intracytoplasmic sperm injection (ICSI) procedures. These oocytes are obtained from gonadotropin-stimulated patients, and are routinely removed from the cumulus cells which normally would mature the oocytes. Given the ready access to these human oocytes, they represent a potential resource for both clinical and basic science application. However culture conditions for the maturation of cumulus-free oocytes have not been optimized. We aimed to improve maturation conditions for cumulus-free oocytes via culture with ovarian paracrine/autocrine factors identified by single cell analysis.

Methodology/Principal Finding

Immature human oocytes were matured in vitro via supplementation with ovarian paracrine/autocrine factors that were selected based on expression of ligands in the cumulus cells and their corresponding receptors in oocytes. Matured oocytes were artificially activated to assess developmental competence. Gene expression profiles of parthenotes were compared to IVF/ICSI embryos at morula and blastocyst stages. Following incubation in medium supplemented with ovarian factors (BDNF, IGF-I, estradiol, GDNF, FGF2 and leptin), a greater percentage of oocytes demonstrated nuclear maturation and subsequently, underwent parthenogenesis relative to control. Similarly, cytoplasmic maturation was also improved as indicated by development to blastocyst stage. Parthenogenic blastocysts exhibited mRNA expression profiles similar to those of blastocysts obtained after IVF/ICSI with the exception for MKLP2 and PEG1.

Conclusions/Significance

Human cumulus-free oocytes from hormone-stimulated cycles are capable of developing to blastocysts when cultured with ovarian factor supplementation. Our improved IVM culture conditions may be used for obtaining mature oocytes for clinical purposes and/or for derivation of embryonic stem cells following parthenogenesis or nuclear transfer.

Poor prognosis with in vitro fertilization in Indian women compared to Caucasian women despite similar embryo quality

BACKGROUND

Disease prevalence and response to medical therapy may differ among patients of diverse ethnicities. Poor outcomes with in vitro fertilization (IVF) treatment have been previously shown in Indian women compared to Caucasian women, and some evidence suggests that poor embryo quality may be a cause for the discrepancy. In our center, only patients with the highest quality cleavage stage embryos are considered eligible for extending embryo culture to the blastocyst stage. We compared live birth rates (LBR) between Indian and Caucasian women after blastocyst transfer to investigate whether differences in IVF outcomes between these ethnicities would persist in patients who transferred similar quality embryos.

METHODOLOGY/PRINCIPAL FINDINGS

In this retrospective cohort analysis, we compared IVF outcome between 145 Caucasians and 80 Indians who had a blastocyst transfer between January 1, 2005 and June 31, 2007 in our university center. Indians were younger than Caucasians by 2.7 years (34.03 vs. 36.71, P = 0.03), were more likely to have an agonist down regulation protocol (68% vs. 43%, P<0.01), and were more likely to have polycystic ovarian syndrome (PCOS), although not significant, (24% vs. 14%, P = 0.06). Sixty eight percent of Indian patients had the highest quality embryos (4AB blastocyst or better) transferred compared to 71% of the Caucasians (P = 0.2). LBR was significantly lower in the Indians compared to the Caucasians (24% vs. 41%, P<0.01) with an odds ratio of 0.63, (95%CI 0.46-0.86). Controlling for age, stimulation protocol and PCOS showed persistently lower LBR with an adjusted odds ratio of 0.56, (95%CI 0.40-0.79) in the multivariate analysis.

CONCLUSIONS/SIGNIFICANCE

Despite younger age and similar embryo quality, Indians had a significantly lower LBR than Caucasians. In this preliminary study, poor prognosis after IVF for Indian ethnicity persisted despite limiting analysis to patients with high quality embryos transferred. Further investigation into explanations for ethnic differences in reproduction is needed.

Normal pregnancy after tetraploid karyotype on trophectoderm biopsy

OBJECTIVE

To report a case of successful pregnancy after trophectoderm biopsy and fluorescence in situ hybridization (FISH) revealed a tetraploid karyotype.

DESIGN

Case report.

SETTING

A university medical center.

PATIENT(S)

An infertility patient desiring trophectoderm biopsy on frozen blastocysts to facilitate preimplantation genetic screening.

INTERVENTION(S)

Frozen blastocysts were thawed on the evening before transfer. Trophectoderm biopsy was performed the following morning. FISH results were available the same day, and two embryos with tetraploid results were transferred.

MAIN OUTCOME MEASURE(S)

Chorionic villus sample (CVS) and newborn exam.

RESULT(S)

Normal diploid CVS result and a healthy male infant.

CONCLUSION(S)

Although multiple cells can be analyzed using trophectoderm biopsy, abnormalities in the trophectoderm may not be present in the inner cell mass.

Embryo quality before and after surgical treatment of endometriosis in infertile patients

PURPOSE

To investigate the hypothesis that surgical treatment of endometriosis in infertile patients may improve pregnancy rates by improving embryo quality.

METHODS

We conducted a retrospective evaluation of 30 infertile patients treated with in vitro fertilization (IVF) before and after surgery for endometriosis. Patients served as their own controls and only cycles with similar stimulation protocols were compared.

RESULTS

Using standard visual evaluation, embryo quality on day 3 was similar before and after surgical treatment of endometriosis. Fifty seven percent of patients had stage I-II endometriosis and 43% had stage III-IV disease. No patients had a live birth after the first IVF cycle and 43% of patients had a live birth with the IVF cycle after surgery.

CONCLUSIONS

Surgical treatment of endometriosis does not alter embryo quality in patients with infertility treated with IVF.

Ovarian stimulation for fertility preservation in patients with cancer

OBJECTIVE

To evaluate controlled ovarian hyperstimulation (COH) in women with cancer compared with healthy women.

DESIGN

A retrospective cohort study.

SETTING

Academic assisted reproductive technology (ART) program.

PATIENT(S)

Fifty women undergoing oocyte retrieval before cancer treatment and 50 age-matched controls.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Number of oocytes and matured oocytes retrieved, number of fertilized oocytes, days of stimulation, dose of gonadotropins.

RESULT(S)

There were no significant differences in the number of oocytes retrieved (13 vs. 11.5), the number of matured oocytes retrieved (9.7 vs. 9.6), and the number of oocytes fertilized (7.4 vs. 6.8). However, the patients with cancer had a longer duration of stimulation (10.5 vs. 9.0 days) and higher total dose of gonadotropins (4,174 IU vs. 3,416 IU).

CONCLUSION(S)

In our study, reasonable ovarian response was achieved by women with cancer with increased doses of gonadotropins and a longer duration of stimulation.

Obstetric outcomes in donor oocyte pregnancies compared with advanced maternal age in in vitro fertilization pregnancies

OBJECTIVE

To evaluate obstetric complications in women who conceived through donated oocytes compared with women who conceived through assisted reproduction using autologous oocytes.

DESIGN

Retrospective cohort analysis.

SETTING

Stanford Hospital and Clinics and Lucille Packard Children's hospital, both tertiary referral centers.

PATIENT(S)

A cohort of 71 oocyte recipients who underwent in vitro fertilization (IVF) were compared to all women over 38 years who conceived through IVF with autologous oocytes (n = 108) between January 1, 2001, and December 31, 2005, at Stanford University and subsequently delivered infants at Lucille Packard Children's Hospital.

INTERVENTION(S)

Assisted reproductive technology with donor oocytes.

MAIN OUTCOME MEASURE(S)

Obstetric charts of the donor-oocyte recipients were compared for all women over 38 years old who had conceived through IVF with autologous oocytes at the same center (n = 108) and delivered at the same hospital during the same time period. Perinatal complications including preeclampsia, diabetes, preterm labor, preterm premature rupture of membranes and placental abnormalities, mode of delivery, presentation, Apgar scores, gestational age at delivery, and weight were compared between the groups.

RESULT(S)

Oocyte recipients and autologous oocyte controls had similar rates of complications of prematurity, hypertensive disorders of pregnancy, gestational diabetes, and placental abnormalities. Infant birth weights and gestational age at time of delivery were similar between the two groups.

CONCLUSION(S)

This study suggests that women undergoing IVF with donor oocytes are not at increased risk for complications during pregnancy or at increased immediate neonatal complications compared with women of advanced maternal age undergoing IVF with autologous oocytes.

Basal follicle-stimulating hormone as a predictor of fetal aneuploidy

OBJECTIVE

To determine whether an elevated basal FSH concentration is an independent predictor of fetal aneuploidy, as measured in spontaneous abortions (SAB).

DESIGN

Retrospective study.

SETTING

Academic reproductive endocrinology and infertility center.

PATIENT(S)

All women with karyotypes of chorionic villi isolated from first trimester spontaneous miscarriages at the time of dilation and curettage from 1999 to 2006. The highest basal serum FSH level in the year preceding dilation and curettage was recorded.

INTERVENTIONS(S)

Monitoring of early pregnancy.

MAIN OUTCOME MEASURE(S)

Fetal karyotype.

RESULTS(S)

A total of 177 spontaneous miscarriages with karyotypes (70 euploid and 107 aneuploid) were identified, of which 53% were conceived by IVF. The aneuploid cohort consisted of trisomic (87%), teraploid (9.3%), and monosomic (3.7%) gestations. Using logistic regression analysis, basal FSH was not found to be independently predictive of an aneuploid gestation in our data set.

CONCLUSION(S)

Our data do not support the hypothesis that an elevated basal FSH concentration is associated with an increase in fetal aneuploidy. Our findings suggest that the association between diminished ovarian reserve and SAB may result from nonkaryotypic factors.

Normal pregnancy resulting from a non-pronuclear oocyte at the time of examination for fertilization

PURPOSE

To report the case of a patient undergoing in vitro fertilization (IVF) in which a non-pronuclear (0PN) oocyte resulted in a normal pregnancy.

METHODS

A 36-year-old woman underwent an IVF-embryo transfer treatment cycle.

RESULTS

Four oocytes were retrieved for insemination by IVF. Examination for fertilization revealed two polypronuclearpolygynic and two non-pronuclear oocytes. The non-pronuclear oocytes were observed further for development. One embryo developed from the non-pronuclear cohort and was transferred at the 8-cell stage on day 3. Subsequently, a pregnancy developed, and resulted in the delivery of a healthy term infant.

CONCLUSIONS

Non-pronuclear oocytes may represent a source of developmentally competent embryos, and further observation of this cohort should be considered, particularly in situations involving a low yield of oocytes at retrieval.

Cytogenetic testing of anembryonic pregnancies compared to embryonic missed abortions

PURPOSE

The objective of this study is to determine the rate of abnormalities detected by cytogenetic testing of first trimester miscarriages, in patients with and without an embryonic pole seen on ultrasound.

MATERIALS AND METHODS

A retrospective study of 272 D&Cs for missed abortions in an academic infertility practice from 1999 to 2006. Karyotype results were compared with transvaginal ultrasound findings. Chi-squared analysis was used with a P < 0.05 for significance.

RESULTS

There was a high rate of abnormal karyotypes in all miscarriages (65%). Rates of abnormal karyotypes were 58% and 68% in cases with anembryonic gestations and those with a fetal pole seen, respectively (P > 0.05).

CONCLUSION

The high rate of abnormalities detected in both groups suggests that useful results can be obtained from chromosomal testing of the POC regardless of ultrasound findings. Further studies on the prognostic value and cost effectiveness of chromosomal testing are needed.

Comparison of obstetric outcomes in recipients of donor oocytes vs. women of advanced maternal age with autologous oocytes

OBJECTIVE

To evaluate obstetric complications in women conceiving with donated oocytes as compared to controls of advanced maternal age.

STUDY DESIGN

We compared the obstetric outcomes of a cohort of 69 women who conceived through oocyte donation to all women over 38 years old (n = 681) who delivered at the same hospital in the same period. We first compared obstetric complications and outcomes in the entire cohort. Additional comparisons were made while controlling for multiple covariates: maternal and fetal complications, mode of delivery, estimated gestational age and infant weight at delivery.

RESULTS

Women who conceived with donor oocytes were older than controls. In the cohort, oocyte recipients were at increased risk for several obstetric complications. However, when controlling for age and multiple gestations, only preterm labor, preeclampsia and protracted labor were increased in oocyte recipients.

CONCLUSION

Women who conceive with donor oocytes might be at increased risk of complications during pregnancy. When age and multiple gestations are accounted for, these patients remain at risk for preterm labor, preeclampsia and protracted labor requiring cesarean delivery.

Elective single blastocyst transfer in women older than 35

A retrospective review of all patients older than 35 who underwent elective single blastocyst transfer was performed. Twenty-three of the 45 patients (51.1%) have an ongoing pregnancy or liveborn delivery, with a mean age of 37.3 years, demonstrating a clear role for elective single transfer in this relatively older IVF population.

Aneuploidy in the miscarriages of infertile women and the potential benefit of preimplanation genetic diagnosis

OBJECTIVE

To evaluate the frequency of specific aneuploidies in miscarriages in an infertility practice and calculate the potential sensitivities of the different aneuploidy screening options for preimplantation genetic diagnosis (PGD) in this setting.

DESIGN

Retrospective analysis.

SETTING

Academic reproductive endocrinology and infertility practice.

PATIENT(S)

Women with miscarriages that had karyotype analysis on products of conception.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Karyotype of spontaneous abortions compared with commercially available PGD options.

RESULT(S)

Of the 273 karyotypes analyzed, 177 (64.8%) were abnormal. The average age of the patients was 37 +/- 4.5 years. Using a limited five-probe panel, 54 of the 177 (31%) abnormal karyotypes would have been detected. In contrast, an extended PGD panel (using 9, 10, or 12 chromosome probes) would have detected 127, 131, and 140 of 177 abnormalities, 72%, 74%, and 79% respectively. The difference between the limited (5-probe) and extended (9-, 10-, and 12-probe) panels was statistically significant. There was not a statistically significant difference among the extended panels.

CONCLUSION(S)

Most of the abnormalities seen in miscarriages are detectable by PGD with extended panels. A significantly higher percentage of these abnormalities could be detected by screening for 9, 10, or 12 chromosomes compared with only 5.

Risk of monozygotic twinning with blastocyst transfer decreases over time: an 8-year experience

OBJECTIVE

The purpose of our study is to compare the occurrence of monozygotic twinning (MZT) from blastocyst transfer (BT) in our program between an earlier and more recent time period.

DESIGN

Retrospective.

SETTING

Academic IVF practice.

PATIENT(S)

All pregnancies conceived between March 2002 and December 2005 (N = 932) in our program were compared to pregnancies conceived before March 2002 (N = 554), which were the subject of a previous study.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

The incidence of MZT with day 3 embryo transfer and BT were compared between the study and control groups.

RESULT(S)

During the study period, the rate of MZT was not significantly different for BT at 2.3% (9/385) compared to day 3 embryo transfer at 1.8% (10/547). This rate of 2.3% for BT was significantly lower than the rate of 5.6% (11/197) reported at our institution for BT before March 2002.

CONCLUSION(S)

Our study suggests that the risk of MZT with BT is significantly lower in the more recent time period and is in the range of what is seen with cleavage stage transfer. It is likely that improvements in culture systems as experience is gained with BT played a role.

Von Willebrand disease presenting as recurrent hemorrhage after transvaginal oocyte retrieval

A 34-year-old nulligravid woman experienced hemorrhage after each of 2 oocyte retrievals. Initial coagulopathy screening was negative. Treatments used during in vitro fertilization likely interfered with assay performance. Reevaluation remote from medications confirmed the diagnosis of von Willebrand disease. Treatments used during in vitro fertilization may increase bleeding risk and confound coagulopathy evaluation.

Effect of reduced oxygen concentrations on the outcome of in vitro fertilization

We compared the effects of two standard oxygen concentrations, physiological (5% O(2), 5% CO(2), and 90% N(2)) and atmospheric (5% CO(2) with the balance as air), on fertilization, embryo development, and pregnancy rate in 106 patients undergoing IVF, excluding donor oocyte cycles and preimplantation genetic diagnosis cycles. The differences in oxygen concentration did not significantly affect fertilization rate, blastocyst formation, or pregnancy rate, but there was a significant difference in mean embryo score between physiological and atmospheric groups on day 3.

The dilemma of endometriosis: is consensus possible with an enigma?

Many will agree that the use of laparoscopy to diagnose and potientially treat endometriosis in patients who suffer from infertility has been superseded by IVF and sometimes oocyte donation, especially in older patients. The findings of our study add another dimension to management of endometriosis in the setting of infertility and emphasize the importance of keeping laparoscopy in the infertility management equation.

Comparison of GnRH antagonist cycles with and without oral contraceptive pretreatment in potential poor prognosis patients

PURPOSE

To evaluate the effect of oral contraceptive pill (OCP) pretreatment in patients undergoing IVF cycles with an antagonist.

METHODS

In this retrospective study, 194 cycles of women with diminished ovarian reserve undergoing IVF with a protocol using GnRH antagonists were evaluated. Oral contraceptive pretreatment was used in 146 cycles.

RESULTS

Pregnancy rates were the same in both groups. Patients using OCPs required more gonadotropins (5,890 IU) compared to patients not undergoing OCP pretreatment (4,410 IU).

CONCLUSIONS

Pregnancy outcomes were the same whether or not OCP pretreatment was implemented in poor responders using an antagonist protocol. While OCP pretreatment may help with scheduling flexibility, the higher dose of gonadotropins needed for ovarian stimulation should be considered.
