Uterine transposition in a patient with vulvar cancer.

Objective: To report the first uterine transposition for fertility preservation in a patient with vulvar cancer.Case: A 26-year-old nulliparous patient with stage IIIB vulvar cancer, which was resected with adequate margins and bilateral inguinofemoral lymphadenectomy.Laparoscopic transposition of the uterus to the upper abdomen, outside of the scope of radiation was performed to preserve fertility and ovarian function. After the end of radiotherapy, the uterus was repositioned into the pelvis.Main Outcome Measure: Uterine and ovarian function preservation. Result: The patient recovered her menstrual cycles spontaneously 1 month after the reimplantation and exhibited normal variation in ovarian hormones.Twelve months after the surgery, the uterus was normal and there was no sign of recurrent disease. Conclusion: Uterine transposition might represent a valid option for fertility preservation in women who require pelvic radiotherapy. However, studies that assess its viability, effectiveness, and safety are required.

Fertility preservation in male cancer patients. Counseling and reproductive outcomes.

Introduction: Advances in cancer treatments have determined an increase in survival rates. However, these lifesaving therapies may have a negative impact on reproductive health. To diminish the infertility risk; different fertility preservation strategies have been designed. Sperm freezing is the gold standard fertility preservation method in the case of post-pubertal men. The main objective of this study is to evaluate the fertility status of Uruguayan male cancer survivors who have gone through sperm freezing, as well as to assess oncofertility counseling received by these patients. Methods: This is a descriptive, cross-sectional, observational, and transversal study. A survey was conducted on male cancer survivors who cryopreserved sperm between 1985 and 2021 in "Reprovita Lab and Biobank" which is the only sperm bank in this country. Results: One hundred thirty-five participants answered the survey. At the time of diagnosis, the mean age of patients was 28.8 ± 6.4 years old. Testicular was the most frequent type of cancer (64%). Only, 12% (n = 15) already had children at the time of diagnosis. Among the interviewed survivors, 50% (n = 62) attempted to conceive after cancer treatment, and 68% (n = 42) achieved natural pregnancy. Patients who did not achieve spontaneous conception (n = 11), used their cryopreserved samples, and 45.4% achieved pregnancy. About 86% (n = 107) of survivors believed that the timing of oncofertility referrals was appropriate and 97% considered that having the possibility of protecting their fertility was very important. Eighty percent (n = 101), were advised by their attending physicians, 14% (n = 18) sought advice from family members or friends, and 4% (n = 5) from oncofertility specialists. Discussion: To our knowledge, this is the first study evaluating the reproductive outcomes of male cancer survivors in our country and the region. Most of the interviewed survivors considered fertility preservation as a positive initiative, independent of their reproductive outcomes, reflecting the importance of fertility preservation counseling as one of the most important aspects for futurequality of life of young cancer patients.

Body mass index, not race, may be associated with an alteration in early embryo morphokinetics during in vitro fertilization.

OBJECTIVE: To assess the relationship between maternal body mass index (BMI) and embryo morphokinetics on time-lapse microscopy (TLM). DESIGN: Retrospective cohort study. METHODS: All IVF cycles between June 2015 and April 2017 were reviewed. Female BMI prior to egg retrieval was collected through chart review. BMI (kg/m2) classification included underweight (< 18.5), normal weight (18.5-25), overweight (25-30), and obese (≥ 30). Embryos' morphokinetic parameters were assessed with TLM and included time to syngamy, 2-cell, 3-cell, 4-cell, and 8-cell. A generalized linear mixed model was used to control for potential confounders and multiple embryos resulting from a single IVF cycle. RESULTS: A total of 2150 embryos from 589 IVF cycles were reviewed and included in the analysis. Classification based on BMI was as follows: underweight (N = 56), normal weight (N = 1252), overweight (N = 502), and obese (N = 340). After adjusting for race and use of intracytoplasmic sperm injection, the mean time to the 8-cell stage in the underweight group was 4.3 (95% CI: - 8.31, - 0.21) h less than in the normal weight group (P = 0.025) and 4.6 (95% CI: - 8.8, - 0.21) h less than in the obese group (p = 0.022). No significant difference was noted between race and TLM after controlling for possible confounders. CONCLUSIONS: Embryos from underweight women were demonstrated to have a faster time to the 8-cell stage than normal weight or obese women. No significant difference was noted for race. This study demonstrates that weight can be a factor contributing to embryo development as observed with TLM.

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.

Can embryo morphokinetic parameters predict euploid pregnancy loss?

OBJECTIVE: To use time-lapse imaging to compare embryo morphokinetic parameters between embryos resulting in euploid pregnancy loss and euploid embryos resulting in live birth. DESIGN: Retrospective cohort study. SETTING: Single academic fertility center. PATIENT(S): All euploid single embryo transfers between October 2015 and January 2018. INTERVENTION(S): Collection and analysis of baseline characteristics, cycle parameters, and outcomes. MAIN OUTCOME MEASURE(S): Embryo morphokinetic measurements assessed with time-lapse imaging for time to syngamy (TPNf), time to two cells, time to three cells, time to four cells, time to eight cells, time to morula, and time to blastocyst. RESULT(S): The study included 192 euploid single-embryo transfers. Of these, the pregnancy rate was 78% (150 of 193) and the live-birth rate was 63% (121 of 193). There were 43 transfers that did not result in pregnancy, 15 biochemical pregnancy losses, 13 clinical losses, and 121 live births. There was no statistically significant difference in age, body mass index, or number of oocytes retrieved between the groups. Unadjusted and adjusted models revealed no differences in the morphokinetics of embryos resulting in euploid miscarriage compared with those resulting in live birth. CONCLUSION(S): Embryos that resulted in a euploid miscarriage did not display evidence of abnormal morphokinetics on time-lapse imaging. Euploid pregnancy loss is likely multifactorial, including both embryo and endometrial factors. Further research is needed to identify factors that can predict and prevent euploid loss.

Non-invasive prenatal testing in the context of IVF and PGT-A.

The high incidence of chromosome aneuploidy in human gametes and embryos is a major cause of in vitro fertilization (IVF) failure and miscarriage. In order to improve live birth rates with single embryo transfer, the use of preimplantation genetic testing for aneuploidy (PGT-A) has significantly increased. PGT encompasses methods that allow embryos to be tested for inherited conditions or screened for chromosomal abnormalities. However, PGT-A is a screening method and results can never be used to definitively predict the chromosomal status of the embryo and fetus. The objective of this manuscript is to review prenatal screening and diagnostic methods available in pregnancies conceived by IVF-PGT-A.

Assessing the impact of delayed blastulation using time lapse morphokinetics and preimplantation genetic testing in an IVF patient population.

PURPOSE: There is clinical evidence that early cleavage timing parameters predictive of blastocyst development also correlate with embryo implantation potential. The aim of this study is to determine the developmental competency of embryos with delayed blastulation. METHODS: Retrospective study performed from 2015 to 2016 at the Division of Reproductive Endocrinology and Infertility at Northwestern University. RESULTS: A total of 2,292 embryos from 524 patients were included. Day 6 blastocysts had statistically significant longer times for every time point analyzed than day 5 blastocysts (p < 0.001). We found no statistically significant difference in euploidy rates between day 5 (44%) and day 6 (41%) embryos (p = 0.573). t7 and t8 time points were independent predictors of euploidy after controlling for day of biopsy (p < 0.015 and p < 0.014, respectively). Intrauterine pregnancy (IUP) and live birth (LB) were less likely to occur after transferring day 6 embryos (p = 0.0033 and p = 0.0359) without previous genetic testing. However, in embryos that undergo preimplantation genetic testing for aneuploidy (PGT-A), there were no significant differences in IUP or LB rates. CONCLUSION: Early time-lapse points can be used to predict embryo development. Day of blastulation may be an independent predictor IUP, with day 6 blastocysts having lower pregnancy and live birth rates. Our data suggests that day 5 and day 6 PGT-A tested embryos show similar rates of euploidy, suggesting that differences in PR seen in the non-PGT-A tested group may be caused by factors other than aneuploidy. Genetic testing technologies in combination with time-lapse microscopy may provide further information to improve IVF outcomes.

The use of a virtual journal club to promote cross-cultural learning in the reproductive sciences.

PURPOSE: Scientific literacy and communication are critical skills in the biological sciences. Journal clubs, in which peer-reviewed academic literature is discussed, are traditionally used to teach students to evaluate the literature, review scientific findings, and learn about historical, controversial, or current topics. METHODS: We used a virtual journal club to facilitate the international interaction between two universities with master's degree programs in the reproductive sciences: the University of Murcia (Spain) and Northwestern University (USA). The virtual journal club occurred over a 2-hour period and was held using Blue Jeans Conferencing Service software and involved a total of 29 students. During this event, the students who were separated physically by thousands of miles discussed and exchanged ideas about a high-impact publication in real time. A survey assessment was administered to students at the University of Murcia following the event. RESULTS: Positive perceptions included the establishment of cross-institutional interactions and the ability to practice scientific communication in another language. Areas noted for improvement included preparation time and engagement opportunities. CONCLUSION: Overall, the virtual journal club is an innovative technology that can easily be broadened and has the potential to foster collaboration, ameliorate multilingual communication, improve cultural competencies, and expand professional global networks.

Do patients who achieve pregnancy using IVF-PGS do the recommended genetic diagnostic testing in pregnancy?

PURPOSE: Patients undergoing in-vitro fertilization (IVF) with preimplantation genetic screening (PGS) are counseled about the limitations of this technique. As part of the consent process for PGS, physicians recommend diagnostic genetic testing performed in early pregnancy to definitively rule out chromosomal abnormalities. We have noted anecdotally, however, that few patients undergo the recommended diagnostic testing. In this study, we are examining if women who conceived using IVF-PGS did early pregnancy chromosomal testing, and if they did, what type of testing they had. METHODS: This study was performed from 2015 to 2017 in the Division of Reproductive Endocrinology and Infertility at Northwestern University. We included patients who became pregnant after IVF-PGS who were seen by the Division of Reproductive Genetics and non-PGS control group. RESULTS: Sixty-eight patients were included. A total of 50 patients (73.5%) opted for non-invasive prenatal screening; 5 (7.4%) had invasive testing (4 had chorionic villus sampling and 1 had amniocentesis). A total of 13 patients (19%) declined further genetic testing. When comparing demographic data, the mean age was significantly higher in the group of patients who pursued non-invasive testing than in the group who declined further testing (37.15 vs 34.05 years old, p < 0.05). Control group declined invasive diagnostic testing. CONCLUSIONS: Most patients who conceive using IVF-PGS do not pursue diagnostic prenatal chromosomal testing. Future studies focusing on decision making in this patient group are warranted to further elucidate why a small percentage of patients opt for diagnostic testing, even when adequately counseled about the inherent limitations of PGS.
