- Objective: To estimate the prevalence of endometrioma and deep infiltrating endometriosis (DIE), assessed by systematic transvaginal ultrasound examination, in women with subfertility accepted for their first assisted reproductive treatment and to describe the prevalence of endometriotic lesions in different anatomical locations of the pelvis. Design: Cross-sectional study. Setting: Reproductive Medicine Center, Department of Obstetrics and Gynecology, University hospital. Patient(s): A total of 1,191 women with subfertility aged 25–39 years accepted for their first assisted reproductive treatment between December 2018 and May 2021. Intervention(s): All women underwent a systematic transvaginal ultrasound examination. The endometriotic lesions visible on ultrasound examination were described according to the International Deep Endometriosis Analysis group consensus opinion for systematic approach to assess endometriotic lesions. Main Outcome Measure(s): Prevalence of endometrioma and DIE in women with subfertility and prevalence of endometriotic lesions in various anatomical locations of the pelvis. Result(s): Endometriosis prevalence was 21.8%, with endometriotic lesions found in 260 of the 1,191 women. Overall, 125 (10.5%) women had endometrioma and 205 (17.2%) women had DIE. Of these 260 women, 197 (75.8% of women with endometriosis) did not have any previous knowledge about having endometriosis. The most common location for endometriotic lesions was the uterosacral ligaments, with lesions found in 151 (12.7%) of all women. The second most common location was the ovaries containing endometrioma, found in 125 (10.5%) women. Most women had 1 (n = 121, 10.2%) or 2 (n = 82, 6.9%) endometriotic lesions. Conclusion(s): The prevalence of endometrioma and DIE in women with subfertility, diagnosed by systematic transvaginal ultrasound examination, was 21.8%. Of these, three-fourth of women had no knowledge about the presence of disease.

- Multiple birth rates after fertility treatment are still high in many countries. Multiple births are associated with increased rates of preterm birth and low birth weight babies, in turn increasing the risk of severe morbidity for the children. The multiple birth rates vary in different countries between 2% and 3% and up to 30% in some settings. Elective single-embryo transfer, particularly in combination with frozen-embryo transfer and milder stimulation in ovulation induction/intrauterine insemination, to avoid multifollicular development is an effective strategy to decrease the multiple birth rates while still achieving acceptable live-birth rates. Although this procedure is used successfully in many countries, it ought to be implemented broadly to improve the health of the children. One at a time should be the normal routine.

- To perform a stepwise development of the surgical method for robotics-assisted laparoscopy in donor hysterectomy for uterus transplantation (UTx), a unique treatment for absolute uterine-factor infertility.Prospective observational study.University hospital.Eight donors, aged 38-62 years, underwent surgery for retrieval of the uterus and vasculature.Robotics-assisted laparoscopy was performed in donors for 6-7 h with video recording. Conversion to laparotomy was performed for last parts of retrieval surgery.Description, evaluation, and timing of 12 specific surgical steps, as well as surgical outcomes and complications.There was a progression during the course of eight surgeries. In the initial two cases, seven and six items were completed with robotics compared with all 12 items in the last three procedures. The passive surgical time decreased from ∼20% in the first four cases to ∼8% in the last three procedures. The estimated median (range) blood loss, total surgical time, and length of hospital stay were, respectively, 125 mL (100-600), 11.25 h (10-13), and 5.5 days (5-6). Two reversible complications occurred: One patient acquired pressure alopecia, and one developed pyelonephritis.The study demonstrates a clear evolution of a strategy toward fully robotic donor surgery in UTx. This is likely to become the main approach in donor surgery of live UTx donors.NCT02987023.

- Objective: To evaluate reproductive, obstetric, and long-term health of the first completed study of uterus transplantation (UTx). Design: Prospective. Setting: University hospital. Patient(s): Nine live donor UTx procedures were conducted and seven were successful. Donors, recipients, and children born were observed. Intervention(s): In vitro fertilization was performed with embryo transfer (ET) of day 2 or day 5 embryos in natural cycles. Pregnancies and growth trajectory of the children born were observed. Health-related quality of life, psychosocial outcome, and medical health of donors and recipients were evaluated by questionnaires. Main Outcome Measure(s): The results of in vitro fertilization, pregnancies, growth of children, and long-term health of patients were reported. Result(s): Six women delivered nine infants, with three women giving birth twice (cumulative birth rates of 86% and 67% in surgically successful and performed transplants, respectively). The overall clinical pregnancy rate (CPR) and live birth rate (LBR) per ET were 32.6% and 19.6%, respectively. For day 2 embryos, the CPR and LBR per ET were 12.5% and 8.6%, respectively. For day 5 embryos, the CPR and LBR per ET were 81.8% and 45.4%, respectively. Fetal growth and blood flow were normal in all pregnancies. Time of delivery (median in full pregnancy weeks + days [ranges]) by cesarean section and weight deviations was 35 + 3 (31 + 6 to 38 + 0) and -1% (-13% to 23%), respectively. Three women developed preeclampsia and four neonates acquired respiratory distress syndrome. All children were healthy and followed a normal growth trajectory. Measures of long-term health in both donors and recipients were noted to be favorable. When UTx resulted in a birth, scores for anxiety, depression, and relationship satisfaction were reassuring for both the donors and recipients. Conclusion(s): The results of this first complete UTx trial show that this is an effective infertility treatment, resulting in births of healthy children and associated with only minor psychological and medical long-term effects for donors and recipients. Clinical Trial Registration Number: NCT02987023.

- Objective: To determine the temporal expression of angiotensin-converting enzyme 2 (ACE2), a receptor for SARS-CoV-2, in dominant follicles throughout the periovulatory period in women and the regulatory mechanisms underlying ACE2 expression in human granulosa/lutein cells (hGLC). Design: Experimental prospective clinical study and laboratory-based investigation. Setting: University Medical Center and private in vitro fertilization center. Patient(s): Thirty premenopausal women undergoing surgery for tubal ligation and 16 premenopausal women undergoing in vitro fertilization. Intervention(s): Administration of human chorionic gonadotropin (hCG) and harvesting of preovulatory/ovulatory follicles by timed laparoscopy, and collection of granulosa/lutein cells and cumulus cells at the time of oocyte retrieval. Main Outcome Measure(s): Expression and localization of ACE2 in granulosa cells and dominant follicles collected throughout the periovulatory period of the menstrual cycle and in hGLC using quantitative polymerase chain reaction, immunoblotting, and immunohistochemistry. Result(s): ACE2 expression (mRNA and protein) is up-regulated in human ovulatory follicles after administration of hCG. ACE2 expression was higher in cumulus cells than in granulosa cells. hCG increased the expression of ACE2 in primary hGLC cultures; the increase was inhibited by RU486 (an antagonist for progesterone receptor and glucocorticoid receptor) and CORT125281 (a selective glucocorticoid receptor antagonist), but not by AG1478 (an EGF receptor tyrosine kinase inhibitor) or by dexamethasone. Conclusion(s): The hormone-regulated expression of ACE2 in granulosa cells suggests a potential role of ACE2 in the ovulatory process. These data also imply the possible impact of COVID-19 on a vital cyclic event of ovarian function and thus on women's overall reproductive health. However, SAR-CoV-2 infection in ovarian cells in vivo or in vitro has yet to be determined. © 2021 American Society for Reproductive Medicine
