- Abstract
Objective: To detect whether intravaginal exposure to prepared seminal plasma led to an absolute increase in live birth rate (LBR) after in vitro fertilization (IVF) by 10% compared with placebo. It has been suggested that intravaginal deposition of seminal plasma after ovum pick-up (OPU) for IVF treatment, increases pregnancy and LBRs., Design: Double-blind, placebo-controlled prospective study. An outcome assessment was made before the type of intervention was unblinded. The outcome data were analyzed according to an intention-to-treat protocol., Setting: University Hospital., Patients: Couples scheduled for an IVF treatment cycle: in total, 792 couples (393 in the seminal plasma group and 399 in the control group) were recruited over a 5-year period of inclusion in a single-center setting., Intervention: On the day of OPU, the couples were randomized into groups receiving either vaginal deposition of prepared seminal plasma from the partner or saline. Both participants and the physician were blind to the grouping., Main Outcome Measures: The primary outcome was a live birth (LB). The secondary outcomes were a positive pregnancy test, defined as human chorionic gonadotropin identified in urine 3 weeks after OPU , and clinical pregnancy, defined as an intrauterine viable pregnancy assessed using transvaginal sonography after 5-7 weeks., Results: In the index group, 35.4% had a positive pregnancy test (relative risk [RR],0.93; 95% confidence interval {CI} 0.78-1.10), 28.8% had a clinical pregnancy (RR 1.00, 95% CI 0.97-1.03), and 26.5% had a LB (RR 0.86; 95% CI 0.70-1.07), adjusted for day of transfer, female age, and number of fertilized oocytes. Corresponding rates in the control group were 37.3%, 33.6%, and 29.8%. No statistically significant differences regarding outcomes between the two intervention groups were found., Conclusion: Prepared seminal plasma applied in the vagina directly after OPU did not increase the rates of LB or clinical pregnancies. The importance of immunological factors to allow the implantation of an embryo is not questioned, but no improvement in the LBRs in IVF treatment by introducing the male partner's prepared seminal plasma after OPU could be found., Clinical Trial Registration Number: Clinicaltrials.gov, ID NCT02716753.

- Abstract
Research Question: How is the mental health of open-identity gamete donors and their satisfaction with their contributions 14-17 years after acceptance as a donor?, Design: The Swedish Study on Gamete Donation is a longitudinal study comprising women and men who were accepted as donors at seven Swedish university clinics between 2005 and 2008. The latest (fifth) follow-up included 215 open-identity donors (response rate 87%): 123 oocyte donors and 92 sperm donors. The donors answered a questionnaire regarding their perceptions, experiences and expectations after gamete donation 14-17 years previously., Results: The donors were satisfied with the experience of donating, and no differences were detected between sperm and oocyte donors. Oocyte donors were more than twice as likely to feel that family and friends were proud of their donation compared with sperm donors (51% versus 23%, P < 0.001). In total, six donors regretted their donation: four oocyte donors and two sperm donors. Sperm donors were more frequently satisfied with the financial compensation compared with oocyte donors (P = 0.005). No difference in the development of symptoms of anxiety or depression was detected 14-17 years post-donation., Conclusion: Long-term follow-up studies on donors are important for recruiting donors, and for recipients and the children who will be conceived with donated gametes. The results from the current study indicate that donors, generally, have good mental health and do not regret their decision to donate gametes. These findings are reassuring for all parties involved., (Copyright © 2023 The Authors. Published by Elsevier Ltd.. All rights reserved.)

- Abstract
Background: Advanced maternal age, single status and use of assisted reproductive technology (ART) are increasing in mothers in high-income countries, and all are known risk factors for negative obstetric outcomes. Less is known about their long-term consequences for childhood morbidity. Thus, the aim of this study was to investigate morbidity up to five years of age, in the children of older, single, and/or ART-treated mothers., Methods: A cross-sectional using Swedish registers was performed comprising 23 772 children. The prevalence of diagnosis and the number of hospital visits for specialist care, were compared and analyzed in relation to maternal age at childbirth, maternal civil status, and mode of conception. The odds ratio for specialized care within each ICD-chapter were estimated using single and multiple logistic regression., Results: Children born to single mothers and children conceived using ART had significantly more outpatient visits for specialist care and significantly more diagnoses compared to children with married/cohabiting mothers, and spontaneously conceived children. Children born to mothers of advanced maternal age (≥40) had fewer in- and outpatient visits. However, they were significantly more often diagnosed within ICD-chapters XVI, XVII i.e., they experienced more morbidity in the neonatal period., Conclusion: The results indicate that children born to single mothers and children of ART-treated mothers have a higher morbidity and consume more specialist care than children of married/cohabiting and spontaneously pregnant mothers. We conclude that the use of ART, maternal single status and advanced maternal age are risk factors of importance to consider in pediatric care and when counseling women who are considering ART treatment., (© 2022.
