Abstract
Purpose: Changing sperm donors after unsuccessful intrauterine insemination (IUI) cycles is a common yet understudied practice. This study evaluates whether switching sperm donors impacts the number of IUI cycles required to achieve pregnancy.
Methods: This retrospective cohort study analyzed 312 women undergoing donor sperm IUI at Lis Maternity Hospital, Tel Aviv Sourasky Medical Center, from 1992 to 2020. Participants were divided into two groups: Group A (conceived using only one donor) and Group B (switched donors after initial unsuccessful attempts). The primary outcome was the number of IUI cycles until pregnancy. Statistical analyses included t-tests, ANOVA, and multivariate analysis of covariance (MANCOVA).
Results: Women in Group A required fewer cycles (mean 3.78 ± 1.90) to achieve pregnancy compared to Group B (mean 6.07 ± 2.95, P < .001). However, after switching donors, the mean number of cycles needed in Group B (2.23 ± 1.61) was significantly lower than the total cycles required by Group A (P < .001). Cumulative live birth rates were higher in Group A (50.5% after three cycles; 81.5% after six cycles) compared to Group B (26.0% after three cycles; 61.9% after six cycles).
Conclusion: Switching sperm donors after repeated unsuccessful IUI attempts significantly reduces the additional number of cycles needed to achieve pregnancy. These findings suggest that sperm-oocyte compatibility may influence IUI success. Clinicians should consider donor replacement after multiple failures. Prospective studies are required to confirm these results and investigate underlying biological mechanisms.
期刊介绍：
The Journal of Assisted Reproduction and Genetics publishes cellular, molecular, genetic, and epigenetic discoveries advancing our understanding of the biology and underlying mechanisms from gametogenesis to offspring health. Special emphasis is placed on the practice and evolution of assisted reproduction technologies (ARTs) with reference to the diagnosis and management of diseases affecting fertility. Our goal is to educate our readership in the translation of basic and clinical discoveries made from human or relevant animal models to the safe and efficacious practice of human ARTs. The scientific rigor and ethical standards embraced by the JARG editorial team ensures a broad international base of expertise guiding the marriage of contemporary clinical research paradigms with basic science discovery. JARG publishes original papers, minireviews, case reports, and opinion pieces often combined into special topic issues that will educate clinicians and scientists with interests in the mechanisms of human development that bear on the treatment of infertility and emerging innovations in human ARTs. The guiding principles of male and female reproductive health impacting pre- and post-conceptional viability and developmental potential are emphasized within the purview of human reproductive health in current and future generations of our species.
The journal is published in cooperation with the American Society for Reproductive Medicine, an organization of more than 8,000 physicians, researchers, nurses, technicians and other professionals dedicated to advancing knowledge and expertise in reproductive biology.
