Abstract
Purpose: This study aims to evaluate whether using a combined oral contraceptive pill (COCP) pre-treatment before controlled ovarian hyperstimulation (COH) may negatively influence ovarian response in donors and treatments outcomes in recipients when a progestin-primed ovarian stimulation (PPOS) protocol is used in oocyte donation treatments.
Methods: Multicenter retrospective cohort study evaluating outcomes of 397 COH cycles in oocyte donors, with and without COCP pre-treatment. The retrieved oocytes were used for 216 oocyte donation cycles in recipients.
Results: In donors, the No-COCP group obtained a higher number of total, MII, and useful oocytes, similar stimulation days, total FSH dose used, and cancellation rate due to low response, while the COCP group showed significantly higher cancellations for low LH levels, indicative of long-lasting pituitary suppression COCP related. In recipients, both groups showed similar fertilization rate and blastocyst formation rate. Miscarriage rate (MR) was significantly higher in the COCP group, while higher implantation rate, ongoing pregnancy rate (OPR), and live birth rate (LBR) were obtained in the No-COCP group.
Conclusions: Donor response to COH with PPOS protocol appears to be negatively influenced by COCP pre-treatment, with implications for oocyte donation treatment outcomes in recipients, including higher MR and lower OPR/LBR. Further studies are needed to confirm these findings.
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.
