Evaluation of Pregnancy Rate in IUI Cycles of Unexplained Infertile Patients for whom hCG Day Coitus is Recommended

Objective: Aim of this study is to investigate whether the recommended coitus on the day of hCG affects pregnancy and live birth rates by increasing intrauterine sperm count in IUI cycles of unexplained infertile patients with male subfertility.Material and Methods: 300 patients data is collected retrospectively from the files of the Ali Kemal Belviranlı Maternity and Children's Hospital İnfertility Clinic between 2018 and 2020.Patients with unexplained infertility in the 18-35 age group whose antral follicle count were within normal limits, FSH value <10 U/L and proven tubal patency by HSG were included in the study.In male partners, total motile sperm count (TMS) between 5X106 and 15X106 were considered as male subfertility.All patients were induced with gonadotropins before IUI.Chi-square test of independence were conducted to determine the relationship between the coitus status of the participants and pregnancy outcomes.Results: We have seen from the retrospectively reviewed patient files that while 152 of 297 patients were recommended only IUI, 145 of them were offered coitus on the day of hCG.8 patients with 29 pregnancies that resulted in delivery applied coit on the day of hCG together with IUI and 21 patients did not apply coitus on hCG day.It was determined that recommended coitus on hCG trigger day in adition to IUI does not improve live birth rates (p>0,05) with male subfertility patients.Conclusion: Although it is a conventional recommendation to suggest coitus with insemination, we concluded that coitus does not improve pregnancy outcomes with male subfertility.
