Abstract

Objective: Intrauterine insemination (IUI) is the first-line treatment in couples suffering from various causes of subfertility and infertility. Considering the relatively low rate of pregnancy achieved with each cycle in this method, optimizing various steps in the process including the time interval from sperm collection to IUI may result in an increased rate of success. The goal of this study was to assess the impact of time intervals from the end of sperm processing to IUI (SP-IUI) on the pregnancy rate in IUI.

Materials and methods: This single-center prospective cohort study evaluated couples with normal male partner sperm analysis and idiopathic female infertility undergoing IUI from 2018 to 2021. Cycles were stimulated using subcutaneous recombinant FSH and oral Letrozole. Ovulation was triggered using GnRH antagonist when the leading follicle’s size reached greater than 14mm. The participants were placed in one of the three groups based on SP-IUI: group 1 (0–60 min), group II (60–90 min), and Group III: (>90 min).

Results: 269 couples were included in the study. Sperm processing expectedly resulted in an increased concentration of total sperm count and sperm motility (P<0.001). The rate of chemical or clinical pregnancy, abortion, IUFD, multigestation, pregnancy, term birth, and ectopic pregnancy was not significantly different across study groups (P>0.05).

Conclusion: The results of this study suggest that SP-IUI intervals evaluated in this study do not vary in terms of pregnancy rate or adverse pregnancy outcomes in IUI with normal male partner semen analysis. Hence, infertile couples can be flexible in the collection of semen specimens without time and site (at home or hospital) limitations.
