Background:
The WHO 2010 guidelines recognize at-home semen collection as an acceptable alternative to standard collection at the clinic in "exceptional circumstances." There is lack of sufficient data to determine the need for revisiting these recommendations for treatment purposes.
Objectives:
To determine whether at-home semen collection has any effect on intrauterine insemination (IUI) cycle outcomes.
Materials And Methods:
This is a retrospective cohort study of 729 IUI treatment cycles (382 patients) performed at an academic fertility center from September 19, 2019 to December 31, 2020. Semen collected at the "clinic" was used for 343 cycles before the Coronavirus Disease 2019 (COVID-19) pandemic (September 19, 2019 to March 21, 2020), and "at-home" collected specimens were used for 386 cycles following revised protocols with COVID-19-driven changes (May 30, 2020 to December 31, 2020). Logistic regression models were performed to evaluate the effect of "at-home" semen collection on achieving a positive pregnancy test (PPT) and a clinical pregnancy (CP).
Results:
Male and female partners' age, ovarian reserve biomarkers, and stimulation regimens used were similar in the "clinic" and "at-home" groups. In unadjusted models, "at-home" collection had no significant effect on the odds for a PPT [OR (95%CI): 0.733 (0.503-1.069)] or CP [0.816 (0.543-1.226)]. These results persisted even when adjusting for maternal age and anti-Müllerian hormone: PPT [0.739 (0.505-1.081)] and CP [0.826 (0.547-1.248)]. Of the semen analysis parameters under evaluation, only motility appeared to significantly impact the odds of achieving a PPT [1.014 (1.004-1.025)] and a CP [1.017 (1.006-1.029)]. This effect was slightly attenuated for samples collected "at-home" [1.012 (0.997-1.027) and 1.015 (0.999-1.031), respectively, for PPT and CP].
Discussion:
This study adds important information to the limited literature regarding the effect of at-home semen collection on IUI outcomes. Under adequate protocols, at-home semen collection should be considered a safe alternative. Additional research is needed to optimize such protocols.
Conclusion:
Our data suggest that at-home semen collection does not negatively impact IUI pregnancy outcomes.
