PURPOSE: We aimed to assess whether home collection and increased time to semen processing are associated with altered sperm parameters, fertilization rates (FR), day 5 usable quality blastocyst development rates (D5-UQBR), or pregnancy rates (PR) in patients undergoing IVF/ICSI. METHODS: This was a retrospective cohort study of patients undergoing IVF/ICSI before the coronavirus disease 2019 (COVID-19) pandemic ("clinic" collection, n = 119) and after COVID-19 ("home" collection, n = 125) at an academic fertility practice. Home collection occurred within 2 h of semen processing. Patient sperm parameters, FR (#2PN/MII), D5-UQBR (# transferable and freezable quality blastocysts/# 2PN), and PR in fresh transfer cycles were compared between clinic and home groups with t-tests. The association between time to processing on outcomes was assessed with regression modeling, controlling for potential confounders. RESULTS: Mean male age was 37.9 years in the clinic group and 37.2 years in the home group (p = 0.380). On average, men were abstinent for 3.0 days (SD 1.7) in the clinic group and 4.1 days (SD 5.4) in the home group (p = 0.028). Mean time to semen processing was 35.7 min (SD 9.4) in the clinic group and 82.6 min (SD 33.8) in the home group (p < 0.001). There was no association between collection location and increased time to processing on sperm motility, total motile count, FR, D5-UQBR, or PR. CONCLUSIONS: Our data suggest that increased time to processing up to 2 h with home semen collection does not negatively impact sperm parameters or early IVF/ICSI outcomes.
