“…Ejaculatory interval and individual variation in semen analysis parameters both impact quantity and quality of sperm. In the context of ejaculatory abstinence and clinical assisted reproductive interventions, Jurema [30] demonstrated improved insemination cycle pregnancy rates when ejaculatory abstinence was equal to or less than 3 days, and Marshburn [31], stated that despite lower numbers of motile sperm available for insemination, abstinence of 2 days or less was associated with higher pregnancy rates.…”

Purpose The purpose of this study was to quantitate changes in seminal volume, sperm count, motility, qualitative forward progression, and total motile sperm cells per ejaculate, across three consecutive ejaculates collected from individuals within 24 h preceding an IVF cycle. Methods Men presenting with oligoasthenozoospermia or asthenozoospemia attempted three ejaculates within 24 h preceding IVF. Ejaculate 1 was produced the afternoon prior to oocyte retrieval, and ejaculates 2 and 3 were produced the morning of oocyte retrieval with 2-3 h between collections. Ejaculates 1 and 2 were extended 1:1 v/v with room temperature rTYBS. Test tubes were placed into a beaker of room temperature water, then placed at 4°C for gradual cooling. Ejaculate 3 was not extended, but pooled with ejaculates 1 and 2 and processed for intracytoplasmic sperm injection (ICSI). Results Out of 109 oocyte retrievals, 28 men were asked to attempt multiple consecutive ejaculations. Among this population, 25/28 (89.3 %) were successful, and 3/28 men (10.7 %) could only produce two ejaculates. Mean volumes for ejaculates 1, 2, and 3 were significantly different from each other (p<0.01); the volume decreased for each ejaculate. Mean sperm counts, motility, qualitative forward progression, and total motile cells per ejaculate for the ejaculates1, 2, and 3 demonstrated the following: ejaculates 2 and 3 were not significantly different, but counts, motility, and total motile sperm were improved over ejaculate 1 (p<0.01). Conclusions Pooling three consecutive ejaculates within 24 h increased the numbers of available motile sperm in this population by 8-fold compared to the first ejaculate alone, facilitating avoidance of sperm cryopreservation and additional centrifugation steps that could affect sperm viability and/or function.

“…This is a cost-effective, non-invasive test that has been integral in the evaluation of male factor infertility for decades [22]. The efficacy of this test lies in the parameters for which it tests, which include pH, volume, color, total count, motility, concentration, and morphology.…”

“…Pregnancy rates are highest when the donor has fewer than 3 days of abstinence before donation [ 32 ]. In a study of the effect of ejaculatory abstinence on insemination, three clinically signifi cant abstinence groups were identifi ed: up to 3 days (group 1), 4-10 days (group 2), and >10 days (group 3).…”
