Oct 9, Sure, if a guy ejaculates before sex, those specific sperm—as long as they're nowhere near a woman's vagina—aren't in the running to get her pregnant.

A second ejaculate within an hour after the first can yield a better sample quality ( volume, count and motility) for assisted reproductive techniques in suspension, containing 2× spermatozoa was incubated with SYBR and PI to final concentrations of 1 μM and 12 μM, respectively prior to flow cytometry analysis.

May 21, We observed that during periods of high ejaculation frequency the sperm concentration initially decrease, but then remained within the same range for the remainder of the DE period, similar results have been previously reported [34].

The initial total sperm count was substantially higher and that can be.

Description:This article has been cited by other articles in PMC. The aim of the study was to assess the effect of four repeated ejaculations on the same day at two-hour intervals on conventional and functional semen parameters. Furthermore, intracellular reactive oxygen ROS production, sperm DNA fragmentation and mitochondrial function were evaluated by flow cytometry. An overall decreasing trend was noted in the conventional semen parameters at second, third and fourth evaluations after two hours of abstinence in comparison to first evaluation after 3—4 days of abstinence. The findings of the present study indicate the potential use of additional semen samples with repeated ejaculations at short abstinence times in assisted reproduction procedures particularly from severe oligospermic men. DNA fragmentation, Repeated ejaculation, ROS, Semen parameters, Sperm quality Introduction Spermatogenesis is influenced by several aspects, those including metabolic, genetic, environmental and physiological factors.
