Abstaining and sperm count

896
According to the World Health Organization guidelines, ejaculatory abstinence EA of 2—7 days is recommended for semen analysis. This study aimed to determine how seminal quality may be affected by two EA periods from the same man. The semen was qualitatively analyzed by examining oxidative activity intracellular and seminal plasma , sperm function acrosome integrity, mitochondrial activity, and nuclear DNA integrity , and epididymal function. As expected, samples collected after 1 day of EA showed a decrease in volume and sperm total number compared to samples collected after 4 days of EA. The sperm motility of the samples collected after 1 day of EA was better compared to samples collected after 4 days of EA. Oxidative activity measured was lower after 1 day of EA compared with those measured after 4 days of EA.

The aim of this study was to evaluate the influence of different periods of abstinence on conventional semen parameters as well as functional parameters in human semen, including mitochondrial function, chromatin packing and sperm DNA fragmentation. We recruited a cohort of 2, men undergoing infertility investigation. Associations between the sexual abstinence period and sperm parameters were assessed using Spearman correlation. The duration of abstinence had a statistically significant positive influence on sperm concentration and volume, the number of leukocytes and a statistically significant negative influence on sperm motility and vitality.

The short answer: It depends. Frustrating, we know! Women are most likely to get pregnant during their fertile window, the five days leading up to ovulation. Does it help to do it more often? Sex every other day?
