Abstract Objective To elucidate the effect of age and sexual abstinence on semen quality (semen volume, total count, progressive motility, vitality and morphology). Methods A total of 730 semen samples were analyzed. Subjects were grouped according to the age (20-29, 30–34, 35–39 and 40–50) and abstinence (2–3, 4–5 and 6–7). Semen parameters were evaluated following WHO standard criteria. Results Analysis of 730 semen samples showed negative correlation of progressive motility ( r =-0.131, P r =-0.173, P r =-0.324, P H = 20.65, P H = 13.53, P H = 15.33, P U test confirmed the changes in semen volume, total count and vitality in paired grouping from 2–7 days ( P P Conclusions In the present study, age negatively affected progressive motility, vitality and morphology of human sperm. Semen samples showed intra varied results within WHO amended abstinence period.
