Semen characteristics of fertile Pakistani men.

Semen characteristics were studied among 200 fertile Pakistani men aged 24 to 48 years. Each subject had fathered at least two children. The mean +/- SD values of volume, sperm density, motility percentage, grade of motility and percentage of oval sperms were 3.11 +/- 1.2 ml, 58.21 +/- 26.41 million/ml, 61.2 +/- 21.3%, 3.01 +/- 0.94 and 70.2 +/- 15.36% respectively. There was no deteriorating effect of age on semen quality except some decrease in semen volume. The comparison has been made with studies from other countries.
