Semen quality and sperm functional parameters in fertile Indian men.

The reports of a decline in the reproductive health of men worldwide prompted the present study to be undertaken so that baseline semen parameters could be established in Indian men. Semen profile and sperm function parameters were evaluated in 368 Indian men of proven fertility, settled in Delhi. The results of the study were compared with available published information from Indian men. The mean sperm concentration and semen volumes were 68.22 +/- 15.14 x 10(6) ml(-1) and 3.20 +/- 0.94 ml, respectively. Rapid, linear progressive motility and sluggish linear motility were 40.95 +/- 9.15% and 24.95 +/- 7.01%, respectively. A comparison of the results of the present study with earlier published data did not support the contention of a decrease in the semen quality in Indian men.
