Abstract

Sixty-four normozoospermic and 19 oligozoospermic males underwent sperm analyses of two successive specimens obtained at 1-, 2-, and 3-day intervals. The first specimen was produced after 3 days of abstinence. Sperm volume of normozoospermic males declined from 2.3 +/- 1.0 to 1.6 +/- 1.0 ml, 2.6 +/- 1.0 to 2.0 +/- 0.9 ml, and 2.1 +/- 0.9 to 1.9 +/- 1.0 ml at 1-, 2-, and 3-day intervals, respectively. Similarly, oligozoospermic males showed declines from 2.3 +/- 1.2 to 1.7 +/- 1.5 and 2.3 +/- 1.1 to 1.8 +/- 1.2 and an increase from 1.2 +/- 1.2 to 1.5 +/- 0.7 ml, respectively. Sperm counts of normozoospermic males declined from 65 +/- 54 to 55 +/- 34, 83 +/- 57 to 69 +/- 47, and 97 +/- 51 to 81 +/- 46 million spermatozoa/ml at 1-, 2-, and 3-day intervals, respectively. Oligozoospermic males showed declines from 5.1 +/- 5.4 to 3.8 +/- 4.1 and 8.2 +/- 8.6 to 7.2 +/- 5.2 and an increase from 3.8 +/- 0.6 to 5.7 +/- 2.1 million spermatozoal/ml at 1-, 2-, and 3-day intervals, respectively. Sperm motility of normozoospermic males varied from 41 +/- 20 to 38 +/- 18, 55 +/- 14 to 56 1/3 pm 14, and 52 +/- 15 to 52 +/- 20% at 1-, 2-, and 3-day intervals, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
