Average volume was 2.9 c.c. (range 2.0 ~ 4.3 c.c.) 3. Disappearance rates of spermatozoa from the ejaculate were 31. 25% at 3 times (3 weeks=21 days), 43.75% at 4 times (4 weeks=28 days), 75% at 5 times (5 weeks=35 days), 87.5% at 6 times (6 weeks=42 days) and 93.75% at 7 times (7 weeks=49 days) ejaculate.
