The duration of spermatogenesis, i.e., the time between spermatogonial divisions and the release of the spermatozoon, is approximately 60 days in most domestic animals. Epididymal transit takes a further 8 to 14 days. Thus the interval between the most sensitive stage of spermatogenesis, meiotic prophase, and ejaculation is approximately 30 days (Amann & Schanbacher 1983). Hence the interval between damage to the testis and the appearance of abnormal spermatozoa in the ejaculate is generally between 30 and 60 days, depending on the site of damage.
