Example text

It offers the advantage of not requiring the removal of testicular tissue. g. assessment of seminal quality after a single dosage with an anthelmintic). Typical sperm output of economically important species Sperm production varies greatly among individuals both within and among species. Several factors contributing to such variability within species have already been described, including inherent differences in testis size and the influences of variables such as age, season (in some species), environmental factors, drugs, etc.

Thus, the semen that is harvested on any given day represents the culmination of a process that for most species extended over at least the previous 60–70 days. Low semen quality could reflect problems with spermatogenesis or epididymal function arising at any time during that period, from which recovery could require a similar length of time. The relationship between frequency of ejaculation and DSO As cited previously, sperm production is not influenced by frequency of ejaculation. During sexual rest, sperm may be lost in the urine (Holtz and Foote, 1972).
