LaboratorySpermatozoa [#] in Semen --post ejaculate
Definition
Total sperm count is obtained by multiplying the sperm concentration by the volume of the whole ejaculate. According to WHO (Cooper et al, 2010), it is recommended to calculate and report the total number of spermatozoa per ejaculate. This parameter provides a measure of the capability of the testes to produce spermatozoa and the patency of the male tract. In a healthy man, the total number of spermatozoa emitted in an ejaculate will depend on the time of abstinence, volume of his testes, size of his epididymal sperm reserve and extent of ductal potency. According to WHO, the lower reference limit (2.5th percentile) is 39 million per ejaculate. [PMID:19934213]
