72517-6Spermatozoa [#] in Semen --post ejaculateActive

Term Description

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]

Part Description

LP14765-9   Spermatozoa
A spermatozoon or spermatozoan (pl. spermatozoa), from the ancient Greek (seed) and (living being) is the haploid cell that is the male gamete. After a female ovum is fertilized by a sperm cell it becomes a zygote. Sperm cells contribute half of the genetic information to the diploid offspring and the other hallf is contributed by the female ovum. In mammals, the sex of the offspring is determined by the sperm cells: a spermatozoon bearing a Y chromosome will lead to a male (XY) offspring, whereas one bearing an X chromosome will lead to a female (XX) offspring (the ovum always provides an X chromosome). Sperm cells were first observed by a student of Antoni van Leeuwenhoek in 1677. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
