spermatogenesis

 [sper″mah-to-jen´ĕ-sis]
the development of mature spermatozoa from spermatogonia; it includes spermatocytogenesis and spermiogenesis.

sper·ma·to·gen·e·sis

(sper'mă-tō-jen'ĕ-sis),
The entire process by which spermatogonial stem cells divide and differentiate into sperms. The process has three phases: spermatocytogenesis, meiosis, and spermiogenesis.
See also: spermiogenesis, meiosis, spermatocytogenesis.

spermatogenesis

/sper·ma·to·gen·e·sis/ (-jen´ĕ-sis) the process of formation of spermatozoa, including both spermatocytogenesis and spermiogenesis.

spermatogenesis

(spər-măt′ə-jĕn′ĭ-sĭs, spûr′mə-tə-)
n.
Formation and development of spermatozoa by meiosis and spermiogenesis.

spermatogenesis

[spərmat′əjen′əsis, spur′-]
Etymology: Gk, sperma + genesis, origin
the process of development of spermatozoa, consisting of two stages. In the first stage, spermatogonia become spermatocytes, which develop into spermatids. In the second stage, called spermiogenesis, the spermatids become spermatozoa. Also called spermatocytogenesis, spermiogenesis. spermatogenic, spermatogenous, adj.

spermatogenesis

Physiology The production of male sex gametes; the maturational changes that transform spermatids into spermatozoa. See Sperm.

SPERMATOGENESIS

spermatogenesis

(sper?mat-o-jen'e-sis) [? + genesis, generation, birth]
The formation of mature functional spermatozoa. In the process, undifferentiated spermatogonia become primary spermatocytes, each of which divides to form two secondary spermatocytes. Each of these divides to form two spermatids, which transform into functional motile spermatozoa. In the process, the chromosome number is reduced from the diploid to the haploid number.

Spermatogenesis

The process by which sperm develop to become mature sperm, capable of fertilizing an ovum.
