spermatocyte
(noun)
A male gametocyte, from which a spermatozoon develops.
Examples of spermatocyte in the following topics:
-
Spermatogenesis
- Each primary spermatocyte divides into two secondary spermatocytes and each secondary spermatocyte into two spermatids or young spermatozoa.
- Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, which in turn produce four spermatozoa.
- Secondary spermatocytes later divide into haploid spermatids.
- 2) Spermatidogenesis: The creation of spermatids from secondary spermatocytes.
- Diagram of the steps of spermatocytogenesis, including type Ad spermatogonium, type Ap Spermatogonium, type B spermatogonium, primary spermatocyte, and secondary spermatocyte.
-
Gametogenesis (Spermatogenesis and Oogenesis)
- Meiosis begins with a cell called a primary spermatocyte.
- At the end of the first meiotic division, a haploid cell is produced called a secondary spermatocyte.
- Four sperm result from each primary spermatocyte that goes through meiosis.
- During spermatogenesis, four sperm result from each primary spermatocyte, which divides into two haploid secondary spermatocytes; these cells will go through a second meiotic division to produce four spermatids.
-
Hormonal Regulation of the Reproductive System
- In males, FSH stimulates primary spermatocytes to undergo the first division of meiosis, to form secondary spermatocytes, leading to the maturation of sperm cells.
-
Semen
- Sertoli cells, which nurture and support developing spermatocytes, secrete a fluid into seminiferous tubules that helps transport sperm to the genital ducts.
