what is spermatogenesis explain the process of spermatogenesis
Answers
The process of formation of spems or spermatozoa (haploid) from spermatogonium (diploid) by meiosis is called spermatogenesis
.. LH and FSH harmones helps in this process.
In testis, the germ cells begin to divide at puberty due to increase in the release of Gonadotropin Releasing Hormone (GnRH) and form sperms. This process is also called Spermatogenesis.
In the inside wall of seminiferous tubules the diploid spermatogonia or primary spermatocytes multiply and increase in number by mitotic division.
Spermatogenesis starts at puberty.
Sperms are produced in testis by immature germ cells known as Spermatogonia.
The spermatogonia are present on the inside wall of seminiferous tubules.
Spermatogonia multiply by mitotic division.
Each spermatogonium is diploid and contains 46 Chromosomes.
Some of the spermatogonia undergo meiosis periodically and are called Primary Spermatocytes.
Primary spermatocytes undergo meiotic division to form two equal, Haploid Secondary Spermatocytes.
Secondary spermatocytes have only 23 Chromosomes.
The secondary spermatocytes undergo 2nd Meiotic division and form four equal, haploid cells known as Spermatids.
Spermatids are converted to spermatozoa which are also called sperms
