Expert Solution

ANSWER -

GAMETOGENESIS- SPERMATOGENESIS

spermatogenesis begins at puberty.
Spermatogonia present on the inside walls of seminiferous tubules multiply by mitotic division and increase in number.
some spermatogonia called primary spermatocyte periodically undergo meotic division
formation of haploid cells called secondary spermatocytes.
they further undergo second meotic division to produce 4 haploid Spermatids.
Spermatids are transformed into spermatozoa ( sperms) by the process called Spermiogenesis.
after that sperm head becomes embedded in the sertoli cells and are
released from the seminiferous tubules by the process known as spermiation.
sperm released from seminiferous tubules are transported by accessory ducts.
secreations of epididymis, vas deferens, seminal vessicle and prostate.
together comprises Semen
released through Urethral passage.
gonadotropin releasing hormones LH and FSH takes part.androgen synthesis and secreation is done by leydig cells. FSH act as sertoli cells.

Sperm is produced in testis of male gonads.
