Define spermiogenesis and spermiation.
Explanation Spermiogenesis is the process through which the spermatids develop into sperms (spermatozoa). Hormones acting in the spermiogenesis are: The luteinizing hormone (LH) is secreted by the anterior pituitary and acts on the Leydig cells to stimulate the secretion of androgens. Follicle stimulating hormone (FSH) also acts on the Sertoli cells to secrete factors which help in spermiogenesis. The sperm heads get embedded in the Sertoli cells to derive nutrition. Follicle Stimulating Hormone and androgen act on the receptors of Sertoli cells to release the sperms from it. Hence, the release of the sperms from the Sertoli cells into the seminiferous tubules is called spermiation. Final Answer The process in which the spermatids develop into sperms is spermiogenesis. The process in which sperms are released from the sertoli cells into the seminiferous tubules is spermiation.
