Both the sperm and ova originate from the germinal epithelial cells. Both the process are controlled by anterior pituitary gland hormones.

ə ˈ dʒ ɛ n ɪ s ɪ s / is the differentiation of the ovum (egg cell) into a cell competent to further develop when fertilized. Production of sperm is called spermatogenesis. It takes place in the gonads of the male - the testes. Over 100 million can be made in one day! Each testis is composed of numerous tiny tubes called seminiferous tubules. It is in the walls of these tubules that sperm production actually takes place.

Short notes on the process of spermatogenesis.

Learn more. Male gametogenesis, also called spermatogenesis, takes place in Sperm development (spermatogenesis) takes place in the ducts (seminiferous tubules) of the testes. Cell division produces mature sperm cells (spermatozoa) All pre-meiotic cells are called spermatogonia; these include regenerating stem cells as well as those that have taken the path to terminal differentiation. With the commencement of meiosis, germ cells are called spermatocytes, and . Oct 19, 2007 The products of the second meiotic division are called spermatids. They are spherical cells with interphase nuclei, positioned high in the The meiotic division in spermatogenesis takes approximately ___ weeks Sperm maturation takes place in the epididymis for about __ weeks.
