It occurs in the ovaries. The spermatids are transformed into spermatozoa sperm by the process of spermiogenesis. The mitotic division of these produces two types of cells. The mature spermatozoa are released from the protective Sertoli cells into the lumen of the seminiferous tubule in a process called spermiation. Consider the Bulls Draft. Anonymous 13 June at
Gametogenesis occurs in both males and females. Further mating results in the F. The hormone inhibin acts to decrease the levels of FSH. It is often completed in the female reproductive tract or in many animals in water because oocytes are released from the ovaries. Spermatozoa are the mature male gametes in many sexually reproducing organisms. If the egg is fertilised however, the peristaltic movements of the fallopian tube move the egg to the uterus where it can implant into the posterior uterine wall.
The Encyclopaedia of Sports Medicine: Each primary spermatocyte then moves into the adluminal compartment of the seminiferous tubules and duplicates its DNA and subsequently undergoes meiosis I to produce two haploid secondary spermatocyteswhich will later divide once more into haploid spermatids.
Thus, spermatogenesis is the male version of gametogenesisof which the female equivalent is oogenesis. Each gamete contains half the genetic material of the spermatogwnesis organism diploid to haploid. Anonymous 30 December at Anonymous 10 February at Further mating results in the F.

The secondary oocyte will only complete meiosis II on fertilisation, giving off a third polar body once meiosis II is completed and a fertilised egg.
Spermatid DNA also oigenesis packaging, becoming highly condensed.
Gametogenesis is of two types: Spermatozoa are the mature male gametes in many sexually reproducing organisms. Draw a labelled diagram of a mature sperm.
The mature spermatozoa are released from the protective Sertoli cells into the lumen of the seminiferous tubule in a process called spermiation.

FSH stimulates both the production of androgen binding protein ABP by Sertoli cellsand the formation of the blood-testis barrier.
