Introduction
Fertilisation is an internal process in mammals, the gamete cells however are not fully mature when they leave the gonad (either testicle or ovary) and so continue a process of maturation right up to actual fertilisation, the ovum matures fully when it undergoes its second meiotic division, the process for sperm is as follows:
[...]
Introduction
Oogenesis is the female version of gametogenesis and is therefore the female equivalent of spermatogenesis. This process follows the immature, primordial ova right through to its maturation as a fertile ovum (egg).
Two processes which are important in cell division and therefore the creation of gametes (gametogenesis) are meiosis and [...]
Introduction
Spermatogenesis is the biological process whereby spermatogonia (the germ cell) develop into spermatozoa (the mature sperm cells). This process takes place in the seminiferous tubules of the testes; this is the starting point for spermatogenesis. Stem cells adjacent to the inner tubule wall divide, beginning at the walls and proceeding into the innermost part, [...]
