Endoscope image of a human ovary and fallopian tube (bottom). The image was taken after a ripe ovarian follicle had released its ovum (egg) into the fimbriae (the feather-like opening) of the fallopian tube. Primordial ovarian follicles are formed between the 4th & 7th month of fetal development and develop into primary follicles at sexual maturity. In each monthly ovarian cyle up to 20 follicles may become activated; only one normally reaches full maturity to release an ovum at ovulation. Here,the identation in the surface of the ovary (top) marks the point at which the ovum was released | |
