The development of the gonads is part of the prenatal development of the reproductive system and ultimately forms the testes in males and the ovaries in females. The gonads initially develop from the mesothelial layer of the peritoneum. The ovary is differentiated into a central part, the medulla, covered by a surface layer, the germinal epithelium.
In concert with the other pituitary gonadotropin follicle stimulating hormone (FSH) it is necessary for proper reproductive function:   * In the female, an acute rise of LH - the LH surge - triggers ovulation.
