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.
During this phase, the following events occur: 1  The rise in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone that is produced by the brain. 2  This causes the dominant follicle to release its egg from the ovary.
