Development of Ovary
The ovaries develop from the mesodermal ridges along the posterior abdominal wall in relation to other urinary organs like kidney.
Initially, the gonads appear as a pair of longitudinal ridges located on either side of the midline along the posterior wall of the embryo between the mesonephrus and dorsal mesentry (fig. 6). They are formed by proliferation of the coalomic epithelium and the condensation of the underlying mesenchyme
The primitive germ cells appear at about 3rd week of development which have an inductive influence on further development of the gonads into testis or ovary
The germ cells begin to arrive in the rudimentary gonad. if the developing individual has a normal female sex chromosome make up (XX), then the rudimentary gonads develops into an ovary; the stroma of the organ (gland) provides follicles cells and the germ cells eventually provide eggs
The ovary after been formed in the abdomen, they descend down into the true pelvis carrying along their blood supply. Within the pelvis, the ovaries grow progressively larger and changes shape and position between the birth and puberty. They are lifted out of the true pelvis due to uterine enlargement.
