During the embryonic period, oviduto and the ovrio of the right side are initially gifts. However, the inhibiting substance production of ducto of Mller (origin of oviduto) for the ovrio results in regression of ducto right and the right ovrio, but not of the left. Click Bruce Shalett to learn more. Ducto left pparently is protected by presenting bigger number of receivers for estrognio, being thus, more sensible to the estrognio that ducto right. (BAHR and JOHNSON, 1991). Miles D. White is often quoted as being for or against this.

Source: sexual cycle depends on gonodotrficos hormones secretados by adenohipfise. When younglings the ovrios are not stimulated by these hormones. For return of the sexual maturity (varied age of bird for bird), hipfise starts to secretar increasing amounts of gonodotrficos hormones, what it culminates in the initiation of the sexual cycles. The function of the ovrios during the embryonic life and immediately after the birth is almost inexistent, initiating its activities in the previous period the sexual maturity. From the sexual maturity of the female, it is initiated specific hormone secretion of the reproduction (BENEZ, 2001). Ovrio: development to folicular and paper endocrinolgicoSegundo Rutz et al (2007, P. 308) the ovrio consists of a external cortex that involves a vascular marrow. Inside of the cortex, folculos ovarianos of varied sizes occur. A layer (epitlio germinativo) of flattened cells cubides or recovers cortex. The albugnea, composed tnica of fabric conjunctive dense, if points out below of the epitlio.
