Follicle Wall,licular wall of maturing follicles in the ovaries of reptiles and birds have been clearly demonstrated. Little attempt has been made, however, to correlate, the results of various techniques applied to the follicle wall of developing and maturing oocytes in the ovaries of reptiles and birds.

Maturation of Ovum, only when the process of meiosis is strongly coupled with the fusion of sperm and egg. This coupling between the two events exists also in reptiles and birds whose oocytes are arrested at the prophase of the first meiosis (prophase I or diplotene) (Chap. 1 and 2) when synthetic activities of oocyte

Ovulation, vascular apical surface of the follicle (Fig. 7.2) which is also called the macula pellucida. Corresponding to these structural and chemical changes in the follicle wall, changes also occur in the quality and quantity of hormones during the preovulatory and ovulatory periods. Details of all these c

Introduction,odent pests; among reptiles, turtles are receiving special attention with the aim of developing farms for turtle egg and meat production in some parts of the world. With the evolution of the amniotic (cleidoic) egg in reptiles, reproductive patterns became considerably modified in them. Turtles, cro

Germinal Beds, Oogenesis and Folliculogenesis, regard to the presence or absence of germinal beds in the adult ovaries. The germinal bed(s), which constitute the sites for the multiplication of oogonia and formation of primordial oocytes, occur in the ovaries of reptiles. No such structures occur in the adult avian ovary which, however, shows p
