Comparative Aspects of Follicular Development, Follicular and Oocyte Maturation and Ovulation in Cattle and Pigs
The paper describes comperatively aspects of oogenesis and folliculogenesis, oocyte and follicular growth in cattle and pigs. Moreover, gonadotropin dependent regulatory processes of the wave like pattern of follicular growth are discussed in both species as well as functional and morphological changes during oocyte maturation. Finally, time dependent processes after oecurrence of spontaneous o...
متن کاملOocyte Maturation and Development
Sexual reproduction is essential for many organisms to propagate themselves. It requires the formation of haploid female and male gametes: oocytes and sperms. These specialized cells are generated through meiosis, a particular type of cell division that produces cells with recombined genomes that differ from their parental origin. In this review, we highlight the end process of female meiosis, ...
متن کاملFollicular Development and Oocyte Growth
Follicular development begins as early as the fourth month of fetal life [1]. At that time, the primordial germ cells (PGCs) have migrated from the yolk sac endoderm to the gonadal ridge, undergoing mitotic divisions. PGCs are called oogonia once they reach the gonads, then the oogonia enter the first meiotic division and become primary oocytes. Somatic cells originating from the primitive gona...
متن کاملThe Effects of Progesterone on Oocyte Maturation and Embryo Development
Oocyte maturation and embryo development are controlled by intra-ovarian factors such as steroid hormones. Progesterone (P4) exists in the follicular fluid that contributes to normal mammalian ovarian function and has several critical functions during embryo development and implantation, including endometrial receptivity, embryonic survival during gestation and transformation of the endometrial...
متن کاملDynamics of human follicular growth and in-vitro oocyte maturation.
The physiological trigger for meiotic resumption in the human oocyte is the surge of luteinizing hormone, but it can also occur spontaneously if oocytes are released from antral follicles and cultured in vitro. The development of novel techniques for the culture of murine oocytes has raised the possibility of growing human oocytes to maturity in vitro. Such a system could open the door to a num...
