Dynamics 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...
متن کاملComparative 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 کاملEffect of Different Charged Groups of Cow Follicular Fluid Proteins on In Vitro Oocyte Maturation
Follicular fluid (FF) provides a very important microenvironment for the development of oocyte maturation, ovulation and fertilization. The objective of this study was to determine the effect of different charged groups of cow follicular fluid proteins on in vitro oocyte maturation (IVM) when added to cultured maturation medium. The follicular fluid were obtained from dominant follicle and prec...
متن کاملAge-related variations in follicular apolipoproteins may influence human oocyte maturation and fertility potential.
OBJECTIVE To investigate involvement of specific apolipoproteins in the process of human oocyte maturation and age-related infertility as molecular constituents of follicular fluid. DESIGN Laboratory-based observational study. SETTING Basic science laboratory at a large academic institution. PATIENT(S) Follicular fluid obtained from healthy women aged 18 to 45 years undergoing in vitro fe...
متن کاملRelationship between growth hormone concentrations in bovine oocytes and follicular fluid and oocyte developmental competence.
In the last few years, several works suggest that Growth Hormone (GH) is involved in follicular development and oocyte maturation. These actions may reflect endocrine roles of pituitary GH and also account for local autocrine or paracrine activities of GH produced in reproductive tissue. This study was aimed to verify whether the developmental competence of bovine female gametes might be relate...
