GnRH from the hypothalamus stimulates the anterior pituitary to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which act on the ovary to promote folliculogenesis
and the concomitant synthesis of estradiol.
Histological studies of ovaries in the control group showed different types of follicles at all stages of folliculogenesis
(primordial follicles, primary follicles, secondary follicles, mature follicles), and corpus luteum.
9] Natural occurring mutations in sheep such as FecXG, FecXB, FecXI, FecXH, FecXL [12,13,14] lead to infertility in homozygous ewes that due to defects in early folliculogenesis
, whereas heterozygous ewes have increased ovulation rate and litter size.
16) found that anti-ZP Abs were detrimental to normal folliculogenesis
and oocyte development.
The ovary, folliculogenesis
, and oogenesis in teleosts.
, spermatogenesis), the absence of exposure data on short-lived chemicals such as bisphenol A and phthalates (Crain et al.
In the same session the roles of FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone) in the initiation and continuation of folliculogenesis
in the natural menstrual cycle will be defined.
Premature ovarian failure (POF) is a heterogeneous syndrome characterized by lack of folliculogenesis
and ovarian estrogen production, associated with secondary amenorrhea and infertility in women under the age of 40 years.
The inhibitory or stimulatory effect of cumulus cells derived from antral follicles was a stage dependent process during in vitro folliculogenesis
in the porcine.
in the fetus, primordial follicles develop to primary follicles, then secondary, and antral follicles.
Drawn from those presented at a forum held October 2005 in Avallon, France, the 21 papers include such topics as folliculogenesis
in polycystic ovaries, appropriate imagery, polycystic ovaries as distinct from PCOS, genetic analyses, fetal origins of PCOS, pubertal precursors, variations in expression of the PCOS phenotype, acquired PCOS and its possible causes, early recognition and prevention, the role of insulin, obesity in PCOS, therapies for metabolic defects in PCOS, hyperabdrogenism, ovulation induction, pregnancy and the impact of diagnostic criteria.
and ovarian histology of the oviparous gecko, Hemidactylus mabouia (Sauria: Gekkonidae).
