Ovarian physiology: follicle development, oocyte and hormone relationships
The ovarian follicle is the fundamental unit of the ovary. It contains the oocyte that may eventually ovulate, undergo fertilization and form an embryo. It also provides the steroid and protein hormones required for maintenance of the ovarian cycle, the secondary sex characteristics and preparation of the uterus for implantation. Follicle formation and folliculogenesis have been well documented...
متن کاملEffects of 5α-Dihydrotestosterone and 17β-Estradiol on the Mouse Ovarian Follicle Development and Oocyte Maturation
We have previously reported that androstenedione induces abnormalities of follicle development and oocyte maturation in the mouse ovary. In granulosa cells of the ovarian follicle, androstenedione is aromatized to 17β-estradiol (E2). To determine whether the androgen or estrogen acts directly on the follicle to induce the above-mentioned abnormalities, we compared the effects of a non-aromatiza...
متن کاملSpontaneous antral follicle formation and metaphase II oocyte from a non-stimulated prepubertal ovarian tissue xenotransplant
BACKGROUND Current strategies in cancer treatment have markedly increased the rates of remission and survival for cancer patients, but are often associated with subsequent sterility. While there are various options available to an adult female depending on the patient's particular situation, the only realistic option for preserving fertility in prepubertal females is to cryopreserve ovarian tis...
متن کاملHormonal dynamics in the preovulatory ovarian follicle and the oocyte in rat during proestrus
We studied functional and morphological luteinization of granulosa cells in intact preovulatory follicles and in cultured granulosa cells collected from the proestrous follicles of the rat. Steroid hormones were measured by radioimmunoassay in follicles dissected from the ovaries every 2 hrs on the day of proestrus beginning at 8 : 00 hrs and terminating at the time of ovulation. Granulosa cell...
متن کاملOocyte maturation, follicle rupture and luteinization in human cryopreserved ovarian tissue following xenografting.
BACKGROUND Previous studies have demonstrated development of antral follicles in cryopreserved human ovarian tissue after autografting and xenografting, thus indicating successful preservation of follicular function. The study aim was to assess whether these follicles could also undergo periovulatory changes in response to hCG. METHODS Ovarian tissue from three patients were dehydrated in pro...
