Granulosa cells are refractory to FSH action in individuals with a low antral follicle count.
The reason ovarian function and fertility are diminished in women with a low antral follicle count (AFC), despite significant numbers of follicles remaining in ovaries, is unknown. The bovine model is unique to address this question because cattle and women with a low AFC exhibit similar phenotypic characteristics including a diminished ovarian reserve, reduced circulating concentrations of ant...
متن کاملLocalization of atrial natriuretic peptide in pig granulosa cells isolated from ovarian follicles of various size.
The aim of the current study was to present the spatial distribution of atrial natriuretic peptide (ANP) in short-term cultures of pig granulosa cells obtained from small, medium, and large ovarian follicles. The specific immunoreactivity was detected by three monoclonal antibodies recognizing different epitopes of the ANP molecule (Mab 6C3, Mab 6F11, Mab5D3). The specific ANP immunoreactivity ...
متن کاملthe influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
Antral follicle count reliably predicts number of morphologically healthy oocytes and follicles in ovaries of young adult cattle.
Methods to predict numbers of healthy oocytes in the ovaries of young adults could have important diagnostic relevance in family planning and animal agriculture. We have observed that peak antral follicle count (AFC) determined by serial ovarian ultrasonography during follicular waves is very highly reproducible within individual young adult cattle, despite 7-fold variation among animals. Herei...
متن کاملP-94: The Effect of Superovulation on Oviduct and Ovary Structure of NMRI Mice
Background: To determine the effect of ovarian stimulation on the height of the epithelial cells of fallopian tubes and development of ovarian follicles and corpus luteum in NMRI mice. Materials and Methods: Forty female NMRI mice of 6 to 8 weeks were selected and divided into 4 groups: control group, 10 mice that were injected with saline. The second group of 10 mice that were injected with 7 ...
