for the present study, and follow-up of histochemical changes in estradiol valerate-induced polycysticovary syndrome (pcos), 48 virgin 90-day-old female rats were used. the rats were divided into thetreatment and control groups. for each rat of the treatment group, 4 mg estradiol valerate was injectedthrough intramuscular route for the induction of pcos. the control group was taken the same amo...

An attempt was made to describe the updated information about the factors to be concerned before using of buffalo follicular fluid for supplementation in vitro of buffalo oocyte. There are not only diameter of the follicle, the present of corpus luteum (CL), growth of follicles, stage of estrus cycle, healthy and atretic state of the ovarian follicles. The progesterone and estradiol-17B concent...

This research was conducted to study the follicular dynamics, hormonal, biochemical profile and fertility response in acyclic and norgestomet+PMSG treated acyclic buffaloes in summer. The study animals were divided into two groups: group I [control (n=8): no treatment] and II [treatment group (n=15)]. In group II, seven animals were used for follicular biochemical and hormonal profile and eight...

BACKGROUND Stress has been proved to impair the porcine reproduction soundly. Endocrine disruption, which is closely related to the persistent follicles, is possibly one of the results of stress, although the mechanism is unclear. Since the expression of luteinizing hormone receptor (LHR) in ovarian follicular wall and concentrations of steroid hormone in follicular fluid are related to the dev...

The concentrations of various components of follicular fluid were compared among three groups of follicles (small, <5 mm; medium: 5-10 mm; large, >10 mm) with a control that consisted of the components of umbilical serum using seven pregnant Antarctic minke whales. Follicular oocytes recovered from the follicles were also used for measurement of oocyte diameter after removing the cumulus cells....

Anti-Müllerian hormone (AMH) is exclusively produced by granulosa cells (GC) of the developing pre-antral and antral follicles, and AMH is increasingly used to assess ovarian function. It is unclear which size follicles make the most AMH (total content) and are the main contributors to circulating AMH concentrations. To determine AMH gene expression in GC (q-RT-PCR) and follicular AMH productio...

Endothelin-like immunoreactivity specific for endothelin-1 (ET-1), endothelin-2 (ET-2) or big endothelin-1 (big ET-1) was measured, using commercially available radioimmunoassay kits, in follicular fluid collected at the time of oocyte aspiration from 36 women undergoing ovulation induction by human menopausal gonadotrophin (HMG). The relationship of ET concentrations to HMG dose, peak serum oe...

OBJECTIVE Aims of this study were 1) to assess sexual function and endocrine profile among fertile type 1 diabetic women during the follicular and luteal phases of the menstrual cycle, 2) to compare these results with those obtained among healthy fertile women who served as control subjects, and 3) to explore the correlations between sexual function and endocrine milieu among patients and contr...

the study was undertaken to elucidatethe beneficial effects of goat follicular fluid (gff) added to maturation and culture media on in vitro maturation, fertilization and post-fertilization development of oocytes in black bengal goats. follicular fluid and oocytes were collected from slaughter house goat’s ovaries using the aspiration technique. media were prepared using tcm-199 supplemented wi...

The objective was to characterise the hormonal composition of follicular fluid from mares with distinct anovulatory-cystic follicles. Follicular fluid was aspirated from six mares that presented with cystic follicles and from pre-ovulatory follicles of five normal mares (controls). Differences in progesterone, oestradiol, testosterone, IGF-I and IGF binding were analysed using Fisher's exact te...
