PURPOSE OF REVIEW This review discusses ovarian reserve tests for ovulation induction and their application in determining fertility capacity, and their current applications to assess risk of natural ovarian failure and to estimate ovarian function after cancer treatment. RECENT FINDINGS The current arsenal of ovarian reserve tests comprises hormonal markers [basal follicle stimulating hormon...

Five Murrah buffaloes were studied ultrasonographically to record the biometry of the ovarian structures and superovulatory response during superovulation (SOV) following follicle ablation. Transvaginal ultrasound-guided follicle aspiration / ablation (FA) was done at the middle of the oestrous cycle (day 10) on follicle of over 10 mm diameter, using 5.0 MHz convex-array intravaginal transducer...

Context Neurokinin B (NKB) is obligate for human puberty, but its role in adult female gonadotropin secretion and ovarian follicle growth is unknown. Objective To investigate antagonism of NKB on pulsatile gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) secretion and ovarian follicle development in healthy women. Design Open investigation of the effects of a neurokinin-3 ...

In the growing heifer calve, there is an early post-natal, gonadotrophin driven increase in ovarian antral follicle growth. The endocrine regulation of and reason for this initial stimulation of ovarian follicular development are not fully understood. This initial endocrine activity appears to be later held in check by negative feedback suppression mechanisms until the heifer is of a sufficient...

Effective controlled ovarian stimulation (COS) is crucial for IVF outcome. Ovarian response to follicle-stimulating hormone, however, varies widely among women undergoing ovarian stimulation. Advance identification of patients who will elicit a poor or high response to standard treatment would be of great clinical benefit for such patients. Application of pharmacogenetics to ovarian response ma...

BACKGROUND This secondary analysis aimed to identify predictors of low (<6 oocytes retrieved) and high ovarian response (>18 oocytes retrieved) in IVF patients undergoing controlled ovarian stimulation with corifollitropin alfa in a gonadotropin-releasing hormone (GnRH) antagonist protocol. METHODS Statistical model building for high and low ovarian response was based on the 150 μg corifollit...

Ovarian follicle maturation (OFM), including the resumption of meiosis in oocyte, is under hormonal regulation. Insulin-like growth factors (IGF) have been shown to participate regulation OFM with species-specific actions teleost fishes. In present study, vitro treatment rainbow trout ovarian follicles recombinant human insulin-like factor-1 (rhIGF1) or rhIGF2 did not induce germinal vesicle br...

There are now convincing data showing that cystectomy of the endometrioma is not only no cure of infertility, but may harm follicle reserve. The question arises why is cystectomy for an endometrioma, in contrast with other -benign cysts, a risk for follicle reserve and how can ovarian damage be prevented. Surgical specimens of ovaries with endometrioma in situ show in the majority of cases mani...

Background The aim of this study was to evaluate the efficacy and safety of a recombinant human follicle stimulating hormone (r-FSH) low-dose step-up regimen for controlled ovarian hyperstimulation in patients undergoing ovulation induction (OI) with intrauterine insemination (IUI). MaterialsAndMethods The study was conducted in the Department of Obstetrics and Gynecology, Far Eastern Memorial ...
