OBJECTIVE To evaluate, retrospectively, the roles of endogenous and exogenous luteinising hormone (LH) activity on live birth rate in ovulation induction cycles. METHODS Associations between LH activity at baseline, end of stimulation and live birth rate were analysed in relation to patient characteristics, baseline and end of stimulation variables in WHO group II anovulatory women (n = 155) ...

One hundred and .tWO puberal gilts from nine genetic groups were used to determine the association of two morphological types of Ovarian follicular loss (hemorrhagic and milky) with genetic background of ~gilts, level of feed intake and stage of estrous cycle. At estrus (day 0 of estrous cycle) a lesser prqportion of gilts (P<.05) had hemorrhagic foiiicles than gilts at day-15. While the total ...

Ovulation induction is the method for treating anovulatory infertility. For patients with hypogonadotrophic hypogonadism, the treatment involves administration of both FSH and LH, while HCG is injected for follicle rupture. Pulsatile GnRH has the same effectiveness as gonadotrophins and the advantage of the low multiple pregnancy rate. In polycystic ovary syndrome (PCOS), the first treatment ch...

Eight weeks treatment with Unkei-to induced a significant increase in plasma follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol levels in hyper- (robust) and hypo- (asthenia) functioning patients with first- and second-grade amenorrhea. We observed no significant differences in the rate of change of these hormones between hyper- and hypo-functioning patients. Ovulation o...

Anovulatory subfertility is a heterogeneous condition with various underlying causes, which should be identified with appropriate history taking, physical examination and relevant investigations. Optimisation of body weight is essential in either underweight, overweight or obese individuals. Women with hypogonadotrophic anovulation can be treated with pulsatile gonadotrophin-releasing hormone t...

Ovarian follicular cysts are anovulatory follicular structures that lead to infertility. Hormones play key roles in the formation and persistence of cysts. Inhibins are heterodimeric gonadal glycoprotein hormones that belong to the transforming growth factor-β superfamily. These hormones suppress the secretion of follicle-stimulating hormone. In this report, partial fragment of inhibin-α (INHA)...

PURPOSE To determine if seizure frequency differs between anovulatory and ovulatory cycles. METHODS The data came from the 3-month baseline phase of an investigation of progesterone therapy for intractable focal onset seizures. Of 462 women who enrolled, 281 completed the 3-month baseline phase and 92 had both anovulatory and ovulatory cycles during the baseline phase. Midluteal progesterone ...

Genistein is a soy phytoestrogen that mediates its functions by interacting with the endogenous estrogen receptor β. To investigate the effect of 10mg/kg body weight/ day genistein administration up to 90 days on the ovarian folliculogenesis and its correlation with serum gonadotropins and estrogen, adult Mus musculus were either administered with 1:4 DMSO : PBS (vehicle) or with 10mg genistein...

Background: Ultrasound Doppler is a new technology that has recently been used in large animal reproduction. As the conventional ultrasound (B-mode) it is a noninvasive technique, but with the advantage of allows the assessment of the hemodynamic of reproductive tract in real time. The observation of important features of the vascularization and changes that occur during physiological processes...

BACKGROUND Dominant follicle selection is disturbed in normogonadotrophic anovulatory infertility [World Health Organization (WHO) 2] and remaining early antral follicles are either healthy or atretic. This study was conducted to investigate whether inhibin B serum concentrations (produced by healthy small antral follicles) represent the extent of ovarian abnormalities in WHO 2 women and patien...
