Objective This retrospective study compared the effect of the luteal phase ovarian stimulation protocol (LP group) with the gonadotrophin-releasing hormone (GnRH) antagonist protocol (AN group) in women with poor ovarian responses. Methods Ovarian stimulation was initiated with 225 IU of human gonadotrophin (hMG) daily. When the dominant follicle diameter exceeded 13 mm, 0.25 mg of a GnRH antag...

BACKGROUND This research investigated the response of vascular active factors, vascular endothelial growth factor (VEGF) and angiotensin-II (AT-II) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS In this clinical trial study, 52 patients with PCOS and 8 control cases were stimulated with human chorionic gonadotropin (HCG) on the ...

BACKGROUND Serum androgen levels correlate with ovarian sensitivity to follicle-stimulating hormone (FSH) but in practice, standard baseline serum testosterone (T) levels prior to in-vitro fertilization (IVF) may not be the most appropriate marker for determination. METHODS Infertile women enrolled in an IVF programme were included in this study. Serum T and Delta4-androstenedione (A), and th...

background and aim: the normal response of h-reflex depression (hd) was reduced in chronic spinal cord injury (sci) patients. the reduction of this normal response can lead to increase the muscle tone and spasticity. the purpose of this study is to investigate the effect of tripolar cathodal stimulation on hd in sci patients.   materials and methods: this study was conducted in 10 volunteered s...

Age related fertility decline varies considerably among women. Therefore, chronological female age, though informative on pregnancy prospects in assisted reproduction, will often not correctly express a woman's reproductive potential. The value of quantitative ovarian reserve tests prior to IVF/ICSI treatment is still subject of debate. From a series of systematic reviews it has become clear th...

BACKGROUND Despite extensive progress in IVF techniques, one of the most difficult problems is the variability in the response to controlled ovarian hyperstimulation (COH). Recent studies show the effects of individual genetic variability on COH outcome. OBJECTIVE To evaluate the correlation between LHβ G1502A polymorphisms in exon 3 of the LH gene and ovarian response to COH. MATERIALS AND...

BACKGROUND Anti-Müllerian hormone (AMH) is produced by the granulosa cells of preantral and small antral follicles and its levels can be assessed in serum. Since the number of ovarian follicles declines with increasing age, AMH levels might be used as a marker for ovarian ageing. Therefore, we studied the relationship between AMH levels and ovarian response during ovarian stimulation for IVF. ...
