BACKGROUND Polycystic ovary syndrome (PCOS) is one of the most common endocrinological disorders among women of reproductive age and the leading cause of female infertility. This study intends to evaluate the lipid profile, hormonal levels [free T3 (fT3), free T4 (fT4), thyroid stimulating hormone (TSH), insulin, luteinizing hormone (LH), follicle stimulating hormone (FSH), and prolactin] in PC...

BACKGROUND Adding clomiphene citrate (CC) to FSH for controlled ovarian stimulation (COS) decreases FSH dose required for optimum stimulation. However, because of its anti-estrogenic effects, CC may be associated with lower pregnancy rates offsetting the FSH-dose reduction benefit. Previously, we reported the success of aromatase inhibition in inducing ovulation without antiestrogenic effects. ...

BACKGROUND IVF outcomes in Chinese women are inferior to those of Caucasian patients. Reflecting prematurely diminished ovarian function, women with elevated age-specific baseline (b-) FSH levels are designated to suffer from premature ovarian aging (POA). We investigated if the prevalence of POA differs between these two ethnic populations. METHODS We compared patient characteristics and fir...

Follicle-stimulating hormone (FSH) in the organism together with LH is responsible for follicular growth and maturation of eggs. If the ovaries are not working, FSH levels rise. The most common reason for high serum FSH concentration is in a female who is undergoing or has recently undergone menopause. High levels of follicle-stimulating hormone indicate that the normal restricting feedback fro...

OBJECTIVE Deficiency of sex steroids has a negative impact on bone mineral content. In studies conducted on postmenopausal women and animal studies, elevated follicle-stimulating hormone (FSH) levels were found to be correlated with a decrease in bone mineralization and osteoporosis. The aim of the present study was to evaluate bone mineral density (BMD) in adolescent girls with hypogonadotropi...

The aim of this study was to investigate whether administration of exogenous estrogen affects the changes of leptin and GnRH levels in women with normal menstrual cycle. A total of 18 women received a bolus intravenous injection of 20 mg conjugated estrogen (premarin group) at 0800 during the fifth day of menstrual cycle, while another 18 women were administered 20 mL of normal saline as the co...
