BACKGROUND Letrozole is the third-generation aromatase inhibitor (AI) most widely used in assisted reproduction. AIs induce ovulation by inhibiting estrogen production; the consequent hypoestrogenic state increases GnRH release and pituitary follicle-stimulating hormone (FSH) synthesis. METHODS A systematic search of the literature was performed for both(More)

OBJECTIVE The aim of this study was to assess the factors associated with the effectiveness of treatment with alendronate (ALN) quantified by a reduction in urinary excretion of N-telopeptide (NTx). METHODS The study is an observational, prospective, multicenter trial, with a 6-month follow-up. Postmenopausal osteoporotic women (densitometric criteria),(More)
The vagina, vulva, vestibule, labia majora/minora, and bladder trigone have a high concentration of estrogen receptors; therefore, they are a sensitive biological indicator of serum levels of these hormones in women. The estrogen loss in postmenopausal women produces a dysfunction called genitourinary syndrome of menopause. The principal therapeutic goal in(More)
At present, healthcare for post-menopausal a-symptomatic women offers a great opportunity to identify risk factors (RFs) for prevention of diseases which cause high mortality or disability. It is always necessary to promote a healthy lifestyle and identify RFs in order to stratify people according their risk of suffering cardiovascular disease (CVD), cancer(More)
