Physical gestures are prominent features of many species' multimodal displays, yet how evolution incorporates body and leg movements into animal signaling repertoires is unclear. Androgenic hormones modulate the production of reproductive signals and sexual motor skills in many vertebrates; therefore, one possibility is that selection for physical signals drives the evolution of androgenic sens...

Androgenic alopecia as a physiologic process and benign prostatic hyperplasia (BPH) as a pathologic process in the older population are androgen-dependent processes influenced by 5-alpha reductase enzyme which converts testosterone to dihydrotestosterone. This cross sectional study was done to evaluate the relationship between androgenic alopecia and BPH. 150 men older than 50 years old, who pr...

BACKGROUND Nomegestrol acetate (NOMAC), a synthetic progestogen derived from 19-nor-progesterone, recently completed clinical trials for use with 17beta-estradiol in a new monophasic combined oral contraceptive. In this review, published as well as previously unpublished preclinical studies that detail the effects of NOMAC on estrogenic, progestogenic, and androgenic systems, as well as mineral...

BACKGROUND Use of anabolic androgenic steroids (AAS) has been associated with adverse physical and psychiatric effects and it is known as rising problem among youth people. This study was conducted to evaluate anabolic steroids preventative intervention efficiency among gym users in Iran and theory of planned behaviour was applied as theoretical framework. METHODS Overall, 120 male gym users ...
