Excessive erythrocytosis (EE) [hemoglobin (Hb) >21g/dl] observed in natives at high altitude (HA) seems to be due to elevated serum testosterone levels compared with men without EE at HA. The aim of the study was to determine ...

It is known that during sex differentiation, fetal androgens are critical determinants of the male phenotype. Although testosterone is necessary for normal development of male sexual behavior, perinatal androgen treatment ...

This study was undertaken to evaluate the effects of a single implant containing nomegestrol acetate (Uniplant) on plasma levels of sex hormone-binding globulin (SHBG), testosterone, free testosterone, androstenedione and ...

The in vitro effect of testosterone on human neutrophil function was investigated. Blood neutrophils from healthy male subjects were isolated and treated with 10 nM, 0.1 and 10 mu M testosterone for 24 h. As compared with ...

Life at high altitudes (>4000m) is associated with higher erythropoiesis. Haemoglobin ≥21gdl-1 is considered as excessive erythrocytosis and is a sign of chronic mountain sickness (CMS). The present study was designed ...

The effect of ethanolic extract of Fagara tessmannii, wide medicinal plants used on reproductive function in South Cameroon, was investigated in male rats. Twenty male sexually experienced rats (four groups) were orally ...

INTRODUCTION: Androgen decline in the aging man has become a topic of increasing clinical relevance worldwide, as the reduction in testosterone levels has been reported to be accompanied by loss of muscle mass, accumulation ...
