Objective(s): Some studies suggest that chronic low-grade inflammation is involved in insulin resistance in polycystic ovary syndrome (PCOS). This study assessed possible involvement of alteration in expression of two pro-inflammatory factors, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in adipose tissues of PCOS rats in the impairment of insulin actions. Also, effects of resveratr...

Prenatal androgen shapes genital differentiation. In humans, genital anatomy determines sex of rearing and subsequent behavioral development. Rhesus monkey genital anatomy and neuroendocrine function are sexually differentiated, and behavioral development occurs in a complex social environment. We investigated prenatal hormonal influences on sexual differentiation by suppressing or increasing a...

Whether serum testosterone (T) can become an adjunct test able to validate the PSA-weighted risk of prostate cancer (PR.CA) in the "grey" diagnostic area (PSA =3.0 to <10.0 ng/ml) was investigated. Seven hundred and eighteen men participated in a prostate screening program using the cutoff PSA value of > or =3.0 ng/ml. PR.CA was found in 26% (22/85) of men with PSA testing within the "grey" dia...

BACKGROUND Practical hormonal male contraceptive regimens are likely to have delayed onset and offset of reliable contraception dictated by the length of the spermatogenic cycle and clearance rate of pre-formed sperm from the ductular system. While delayed onset of contraceptive efficacy is an accepted feature of vasectomy, reliable time estimates for a hormonal male contraceptive of time to on...

Human aging is characterized by declines in cognition and fine motor function as well as improved emotional regulation. In men, declining levels of testosterone (T) with age have been implicated in the development of these age-related changes. However, studies examining the effects of T replacement on cognition, emotion and fine motor function in older men have not provided consistent results. ...

AIM To determine the effect of two different extracts of red maca in male rats. METHODS Prostatic hyperplasia was induced in male rats with testosterone enanthate (TE). The study comprised six groups: one control group (group 1), one group treated with TE (group 2), two groups treated with TE and aqueous extract of red maca (groups 3 and 4), one group treated with hydroalcoholic extract of re...

INTRODUCTION Andropause and aging are associated with neuroendocrine dysfunctions. Growth hormone and testosterone play a significant role in several processes affecting adaptation and thereby also everyday functioning. The aim of this research project was to evaluate the effects of recombinant human growth hormone and testosterone enanthate injections on body mass and body composition, aerobic...

PURPOSE We performed a randomised controlled study regarding the effects of androgen replacement therapy (ART) on lower urinary tract symptoms (LUTS) in hypogonadal men with benign prostate hypertrophy (BPH). METHODS Fifty-two patients with hypogonadism and BPH were randomly assigned to receive testosterone (ART group) as 250 mg of testosterone enanthate every 4 weeks or to the untreated cont...
