Bioavailable testosterone as a correlate of cognition, psychological status, quality of life, and sexual function in aging males: implications for testosterone replacement therapy.

Andropause is a syndrome described in aging males, is composed of a constellation of physical, sexual, and emotional symptoms, and is thought to be related to declining concentrations of serum testosterone. Numerous studies of testosterone replacement therapy in elderly hypogonadal males have documented the physical benefits of such treatment, but have failed to assess cognition, psychological functioning, and quality of life. Male outpatients greater or equal to 55 years of age completed cognitive, psychological, sexual, and quality of life assessments. A serum sample was provided for bioavailable testosterone assay. The associations between bioavailable testosterone concentrations and neuropsychological testing were assessed using Spearman rank correlation. Overall, bioavailable testosterone was not an important determinant of cognitive, psychological, or sexual functioning or of quality of life. The implications for future studies involving testosterone replacement therapy are discussed.

Psychosexual effects of three doses of testosterone cycling in normal men.

BACKGROUND: Testosterone is receiving increased attention for contraceptive and therapeutic indications. The potential psychosexual side effects of testosterone therapy and withdrawal are unclear. METHODS: Healthy men between the ages of 21 and 40 years were recruited via advertisement for a randomized, controlled, double-blind study of acute and withdrawal effects of three doses of testosterone. Two weeks of placebo injections were followed by one of three randomized weekly doses of testosterone cypionate (100 mg, 250 mg, or 500 mg) for the next 14 weeks. Twelve weeks of placebo injections followed during the withdrawal phase of the study. Psychosexual effects were monitored throughout the study. RESULTS: All doses of testosterone demonstrated only minimal effects on measures of mood and behavior during acute and withdrawal phases for all study completers. There were no effects on psychosexual function. There was no evidence of a dose-dependent effect on any measure. One noncompleter on 500 mg of testosterone developed a brief syndrome with symptoms similar to an agitated and irritable mania. CONCLUSIONS: Doses of testosterone up to five times physiologic replacement dose appear to have minimal risk of adverse psychosexual effects in the majority of normal men; however, beginning at around 500 mg per week of testosterone cypionate, a minority of normal men may experience significant adverse psychological effects. Because illicit anabolic steroid users may use larger doses of multiple drugs under less restrictive conditions, our study may significantly underestimate the psychological effect of steroid use in the community.

Halfway house and family involvement as related to community adjustment for ex-residents of a psychiatric halfway house.

What variables are highly correlated with successful community adjustment? A group of ex-patients who left a halfway house to return to the community were interviewed around their active involvement and perceived support from the staff members of the halfway house, while living on their own or with their families. There was a highly positive relationship between continuing contact with the halfway house and the level of adjustment in the community. The implications for understanding the nature, continuity, and purpose of social supports for this group are discussed.
