In contrast, Julio Collazos, ., of Hospital de Galdakao in Vizcaya and colleagues reported in the April 12, 2002 issue of AIDS that in a study of nearly 200 clinically stable HIV-positive men (average CD4 cell count 451 cells/mm 3 ; 64% with undetectable viral load ), most subjects had testosterone levels within the normal range. Men receiving no anti-HIV therapy had the lowest testosterone, while those using a regimen combining three classes of antiretroviral drugs had the highest levels. Among the 15 men who had both pre- and post-treatment testosterone measurements, levels increased after starting HAART. But because testosterone levels normally begin to decline around age 40 (a phenomenon known as "andropause"), the beneficial effects of HAART on hypogonadism may be offset as treatment enables HIV-positive men to live to older ages.
Tetrahydrogestrinone (THG) - Commonly known as The Clear, Tetrahydrogestrinone (THG is a type of steroid that had only been recently placed into scheduling as of 2005 and is noted unapproved by FDA. It basically binds with the androgen receptor instead of estrogen which makes it effective in increasing endurance for athletes. According to history, this was the secret of winning for the gold medalist Marion Jones, a sprinter athlete. However, longer association with this type of steroid can lead to infertility in both male and female. Using the steroids abuse test kit, a person may be held liable for a positive THG steroid test.
