The key to masculinity and vitality is the human growth hormone that separates the boys from the men. It plays a vital role in the creation of muscle mass and strong bones. It contributes to deep voice and even sex drive. Low testosterone in men is known as hypogonadism. As a product of a modern world made for convenience the male body does not go through nearly as much rigorous activity. The lack of daily exercise contributes to the decrease in male testosterone. It can hit as early as the mid 20s and steadily decrease each subsequent year.
Researchers from Monash University in Melbourne and the University of South Australia in Adelaide tested two different doses of the testosterone cream product known as AndroFeme (5 mg and 10 mg doses). After 21 days of daily administration, the 5-mg dose brought postmenopausal women's peak blood levels of total testosterone right into the normal premenopausal range -- with a peak slightly above the upper limit of the premenopause normal and 24-hour average to slightly below the limit. The 10-mg dose raised testosterone levels to a higher peak but only somewhat higher than the norm (50%) over 24 hours.
