The original intention of testosterone were the treatment of males who have too little or no natural endogenous testosterone production with hypogonadism. Appropriate use for this purpose is legitimate hormone replacement therapy which maintains serum testosterone levels in the normal range.
Many other applications of testosterone includes the following:
- Lack of libido
- Erectile dysfunction
- Penile enlargement
- Height growth
- Bone marrow stimulation
- Reversal of anemia
- Appetite stimulation
Testosterone is often used by athletes to improve their performance. In men, however, a slight increase in testosterone levels can have great effects on their physical shape. Anabolic steroids (testosterone is one of them) have been taken to enhance muscle development, strength and endurance. After a series of scandals and publicity in the 1980s such as Ben Jonhson’s improved performance at the 1988 Summer Olympics, anabolic steroids were designated as “controlled substance.” In the former Eastern Germany even women used it so they would have superior physical abilities to their competitors. The noticeable side effects that took an impact on those women are extensive growth of facial hair and outer look that was man-like.
The different pharmaceutical forms of testosterone for human administration are currently available. Among them are:
- Injectable (such as testosterone cypionate/testosterone enanthate in oil),
- Oral Andriol,
- Bucall Striant,
- Transdermal skin patches and transdermal creams,
- Gels Androgel and Testim,
- Roll on and Nasal Sprays.
