1) Body Composition
Increased testosterone can have an impact on body composition. Possible benefits include gains in lean muscle mass, reduced body fat and increased bone density. Testosterone inhibits uptake of triglycerides and increases lipid mobilization from adipose tissue, and the increase or decrease of testosterone will usually have an inverse effect on fat stores, with higher testosterone generally causing a decrease in body fat. "The Journal of Clinical Endocrinology and Metabolism" published a study in 2007 that showed decreases in body fat and increases in lean mass in HIV-positive obese men given testosterone therapy. In 1989, a study of the effects of testosterone on muscle mass at the University of Rochester School of Medicine and Dentistry suggests that increasing testosterone increases protein synthesis in muscles. Body composition changes from increased testosterone were also demonstrated in a 1999 study at the School of Exercise Science and Sports Management, Southern Cross University in Australia performed on male weight-training subjects, which showed increases in arm girth and body weight and decreased body fat following a 12-week cycle of testosterone enanthate.
2) Sexual Performance
Testosterone replacement therapy can successfully treat erectile dysfunction and loss of libido in men with low testosterone from either advancing age or hypogonadism. Although the effects of increased testosterone are more dramatic in hypogonadal men there are also benefits to the libido of men with normal gonadal, also called eugonadal, function. In a 2004 study published in the "Journal of Endocrinology and Metabolism," researchers found that increasing peak testosterone levels to between 400 and 500 percent above baseline in subjects resulted in a significant increase in sexual arousability over placebo subjects.
3) Emotional Health
Low testosterone levels have a dramatic effect on emotional state. The American Academy of Family Physicians lists depression, impaired cognition and increased fatigue as symptoms of low testosterone production, or hypogonadism. Testosterone replacement therapy for hypogonadal men has successfully reduced negative moods relating to fatigue and depression while increasing feelings of self-esteem. Increasing testosterone in eugonadal men has also shown positive emotional benefits such as increased feelings of self-esteem and reduction of fatigue. The intensity of these benefits is dependent on dosage; a wide body of literature on testosterone increase has shown that at higher dosage aggression, and aggressive response, can become pronounced.
Subtle Symptoms of Low Testosterone:
The symptoms of low testosterone are sometimes obvious, but they also can be subtle. Testosterone levels decline naturally in men as they age over decades. But certain conditions can also lead to an abnormally low level. Symptoms of low testosterone include:
Low sex drive (libido)
Fatigue and poor energy level
Decreased muscle mass
Body and facial hair loss
Low sense of well-being
Testosterone replacement therapy is available in several forms. All can improve testosterone levels:
Skin patch (transdermal): Androderm is a skin patch worn on the arm or upper body. It's applied once a day.
Gels: AndroGel and Testim come in packets of clear testosterone gel. Testosterone is absorbed directly through the skin when you apply the gel once a day. AndroGel, Axiron, and Fortesta also come in a pump that delivers the amount of testosterone prescribed by your doctor. Natesto is a gel applied inside the nose.
Mouth patch: Striant is a tablet that sticks to the upper gums above the incisor, the tooth just to the right or left of the two front teeth. Applied twice a day, it continuously releases testosterone into the blood through the oral tissues.
Injections and implants: Testosterone can also be injected directly into the muscles, or implanted as pellets in the soft tissues. Your body slowly absorbs the testosterone into the bloodstream.
