Role of Testosterone in Humans

Natural testosterone is a steroid hormone, normally produced by the Leydig cells in the testes of humans and animals. Females produce far less testosterone in their ovaries than males do their testicles. The small amount of testosterone present in females does not have a masculinizing effect on them. Testosterone increases libido and affects mood in both sexes.

Testosterone is classified as an androgen (masculinizing substance). Androgens control masculine secondary sex characteristics, like male hair growth patterns (beard, armpits, chest and groin), deep voice, and male fat distribution. Testosterone is crucial for the development and maintenance of the male sex organs (testes and penis).

Testosterone is also an anabolic, meaning it encourages bulky, strong muscle growth.

Testosterone has systemic anabolic effects. It influences fluid balance by making the male retain electrolytes (sodium, potassium, and chloride), water, and nitrogen. Testosterone influences bone growth by encouraging the retention of calcium and phosphate. Testosterone makes the skin more vascular and less fatty.

Riding the Lifecycle
Testosterone production increases when a boy enters puberty. Testosterone production decreases when a man turns 50. A good testosterone target range for an adult Klinefelter man to maintain is 250—1,000 nanograms per deciliter (ng/dl) of blood serum. Rubbing a teaspoon of 5% natural testosterone cream every morning into your arms, shoulders, abdomen, or scrotum can help maintain this target range. Allow the cream to absorb into the skin before dressing. Wash your hands well with soapy water after use. Avoid close physical contact with women and children after application.

There are no reports of acute testosterone overdose in the literature; however, Andromen® Forte 5% Testosterone Cream is too strong for women and children.

Lawley Pharmacy offers a 1% testosterone cream product for use by women.

Before using testosterone, for any reason, it is vital you consult with your doctor.
