An important hormone that is essential for male growth and development of masculine characteristics, testosterone affects male reproductive and sexual functions, hair growth, muscle mass, as well as maintaining red blood cells levels, energy levels, mood, and density of bones. In men, testosterone is produced in the testicles, while in women, this hormone is produced in the ovaries. However, women have a minuscule proportion of testosterone as compared to men.

Levels of testosterone are at the peak during late adolescence and early adulthood for men. After the age of 30, testosterone levels drop by about one percent each year. This is quite a natural phenomenon. However, sometimes testosterone levels decline drastically. The causes for this may include the following:

1. Too much iron in the body, also known as hemochromatosis.
2. Hypothalamus or a dysfunction of the pituitary gland.
3. Diseases caused due to inflammation.
4. Liver cirrhosis.
5. Radiation treatment for any kind of cancer.
6. Loss of testicles due to injury or infection.
7. Lifestyle problems such as alcoholism, stress, obesity, and so on.
