WHAT PROVIRON IS USED FOR
Proviron is used to replace testosterone in men with hypogonadism. Male hypogonadism is a condition when the body does not produce enough testosterone.
Testosterone is a natural male hormone, known as an androgen, which controls normal sexual development in men.
Testosterone is essential for the development and maintenance of the male reproductive organs as well as other male characteristics, such as hair growth, deep voice, sexual drive, muscle mass and body fat distribution.
Proviron is for use in male patients only.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
