Testosterone cypionate is prescribed to male patients who are suffering from conditions that are caused by low testosterone levels in the body, such as erectile dysfunction, according to C-Health. It works by replacing the missing testosterone in the body, and it is only given when low levels have been confirmed.
Testosterone cypionate is also often prescribed to adolescent boys who have conditions related to delayed puberty, reports WebMD. Normal testosterone levels are crucial in these patients for the sound development of the skeleton, muscles and secondary sex characteristics. If a patient suspects low testosterone levels, he should consult a physician before taking any medication.
