Diagnosis
Low Testosterone can be identified through a simple blood test performed by a physician. Normal testosterone levels range from 298 - 1098 ng/dl. Physicians measure gonadotropins (LH and FSH) to distinguish primary from secondary hypogonadism. In primary hypogonadism the LH and/or FSH are usually elevated, while in secondary hypogonadism both are normal or low.
Hypogonadism is often discovered during evaluation of delayed puberty, but ordinary delay which eventually results in normal pubertal development and reproductive function is termed.
Treatment
Hypogonadism is most often treated by replacement of the appropriate hormones. For men this is testosterone. Commonly used testosterone formulations include transdermal testosterone, injectable testosterone, and buccal testosterone. Oral testosterone is no longer used in the U.S. because it is broken down in the liver and rendered inactive. Another feasible alternative is hCG. For women estradiol and progesterone are replaced. Some types of fertility defects can be treated; some cannot.
