Overview
Laboratory Findings
Hormone tests, including checks of blood levels of estrogen, FSH, LH, testosterone, and thyroid, prolactin. These tests can help doctors identify the cause of hypogonadism.
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.
