Serum Hormone Levels

A routine part of the initial evaluation is a determination of blood levels of specific hormones usually including FSH, LH, testosterone, and prolactin levels. The interrelationship of these four hormones is closely tied to normal sperm production. Abnormalities may be a sign of a primary hormone problem in the hypothalamus, pituitary, or testis.
