Hormone profile in infertile men.
Plasma basal levels of FSH, LH, prolactin, and testosterone were evaluated in 263 men with fertility problems. Significant increases in FSH were detected in all groups of infertile men except those with infection, varicocele, infection and varicocele, and obstructive azoospermia. No differences in LH were detected in all groups, except those with chromosomal testicular abnormality and idiopathic seminiferous tubular failure where significant increases were revealed. No differences in prolactin were detected, while a decrease was found in testosterone in the group with chromosomal testicular abnormality. FSH seems to be a most valuable hormone index in the routine workup of male infertility, while prolactin does not offer substantial information. The combined LH and testosterone evaluation might be of diagnostic importance in selected cases.
