Androgen insensitivity suspected by estimation of serum hormone levels in oligozoospermic and azoospermic men.

According to higher androgen insensitivity index than in fertile men, the group of 83 men, with high serum LH and high or normal testosterone levels, was separated from 800 infertile men. These patients with high androgen insensitivity index had oligozoospermia (6.38 +/- 3.18 X 10(6)/ml) or azoospermia. They had significantly higher serum LH and testosterone levels than compared groups of infertile and fertile men. Elevated serum FSH levels in infertile men with high androgen insensitivity index showed damage of spermatogenesis. There was completely disturbed hypothalamo-pituitary-testicular axis as the serum prolactin levels were significantly elevated too. There was no significant difference in serum estradiol levels among investigated groups. Using androgen insensitivity index we could identify those men whose infertility is not treatable.
