Abstract
An investigation on infertility and hormonal status was carried out in 107 subjects, aged 18-35yrs, who were operated for cryptorchidism during childwood.The group consisted of 50 bilateral and 45 unilateral cryptorchid as well as 1 subject with Klinefelter's syndrome and another with Kallmann syndrome.The sperm count results indicated that 70% of the bilateral and 20% of the unilateral subjects were infertile.There existed a good correlation between the sperm counts and the FSH values before and after LH-RH functional test.The LH values didn't demonstrate any good correlation.The response for LH and FSH after LH-RH in 6 subjects was diminished, although amongst them only 1 bilateral cryptorchid patient was infertile.Plasma testosterone recoreded a range between 69 and 737 ng/100 ml in this group and didn't correlate either to sperm counts or to the gonadotropins.The data, on one hand, show poor fertility prognosis in surgically operated cryptorchid subjects and on the other difficulties in hormonal assestment which could be responsible factors for cryptorchidism.
