Anorchi.

Anorchia was diagnosed in 3 patients after a hormonal study entailing the basic determination of FSH, LH and testosterone by a radioimmunoassay technique and by later stimulation with HCG. 2,000 IU are administered during 3 consecutive days with a new testosterone determination 24 and 72 h after the last administration. If the result is negative, the test is repeated but the HCG dose is doubled. A new negative response confirms the diagnosis of anorchia. If the results are positive a spermatic phlebography allows localization of the testicles or the remains of Wolffian origin in order to simplify surgery.
