Basal serum LH and FSH values were found to be within normal limits in 9 homosexual men. The mean LH and FSH responses following the intravenous administration of 100 microgram of LRH were not significantly different from that of heterosexual controls. In addition, the mean basal plasma serum testosterone was similar in the two groups. There is thus no definite implication of endocrine factors in the genesis of male homosexuality.
