Effect of gossypol on testicular testosterone production in vitro

N. R. Kalla, G. F. Weinbauer, E. Rovan and J. Frick

Testicular minces were utilized to study the effect of gossypol on testosterone production. Testosterone production was assessed in both control nd gossypol treated groups after 0 to 4 hours incubation in the presence of hCG. Media testosterone was measured by radioimmunoassay. Gossypol did not alter testosterone production when present in incubates at the concentrations of 3.5 x 10(-5) M, 7 x 10(-5) M and 3.5 x 10(-4) M. Preincubation of testis mince with gossypol (7 x 10(-6) M, 7 x 10(-5) M, 3.5 x 10(-4) M) for 1 to 4 hours did not alter subsequent hCG induced testosterone production in mature rats. Testosterone production however, was inhibited in immature rat testis when the whole testis was incubated for 4 hours with different concentrations of gossypol (7 x 10(-6) M, 7 x 10(-5) M, 3.5 x 10(-4) M). In vivo testosterone production was not inhibited in the immature rat testis 24 hours after oral administration of gossypol (100 mg/kg).
