Effect of (+)-gossypol on fertility in male hamsters

D. P. Waller, N. Bunyapraphatsara, A. Martin, C. J. Vournazos, M. S. Ahmed, D. D. Soejarto, G. A. Cordell, H. H. Fong, L. D. Russell and J. P. Malone

(+)-Gossypol was isolated from the bark of Thespesia populnea and tested for its ability to inhibit the fertility of male hamsters. Male hamsters of proven fertility were treated orally for 54 days with 40 mg/kg of (+)-gossypol, 40 mg/kg of racemic gossypol, or 5% gum acacia (vehicle control) and were mated with estrous female hamsters during the fourth and seventh weeks of treatment. Both the control and the (+)-gossypol-treated animals exhibited normal fertility throughout the experiment. The racemic gossypol-treated animals were infertile when evaluated during both the fourth and seventh weeks of treatment. Morphologic examination of the testicular tissue could not explain the loss of fertility. These data demonstrate the inability of (+)gossypol to decrease male fertility and suggest that the activity of racemic gossypol may be due primarily to the presence of the (-) optical isomer.
