Human and monkey spermatozoa were inhibited by gossypol to different degrees. Monkey sperm were absolutely immotile within 15 min after 50 μM of gossypol was added, but motility of human spermatozoa was not completely suppressed by gossypol even at the highest concentration used and longest duration of exposure. © 1986.Mahidol UniversityMedicineArticleSCOPUS10.1016/0010-7824(86)90013-2
