In the 1986 Rockefeller Foundation annual report, the organization admits funding research into the use of fertility-reducing compounds in relation to food for “widespread use”:
“Male contraceptive studies are focused on gossypol, a natural substance extracted from the cotton plant, and identified by Chinese researchers as having an anti-fertility effect on men. Before widespread use can be recommended, further investigation is needed to see if lowering the dosage can eliminate undesirable side-effects without reducing its effectiveness as a contraceptive. The Foundation supported research on gossypol’s safety, reversibility and efficacy in seven different 1986 grants.”
