Effect of a nonsteroidal gametic factor linked to DNA on senile cataract in man.

Abstract
In view of the results obtained in animal experiments [bovine], the effects of administering partially purified gamete [bovine sperm] extracts to elderly patients with lens opacities was studied. Of 12 patients treated orally or parenterally 10 showed, on subjective and objective evaluation, a significant increase in vision, a clearing of the opacity of the lens and an improvement of general mental and physical conditions.
