The establishment of safe and effective fertility inhibitors for dogs must also be matched by evidence that non-surgical fertility control is an efficient, humane, and socially acceptable alternative to surgical sterilization for managing over abundant populations of dogs and their impact on human interests. The present study was undertaken to study the contraceptive effects of coumestrol in adult male dogs. Experimental group I was given 300 µg coumestrol dissolved in di-methyl sulfoxide orally in the commercial dog treats, on days 0, 7, 14, 21 and 28. Control group II was given DMSO alone as per above schedule. | Effects of coumestrol treatment on spermatogenesis in dogs
