At his clinic, Brinkley began to perform more operations he claimed would restore male virility and fertility through implanting the testicular glands of goats in his male patients at a cost of $750 per operation ($ in current dollars). Following one of his crude operations, the body of a patient would typically absorb the goat tissue as foreign matter. The goat gonads failed to engraft into the body, as they were simply placed within the human male testicle sac or the abdomen of women, near the ovaries.
