A researcher is studying the hormonal control of spermatogenesis. He administers a drug that selectively blocks the receptors for a specific hormone in the testes. As a result, he observes a significant decrease in the rate of spermatogenesis, but testosterone levels remain normal. Which hormone's receptors are MOST likely being blocked by the drug?
LH
FSH
Testosterone
Inhibin
