Why would men not be willing to take the male contraceptive pill?

I'm a pharmacy student, and during a recent class we were discussing the possibility of the male contraceptive pill. My professor asked the males in the class if they would, to my surprise only 1/3 put their hands up. Please keep in mind you can still ejaculate, but what else would make it emasculating? Just trying to understand.

@BridgeOvertroubledWaters I can't remember of the top of my head as it was not the focus. But I believe they govern it via testosterone and FSH levels. So, you may have increased hair growth, headache, acne etc. Nothing too serious.
