Then again, a constant steroidal testosterone drip would cause other problems. Steroidal hormones suppress follicle stimulating hormones and luteinizing hormone, both of which stimulate the testicles. Without these hormones, the testicles shrink down. (one man who was prescribed steroids as medication described his as “ grapes ” and complained about how much loose skin was left over after they shrank) This is often reversible, but only after the steroid use stops. So even under ideal circumstances, people would have to make the choice between small testes or big breasts.
