Question

Quizplus · Accepted Answer

The pituitary gland detects high levels of testosterone in the bloodstream, regardless of whether it is self-produced or synthetic. In response, the pituitary gland reduces the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are responsible for the production of testosterone in the testes. This decrease in hormone production can cause the testes to shrink over time.
