Question

Quizplus · Accepted Answer

The administration of artificial testosterone leads to a negative feedback mechanism that signals the anterior pituitary to reduce the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are crucial for testicular function and development. This reduction causes the testes to shrink.
