What hormones block androgen production?
block androgen production (synthesis) throughout the body. Androgen production in men. Drawing shows that testosterone production is regulated by luteinizing hormone (LH) and luteinizing hormone-releasing hormone (L HRH). The hypothalamus releases LHRH, which stimulates the release of LH from the pituitary gland.
What does LHRH do to the testicles?
LHRH agonists, like the body’s own LHRH, initially stimulate the production of luteinizing hormone. However, the continued presence of high levels of LHRH agonists actually causes the pituitary gland to stop producing luteinizing hormone.
