Quizplus · Accepted Answer

Sperm production in males at puberty is regulated by a combination of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone secreted by the testes. LH and FSH are secreted by the pituitary gland and have a direct effect on the testes to stimulate testicular growth and sperm production.

Estradiol, a form of estrogen, is not a primary regulator of sperm production in males.
