Correct Answer: Pituitary gland

Solution : The correct answer is Pituitary gland

The pituitary gland, sometimes known as the "master gland," is an important participant in the regulation of sex hormones in the human body. While it is not a direct source of sex hormones, it does play an important role in their production and regulation. The pituitary gland secretes hormones that stimulate the gonads (male testes and female ovaries) to create sex hormones. The pituitary gland in males secretes luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which stimulate the testicles to create testosterone. In females, the pituitary gland also secretes LH and FSH, which regulate the menstrual cycle and the ovaries' synthesis of oestrogen and progesterone.
