Luteinizing hormone (LH) is produced by the anterior pituitary gland, which plays a crucial role in regulating reproductive functions in both males and females. In females, LH triggers ovulation and promotes the formation of the corpus luteum, leading to the production of progesterone. In males, LH stimulates the Leydig cells in the testes to produce testosterone.

The anterior pituitary gland is essential for the secretion of several key hormones, including LH, follicle-stimulating hormone (FSH), and growth hormone, as it is directly involved in the endocrine control of various physiological processes. Other glands mentioned do not directly produce LH: the thyroid gland primarily produces thyroid hormones which regulate metabolism; the adrenal cortex is involved in producing corticosteroids and sex hormones; and the posterior pituitary gland releases oxytocin and vasopressin, but it does not synthesize these hormones. Thus, the anterior pituitary gland is the correct source of LH, emphasizing its vital role in the endocrine system.
