Final answer:
The thyroid gland does not secrete hormones involved in the menstrual cycle.
Step-by-step explanation:
The correct answer is d) Thyroid gland.
The menstrual cycle is regulated by hormones produced by the hypothalamus, pituitary gland, and ovaries. The hypothalamus secretes gonadotropin-releasing hormone (GnRH), which stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH and LH then act on the ovaries to regulate the development and release of an egg, as well as the production of estrogen and progesterone.
While the ovaries, uterus, and pituitary gland all play important roles in the menstrual cycle, the thyroid gland is not directly involved in the regulation of hormones involved in the menstrual cycle.
