_____ are glands that produce sex hormones and generate ova in females and sperm in males.
The hypothalamus is located in the brain. It produces hormones that control the other structures in the endocrine system. The amount of these regulating hormones stays about the same, but the response by the endocrine organs can change as we age. The pituitary gland is also located in the brain. The ovaries and testes have two functions. They produce the reproductive cells (ova and sperm). They also produce the sex hormones that control secondary sex characteristics, such as breasts and facial hair. With aging, men sometimes have a lower level of testosterone. Anatomy of the Endocrine System Topic Guide. Anatomy of the Endocrine System: The endocrine system is made up of glands that produce and secrete hormones. The glands that make up the endocrine system include the hypothalamus, pituitary, thyroid, parathyroid, adrenal, pineal, reproductive, and the pancreas. Aging changes in hormone production. The endocrine system is made up of organs and tissues that produce hormones. Hormones are natural chemicals produced in one location, released into the bloodstream, then used by other target organs and systems. Hormones control the target organs. LH stimulates production of the sex hormones (androgens) by the Leydig cells of the testes. It is also called interstitial-cell-stimulating hormone. The most widely-known androgen in males is testosterone, which promotes the production of sperm and masculine characteristics. home > thyroid & metabolism center > thyroid & metabolism a-z list > anatomy of the endocrine system article > anatomy of the endocrine system topic guide.

These hormones encourage the development of sperm cells within the testicles, which then produce inhibin and inhibit the production of GnRH, FSH and LH in a negative feedback loop. During puberty, in both males and females, the hypothalamus produces gonadotropin-releasing hormone (GnRH), which stimulates the production and release of follicle stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. 1 The male gonads, or testes, produce sperm within the seminiferous tubules; the sperm are housed here until they are nearly mature, at which point they enter the epidydimis for full maturation.  The testes are housed in the scrotum, an external sac that keeps the sperm at a temperature lower than that of the body. Regulation of the Female Reproductive System. In females, FSH stimulates development of egg cells (or ova) in structures called follicles. Follicle cells produce the hormone inhibin, which inhibits FSH production in the female reproductive system.
The ovaries and testes.
