The testes produce testosterone in men, help maintain muscle and bone mass, help produce sperm and support the sex drive, according to Hormone Health Network. Found in women, the ovaries produce estrogen and progesterone and help to maintain healthy menstrual cycles.Continue Reading
Located in the scrotum, the testes are outside of the body to keep temperatures lower, says Better Health Channel. The testes make sperm, which requires a slightly lower body temperature to thrive. The testes are part of the male reproductive system, producing the androgen testosterone that helps the penis grow and leads to facial and body hair as well as the deepening of the voice.
The ovaries secrete hormones responsible for regulating the menstrual cycle, says Better Health Channel. As part of the female reproductive system, the ovaries produce the hormone estrogen to thicken the lining of the uterus, or endometrium.
At a mid-point in the menstrual cycle, the ovaries release an egg, explains Better Health Channel. If the egg is unfertilized, the ovaries do not produce the hormone progesterone in adequate supply, and the endometrium begins to be expelled from the body. If the egg is fertilized, it lodges in the endometrium. Unlike men, who produce sperm continuously throughout their lives, women are born with their entire egg supply.Learn more about Organs
According to the University of Rochester Medical Center, the primary functions of gonads in men and women are to secret hormones and to produce sperm and ova. In men, the gonads are the testes, and in women, the gonads are the ovaries. The gonads are considered endocrine glands because they release hormones.Full Answer >
The stratum granulosum functions as the waterproofing layer of the skin that prevents fluid loss, according to the Loyola University Medical Education Network. Keratin accumulates in this layer by a process that forms a thicker layer of skin cells to protect less dense cells underneath. Lipids and keratin organize as flat skin cells without their nuclei, according to Dr. Heather Brannon for About.com.Full Answer >
The organs of the female anatomy include the cervix, vagina, uterus, ovaries and the Fallopian tubes. As part of the female reproductive system, these organs produce the female egg cells, which are called ova or oocytes, that are necessary for reproduction to occur and transport the cells to the fertilization site.Full Answer >
The terms "testis" and "testicle" are often used interchangeably, though technically the testicle includes not only the testis but also the vas deferens and the epididymis, which are two tubular structures that serve to store and transport sperm. The testes themselves are made up of hundreds of tiny coiled tubules called "seminiferous tubules," which are the site of sperm cell generation.Full Answer >
