The male reproductive system is a series of organs located outside and in the pelvis region. The main purpose of the male reproductive system is to provide sperm to fertilize the egg. The main parts of the male are the production and storage of sperm. The first category is sperm production and storage. Sperm production occurs in the testicles. The sperm that is not the ejaculatory fluid that produces the glands that include the still developed travels to the duct behind the testicle where it is kept and allowed to mature. The actual glands for sperm production consist of the seminal vesicles, the prostate and the vas deferens. Finally, there are those used for sex and sperm deposition, these include the penis, urethra, vas deferens, and Cowper's gland.

The external structures of the female system consist of the clitoris, labia majora, labia minora and Bartholin's glands. The main internal organs of the female reproductive system include the vagina and uterus which act as a receptacle for sperm, and the ovaries, which produce the female eggs which are the egg cell. The vagina is connected to the uterus through the cervix, the fallopian tubes connect the uterus to the ovaries. During hormonal changes, the female's uterus releases an egg that travels down the fallopian tubes. If the eggs are not fertilized by sperm, they are shed during menstruation. However, if the sperm manages to penetrate the egg, the fertilized egg attaches to the lining of the uterus where embryogenesis (when the embryo forms) and morphogenesis (when the fetus begins to take shape) begins. When the fetus is fully developed, the uterus begins to come into contact and the cervix dilates to allow the fetus to be expelled through the birth canal. The reproductive system works with the nervous system because reproductive hormones influence brain development and sexual behavior, even the brain. controls mating behavior the reproductive system interacts with the endocrine system to promote maturation and maintain sexual functions, for example in males testosterone contributes to sexual desire and function while estrogen contributes to the female's ability to have children. The circulatory system maintains tissues and provides physical mechanisms for arousal. The erectile tissue of the penis and clitoris relies on the circulatory system.
