The male reproductive system works to create sperm and then release it into the female during sexual intercourse. The organs in the system are the testes, the epididymides, hanging in a skin bag called the scrotum, the sperm ducts, the prostate gland, and the penis containing the urethra. The testes are also known as sperm glands. They make tiny sperm cells called spermatozoa. They also produce hormones especially testosterone (this activates the production of sperm cells). Epididymides are tightly coiled tubes on each side of the testes. They help sperm become mature. The sperm ducts carry fresh sperm towards the outside. The ducts join with the urethra inside of the prostate. The urethra carries the sperm through the penis to the outside. This pathway is also known as the male reproductive tract.
The parts of the female reproductive system work together to produce pin- head size eggs that join with a male's sperm to fertilize one of the eggs. The system nourishes the egg until it forms a full-grown baby. Then, once the baby is born, it produces milk for the baby. The main parts of a female reproductive system are the ovaries, the oviducts (also called the fallopian tubes), uterus (womb), vagina, vulva and the breasts (where the milk for the baby is released). The ovaries are called "egg glands". They store tiny eggs called ova. These will develop into a baby, if a man's sperm fertilizes them. The ovaries also produce hormones. The two oviducts each link the two ovaries with the uterus. They carry the ripe eggs to the uterus. When a male fertilizes a female's egg, it usually occurs in the oviduct. The uterus is where the fertilized egg grows and is nourished until it is ready to come out. At first, the uterus is about the size of a baseball or a tennis ball.
By the time the baby is fully developed, it is about the size of a basketball. When the baby is coming out, it goes through the neck, or the cervix and passes out the vagina to the outside. This process is known as the female reproductive tract.
The most important event in reproduction is fertilization. The male's sperm and the female's egg join together in the woman to form one cell called the fertilized egg. This egg forms a complete set of genes. This process of fertilization is called conception, or conceiving a baby. Sperm cells flutter around the egg. One sperm cell breaks through the membrane of the egg. Then the sperm genes link with the egg genes. A thick barrier called the zona pellucida forms around the fertilized egg to keep out the other sperm.
The reproductive system is one of the most important systems of the human body. It continues the human race. Without the reproductive system, nobody would be walking or eating right now. The reproductive system produces human offspring. One of the most known diseases of the reproductive system is prostate cancer. Prostate cancer occurs when the cells of the prostate begin to grow and divide uncontrollably. The key parts of the reproductive system are the male system, the female system and the developing embryo. The reproductive system is a very important system in the human race.
