Reproduction System - Females/Males

The reproduction system in males and females is responsible for the production of hormones as well as the process of reproduction.

Males

One of the most important organs of the make reproductive system are the testicles. They are enclosed in a sack known as the scrotum. The scrotum helps keep the testicles at a temperature lower then body temperature. This is important because the sperms are produced in the seminiferous tubules located in the testicles.

The epididymis is a system of convoluted tubes that connects the testicles to the vas deferens. The epididymis is responsible for emptying the sperm into the vas deferens. The vas deferens is connected to the seminal vesicle and the prostate gland. The seminal vesicle and the prostate gland release secretions that mixes with the sperm to create semen. The ejaculatory duet carries the sperm into the urethra located in the penis.

The penis contains erectile tissue and becomes erect while being aroused.

The cowper's gland located at the base of the penis prepares the urethra for ejaculation of semen.

Female

The female reproductive system is the counterpart of the male reproductive system. The outer genitals consists of the labia major and the labia minora. The clitoris, like the penis, contains recital tissue. Just like how males have two testicles, females have two ovaries. The ovaries produce hormones such as estrogen and progesterone.

The follicles in the ovaries produce eggs. Every month one egg enters the uterine tube and travels to the uterus. Every month, the lining of the uterus is nourished with blood or other liquids for preparations of receiving a fertilized egg. If the egg is not fertilized, it is discharged from the uterus along with the lining. This monthly "discharge" is known as menstruation.

The uterus is connected to the vagina and the cervix. During sex, the semen from the male penis enters the vagina. The sperm cells then travel to the tube in order to fertilize the egg. However, it is possible for only one sperm cell to penetrate the egg and fertilize the egg.

The genetic material from the sperm and egg combine to form the first cell of the zygote. The egg then travels to the uterus then it attaches itself to the endometrium. The fertilized egg then turns into a baby over time, usually around 40 weeks.

Child Birth

During child birth, the baby is pushed through the cervix then through to the vagina. The vagina becomes the birth canal for the baby.
