The Reproductive System
By Jennifer Kenny
1
Human reproduction is the process of producing a
new human being. This new human is created through the
combining of a human sperm and egg. Let's take a closer
look at the male's reproductive system.
2
The male reproductive system has two very
important jobs. First of all, it produces sperm. Second
of all, it delivers the sperm to the female reproductive
system.
3
Sperm are produced in the male body in the testes. Men have two testes,
which rest in the scrotum, a sac that hangs from the body. Each testis has tubes
called seminiferous tubules where, beginning at puberty, several hundred million
sperm are produced each day. The sperm are stored and mature in the epididymis.
Another tube passes from each epididymis into the body. It is called a vas
deferens. The sperm swim through this tube and mix with fluids from several
glands, creating a mixture called semen.
4
In order for the sperm from the male to join with an egg from the female, the
sperm has to leave the male body. In order to do that, the semen goes from the
vas deferens into the urethra. The urethra in a male runs through his penis. The
penis is a male organ that has two roles. It removes urine as part of the excretory
system. In terms of the reproductive system, the penis's job is to release semen
into the female's reproductive system during sexual intercourse. The two
functions of the penis (urination and ejaculation) cannot occur at the same time.

Reproduction is the process of producing a new
human being. This new human is created through the
joining of a human sperm and egg. Let's take a closer
look at the female portion of the reproductive
system.
2
The female reproductive system has three very
important jobs. It produces eggs. It nurtures
fertilized eggs, and it gives birth.
3
Every female has two ovaries that produce eggs. Did you know that these two
ovaries contain all of the eggs a female will ever have when she is born? That's
usually around two million. The ovaries are found in the pelvic area between the hip
bones. The ovaries also produce estrogen, a hormone that causes the reproductive
organs to mature, and progesterone, another hormone that helps to regulate the
system.
4
After a girl enters puberty, the eggs in the ovaries mature, usually one each
month. An egg matures and becomes a large cell. During ovulation, the egg passes
through the ovary wall into the fallopian tube. There is one fallopian tube leading
from each ovary to an organ called the uterus. When a woman is pregnant, the baby
grows in the uterus.
5
Each month, the uterine lining thickens in case of pregnancy. If a female has
sexual intercourse that results in fertilization, the zygote embeds in this lining.
After nine months, the baby is born by going from the uterus through the vagina.
6
The vagina has three roles. It receives sperm from the male during sexual
intercourse. It is the part of the body where a baby can be delivered. It also
allows the menstrual flow and urine to leave the body.
