Introduction
The condom is a barrier device that is used since ancient times. Many couples do not want to get pregnant but still want to have sexual intercourse. In this circumstance, one way is to wear a condom. AIDS (Acquired Immunodeficiency Syndrome), is a pandemic that caused 36 million deaths worldwide (citation: UNAIDS.org, 2012) caused by HIV (Human Immunodeficiency Virus). One of the reasons why it spread so quickly is because of sexual contact. The men’s body fluid (semen) is spread into the women’s body, which means the woman is also contracted with AIDS. But with the help of the condom, the number of people newly infected by AIDS greatly reduced. The condom does not stop AIDS, it stops AIDS from spreading.

Throughout history, there are many different types of condoms, from the earliest leather condoms, to rubber, and now the Polyisoprene (Natural rubber). The most commonly used is the 1920 Latex Condom, which is the one I will focus on in this essay. How the condom works
Human reproduction works when an erect penis is inserted into the vagina and the man thrust it in and out until ejaculation occurs. The semen (liquid that includes sperm and other liquid) is released into the vagina. The sperm travels along the vagina and meets the egg, where the sperm fertilizes the egg. The sperm and egg forms a zygote. The zygote later forms into an embryo cell and is implanted onto the endometrium (the uterus wall); this is the beginning of pregnancy. (Y9 Reproduction
