Definition
Male condoms are thin sheaths of latex (rubber), polyurethane (plastic), or animal tissue that are rolled onto an erect penis immediately prior to intercourse. They are commonly called "safes" or "rubbers." Female condoms are made of polyurethane and are inserted into the vaginal canal before sexual relations. The open end covers the outside of the vagina, and the closed ring fits over the cervix (opening into the uterus). Both types of condoms collect the male semen at ejaculation, acting as a barrier to fertilization. Condoms also perform as barriers to the exchange of bodily fluids and are subsequently an important tool in the prevention of sexually transmitted diseases (STDs).
Purpose
Both male and female condoms are used to prevent pregnancy and to protect against STDs such as human immunodeficiency virus (HIV), gonorrhea, chlamydia, and syphilis. To accomplish these goals, the condom must be applied and removed correctly.
Precautions
Male and female condoms should not be used together as there is a risk that one of them may come off. The male condom should not be snug on the tip of the penis. A space of about 0.5 in should be left at the end to avoid the possibility of it breaking during sexual intercourse. The penis must be withdrawn quickly after ejaculation to prevent the condom from falling off as the penis softens. The condom should therefore always be removed while the penis is still erect to prevent the sperm from spilling into the vagina.
Description
Male condoms made from animal tissue and linen have been in use for centuries. Latex condoms were introduced in the late 1800s and gained immediate popularity because they were inexpensive and effective. At that time, they were primarily used to protect against STDs. A common complaint made by many consumers is that condoms reduce penis sensitivity and impair orgasm. Both men and women may develop allergies to the latex. Consumer interest in female condoms has been slight.
Male condoms may be purchased lubricated, ribbed, or treated with spermicide (a chemical that kills sperm). To be effective, condoms must be removed carefully so as not to "spill" the contents into the vaginal canal. Condoms that leak or break do not provide protection against pregnancy or disease.
If used correctly, male condoms have an effectiveness rate of about 90% for preventing pregnancy, but this rate can be increased to about 99% if used with a spermicide. (Several types of spermicides are available; they can be purchased in the form of contraceptive creams and jellies, foams, or films.) Benefits associated with this type of contraceptive device include easy availability (no prescription is required), convenience of use, and lack of serious side effects. The primary disadvantage is that sexual activity must be interrupted in order to put the condom on.
Female condoms, when used correctly and at every instance of intercourse, were shown to prevent pregnancy in over 95% of women surveyed over the course of six months. When used inconsistently, the female condom was shown to have a failure rate of 21% in the same study. One benefit of the female condom is that it may be inserted immediately before sexual intercourse or up to eight hours prior, so that sexual activity does not need to be interrupted for its insertion. One study performed by a manufacturer of 
the female condom indicated that 50-75% of couples in numerous countries found the barrier acceptable for use.
A condom is most effective when it is placed on the penis correctly without trapping air between the penis and the condom.

Key terms
Ejaculate — To expel semen.
Semen — The thick whitish liquid released from the penis during sexual intercourse. It contains sperm and other secretions.
Sperm or spermatozoa — The part of the semen that is generative—can cause fertilization of the female ovum.
Spermicide — An agent that is destructive to sperm.
Vagina — The genital canal in the female, leading from the vulva to the uterus.
Condoms provide better protection against STDs than any other contraceptive method. One study conducted in the 1990s indicated that out of 123 couples with one HIV-positive partner, not one healthy individual contracted the disease when condoms were used with every instance of sexual intercourse. A similar 1993 study showed that out of 171 couples with one HIV-positive partner, all but two individuals were protected against HIV transmission with condom use. In addition to HIV, condoms provide effective transmission against gonorrhea, chlamydia, syphilis, chancroid, and trichomoniasis. A measure of protection is also provided against hepatitis B virus (HBV), human papillomavirus (HPV), and herpes simplex virus (HSV).
Before purchasing a condom, check the expiration date. Prior to use, examine the condom for holes. If a lubricant is going to be used, it should be water soluble because petroleum jellies, such as Vaseline, and other oil based lubricants can weaken latex. It is also important to note that condoms made from animal tissue or plastic are not recommended as a protection against STDs.

Patient discussion about condom.
Q. What are the chances of pregnancy even when a man uses a condom? i'm not sexually active, just sexually curious if you will. is there a statistic any where? what are the chances of pregnancy even if a man uses a condom, and what factors affect those chances? thanks.
A. Condoms are 93-97% effective when used properly. So your chances are 3-7%. If the condom breaks, has a hole, or comes off, obviously your chances increase, but none of those senarios are built into the 3-7%.
Q. Is it safe to have sex with a woman with cancer of the uterus? My 45-years old wife was told she have cancer in the uterus, and will have an operation soon. Meanwhile, should we use a condom during sex? Can the tumor pass from her to me (like AIDS or HPV)?
A. unless the cancer has lots of bleeding, you don't need to use condoms.
but if your wife would undergo an operation, maybe you need to be off-of-that-sex 1-2 days prior to operation day, just to make sure there's no super infection that will bother the operation plan.

Q. How bad can a infection get in your body? Like if you react to something like condoms and dont get it treated. I had a reaction a year ago to 3 condoms that were used and I didnt get it treated,not everything is weird in my area. Like, im all papery down there and stuff like that. And please dont say go to the doctor because that doesnt help me at the moment, because right now, thats impossible to do and please dont ask why. Thank you.
A. what you describes sounds like you had an allergic reaction to latex. an infection might be caused afterwards- if the skin ruptured. because i can't look (and please refrain adding or sending a picture- my wife can understand it the wrong way :) ) i can't really tell you if it looked infected...do you see puss? in not- get a moisturizer and use frequently. if there is an infection- there are antibiotic creams but they need a Dr. prescription if i'm not mistaken.
