A Condom is a very thin latex cover that fits around the penis and prevents sperm from entering into the woman’s vagina. It not only helps prevent pregnancy, but also sexually transmitted infections.
Effectivity: Like all birth control methods, condoms are effective only if you use them correctly. The effectiveness is about 98%. This means that only 2 out of 100 women whose partners use male condoms as contraception will become pregnant in one year.
Pros: There are no hormones with condoms, so no medical side effects, unless you are allergic to latex. Condoms also prevent STD transmission.
Cons: Some men may experience the lessening of sensation. Also the act of putting on the condom may break the continuity of sexual intercourse.
Diaphragms are made of latex, with a shallow, domed cup and a flexible rim that, when inserted into the vagina, covers the cervix. They work by preventing sperm from entering the cervix. One should use a diaphragm with a spermicide, which kills sperm and provides an added layer of birth control protection.
The diaphragm must be left in place for at least six hours after sex. After that time you take out the diaphragm and wash it. They're reusable.
Pros: When used correctly and in combination with spermicidal gel, the diaphragm has a birth control effectiveness rate of 94 percent. It is easy to insert and discreet to carry. It does not affect partner in any way. It is non-hormonal and so does not have any harmful effect on the body.
Cons: Some women find it difficult to insert. It is sometimes dislodged and may lead to unwanted pregnancy.
