Birth control is a way for men and women to prevent pregnancy. There are many different methods of birth control; some types also help protect against sexually transmitted diseases, or STDs. Depo-Provera does not protect against STDs.
Depo-Provera is a birth control method for women. It is made up of a hormone similar to progesterone and is given as an injection by a doctor into the woman's arm or buttocks. Each shot provides protection against pregnancy for up to 12 to 14 weeks, but the shot...

A spermicide film or suppository is inserted
deep into the vagina using a finger and is placed close to the cervix. Film or
suppositories must be inserted at least 15 minutes before having sex to allow the spermicide to spread in the

and a condom used together provide a reasonable level of
birth control without a prescription. Using spermicide alone is not recommended
because it offers poor pregnancy prevention and does not protect against
sexually transmitted infections (STIs). In fact, the
nonoxynol-9 in most spermicides may increase the risk of getting HIV/AIDS from
an infected partner.
Effectiveness in preventing pregnancy
effective strength spermicide contains at least 100 mg
of nonoxynol-9 per dose. You are more likely to get pregnant if you use a
weaker spermicide. There is no difference in effectiveness between various
spermicide types, such as gel, film, or suppository.1
Typical use failure rate includes all
possible users, including people who are careless and those who use a method
perfectly every time. Perfect use failure rate includes
only people who use a method perfectly every time.
Spermicide used alone has a high failure rate
of 28% for typical users. This means that in 1 year, 28 out of 100 women who
use spermicide as their only method of birth control get pregnant. The perfect
use failure rate is still high, at 18% (18 out of 100 women).2
Spermicide used with another barrier method
(condoms, diaphragm, or cervical cap) is more effective at preventing pregnancy
than spermicide alone. For example, spermicide with a diaphragm has an average
failure rate of 12%. This means that in a year, 12 out of 100 women who use a
diaphragm and spermicide together get pregnant. The perfect use failure rate is
much lower, at 6% (6 out of 100 women).2
Vaginal douching is not considered a birth control method
even if it is done with spermicides. Douching after intercourse does not
prevent sperm from reaching the fallopian tubes, where fertilization takes
