Contraceptive sponge
The contraceptive sponge is a
flexible, saucer-shaped device made of polyurethane foam. It is considered a
barrier method of contraception.
How it works?
It is designed to be worn over
the cervix and works in three ways to prevent pregnancy:
- It blocks the cervix, preventing sperm from entering the uterus.
- The sponge contains a spermicide that kills sperm.
- Sponge absorbs sperm.
How effective is the contraceptive sponge?
When used correctly and
consistently, it has a failure rate of about 9%, or almost 1 in 10. The typical
use of a contraceptive sponge refers to how most people use it. The failure
rate in normal use is approximately 16%. You must take a pregnancy test if you
have symptoms of pregnancy.
What are the side effects or health risks of contraceptive sponges?
The sponge has been linked to
some women suffering from toxic shock syndrome, a rare but serious bacterial
infection that can be fatal.
The sponge should not be left
in the vagina for more than 30 hours. The sponge should not be used during
menstruation or if there is a history of toxic shock syndrome.
Is the contraceptive sponge reversible?
Yes. Does not affect the
reproductive function of the male or female. Pregnancy is possible when you
stop using it.
What about sexually
transmitted diseases?
It does not protect against
the transmission of sexually transmitted diseases.
