What is this?
Spermicide is a chemical that neutralizes sperm. Most spermicides contain a chemical called nonoxynol-9. You can use spermicide by itself or with any barrier method, except for the sponge, which already includes spermicide.
Frequent use of N-9
can cause changes in the vagina and rectum, increasing the risk of contracting
HIV from an infected partner. You should only use spermicide for birth control,
whether alone or with another barrier method, if you are at low risk of HIV
infection.
Spermicides are easy
to use and widely available in many stores. They are more affordable compared
to other birth control methods and do not impact your natural hormones.
Additionally, spermicides do not affect milk supply if you are breastfeeding.
How does this work?
When using spermicide
alone, it should be inserted into the vagina near the cervix. There are various
types of spermicides:
●
Foam: Inserted with an applicator similar to a tampon
applicator.
●
Cream or Gel: Inserted with an included applicator.
●
Suppository: Solid pellets that melt after insertion.
●
Film: Thin sheets inserted with your fingers close to the
cervix.
You need to wait 10
to 15 minutes after insertion for the spermicide to take effect. Always read
the label to know how long before sex to insert the spermicide.
Spermicides are only
effective for 1 hour after insertion. If more than 1 hour passes, you need to
insert a new dose. Reapply spermicide for each act of sex. Do not douche or
remove the spermicide for at least 6 hours after insertion.
Efficacy:
The efficacy of spermicide varies based on its use. When used alone, spermicide has a typical use failure rate of about 28%, meaning 28 out of 100 women will become pregnant within the first year of use. However, when used correctly and consistently with another barrier method, such as a condom or diaphragm, the effectiveness improves significantly.
Usage duration recommended:
The usage duration of
spermicide depends on the type and the specific instructions provided with the
product. Here are some general guidelines:
Always read and follow
the specific instructions provided with your spermicide product to ensure
proper use and maximum effectiveness.
