Spermicides are on the list of "chemical" methods of contraception. These are gels, sprays, creams or vaginal suppositories / ovules capable of immobilizing or killing spermatozoa before they enter the uterus.
Key points
Let's see the general characteristics. For more information, read the dedicated article.
SPERMICIDES
- Chemicals capable of immobilizing / killing spermatozoa before they enter the uterus
- Spermicides alter the membrane integrity of spermatozoa; therefore, they make them unable to fertilize the egg.
- This contraceptive method also acts by altering the vaginal pH: in this sense, the aforementioned contraceptive method creates an environment hostile to spermatozoa.
- Combined with other methods of contraception, spermicide reduces the risk coefficient (failure of contraceptive protection)
- It does not require a medical prescription
- Increase lubrication during intercourse
- It does not involve the side effects typical of hormonal contraceptive methods
- The application of the spermicide can irritate or even damage the vaginal and rectal walls
- The routine use of this contraceptive method increases the risk of urinary tract infections and bacterial vaginosis
- It offers no protection from MST
- The efficacy of the spermicide lasts only for 60 minutes (starting from the moment of insertion / application in the vagina)
- It can create allergic reactions in both partners
- The contraceptive method requires a certain "planning" of the relationship
- When used alone, spermicide is not considered a reliable method of contraception, as it protects against unwanted pregnancy in only 71% of cases.
