Spermicides are available in various forms, including:. They can be used alone or in conjunction with other types of birth control, such as a cervical cap or diaphragm. Spermicides do not protect against sexually transmitted diseases STDs. When used alone, spermicides are among the least effective methods of birth control available, with 28 percent of those sexual encounters resulting in pregnancy.
Spermicidal condoms:. The spermicide used on spermicidal condoms, nonoxynol-9, can cause allergic reactions in some people as well. Symptoms include temporary itching, redness, and swelling. It can also cause urinary tract infections in some women. Because spermicide can irritate the penis and vagina, contraceptives containing nonoxynol-9 may increase the risk of HIV transmission.
This risk increases if spermicide is used multiple times in one day or for several consecutive days. If you experience irritation, discomfort, or an allergic reaction, changing brands may help.
It may also make sense to try other forms of birth control. If you or your partner is HIV positive, spermicidal condoms may not be the best birth control method for you. Read more: Which birth control is right for you? If you conceived while using spermicidal condoms or any other type of spermicidal birth control, the fetus will not be harmed as a result.
No one type of birth control, other than abstinence, is percent effective at preventing unwanted pregnancy or the spread of STDs. Some types are more effective than others, however. For example, female birth control pills are 99 percent effective when taken perfectly, although this rate goes down if you miss a dose.
Male and female condoms are the only type of birth control that also helps to prevent STDs. Either one can be used alone or in conjunction with other forms of birth control, such as spermicide.
This springy design helps to hold the diaphragm in place in conjunction with your pelvic floor muscles in the vagina. Once the diaphragm is correctly in place, deep in the vagina, covering the cervix appropriately, the user should not be able to feel it. On the note of sensation, one benefit to the diaphragm over condoms is that there is more sensation for both partners having penetrative sex as it does not cover the penis.
The diaphragm however does not protect against sexually transmitted infections as condoms do. Diaphragms are totally safe to use with breastfeeding or for people who have medical conditions that exclude them from using hormones as they are hormone-free. There is a small opening in the cervix known as the cervical os. The os is where sperm enter the uterus and fallopian tubes to meet an egg for fertilization and pregnancy. Ever wondered what in the heck a cervix looks like?
Check out this article that shows photos of a cervix through a typical cycle. Each diaphragm will have slightly different instructions but the basics are the same.
I really like this planned parenthood article on how to use a diaphragm correctly. Below is the verbal description I give my patients during an appointment when prescribing them. You may insert your diaphragm in conjunction with spermicide up to two hours prior to sex. Removing it any earlier increases your risk for pregnancy, as sperm may still be alive and able swim up into the uterus to find an egg. Do not leave the diaphragm in for more than 24 hours.
Diaphragms should not stay in the vagina for more than 24 hours. Leaving them in for longer increases your risk for toxic shock syndrome. This is rare and unlikely but does occur. Read the link about TSS toxic shock syndrome and keep an eye out for any signs or symptoms in your own body.
If you have any of these symptoms call your doctor or go to the emergency room right away. When you have removed the diaphragm from the vagina after sex , rinse it with warm water and a gentle, mild soap and let it air dry either on a paper towel or in the case with the lid open.
Do not store the diaphragm wet in the case and do not apply any powder to the diaphragm. As long as they are water-based. DO NOT use any oil-based lubes such as coconut oil, or silicone-based lubes which are increasingly popular as these two types can break down the diaphragm and make it less effective.
To be safe, check the ingredients on the lube you buy from the store or online before using anything in conjunction with your diaphragm during sex. In general when confronting the effectiveness of your birth control method and making a decision that feels right for you , I always recommend choosing a method that matches your comfort level and needs when it comes to the chance of getting pregnant.
Using a spermicide or condoms that contain it can also cause yeast infections in some women. Nonoxynol-9, the active ingredient in most spermicides , kills sperm and germs but can be irritating and kill good bacteria, too. Good evidence shows that spermicides will not cause birth defects or otherwise harm the fetus if a woman becomes pregnant while using spermicides or accidentally uses spermicides when she is already pregnant.
Spermicides , especially gels and jellies, provide some lubrication during sexual intercourse. Oil-based products such as hand, face, or body cream; petroleum jelly; cooking oils or shortenings; or baby oil should not be used because they weaken the latex rubber. The citric acid in lemons acts as a natural spermicide. The lemon rind itself with pulp and juice removed could also be inserted into the vagina and used as a cervical cap.
Can you use spermicide alone? Category: medical health birth control. Spermicide can be used alone or with a barrier method — such as a condom, diaphragm or cervical cap — to prevent pregnancy. You insert spermicide in the vagina before sex. The chemicals in the spermicide , such as nonoxynol-9, prevent sperm from entering the uterus. You can get spermicide over-the-counter.
