When talking about birth control methods, you must have heard about different methods. Birth control pills, condoms, and IUDs are very popular in our country. But have you heard of the method called 'Spermicide'? Simply put, this is a birth control method that contains a chemical substance that kills sperm. These come in different forms like gel, cream, foam, film, or suppositories. When these are inserted deep into the vagina before sex, they stop the sperm from reaching an egg. Today, we will talk about everything in detail.
How does spermicide work?
Spermicide contains a chemical that damages sperm. Most often, this chemical is Nonoxynol-9 (N-9) . Rather than actually killing sperm, it actually slows down their movement, making it difficult for them to swim to an egg.
Imagine, this is like a security guard.
1. Blocks the entrance to the uterus: When placed deep in the vagina, near the cervix, it creates a physical barrier to sperm entering the uterus.
2. Impairs sperm motility: The chemical it contains causes sperm to lose their ability to swim.
The most important thing is that for this method to work properly, you must follow the instructions on the package exactly . If you use it incorrectly, you will not get any results.
How successful is this method?
Now you're probably wondering, 'How reliable is this?' In fact, spermicide alone is only about 70% effective at preventing pregnancy. That means it's not a very reliable birth control method when used alone.
Consider this: Out of 100 women who use this method alone, about 30 will get pregnant within a year. That's why many people use it in combination with another form of birth control. For example, using spermicide with a condom is very effective. So, it's best to think of spermicide as an extra layer of protection.
Types of spermicide and how to use it
Spermicide comes in different forms. You can choose the type that is most convenient for you. Always wash your hands thoroughly before using it and read the instructions on the package carefully.
| Spermicide type | Description and how to use |
|---|---|
| Gel, cream or jelly | These usually come in a tube and have an applicator (like a tampon) to insert into the vagina. Fill the applicator according to the instructions and insert it deep into the vagina. It also acts as a lubricant. It should be applied 10-15 minutes before sex. |
| Foam | These come in an aerosol can. Shake the can well before use. Insert the applicator into the vagina. This type usually only works for 30 minutes. |
| Suppository | This is like a small pill. When inserted into the vagina, it melts at body temperature. You need to insert it close to the cervix and wait 10-15 minutes for it to melt. |
| Condoms with spermicide | Some condoms have spermicide on the outside. This provides the protection of two birth control methods at once. However, they are more expensive than regular condoms and can expire quickly. |
| Film | This is a small, thin film. When inserted deep into the vagina, it dissolves completely. It takes at least 15 minutes to dissolve, so you should have sex only after that. |
| Sponge | This is a soft, small sponge that contains spermicide. It needs to be moistened with water and inserted into the vagina. The advantage of this is that it can be inserted up to 24 hours before sex. However, it is not recommended to remove the sponge until at least 6 hours after sex. |
There is also a new type of birth control gel called *Phexxi®*. It also works like spermicide. But you need a prescription to get it.
What are the advantages and disadvantages?
Like any other, spermicide has both advantages and disadvantages.

Does spermicide protect against sexually transmitted diseases?
No. This is very important. Spermicide does not provide any protection against sexually transmitted infections (STIs).
In fact, the chemicals in spermicide can sometimes cause minor injuries and inflammation in the vagina. When this happens, the chances of infection entering the body increase. The best way to protect yourself from sexually transmitted diseases is to use a condom.
What happens if you swallow spermicide?
Spermicide is never safe to swallow. The chemicals in it can be dangerous if ingested. They are designed for external use only. Therefore, you should be very careful if you engage in oral sex after using spermicide.
When should you see a doctor?
If you are a spermicide user and experience any of the following symptoms, see your doctor immediately .
- Vaginal discharge that has a foul odor or is of a strange color.
- Rash, blisters, or sores in or around the vagina.
- Pain or burning when urinating.
- Fever or chills.
- Lower abdominal pain.
- Feeling pain during sex.
If this happens, spermicide may not be right for you. Depending on your health condition, your doctor may recommend another birth control method that is more suitable for you.
