Sometimes the common methods of birth control may not work for some women because of certain unpredicted side-effects. In such a case, one can opt for the Vaginal sponge or the Contraceptive sponge. The vaginal sponge is a means of birth control which is reversible. Some women may prefer using a vaginal sponge to avoid pregnancy as it is easily available at most pharmacies without a prescription and is fairly easy to use as well. However, a vaginal sponge when compared to a male condom may not be able to provide any protection against Sexually Transmitted Diseases (STD) like HIV.
What Is a Contraceptive Sponge?
Contraceptive sponge or the birth control sponge is a doughnut-shaped sponge, about two inches in size. This soft, round vaginal sponge is made from polyurethane foam. The female sponge helps in preventing pregnancy through the blockade and spermicidal methods.
The contraceptive sponge may be inserted deep into the vagina before sex. The sponge forms a protective cover over the cervix and stops the sperm from passing into the uterus. Every cervical sponge has an attached cloth loop which makes it convenient to pull it out. The sponge is not reusable and should be discarded after use.
How Does It Work
The working of the sponge may be similar to that of a diaphragm. The sponge birth control method works in two ways. The sponge has an indentation which allows it to fit tightly against the cervix, creating a protective barrier and obstructing the entry of the sperms into the uterus. The sponge absorbs the semen before it can enter the cervix, the connecting passage between the vagina and uterus.
The vaginal sponge also has spermicide, a sperm-killing substance which prevents sperm from gaining access to an egg. It is essential for women to follow the correct method of insertion and using the sponge before sex. The sponge has to moisten with water before being inserted deeply into the vagina. You can keep the sponge inserted into the vagina for about 24 hrs before intercourse.
After use, you can pull it out with the help of the loop fastened to the sponge. The sponge can be used either in addition to a condom or all by itself. However, using it along with a condom may offer better protection against pregnancy.
Contraceptive Sponge’s Effectiveness
Here is how using a sponge helps avert pregnancy
1.The Effectiveness of Sponge for Preventing Pregnancy
When we talk about birth control, the contraceptive sponge may not be the best method available in the market especially if a woman has given birth once. However, it is vital to use the sponge properly before sex for it to be most effective. Following the product instructions correctly and using it each time before sex may increase its efficiency. But realistically speaking, it may not be entirely possible to use it correctly every time.
If a woman who has not borne a child and accurately uses the sponge, the efficiency rate can be as high as 91%. But realistically it may not be more than 88% effective. But in the case of a woman who has given birth before, the success rate may be less than 80% even if we talk realistically. Therefore, rendering it an unlikely choice of contraception for women with kids.
So, it can safely be assumed that 9 to 11 women out of 100 on an average who use the contraceptive sponge may still get pregnant in a year.
2. Ways to Increase the Effectiveness of a Sponge
One of the ways to increase the effectiveness of sponge can be to use it properly each time before you have sex. Using the sponge consistently every single time before sex may also enhance its efficiency. But a definite way to boost its effectiveness is by using it in combination with another method of contraception like oral contraceptives or the male condom.
Another way can be if your partner does not ejaculate semen inside and pulls out before secreting the semen inside the vagina. Nevertheless, using both the sponge and the male condom together may be the most effective way.
3. Do the Sponges Protect Against STDs?
The sponge cannot offer any protection against STDs. On the contrary, the use of sponge may put you at a greater risk of STDs like HIV. The spermicide sponge effectiveness is considerably reduced because the spermicide which coats the sponge has Nonoxynol-9, a chemical compound that can irritate the vaginal walls and make it more vulnerable to STD germs for them to easily enter the body through the vagina. Therefore it is better to get yourself tested on a regular basis to prevent STDs.
How to Use the Sponge
The correct usage of sponge for effective birth control cannot be stressed enough. The sponge can be fairly easy to use once you get enough practice with it. Inserting a sponge is quite like pushing in a tampon.
1. Contraceptive Sponge Insertion
The following things may be kept in mind while using the sponge:
- It is important to wash the hands properly with water and soap before putting in the sponge.
- After removing the wrapper of the sponge, moisten it with a little water.
- Squeeze the sponge lightly a few times or until it is foamy. The sponge should be entirely wet for the spermicides to get activated.
- Take care not to squeeze the sponge dry.
- Keeping the indented side of the sponge facing upwards, turn the sides up (like you fold something in half) so that the sponge is long and narrow. The indented side of the sponge should be facing the body’s front side whereas the loop of the sponge should be facing the body’s backside.
- Try sitting in a comfortable position like you can balance yourself on a chair’s edge or squat. You can also insert the sponge while lying down or standing with one of your foot placed on a chair.
- Push the sponge deep into the vagina with the help of your fingers. Try and slide it as far up as possible. Upon letting go, the sponge will on its own unfold and tightly fit covering the cervix.
- Make sure that the sponge is covering the cervix properly by moving your fingers all over and along the edges of the sponge. Also, ensure that the loop is at the sponge’s bottom.
You need not stress over remembering every single detail. All products come with a detailed set of instructions. Following the given directions will help you use the sponge correctly.
2. When Can One Insert the Sponge?
You can put in the sponge for about 24 hours before intercourse. The sponge is ready to use as soon as the spermicide is activated with water and inserted into the vagina. Therefore, birth control can be in place much before you have sex. After the sponge is inside the vagina you can indulge in intercourse any number of times as you may want without any interruptions for the next 24 hours. You need not replace the sponge for that period.
3. How Long Can You Leave a Sponge Inside?
You need to leave the sponge in for a minimum of six hours after intercourse. But be careful not to leave it inside for beyond 30 hours in total. There is no compulsion, however, to leave the sponge inside for total 30 hours, but six hours after sex must be abided by to be on the safer side.
4. Removal of Sponge
After washing your hands carefully, glide a finger into your vagina and fasten it around the loop of the sponge. Then very gently and steadily with the help of the loop pull the sponge out of the vagina. In case you are not able to find the loop of the sponge, you can grasp the sponge itself and slowly slide it out. If you experience difficulty reaching the sponge, push or thrust down with the help of your vaginal muscles while trying to reach for it. Carefully dispose of the used sponge by throwing it in the trash bin and not by flushing it down a toilet.
