Advantages and Disadvantages of Barrier Birth control methods
In our society people have become more responsible with regards to family planning. Almost each couple is using various methods of birth control. Barrier contraception is one of the most popular and common birth control methods. It was used long before oral contraceptive pills and intrauterine devices appeared. Barrier contraceptives do not allow the sperm to enter the vagina or the uterine. Both men and women can use this method. Barrier contraception today offers a great variety of products, so each couple can choose what is convenient and effective for them.
What is barrier contraception?
Barrier contraception includes the products for men and the products for women. Birth control is provided mechanically or chemically.
Among the mechanical contraceptives are:
- Male condoms;
- Cervical caps;
- Contraceptive diaphragms.
The chemical barrier contraceptives are:
- Aerosol products;
- Vaginal tablets;
- Gels or creams;
Chemical products have a spermicidal effect, it means that they are able to destroy or deactivate male sex cells. These products usually contain highly active chemical substances such as nonoxynol-9 and benzalkonium chloride. Spermicide products are seldom used as a separate birth control method. Usually, they are used together with mechanical contraceptives.
Condoms are the only male product among the variety of barrier contraceptives. All other things need to be inserted into the female vagina.
Condoms are considered to be one of the most popular and available means not only of barrier contraception but of male contraception, in general. Now, there are a lot of different condoms and a man can choose what suits him best. The advantages of the condoms are:
- Availability: condoms can be bought not only in drugs stores but in many supermarkets;
- Simple use: a man can quickly put on a condom right before sex and it does not require any special skills or efforts;
- Protection against pathogenic bacteria: for a man, this is the only way to protect himself against sexually transmitted infections;
- Condoms can be used with other birth control products;
- Condoms prevent the development of cervical tumors as they protect against papilloma virus;
- Condoms make sex longer and prevent premature ejaculation.
Disadvantages of male condoms:
- Low effectiveness: studies showed that the use of a condom as the only birth control method is less effective than the use of oral contraceptive pills;
- Condoms diminish the intensity of pleasant sensations during sex;
- Some people have allergy to the material of a condom or to lubrication;
- A condom can be used only during one intercourse;
The mechanism of action of female condoms is the same is of male condoms. However, female condoms are not very popular. A female condom is a contraceptive pouch 15-17 cm long and 8 cm in diameter. It is made of polyurethane. At the end of a condom there are two rings of different sizes. A ring with a smaller diameter is closed with polyurethane and it is located right in front of the uterine neck and the second ring remains at the vaginal orifice. It is very easy to use a female condom, it is inserted into the vagina like a tampon.
Female condoms have the same advantages and disadvantages as male condoms.
Diaphragms are thin domes made of latex. The diameter varies from 50 to 100 mm. There is a spring in the rim of the diaphragm forms a seal against the vaginal walls. The diaphragm covers the cervix and physically prevents sperm from entering the uterus.

- Does not have any effect on lactation;
- A woman does no need to insert a diaphragm shortly before sex because it can be inserted several hours before an intercourse.
- Low effectiveness: it should be used with spermicides only;
- It can be used only during one intercourse;
- Before using a diaphragm, it is necessary to consult a gynecologist to exclude cervical erosion. If a woman wants to use this birth control method after a child birth, she also needs to see a gynecologist first;
- Improper personal hygiene can provoke infections and inflammations of the genital organs;
- A diaphragm cannot be removed from the vagina for 5-6 hours after sex.
A cervical cap is another barrier contraception for women. It is an alternative to a diaphragm but has a smaller size. The difference is that a cap cover only the neck of the uterus.
