What are the measures to prevent pregnancy?

Measures to prevent pregnancy include using condoms, birth control pills, and wearing contraceptive rings.

1. Condoms: Condoms are made of polyurethane and latex materials, have strong toughness and thermal conductivity, and are a more practical, safer and more convenient method of contraception. They can prevent semen from entering the female vagina, thereby achieving a contraceptive effect. They can also avoid the symptoms of viral or bacterial infection, but cannot achieve 100% contraceptive effect.

2. Contraceptive pills: Contraceptive pills are a commonly used drug for women. They are made of estrogen and progesterone. They need to be taken orally within 24 hours after having sex. They can prevent the combination of sperm and egg, thereby achieving a contraceptive effect. However, it is not recommended to take contraceptive pills for a long time, because long-term use of contraceptive pills may cause a series of side effects in the body, and in severe cases may even lead to infertility.

3. Contraceptive ring: The contraceptive ring can play a very good contraceptive effect, generally can achieve 100% contraception, and the contraceptive ring can be used for a relatively long time, is relatively safe, and will not cause inflammation of the vagina and cervix. You need to go to the obstetrics and gynecology department of a regular hospital and let the attending doctor use special instruments to install the contraceptive ring in the cervix to play a contraceptive role.
