There are several ways to avoid pregnancy and protect oneself from sexually transmitted infections (STIs). The most effective method is to use a reliable form of contraception, such as a condom or birth control pill.
Condoms are a barrier method of contraception that are placed over the penis or inserted into the vagina before sexual intercourse. They work by preventing sperm from entering the vagina and fertilizing an egg. Condoms are also effective at protecting against STIs, as they create a barrier that prevents the exchange of bodily fluids between partners.
Birth control pills are another effective method of contraception. These are taken orally and work by preventing ovulation, the release of an egg from the ovaries. By preventing ovulation, birth control pills make it impossible for sperm to fertilize an egg. Birth control pills are generally safe and effective, but they do not protect against STIs.
Another way to avoid pregnancy is to use a hormonal intrauterine device (IUD). An IUD is a small, T-shaped device that is inserted into the uterus by a healthcare provider. IUDs release hormones that prevent pregnancy by thickening the cervical mucus, which makes it difficult for sperm to enter the uterus. IUDs are more than 99% effective at preventing pregnancy, and they can last for several years before needing to be replaced.
In addition to using reliable forms of contraception, there are other steps that people can take to protect themselves from unwanted pregnancy and STIs. For example, it is important to communicate openly and honestly with sexual partners about sexual health and to use condoms consistently and correctly. It is also a good idea to limit the number of sexual partners and to avoid engaging in risky sexual behaviors, such as having sex without a condom or engaging in unprotected sex with multiple partners.
Overall, the best way to avoid pregnancy and protect oneself from STIs is to use a reliable form of contraception, such as condoms or birth control pills, and to practice safe sex by communicating openly with sexual partners and avoiding risky behaviors.
