Birth control methods are classified into four major groups.
- Hormonal methods
- Barrier methods
- Chemical methods and
- Natural methods.
Hormonal birth control methods
Works in one or more ways: by preventing females from ovulating (releasing eggs), by blocking the sperm from entering the cervix and by preventing the embryo from attaching to the lining of the cervix.
Works by blocking the sperm from reaching the egg by using; condoms (male and female), diaphragm, cervical cap, and contraceptive sponge.
Chemical birth control methods
Chemical birth controls create a reaction in the body that reduces the chance of fertilization (sperm connecting with the egg).
Natural birth control methods
Natural birth control is the methods like safe period calculation along with the withdrawal method when a female is most likely to get pregnant without any side effects.
How do birth control methods work?
Each of these birth control methods works in different ways and most of the artificial birth control methods are associated with mild or serious health risks and side effects. The failure rate of birth control methods varies from method to method. Hormone pills, patches, shots, implants, or devices keep the eggs from being released. Gels, foam, vaginal sponge, and spermicides kill the sperm. Male and female condoms, diaphragm, and cervical caps block sperm from reaching the cervix. Some IUDs or hormones change the uterus lining structure so that an embryo can’t attach. Male and female sterilization block the passage of eggs through a female’s fallopian tubes or sperm from a male’s vas deferens.
