The contraceptive cap is a circular dome made of thin soft silicone and is inserted into the vagina before sexual activity occurs. It prevents sperms from reaching the uterus. Spermicide is used along with it to kill the sperm. The cap is left in place for six hours after sex and then taken out and washed. The caps come in different sizes and a person needs to get fitted for a correct size by a doctor or trained health specialist. They are also reusable. However it is important to note that a cap only provides limited protection against STIs. It is also more effective for women who have never given birth.
It is a tablet that is swallowed once a day and it contains estrogen and progestin which are female hormones. It prevents pregnancy by mainly preventing ovulation (the release of an egg) from occurring. It also affects the uterine lining and cervical mucous making the chances of a sperm fertilizing the egg very rare.
According to Merriam Webster’s dictionary a condom is a sheath commonly of rubber worn on over the penis so as to prevent conception or venereal infection during coitus. It is also defined as a device that is inserted into the vagina before coitus and that resembles in form and function the condom use by males. Condoms protect against both STIs and pregnancy.
