The are reusable circular dome made of thin, soft silicone .Before sex; it is inserted into the vagina which covers the cervix so that sperm cannot get inside the womb. You need to use spermicide along with contraceptive cap as it will kill sperms.The cap must be left in place for six hours after sex. After that time, you take out the cap and wash it.
Condoms are made from thin, soft plastic called polyurethane. They are worn inside the vagina or outer layer of penis to prevent semen getting to the womb. When used correctly they help to protect against pregnancy and sexually transmitted infections
The contraceptive implant is a small flexible tube about 40mm long that’s inserted under the skin of your upper arm. It’s inserted by a trained professional, such as a doctor, and lasts for three years. The implant stops the release of an egg from the ovary by slowly releasing progestogen into your body. Progestogen also thickens the cervical mucus and thins the womb lining. This makes it harder for sperm to move through your cervix, and less likely for your womb to accept a fertilised egg.
The contraceptive patch is a sticky patch, a bit like a nicotine patch, measuring 5x5cm. It delivers hormones into your body through your skin. Which makes it more difficult for sperm to travel through the cervix; and it thins the womb lining, making it less likely that a fertilised egg will implant there
An IUD is a small T-shaped plastic and copper device that’s inserted into your womb (uterus) by a specially trained doctor or nurse.
The IUD works by stopping the sperm and egg from surviving in the womb or fallopian tubes. It may also prevent a fertilised egg from implanting in the womb.
