Combined oral contraceptives (COCs)are popular among women all over the world and have been successfully used for more than 40 years. Contraceptive pills are a very reliable means of preventing unwanted pregnancies, the likelihood of which when taking such drugs is less than 1%.
Mechanism of action of the COC
The effect of contraceptives is based onthe effect of two hormones on the body of a woman: estrogen and progestogen. Combined oral contraceptives prevent the egg from escaping from the ovary, that is, suppress ovulation, so that conception becomes impossible. Contraceptive pills thicken the cervical mucus, which makes it difficult for sperm to enter the uterine cavity. Also, oral contraceptives cause a change in the endometrial mucosa, so even if conception has occurred, a fertilized egg will not be able to attach to the wall of the uterus.

Also, combined oral contraceptives have a curative effect: the menstrual cycle becomes regular, pain disappears during menstruation, the risk of cervical cancer decreases, the skin of the face becomes clean and the hair is less greasy. Contraceptive pills are ideal for women with a regular partner: spontaneity of sexual relations is not disturbed, because the couple do not have to interrupt the process to pay attention to contraception. Oral contraceptives require self-discipline and daily intake at the same time of day. In case the woman forgot to take the pill and passed more than 12 hours, there is a risk of pregnancy.
