Everything you need to know about contraceptive methods.

While various techniques exist to prevent unwanted pregnancy, the combined estrogen-progestin pill remains one of the most common methods. Indeed, about 4 in 10 women use this form of contraception in France.

The contraceptive activity of these pills is attributable to two molecules: synthetic estrogen and progestin. This type of pill should be taken every day at the same time for 21 days, followed by a 7-day break. It is during this week that menstruation occurs, or rather withdrawal bleeding, which is less heavy than "real periods". Indeed, here, the bleeding is due to the sudden drop in hormones when the pill intake is stopped. If you take the pill correctly, you will be protected throughout the month, even during the break week! There are four safeguards that ensure its effectiveness:

1. The progestin thickens the cervical mucus, which hinders the passage of sperm.

2. Estrogens prevent the growth of the follicle.

3. The two types of hormones inhibit ovulation.

4. The progestin makes the uterine lining unsuitable for the implantation of a fertilized egg.

There are several generations of contraceptive pills, with the second-generation pills presenting the lowest risk of venous thrombosis, thus they are the preferred choice.
