THE CONTRACEPTIVE

TABLET

The contraceptive pill is one of the most important Mexican contributions because it has a social impact at the munici- pal level.

The contraceptive pill is a pill with hormones that alters the body's functioning to prevent pregnancy. Hormones are chemical substances that control the functioning of the body's organs. In this case, the hormones in the pill control the ovaries of the uterus.

What is it?

How it works?

This works thanks to Norethisterone because it interrupts the reproductive machinery of women. When a woman takes one of these pills she tells her brain that the body no longer needs hormones for the ovaries to generate ovules, breaking the reproductive cycle of each month.

The level of effectiveness is 99% and nowadays the side effects practically do not occur, which has led the World Health Organization to argue that oral contraceptives can be taken without risk.
