How do contraceptive pills work?

The

hormonal contraceptive pill was first launched in the United States at the age of 60 and had a deep impact on the world. This allowed women to engage in sexual activity at any time during their menstrual cycle without fear of pregnancy, and basically worked by forcing the body to think that it was already pregnant with timed estrogen doses. In addition to estrogen, progesterone pills, other female hormones that affect the reproductive system. When purchased according to the instructions, most pills are more than 90% effective.

The beginnings of the pill can be found in experiments on rabbits at the age of 30, when scientists found that high doses of progesterone prevented ovulation, which means that no eggs would be released to be fertilized. In the 40s of the 20th century, scientists successfully synthesized both estrogen and progesterone and opened the way to a pill of contraception, which was developed and tested in the 1950s. In 1960 approved food administration and medicineUsing a pill for American women and human sexuality and family planning have not been the same since then.

The hormones used are combined to prevent the body from released eggs. If the eggs are released, progesterone makes traveling on the fallopian tube and also changes the uterine lining to prevent implantation in the unlikely case of fertilization. In addition, progesterone thickens cervical mucus, so the sperm has difficulty getting into the uterus. The combination of estrogen and progesterone makes pregnancy a challenge, even if it can happen.

Condoms should always be used during sexual activity to ensure STD protection and special pregnancy insurance. Proper combined use of the condom and pill will significantly reduce the risk of pregnancy and prevent infections by potentially incurable STD.
