The invention of contraceptives has clearly revolutionized the sex life of a huge number of couples all around the world. The dosage, side effects and various other parts of general information are well known to the public. Apart from these, there is also the scientific chapter that analyzes how exactly these drugs function and the ways in which they achieve the desired outcome. In this article we are going to explicate the mechanism of Aygestin, a well known medicine that is highly effective and preferred by a large percentage of women.

birth controlAlso known as the “mini-pill”, Aygestin contains Norethisterone but no estrogen of any kind. Norethisterone, also known as Norethindrone, is a progestin that is “equipped” with steroids. It is the main ingredient of Aygestin. 

The drug prevents impregnation in three different ways:

1) It modifies the thickness of the vaginal fluids, making it very difficult for the sperm of the male partner to reach an egg and fertilize it. 

2) If the first step fails, Aygestin has another way to decrease the possibility of a pregnancy dramatically. The drug can alter the “texture” of the uterus making the fertilized egg unable to attach to its walls. 

3) It disrupts ovulation. This is the procedure during which the fertilized egg is released. It occurs during the menstrual cycle of every woman. 

The above was a brief but accurate description of the ways that Aygestin works and, for the overwhelming majority of cases, manages to prevent pregnancy. Studies have proven that it is way more effective than various other ways of birth control. However, it is less effective than pills that include both progestin and estrogen. The most crucial part of this method is to follow the instructions to the letter in order to have the highest percentage of success possibility. Complying with the doctor's guidelines is a rule that should not be broken under any circumstance for every drug.
