According to sources from the Ministry of health and Social policy, the morning-after pill after emergency contraceptive known will be sold without prescription in pharmacies and anyone, including minors. The debate is open, but we clarify the mechanism of action of this drug

The to tell the truth, there are few substances having so many effects at the same time as Levonorgestrel is a contraceptive and in turn prevents the embryo nest. As you know, this medication must be taken within 72 hours, the limit of nesting. The clinic has shown us that, through mechanisms ovocidas and spermicides prevents fertilisation of the first, i.e., in this regard would act as a common contraceptive. in turn can prevent the nesting (or implementation) of the embryo, what is this? Once fertilized the egg, the genetic material of the sperm and the egg meets each on their own, in a few pronucleos. They remain merged 24 hours approximately, during which degenerate sperm mitochondria (why we alike them through a maternal). Once formed the Zygote, this must be implanted in the womb of women, which will undergo a series of changes (including genetic) and are feed ”. Approximately an 60-80% of the zygotes do not anidarán in a spontaneous and natural way.

What does the Levonorgestrel to avoid nesting?

* becomes less acid pH of the uterus (therefore more alkaline)

* affects the movement of the fallopian tubes

Because of this, the Zygote does not implant and is expelled through menstruation. After 72 hours the effectiveness of this pill is almost non-existent, since it has been demonstrated that once the embryo is implanted, this medicine lacks effectiveness; that is why is not an abortifacient.
