Postovulatory effects of Levonorgestrel in emergency contraception

Hello to all, today I going to talk about the speech of the Dr. Valenzuela over the Postovulatory effects of Levonorgestrel in emergency contraception.
The presentation was very interesting for me because the Dr. Valenzuela talk about topics nearly to our career.
The Levonorgestrel is a type of Progesterone, used in the monophasic and triphasic formulation of combined oral contraceptives pills in low doses. The other use and the most important, is in the Emergency contraceptives pills (ECPs) both in a combined Yuzpe regimen which includes estrogen, and as a Levonorgestrel only method. And the final use and less important is in the intrauterine contraceptive device with progestogen.
Levonorgestrel in form of ECPs is used 24 to 120 hours after unprotected sex, with a maximum effectiveness in the first three days.
I am agree with the use of Levonorgestrel as Emergency contraceptive pills but in only one instance and it is when a woman is violated and she didn’t want to get pregnant, because first would be an unwanted pregnancy and second she didn’t the possibility of use an contraceptive method. For this to my mind the pill shouldn’t be give to the women that haven’t was violated because they have the option of use an contraceptive method or demand to their couple that they use a preservative.
Dr. Valenzuela doesn’t consider that the Levonorgestrel is abortive, and I agree with him, because the life begin when the Nervous System begin to develop, and the Levonorgestrel exerts its effect before than it does occur.
