Contraception Pill

All of us know that the contraception pill is a controversial topic in the field of health and in public opinion. In the letter to editor entitled "Postovulatory effects of levonorgestrel in emergency contraception (LNG EC), the Dr. Carlos Valenzuela think that there are evidence of post ovulatory action of levonorgestrel. Also The data show definitive postovulatory effects of LNG EC with a probability distribution of pregnaniesw issued from daily intercourses within the fertile period of the mestrual cycle. The doctor Croxato thinks that the doctor Carlos Valenzuela is wrong.He thinks that the studies that used Dr valenzuela don't have built-in mechanism of action studies. Which means that the studies don't have an appropiate aspecific experimental design. He object to contrasting the effectiveness of LNG for interfering with the ovulatory process. Also he discusses that the data was wrong. The expected pregnancy rate in the calculations has no relevance to the clinically observed pregnancies reported in efficacy studies reported. This debate isn't finish. Follow in the future and I think that will not stop. The goverment decided give the pill at the population. I think that the values of people are losing in the freedom that the society gives to the people. I don't know if the contraception pill have postovulatory effects, I think the problem isn't that. I hope that some day somepeople give us the answer if is or isn't postovulatory pill. This discusse is interesting and I like to read infomation about it. I hope read to a lot of Doctor valenzuela in the future.
