Why? Because when a person is pregnant, of course they have to go through several medical tests, but at week 18 we know that around that time women undergo an ultrasound scan. That is an important part of medical testing to ensure the wellbeing of the fetus, but at that time very easily the gender of the fetus can also be found out and that is actually a normal process in the whole medical care that is provided to a pregnant women. I fully support that; yes, women should get all possible tests they should have to ensure the wellbeing of their fetus, but that is something that is very easy to do at 20 weeks. So by reducing the time from 20 weeks to 12 weeks, it will not be that easy. I'm not saying that the gender of the fetus cannot be detected before 12 weeks, but what I'm saying is that it is difficult and by 20 weeks it becomes really easy.
