Not sure if this is the right forum for this thread but Just wanted to share this new interessant article with you guys that states that not male embryo's but the female embryo's die during Pregnancy.
For every 100 girls, 106 boys are born. Scientist believed that this was because more male embryo's developed during conception than female embryo's, but now they found that this is probably not the case. They say that probably during conception the sex ratio is 50/50, but female embryo's have a lesser chance to survive.
The researchers based there conclusion on datasets of in total 800.000 abortions, miscarriages and amnioscentisis.
You can find the article here:
