Having too many stresses when you are pregnant would result in decreasing the time of being pregnant and getting fewer males.  To find out the pre-term birth, they did a research on 100 female pregnancies and they have found that about 4% would have pre-term birth in the first two months. To research on males are less than female when pregnancies under stress, they gather the statistics in the third month and they found boys are less than girls.
