Marriages With Marital Stress Are More Likely To Have Daughters

So i read this article on TIME and i was dazzled. The research which was carried out by Duke researchers yielded a result which claims that women who reported higher levels of relationship stress, linked to an increased prevalence of later divorce, were more likely to give birth to girls.

Hamoudi, who co-anthored the research claims that “Girls may well be surviving stressful pregnancies that boys can’t survive, thus girls are more likely than boys to be born into marriages that were already strained.”

Does this mean we should make our marriages go through stress and strain if we want a girl child or more?
