Ttc boy 2023

we are 3 sisters and we all have girls

I have 3 girls
2nd sister have 4 girls
3rd sister have 2 girls

do some people genetically give birth to only girls?

No. In fact, I often see women from all-girl familes on here who have all or mostly boys, or most often of all, all-girl families where there are 2 with all boys and one with all girls or vice versa.

You guys were raised with similar diets and lifestyles, some of that carries over into adulthood in terms of habits/preferences that you have, and those things sway gender.

There are not boy genes and girl genes, and this has been proven true by scientists and mathematicians. The reason is that it's impossible. If there were such a gene that could make one family have more girls, it would quickly spread out of control as more and more people were born with it. If it existed, there would be tribes, villages, ethnic groups, or nations that have skewed gender ratios, but it's always 50-50 wherever you go.

Based on your family it is easy to assume that. But I think not all pregnancies are alike. Must be just coincidence with your sisters. How are you doing with your sway? In my case I am having egg donation, so we can have the gender predicted in PGD test.

I don't think it's genetics. But in your family I can understand why you think it would. How are you in swaying for a boy?
