@christianpoulos: Could your training intensity influence whether you have a son or daughter? Some research has found an unexpected pattern among elite athletes: a higher proportion of daughters, particularly in endurance sports. Researchers have proposed several explanations, including physiological stress, hormonal changes, and reproductive health. One popular theory involves differences in how X- and Y-bearing sperm respond to stress. The problem? Evidence that Y-bearing sperm are selectively more vulnerable is weak, and the mechanism remains unproven. We know intense training can affect fertility. Whether it meaningfully changes the sex ratio of your children is a much more interesting question. And one science hasn't definitively answered.
So even at a cellular level we are more enduring than males, but we are the weaker gender? Oh okay!

In Jamaica 🇯🇲, I always grew up hearing that strong men have daughters. To see an old saying supported by science is pretty cool.

Women also have more female babies when there is war, poverty, or if they are living in a stressful environment. Male fetuses are biologically more fragile (leading to more miscarriages) and the human body recognizes that producing a female is a safer reproductive strategy

Interesting so biology preserves the females of the species when the population experiences high stress aka when times are bad

There’s several research papers that show female infants are hartier and essentially stronger than male infants and they have a lower infant mortality rate

It's not just athletes, look at the numbers for the military and then look at the elite military like SEAL. The numbers are interesting.
