This question is a bit misleading, as only females have eggs, and only males have sperm. The question may be trying to ask about sperm containing the X chromosome, which determines female sex, and whether they survive longer than sperm containing the Y chromosome, which determines male sex.
In this case, the answer is yes, sperm containing the X chromosome (female sperm) tend to survive longer in the acidic conditions of the vaginal canal. This is because they are generally considered more robust and resilient than Y sperm, which are faster but die off quicker. This is why timing intercourse closer to ovulation can increase the chances of conceiving a boy, as the Y sperm will have less time to die off and can reach the egg first.
It's important to note that:
- While this is a common belief, there is no guaranteed way to select the sex of your baby.
- There are many other factors that influence sperm survival and fertilization, including sperm count, motility, and the health of both partners.
