Female sperm tend to live longer than male sperm.
According to research, female sperm are slower but more resilient and live longer than male sperm. This information is key when considering timing for conception if a couple desires a baby girl.
- Female Sperm: Slower, fitter, lives longer.
Therefore, making love earlier in a woman's fertile window increases the chances of conceiving a baby girl because the female sperm can survive longer until ovulation.
