There is no guaranteed natural way to choose a baby’s sex.
A baby’s sex is determined by the sperm that fertilizes the egg.
For a girl baby, the sperm must carry an X chromosome.
If you want to try to influence the odds, speak with a fertility specialist.
Ask about preimplantation genetic testing with IVF, where allowed.
Ask about sperm sorting methods, where available and legal.
Use only medically supervised, legal options.
Avoid unproven methods that claim to guarantee a girl baby.
