Have sex during the fertile window if you are trying to conceive
Use a sperm donor or donor embryo if you want a higher chance of a female child through medical selection
Consider IVF with preimplantation genetic testing where legal and available
Consult a fertility specialist about sex selection laws and options in your area
Understand that natural methods do not reliably determine a baby’s sex
If you are asking about gender identity rather than sex at birth, support the child’s identity and expression
