@midwife_jenny: The biological sex of a baby is determined by the sperm from the father at fertilization. The mother’s egg always carries an X chromosome, while the father’s sperm carries either an X or Y chromosome. X sperm + X egg = XX → typically female Y sperm + X egg = XY → typically male Therefore, it is the sperm that determines whether the baby is typically XX or XY. This happens naturally and is not something either parent can consciously control. Scrubs from @OBREMPONG CUSTOMIZED SCRUBS #fertility #gender #parentsoftiktok #marriedlife #healtheducation
