Sperm Separation Method May Allow Gender Selection in IVF

August 14, 2019

(The Guardian) – A new sperm separation technique may one day allow prospective parents undergoing IVF to choose whether they have a boy or a girl before fertilisation takes place, researchers say. Scientists in Japan have reported a new method which allows them to separate mouse sperm carrying an X chromosome from those carrying a Y chromosome, meaning that sperm can be selected based on whether they will result in female (XX) or male (XY) offspring when used to fertilise an egg.
