There is a movie that I am looking for in which the plot is: a couple, the woman is a scientist/ researcher that figures out a way to separate female sperm from male sperm/ kill the female sperm. The woman is offered a new position abroad and the couple breaks up. The woman’s research gets stolen by china or another country (I think something like this but I am not sure..).
Thank you in advance:)
