Sex determination techniques for insemination
Active prejudice towards undesirable sperm
A clinic in Hong Kong charges £2,500 for separating male and female sperm and insemination. The process it uses, devised 20 years ago, is considered 75-80% reliable for selecting boys and 70% for girls.
In gender selection, it is women who always suffer the discrimination. The operation of such a clinic keeps that kind of thing going.
