Well, they're not actually "missing". They're dead -- killed for being born without penises.
And this is the result:
Tens of thousands of girls disappear in India every year. They are sold into prostitution, domestic slavery and, increasingly, like Rukhsana, into marriage in the northern states of India where the sex ratio between men and women has been skewed by the illegal - but widespread - practice of aborting girl foetuses.
An estimated 25-50 million "missing" women in India. As well as infanticide and foeticide, childhood neglect is a problem and many women die early in adulthood.
