You obviously have ZERO science background and have no understanding of genetics. 
Ever wonder why there are 'miscarriages" (proper name is 'natural abortion')?
About 98% of them are because there are genetic abnormalities in the fetus. In fact, when these are developed to say 3-4 months and caught in the ER, it is common to see why the body aborted it. 
However, a number of genetic abnormalities actually are survivable. With loads of medical support (i.e. a lifetime of large medical bills), we see hydrocephalics  that make it to term and will then survive to age 5, 10, or even 30 years. Of course, they have an IQ below 50, and normally below 30, but that is a different issue. 
THis women/guy/whatever, has been told all 'her' life that she is female due to having a vagina, but, if she has a Y, she might be mentally a male. 
You can turn around and continue to denigrate me, but science is science, even if you know nothing about it.
