"My child happens to be male."
Congratulations!  He's hit the jackpot. The cards are very much still stacked in his favour just because he is male and, I presume, white - double jackpot!!
There is no evidence of sexism against males.  That you believe there is simply because more women are being selected for important jobs, is your problem.  Why on earth would you presume that just because there are more women, that 1. they must surely be unqualified and 2. some more deserving male must surely have been passed over because of sexism?

Wake up!
