по статистике "Like most sexual species, the sex ratio in humans is approximately 1:1. The sex ratio at birth is commonly thought to be 107 boys to 100 girls,[2] although this value is subject to debate in the scientific community. The sex ratio for the entire world population is 101 males to 100 females.[3] Depending upon which definition is used, between 0.1% and 1.7% of live births are intersex."
