 * sounds of a struggle with cat howls and dog barks ending in both crying out in moans of ecstacy*

Okay, if mamono get spirit energy from male reproductive fluid, and get pregnant from it, how do they only get female offspring? I mean, the female drops an egg with an X chromosome and male sperm cells come in either X or Y, how do only the X sperm cells survive? Wouldn't there be even the slimmest chance of a Y chromosomal sperm fertilizing the egg cell to make a male fetus? Or do incubi only produce X chromosome sperm instead of X and Y?
