Wouldn't have worked otherwise (at the current state of know-how), since males and females silence different genes in their germ cells in the process called genomic imprinting. Experiments in fusing two female haploid nuclei have failed for this reason - key constructional mechanisms have been turned off.

Can't live with 'em, can't live without 'em (for now).
