Are there any side effects if genomic imprinting no longer exists?

I'm trying to make a world that human sex ratio is 2:8 (male:female). Most of the females are homosexual, and male is not necessary for reproduction. I thought it was easy at first, just say that there is technology for combining two eggs... but I discover that there is a phenomenon called Genomic imprinting.

Due to genomic imprinting, some genes are deactivated in eggs, and some genes are deactivated in sperms. So no offspring can be produced by combining two eggs.

If we remove imprint of genes related to growth, then it is possible to produce offspring. But the probability is still very low. See this experiment on a mouse.

I want to make "there is no genomic imprinting in human in this world" as axiom. But I don't know whether genomic imprinting plays important role in some process in human. Are there any side effects if we don't have genomic imprinting? Such as intellectual and developmental disability... (I know there may be some sociological consequences, I want to focus on biology first.)

P.S. Science is like that.... If you change something for some purpose, there is always side effects, especially physics, sometimes your idea cannot be used because of the side effects.
