I have just read this article and it may not be of direct help to
many, but at least it may point to some future directions of where
research may take us.

One in six couples worldwide faces infertility problems and nobody has been able to find out the exact reason why. 

But a team of Rutgers genetic researchers have discovered the mystery behind fertility: two genes, namely egg-1 and egg-2, necessary for this process. 

The proteins encoded by these genes are similar to low density lipoprotein (LDL) receptors, known from cholesterol and fat metabolism but never before specifically implicated in fertilization. 

Researchers noticed that in the absence of these two genes, the vital process of fertilization halted.
