Birth defects & Infertility are not genetic and can be eliminated with proper nutrition!
Both the Man and Woman need to have properly nutrified bodies to conceive a child much more easily. You both need to have the correct raw materials to conceive. There is no need for expensive infertility drugs and extremely expensive artificial fertilization processes done, often with disappointing results requiring multiple attempts. Besides making babies the natural and traditional way is much more intimate and fun.
Prior to conception proper nutrients must be taken and continued during pregnancy so that while the baby is developing, in the first three months, all the raw material are there to create a perfectly developed baby.
If mothers are supplemented properly prior to and during pregnancy their developing babies will not have any birth defects because they are ALL PREVENTABLE.
