Not comfortable thinking about the Nazis and reproductive science well let's move on to safer ground. In another corner of European Society of Human Reproduction and Embryology conference Dr David Gardner, Scientific Director of the Colorado Center for Reproductive Medicine, Englewood, USA reported that a high protein diet may interfer with a womans ability to get pregnant. Speaking of mice he said

Analysis of foetal development on the fifteenth day of gestation showed that foetuses from the high protein group were a third of a day behind the control group in their development, and one foetus had a neural tube defect.

He hypothesises that this is because a high protein diet results in an increase of the level of ammonium in the system, a chemical that is known to interfer with embryonic development.

He suggests that if you are trying to conceive then you forget the prime rib steak and keep your protein intake to less than 20% of your total energy intake. By way of comparison, the average American derrives 14% of their energy from protein.
