"In their original paper, Trivers and Willard were not yet aware of the biochemical mechanism for the occurrence of biased sex ratios. Eventually, however, Melissa Larson et al. (2001)[3] proposed that a high level of circulating glucose in the mother's bloodstream may favor the survival of male blastocysts. This conclusion is based on the observed male-skewed survival rates (to expanded blastocyst stages) when bovine blastocysts were exposed to heightened levels of glucose. As blood glucose levels are highly correlated with access to high-quality food,[4] blood glucose level may serve as a proxy for "maternal condition"
Sexual dimorphism among bovine embryos in their ability to make the transition to expanded blastocyst and in the expression of the signaling molecule IFN-τ
"Sexual dimorphism among bovine embryos in their ability to make the transition to expanded blastocyst and in the expression of the signaling molecule IFN-τ"
"However, in either tissue culture medium 199, which contains 5.5 mM d-glucose, or in synthetic oviductal fluid, in the presence but not in the absence of added glucose, significantly fewer female than male embryos were able to progress from the morula/early blastocyst stage to more advanced stages of development. It is possible that the differences between male and female embryos both in their production of IFN-τ and in their ability to progress in development in glucose-rich media are manifestations of phenomena that occur in vivo and provide plasticity in embryo selection during early pregnancy."
Reminds me of this:
RAY PEAT: Obstetricians, as recently as old people that I knew, old doctors in the 1970’s were still aware of the fact that their so-called diabetic mothers very often had extremely precocious babies. I talked to one woman who was told to go on a reducing diet because of her previous pregnancies. She had had very high blood sugar, and I asked her how that baby had turned out. She said, "Oh, he taught himself to read when he was two years old. When he was four he was already wearing adult hat sizes”, which is basically an extension of what Zamenhof demonstrated with chicken embryo development. Sugar is the limiting factor, usually, in brain development. In the 1970’s, doctors were looking for new diseases to treat, and diabetes was extended to include the very completely new concept of gestational diabetes. And where a 130 blood sugar had been considered very healthy for a pregnant woman, they now wanted to restrain the level of blood sugar during pregnancy. And they started calling it a disease. “gestational diabetes”, that really was just a healthy pregnancy in most cases.
So the secret to having prodigal sons, and lots of them, is to make sure your wife has plenty of sugar?
