I have heard in mammals that body temp can affect gender of offspring, but I don't know for sure. With my snakes, it definitely did. To get a good yield of females I incubated the female at a certain temp. But with mammals, I am not sure mothers temp makes a difference.

Mammals maintain a constant body temperature, unless they are sick, so body temperature would not affect the gender of the offspring. There is some research to suggest that diet may affect gender: http://www.biolreprod.org/content/71/4/1063.full .
In this study, climate patterns were researched with regard to affecting the gender of offspring: http://www.wildlifebiology.com/Downloads/Article/391/En/9_1_weladji.pdf.

OK now you have thrown in the monkey wrench. I will do more reading. Thx Nan

There's studies on mice regarding maternal diet, as well. High protein high saturated fats yielding 2:1 males to females, low protein low saturated fats yielding 1:2 males to females.

This is interesting as we know that with humans high protein diets are not only anabolic but also androgenic. Also with humans it has been shown that male endurance athletes who father children at the peak of their training (training volume and intensity) have lowered testosterone levels and therefore have a higher number of female offspring.

I am going to have to look more at diet and gender. Very intriguing concept!
