I am currently doing research regarding infertility and litter loss in rats, seeking common factors that contribute to infertility, resorption and runting. Most resarch that has been published has of course been conducted in relation to chemical and environmental toxins administered to rats in order to gauge risk analysis in humans.
Where can I find documented info regarding rat pregnancy itself?

Many major university pathology departments have researchers devoted to mouse and rat physiology.  I'd start looking at top medical research schools.  Their websites may contain some links to sources they are working from.
