Reduced nitric oxide synthase and cyclo-oxygenase activity in the uterus of non-obese diabetic mice
A functional interaction between progesterone, Th2 cytokines and a suitable balance between nitric oxide and prostaglandins in the uterus is considered to have a major role in the success of embryo implantation and pregnancy. Non-obese diabetic (NOD) mice offer a suitable model to study the modulato...
