polyunsaturated fat begins to look worse and worse for testosterone production here they have another study here the beneficial effect of monounsaturated fat on testosterone is supported by another study which replaced 25 grams a day of butter with either olive oil or argan oil and found total testosterone increased by 17.4 percent and 19.9 percent that one's interesting to me because they're taking out an animal fat and increasing olive oil or argan oil but in general i think that high pufa versus monounsaturated fat or saturated fat diets resulted in decreased testosterone production via increased testicular oxidative stress decreased steroidogenic enzymes and decreased testosterone testicular free cholesterol available for steroidogenesis
polyunsaturated fat to saturated fat ratio as the amount of polyunsaturated fat increases right you get a bigger number here serum testosterone goes down
