A πregular semigroup S is called strictly πregular

if the set of regular elements of S is an ideal of S and is a completely regular subsemigroup of S. We use the notion of a fuzzy congruence relation on semigroups to study some properties of fuzzy congruences on πregular semigroups. Some properties and characterizations of fuzzy congruences on strictly πregular semigroups are given

and the group congruence on such semigroups is obtained. Finally

sufficient and necessary conditions for a fuzzy congruence on a strictly πregular semigroup to be a fuzzy group congruence are proved.
