Little is known about the chronic toxicity of diethyl phthalate, but existing information suggests only a low toxic potential. Studies suggest that some phthalates affect male reproductive development via inhibition of androgen biosynthesis. In rats, for instance, repeated administration of DEP results in loss of germ cell populations in the testis. However, diethyl phthalate does not alter sexual differentiation in male rats.
