Does endometrium nourish the ovum

No, the endometrium does not nourish the ovum directly. Instead, the endometrium is the lining of the uterus that thickens in preparation for a potential implantation of a fertilized egg. If fertilization occurs, the developing embryo receives nutrients from the endometrial tissue once it implants. If there is no implantation, the endometrium sheds during menstruation.
