At the recent meeting of the American Gynecological Society I presented a lengthy contribution on the "Regeneration of the Uterine Mucosa After Delivery, with Especial Reference to the Placental Site." At that time, I reviewed the literature, demonstrated forty-eight lantern slides illustrating my own observations, and drew the following conclusions:
The mucosa of the cervical canal is restored by the end of the first week.
Outside of the placental site the endometrium becomes regenerated during the course of the third week.
The placental site persists for from six to seven weeks, and its disappearance is effected by a process of exfoliation which in great part results from undermining by endometrial tissue.
My object in this paper is to describe briefly the changes occurring at the placental site, and those who may be interested in what occurs outside of it, or in the literature on the subject, are referred to the
WILLIAMS JW. DISAPPEARANCE OF THE PLACENTAL SITE DURING THE PUERPERIUM. JAMA. 1931;97(8):523–529. doi:10.1001/jama.1931.02730080015006
