Pathology and treatment of diseases of women . uringthe flow, reaching soon afterward its lowest point and gradually ascend-ing again to its height. A gradually increasing hyperemia of the entiregenital organs, the premenstrual congestion, develops during the latterpart of the ascent. The mucous membrane of the uterus swells, the ves- DEVELOPMENT OF THE FEMALE GENITALIA 15 sels become filled to bursting, and an interstitial edema occurs. The sin-gle cell of the stroma also increases in size (formation of a pseudo-decidua). A voluminous extravasation of red blood-corpuscles, partlyby diapedesis, partly by rhexis, takes place at the height of this hyper-emia; these red blood-cells collect especially underneath the cortical epi-thelium as small extravasations of blood (subepithelial hematomata) (seeFig. 9). The epithelial layer thus detached ruptures in isolated places, andtransmits the blood to the surface drop by drop. Hare it is mixed withthe uterine secretion which forms abundantly during the congestion, and m fP- GE •.vl •J?. Fig. 10.—Surface and Cortical Layer of a Normal Ovary.

As aresult of this admixture with the mucous secretion the menstrual blooddoes not clot. It forms light red stains with a yellowish border on theclothing. The epithelial layer which becomes detached during the ex-travasation of the drops of blood does not perish, but reattaches itself toa very great extent, and the few shed cells are quickly replaced. Arapid decrease in size of the mucous membrane occurs during the a short intermission a slow growth sets in again until the occur-rence of the next premenstrual congestion. This process of menstruation, however, is not a self-dependent one. 16 DISEASES OF WOMEN It is dependent
