The endometrial lining undergoes cyclic regeneration. In contrast, endometrium that is chronically exposed to estrogens, but not to progesterone, may become hyperplastic. However, such low thickness rarely occurs, and any routine use of this parameter is regarded as not justified. Other proteins such as the HOX11 protein that is required for female fertility, is expressed in endometrial stroma cells throughout the menstrual cycle. The normal dominance of Lactobacilli in the vagina is seen as a marker for vaginal health. The arteries rupture, and the rapid blood flow dislodges the necrotic functional layer, which is lost. Their findings were seen to be unreliable due to the possibility of cross-contamination in the sampling procedures used. The first two of these regions have a characteristic appearance that is dominated by an elaborate mucosa that is thrown into numerous branched folds, surrounded by a relatively thin layer of smooth muscle. This causes cell death and the sloughing of the stratum functionalis. Simple tubular glands in the stratum functionalis open out onto the surface, and the endometrium thickens.
