Hysterofiberscope equipped with a laser blood-flowmeter. The endometrium is illuminated by linearly polarized laser light through the optical fiber probe; scattered light is detected simultaneously by the probe.

3. FIGURE 2
Immunohistochemical localization of vascular endothelial growth factor (VEGF) in human secretory endometrium. VEGF immunoreactivity, shown as red areas, is confined to glandular epithelial cells, with little detectable immunofluorescence in stromal cells. Immunoreactivity is stronger in (A) a woman who became pregnant than (B) one who did not. Nuclei are shown in green. Scale bar = 10μm.

Time-averaged mean of endometrial tissue blow flow (mETBF) in the fundus (F) and anterior (A), posterior (P), right-lateral (R), and left-lateral (L) walls of the endometrium in normal and abnormal uteri. ∗ = P<.0001 vs. A/P/R/L group (ANOVA and Fisher’s PLSD).
