Several studies have indicted angiogenesis in the pathogenesis of endometriosis, and the cell factor is associated with angiogenic activity. Patients contending with endometriosis-related infertility appear to produce even higher levels of the factor, which is known as macrophage migration inhibitory factor (MIF).
Medical researchers in Canada have studied MIF levels in the peritoneal fluid of females with endometriosis, other women with endometriosis-associated fertility, and healthy women without endometriosis.
"The study demonstrated the presence of MIF in the peritoneal fluid and a 238% increase of MIF levels in women with endometriosis as compared with healthy women," reported R. Kats and colleagues of the Center for Research at the Hospital of St. Francis Espinay in Quebec City, Canada.
MIF levels were significantly higher in infertile women with endometriosis than in the other two groups of women (Marked elevation of macrophage migration inhibitory factor in the peritoneal fluid of women with endometriosis. Fertility and ...
