New research may help some women's struggles to have a child. Researchers have uncovered clues that may help take some of the guesswork out of fertility treatments, according to WLWT HealthTeam 5 reporter Lisa Cooney.
Severe endometriosis is a known cause of infertility.
The condition happens when the endometrial lining grows outside the uterus. Cooney said that the link between infertility and milder cases of endometriosis isn't so cut and dry. As many as half of women with endometriosis will become pregnant without any treatment. Scientists have identified two proteins , beta-3 and lif, that are missing in some women with endometriosis. Researchers believe that the lack of those two proteins cause infertility by interfering with the embryos ability to attach to the uterus.
