Undetected endometriosis interferes with the ability of a fertilized egg to implant. Endometriosis can block successful implantation regardless of how a woman gets pregnant, through normal sexual intercourse or IVF. While many patients hear about endometriosis in women who have experienced pelvic pain, painful intercourse or heavy bleeding during menses, milder forms without symptoms (Silent endometriosis) can be present without experiencing any physical symptoms. These milder forms of endometriosis are often undetectable and cannot always be visualized through ultrasound or laparoscopy. This is the power and benefit to patients by having the ReceptivaDx test performed.
