ABSTRACT:
Methods of screening for endometriosis comprise obtaining a sample of endometrium selected from menstrual cycle day 20 to 24, identifying the endometrial sample as nulliparous, contacting the endometrium with a monoclonal antibody for .beta..sub.3 integrin, assaying for .beta..sub.3 integrin and correlating the absence of .beta..sub.3 integrin with endometriosis, wherein the endometrium is identified as mild/minimum endometriosis. A method of using monoclonal antibodies to screen for endometriosis is also within the scope of the invention. Methods for detecting receptivity of mammalian endometrium to embryo implantation comprising obtaining a sample of the endometrium, contacting the endometrium with a monoclonal antibody for .beta..sub.3 and detecting .beta..sub.3 in the endometrium. The invention also provides for methods of diagnosing infertility in a mammal and methods of detecting the window of embryo implantation in endometrium. Methods of in vitro fertilization, methods of preventing embryo implantation and a method of monitoring endometrial maturation are also within the scope of the present invention. Diagnostic kits useful in the practice of the methods of the invention are also provided.
