Human decidua-associated protein 200 levels in uterine fluid at hysteroscopy.

Hysterosocpic intrauterine findings and levels of human decidua-associated protein 200 (hDP 200) in the uterine fluid were recorded in 116 women investigated for infertility or recurrent abortions. The levels of hDP 200 were significantly higher in the presence of submucous myomas or endometrial polyps, and lower in the presence of intrauterine adhesions in comparison to those in normal uterine cavities. hDP 200, an immunoglobin secreted by the endometrium, may be involved in implantation and placentation and its level in the uterine cavity is influenced by the presence of intrauterine pathology.
