[Nonsurgical treatment of unruptured ectopic pregnancy with methotrexate (MTX) (introductory remarks)].

Seven patients with an unruptured tubal pregnancy were treated with a single i.m. injection of methotrexate (1 mg per Kg) and monitored with beta hCG titer and ultrasound examination. Two of them required two doses for declining beta hCG titer. Among four infertile patients HSG done on two subsequently demonstrated tubal patency on the involved side in one patient.
