The present inventions provides a method for therapeutic management of extrauterine proliferation of endometrial tissue, chronic pelvic pain and fallopian tube obstruction by short term induction treatment with an LH-RH antagonist for 4 to 12 weeks. According to another aspect of the present invention, the short term LH-RH treatment is followed by the combined or separate administration of one or more active agents selected from the group consisting of a contraceptive, preferably an oral contraceptive, a non-steroidal anti-rheumatic agent, an analgetic, an androgen other than a 17-alpha-alkyl substituted testosterone or any combinations thereof. According to a further aspect of the present invention a pharmaceutical composition comprising an LHRH antagonist and one ore more active agents selected from the group consisting of a contraceptive, preferably an oral contraceptive, a non-steroidal anti-rheumatic agent, an analgetic, an androgen other than a 17-alpha-alkyl substituted testosterone or any combinations thereof are provided.

Method for the therapeutic management of endometriosis

A copolymer derived from maleic anhydride and dicyclopentadiene, containing hydroxyl groups, having the formula: ##STR1## wherein R and R' may be the same or different, selected from the group consisting of H, C.sub.1 -C.sub.14 alkyl-isobutyronitrile, phenyl which is optionally substituted by halogen, C.sub.1 -C.sub.8 alkyl-substituted phenyl, C.sub.1 -C.sub.14 alkoxy-, C.sub.1 -C.sub.14 acyloxy- or halogen-substituted benzoyl, and n=3-10. The copolymer is useful for the sizing of paper.
