RESUMEN
A case of infertility associated initially with amenorrhoea only and then with amenorrhoea and galactorrhoea following a successfully induced pregnancy is reported. In a period of eight years of continuous investigation and treatment this subject's infertility first responded to sequential clomiphene and human chorionic gonadotrophin (HCG) therapy resulting in a normal pregnancy. Subsequently she became refractory to this therapy. The availability of specific prolactin assays and a prolactin inhibitor (2-Br-α-ergocryptine, bromocriptine Sandoz) identified the aetiology of her amenorrhoea/galactorrhoea/infertility and provided a new mode of therapy. Planned conception has been achieved on three occasions, producing two normal males and a normal female child.
