Summary

The association of secondary amenorrhoea with galactorrhoea and a history of oral contraceptive treatment in a series of 230 patients has been analyzed. Ninety-six (4·17 per cent) developed their syndrome after treatment with oral contraceptives. Comparing these observations with the known usage of oral contraceptives in Australia, there is a highly significant (P<0.0l) relationship between the use of oral contraceptives and the subsequent development of amenorrhoea.

Somewhat surprisingly, although amenorrhoea-galactorrhoea is more commonly associated with a history of oral contraceptives than any other factor, such history had no effect upon the proportion of secondary amenorrhoea patients with concurrent galactorrhoea.
