Haven't looked at it in detail, but this links to several studies that observe that oral contraceptive use is associated with later age at last menstrual period. This is consistent with the theory that menopause is associated with oocyte depletion and the contraceptive pill working by preventing ovulation.
Trouble is that it's hard to know to what extent it's the contraceptive pill that's making the difference, and to what extent it's other factors correlated with the pill.
