HC Deb 12 July 1967 vol 750 c108W
Mr. Geoffrey Lloyd

asked the Minister of Health whether, in view of indications of a statistical connection between abnormal appearance in cervical smears and the use of oral contraceptives, he will initiate more widespread research into the possibility of a causative connection.

Mr. K. Robinson

I know of the suggestion that oral contraceptives influence cervical cytological appearances; the extent and significance of this is already being studied as part of the research into the effects of oral contraceptives and I am not aware of the need for more widespread research.
