title: Plasma alpha-feto protein levels and its relation to duration of oral contraceptive use.
abstract: Plasma alpha-feto protein (AFP) levels were measured by radioimmunoassay in 73 women using oral contraceptive pills for varying durations of time. The levels were significantly higher at 6 months of pill use and tended to return to normal after 12 months. In none of the women was plasma AFP higher than 25 ng/ml which is considered to be indicative of liver damage.
