    Women who previously used oral contraceptives, often called "the pill," may take longer to conceive. This study suggests a 15-month timeframe may be a better definition of infertility for these individuals.

    Area of Science:

    • Reproductive Endocrinology
    • Human Reproduction
    • Contraception Research

    Background:

    • Understanding post-contraceptive conception intervals is crucial for reproductive health.
    • Previous oral contraceptive use may influence time to conception.
    • Current definitions of infertility may not account for specific contraceptive histories.

    Purpose of the Study:

    • To investigate the time interval from cessation of contraception to conception in women with a history of oral contraceptive use versus other methods.
    • To determine if a longer period of attempting conception is needed for previous oral contraceptive users to be considered infertile.

    Main Methods:

    • Analysis of interview data from 3,214 married women with planned pregnancies and singleton deliveries.
    • Exclusion of women with fertility treatment history and those conceiving within two weeks of stopping contraception.

  • Comparison of conception rates between former oral contraceptive users and users of other contraceptive methods using logistic regression.

    • Main Results:

    • 24.8% of former oral contraceptive users required 13 months or longer to conceive, compared to 10.6% of users of other methods.
    • Oral contraceptive users exhibited lower monthly conception rates in the initial 3-10 months post-cessation.
    • These findings remained significant after controlling for confounding variables.

    Conclusions:

    • Previous oral contraceptive use is associated with a prolonged time to conception.
    • A 15-month interval of unsuccessful conception attempts may be a more appropriate definition of infertility for prior oral contraceptive users.
    • This research suggests reconsidering the standard 12-month infertility definition for this demographic.
