Diaphragm use, particularly for over a year or within one year of conception attempts, was linked to abnormal postcoital test (PCT) results and infertility. Other barrier methods and contraceptives showed no increased risk.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Research
  • Contraceptive Technology

Background:

  • Cervical mucus abnormalities can impact female fertility.
  • The postcoital test (PCT) is a diagnostic tool for evaluating cervical mucus function.
  • Understanding risk factors for infertility is crucial for reproductive health.

Purpose of the Study:

  • To investigate the association between contraceptive methods and abnormal postcoital test (PCT) results in infertile women.
  • To identify specific contraceptive practices that may increase the risk of infertility.
  • To compare the reproductive histories of infertile women with abnormal PCT results to fertile controls.

Main Methods:

  • A population-based case-control study design was employed.

  • Reproductive, contraceptive, medical, and sexual histories were collected from infertile women with abnormal PCT results and fertile controls.
  • Statistical analysis, including relative risk (RR) and 95% confidence intervals (CI), was used to assess associations.

    • Main Results:

    • Infertile women with abnormal PCT results showed a higher prevalence of previous diaphragm use compared to fertile controls (RR = 3.5).
    • Extended diaphragm use (over one year) or use within one year of attempting conception significantly increased the risk of abnormal PCT results (RR = 7.3 and RR = 5.5, respectively).
    • No increased risk of abnormal PCT results was associated with other barrier methods, oral contraceptives, or intrauterine devices.

    Conclusions:

    • Diaphragm use is associated with an increased risk of abnormal postcoital test results, suggesting a potential link to infertility.
    • The risk appears to be dose-dependent, with longer duration of use and recent use before conception attempts posing the highest risk.
    • Further research is warranted to elucidate the mechanisms behind this association and guide clinical recommendations regarding diaphragm use in women seeking conception.
