Anatomical and functional changes induced by oral contraception.

Y Lefebvre

    Canadian Medical Association Journal
    |March 28, 1970
    PubMed
    Summary

    Hormonal contraceptives may cause ovarian changes and temporary menstrual irregularities like amenorrhea after discontinuation. A 6-8 month gap post-contraception is advised before pregnancy attempts.

    Area of Science:

    • Gynecology
    • Endocrinology
    • Reproductive Health

    Background:

    • Hormonal contraceptives are widely used for family planning.
    • Understanding their long-term effects on reproductive organs is crucial.

    Purpose of the Study:

    • To investigate the effects of hormonal contraceptives on the cervix and ovaries.
    • To assess the impact on menstrual cycles and fertility post-cessation.

    Main Methods:

    • Histopathological examination of cervical and ovarian tissues.
    • Analysis of menstrual cycle patterns and time to conception after stopping contraceptives.

    Main Results:

    • Hormonal contraceptives did not directly affect cervical carcinoma or dysplasia but caused endocervical glandular hyperplasia.
    • Long-term progestin use led to inactive ovaries with thickened tunica albuginea and reduced follicle growth.
    • Post-contraception, irregular cycles and secondary amenorrhea were observed, likely due to hypothalamic or ovarian factors.
    • Time to conception averaged 5.8-6.5 months, with no increased abortion rates but a higher polyploid tendency and chromosome breaks in abortuses.

    Conclusions:

    • Hormonal contraceptives induce specific histological changes in the endocervix and ovaries.
    • Reproductive function may be temporarily altered post-cessation, necessitating a waiting period before pregnancy.
    • Further research is needed to confirm findings on abortus chromosomal abnormalities.
