medications that can be harmful to female fertility


Certain medications can impact a woman's ability to conceive. This phenomenon, known as medication-induced infertility, varies in severity and duration depending on the type of drug and individual factors. Effects may be temporary or long-lasting.

Common medications affecting fertility:

1.Smarr, M. M., et al. (2023) reported that :

May affect ovarian function and follicle development
Potential to delay embryo implantation

Potential impact on tubal function

2.Casilla-Lennon, M. M., et al  (2022) reported that :

  • Certain antidepressants

5.Amabebe, E., & Anumba, D. O. C. (2020) reported that :

  • Certain antibiotics:

    • Some may interfere with hormone metabolism
    • Potential to alter vaginal and gut microbiome, affecting fertility.
Antibiotic ClassExamplesPotential Effects on FertilityNotes
TetracyclinesDoxycycline, MinocyclineMay interfere with folate metabolism
Can alter vaginal microbiome
Generally avoid during pregnancy due to effects on fetal bone development
FluoroquinolonesCiprofloxacin, LevofloxacinMay affect collagen synthesis Possible link to ovarian dysfunctionUse with caution during pregnancy; some studies suggest potential risks
AminoglycosidesGentamicin, StreptomycinPotential to affect ovarian function if used long-term
May impact mitochondrial function in eggs
                 -
Nitrofurantoin-Long-term use may interfere with ovulation in some casesGenerally considered safe for short-term use during pregnancy
Metronidazole-High doses or prolonged use might affect fertility
Can alter vaginal microbiome
Commonly used for bacterial vaginosis and other infections

6.Pennell, P. B., et al. (2022) reported that :

  • May affect hormone levels and ovulation
  • Some associated with increased risk of polycystic ovary syndrome (PCOS).
Anti-epileptic Drug ClassExamplesPotential Side Effects (Long-term use)

Calcium Channel ModulatorsEthosuximide Limited data on fertility effects
Broad Spectrum AEDsValproic Acid, Lamotrigine, LevetiracetamValproic acid: High teratogenic risk, PCOS risk
Lamotrigine: potential interaction with hormonal contraceptives

7.Korevaar, T. I., et al. (2022) reported that : 

  • Thyroid medications (if improperly dosed):

  • Both hypothyroidism and hyperthyroidism can impact fertility
  • Proper management is crucial for maintaining fertility.
Thyroid Hormone ReplacementLevothyroxine (T4)Improves fertility in hypothyroidism, Regularizes menstrual cycles,Enhances ovulation, Reduces risk of miscarriage If overdosed: symptoms of hyperthyroidism (anxiety, palpitations, weight loss), If underdosed: persistent hypothyroid symptoms
Liothyronine (T3) Similar to T4, but less commonly used,May be used in combination with T4More rapid onset of action Higher risk of overtreatment

11. Glasier, A., & Gebbie, A. (2022) reported that:
