Thyroid hormones play a vital role in regulating reproductive health. When the thyroid is underactive (hypothyroidism) or overactive (hyperthyroidism), it can disrupt the delicate hormonal balance needed for ovulation, fertilization, and successful pregnancy. These disruptions often lead to infertility or pregnancy complications if untreated.
Here’s how thyroid problems affect fertility:
1. Increasing Risk of Early Miscarriage
Imbalanced thyroid hormones affect embryo development and increase the risk of pregnancy loss in the first trimester.
2. Preventing Ovulation
Low thyroid hormone levels can interfere with the release of eggs from the ovaries, making conception difficult.
3. Implantation Issues
Thyroid dysfunction can make it harder for fertilized embryos to implant successfully in the uterine lining.
4. Lowering Estrogen & Progesterone Levels
Both estrogen and progesterone are essential for preparing the uterus and sustaining pregnancy. Thyroid imbalances reduce these hormones, lowering chances of conception.
Conclusion
Thyroid problems are a common but often overlooked cause of infertility. The good news is, with timely diagnosis and treatment, most women can restore hormonal balance and improve their chances of conceiving. If you’re struggling with fertility, it’s important to check your thyroid health.
