Conceiving a baby is a complex thing. It is even more complex is to find the reasons behind the inability to conceive. There are many couples who seem to be perfectly healthy by all means and still not able to conceive. These are the cases of unexplained infertility.

Recent studies reveal that the functioning of the thyroid glands of a woman has more say in this matter than expected. Technically, the women may have healthy thyroids. But they might be functioning at the lower level of the normal range. This mild low thyroid levels may affect the normal functions and that could affect the fertility of the women.

What Is A Mild Low Thyroid Level?

The mild low thyroid level is the functioning of the thyroids at the lower level of the normal range. The thyroid test readings would show that it is within the normal range. But when it is closer to the lower line, it might as well be hypothyroidism. Technically it may not have reached this point, but this level can affect the same way hypothyroidism would.

One of the factors this condition can affect is the fertility, especially in women. A woman’s body needs to have many certain working adequately to be able to conceive. A healthy and normal woman should be able to conceive a baby, complete the gestation period and be able to deliver a healthy baby. The major factor that helps complete all of these is thyroid glands. When these glands fail even the slightest, it can affect the fertility or the growth of the fetus.

Mild Low Thyroid Level And Fertility

Thyroids and the hormones produced by these glands are responsible for the menstrual period and ovulation in women. Any alteration in its function will result in low hormone levels. When there are not adequate hormones, the ovaries fail to produce the egg and affect the fertility. It is crucial to solving the thyroid related problem before you can or should conceive.

The TSH Factor

A person with a mild low thyroid level will have normal range of T4 hormones and a slightly-over level of the thyroid stimulating hormone (TSH). The TSH is produced by the pituitary gland to stimulate the thyroids to release more hormones. When the thyroid fails to release the required amount of hormones, the pituitary produces more of TSH to urge the thyroids.

A higher than normal level of TSH is an indication of not-so-normally-functioning-thyroids. For the mild low thyroids, the TSH would just be over the normal range and not overly up as in the case of clear hypothyroidism. There are a few quick and easy steps you can take to rectify this slight problem before it gets overboard.

The Possible Treatments

Since the general hormone therapy is not required for such mild low thyroids, it is up to the lifestyle changes to do the major part. This can help to a great extent and improve the fertility of such women. Since it is not conclusive whether or not such women be treated as hypothyroidism cases, as these women are prone to develop hypothyroidism when they get pregnant. They will need an above normal performance from the thyroids to keep up with the needs of the fetus and mother together.

Once conceived, the thyroid glands of the woman should step up its functions and release more hormones to the requirement fulfillment. An underperforming thyroid or the one that has issues should be treated beforehand. The only thing undecided with this research is the clear path for treatment.

Some researchers say that these women should be treated for the thyroid problems. Some others have the opinion that the problem with thyroids would be some underlying issues or deficiency of certain nutrients. Either way, the clear conclusion is to rectify the problem to improve the fertility of the woman before she can conceive.

The suggested methods are hormone therapy which comes as the last resort, providing supplements for the thyroids and to look for the possible underlying issues.

Diet For Healthy Thyroid Functioning

Thyroid glands are something that can find a problem with what we eat. Nutrients have a higher influence on these glands.

Food to avoid

There are certain foods that affect these glands negatively and interfere with the hormone production or the general smooth functioning. Avoiding these foods should be the first step to do. A few of such problematic foods are


Cruciferous vegetables like broccoli, kale, cauliflower, cabbage, Brussels sprouts etc. You need to completely avoid these items but eat only in mild or moderate quantities.

  • Gluten-containing foods
  • Fatty foods
  • Too much sugars
  • Cheese and other processed foods
  • Too much caffeine, alcohol, and smoking

What you need to eat more

Now is time for the foods that you need to have more in the diet or are an essential part of the thyroid diet.

  • Dairy products like milk, low-fat yogurt etc contain iodine in them. The cattle are given iodine based food so that reflects in the milk production as well. This is the best way to incorporate iodine into the body that helps improve the thyroids and thus the fertility.
  • Adding a little beef or chicken in the diet can add zinc to the diet. It is needed especially if there are any GI problems prevailing.
  • Eggs can provide both iodine and selenium which are most important for thyroids. Eat one whole egg a day unless you are advised not to.
  • Berries are another source of iodine and selenium. The antioxidants in the berries can prevent the oxidation of thyroid cells.

Bottom Line

There could be many reasons for unexplained infertility. The mild low thyroid levels could just be one of them. Solving the thyroids can be the stepping stone to new possibilities. At the same time, it is also essential to solving the problems associated with thyroids, to stay healthy. This new research has definitely come as a clear ray of hope for many who suffer from these unexplained infertility issues.
