Thyroid Hormones And Foetal Development

Can thyroid and PCOS patient get pregnant? | Hormonal Imbalance & Pregnancy – Dr. Prakash Kini

The first endocrine structure to appear during embryonic development is the thyroid gland. At 10-12 weeks of embryo development, follicles containing colloid become visible, and the thyroid is able to incorporate iodine into thyroid hormones. Thyroid hormones are major factors for the normal development of foetal brain, and until the end of the first trimester, when the hypothalamic-pituitary- thyroid axis becomes functional, the foetal brain is strictly dependent on local deiodination of maternal thyroxine -. Thyroid hormone deficiency may cause severe neurologic disorders, resulting from defects in neuronal cell differentiation and migration, axonal and dendritic outgrowth, myelin formation and synaptogenesis . The offspring of women with a serum-free thyroxine concentration in the lowest decile of the reference range at 12 weeks of gestation may have significant delays in neurodevelopment. The mother is the only source of foetal thyroid hormones from conception to approximately 13 weeks of gestation, when foetal thyroid function has developed -.

Vitamin D Requirement During Pregnancy

Thyroidectomised patients often need calcium and D vitamin supplementation, and the treatment needs frequent adjustment during the pregnancy to prevent maternal and neonatal hypocalcemia. During pregnancy vitamin D and calcium metabolism undergo significant changes to provide the calcium needed for maternal skeletal preservation and foetal skeletal formation. Increased intestinal calcium absorption seems to be the primary mechanism for obtaining extra calcium in physiological pregnancy, but frequent nausea and vomiting or sometimes diarrhea reduce the amount of calcium absorbed by the mother .

Vitamin D does not occur naturally in foods. Moreover, the usual recommendations to avoid sun exposure reduces dermal synthesis of vitamin D3 Although vitamin D is undoubtedly important for foetal bone development, we know that it plays a much wider role in health and disease prevention.

Not really a vitamin, D3 is a pro-prehormone made in the skin in response to ultraviolet-B light exposure. It is the precursor to form 25-hydroxyvitamin D3 , a prehormone, which is ultimately converted to 1,25-dihydroxyvitamin D3 , one of the most potent steroid hormones known. 1,252D may interfere with many functions beyond calcium metabolism, such as foetal “imprinting” that may affect neurodevelopment, immune function and chronic disease susceptibility later in life, as well as soon after birth .

Impact Of Thyroid Disease On Fertility And Assisted Conception

Thyroid autoimmunity and/or thyroid dysfunction are prevalent in women of reproductive age and have independently been associated with adverse fertility and pregnancy outcomes, in the case of spontaneous conception or after assisted reproductive technology . Thus, it seems reasonable to screen for thyrotropin and thyroid peroxidase autoantibodies in infertile women attempting pregnancy. However, even if the relationship between fertility and thyroid dysfunction and/or TAI persists when properly controlled for other variables, it remains challenging to claim causation. Several studies with different designs have looked at the association between thyroid autoimmunity, thyroid function and fertility. Heterogeneity among study results are related to small numbers of included patients, poor study design, selection of causes of infertility and different assays used to measure TAI, thyroid hormones and TSH reference values. Indeed, there is no consensus regarding the upper limit of normal for TSH to define thyroid dysfunction and the cut-off levels for intervention. Furthermore, data from interventional trials looking at the impact of levothyroxine treatment on fertility outcome in randomised controlled studies are scarce. Despite the recent update of the guidelines by the American Thyroid Association for the Diagnosis and Management of Thyroid Disease during Pregnancy and the postpartum, many questions remain unsettled in ART.

What Are The Symptoms Of Hypothyroidism

When the thyroid gland produces less thyroid hormone than it should , metabolism slows down and causes a variety of symptoms. At first, the symptoms of hypothyroidism may not be noticed, but over time these symptoms may become more obvious and severe and can include the following:

  • Fatigue
  • Repeated miscarriage

How Does Our Thyroid Function

Can thyroid and PCOS patient get pregnant?

Your thyroid, which is a butterfly-shaped gland in your neck and a critical part of your endocrine system. T The brain will send a particular signal to stimulate your thyroid to produce and release thyroid hormones.

In your brain, the hypothalamus, will secrete a hormone known as thyroid releasing hormone . TRH will then stimulates thyrotrophs in the anterior pituitary to release Thyroid Stimulating Hormone . TSH is then released from the anterior pituitary and will stimulate the thyroid gland to release thyroxine and triiodothyronine . Generally your thyroid will release about 80% T4 and 20% T3.

Both T4 and T4 are released into your bloodstream and circulate throughout your body affecting a variety of different organs. . One of the main organs that requires adequate thyroid hormone is the brain. The brain is continuously monitoring that it is receiving enough thyroid hormone. If the brain senses that it is not getting enough thyroid hormone or there is too much thyroid hormone, the brain can either up-regulate or down regulate how much signal it sends to the thyroid. This is very important to understand because if your brain has to send more or less signal, this will be reflected in your blood work and is often a point of confusion for many patients.

Can Pregnant Women Follow A Natural Thyroid Treatment Protocol

Many women who are pregnant have thyroid conditions. Some of these conditions are a result of the actual pregnancy and are transient in nature, and many times these will self-resolve once the woman gives birth. But for those women who have developed a thyroid condition prior to giving birth, some may wonder whether they can follow a natural thyroid treatment protocol while they are pregnant.

Before I discuss this, let me first say that a woman who has a thyroid condition and is looking to become pregnant should ideally begin a natural thyroid treatment protocol prior to pregnancy. This would be the ideal situation for a couple of reasons. First of all, and as I pointed out in a previous article, there are some women with thyroid conditions who have fertility problems, and are unable to become pregnant in the first place. But by following a natural thyroid treatment protocol, this can greatly improve their chances of getting pregnant. The reason for this is because many women who have fertility issues have a hormonal imbalance, which in most cases can be corrected by following a natural thyroid treatment protocol which is recommended by a competent natural endocrine doctor.

The Vague Symptoms Of Thyroid Disorders

Thyroid hormone regulates metabolism and helps many of our organs to function. Because of this, thyroid problems can cause a wide range of vague symptoms:These symptoms are non-specific and similar to those of a number of other conditions. Some of them also can be related to the rigors of a womans everyday life. Youre busy with family, work, friends, etc. Of course youre tired at times. When theres so much to do that working out or making healthy meals seems impossible, your weight can creep up.I sometimes see patients who when their thyroid hormone test comes back normal admit that they sort of hoped they had a thyroid disorder. It could have been a simple explanation for fatigue and weight gain. Taking a pill may seem easier than making lifestyle changes when theyre so busy already.But, of course, we dont want you to suffer needlessly. Thyroid conditions often can be diagnosed with a blood test to measure thyroid hormone levels. See a doctor if your symptoms:Aside from making you feel sluggish and generally unwell, thyroid disorders can affect family planning as well.

  • Abnormal bowel function
  • Changes in mood
  • Occur in combination
  • Have no identifiable cause
  • Are out of proportion to what you think they should be for example, if youre more tired than you normally would be in your daily activities
  • Dont go away

What Are The Most Common Causes Of Hypothyroidism During Pregnancy

Can thyroid and PCOS patients get pregnant? – Dr. Prakash Kini | Cloudnine Hospitals, Bangalore


Overall, the most common cause of hypothyroidism is the autoimmune disorder known as Hashimotos thyroiditis . Hypothyroidism can occur during pregnancy due to the initial presentation of Hashimotos thyroiditis, inadequate treatment of a woman already known to have hypothyroidism from a variety of causes, or over-treatment of a hyperthyroid woman with anti-thyroid medications. Approximately, 2.5% of women will have a TSH of greater than 6 mIU/L and 0.4% will have a TSH greater than 10 mIU/L during pregnancy.

Can Hypothyroidism Impact Your Fertility

An underactive thyroid can affect your ability to conceive. Heres what to do if you have hypothyroidism and are trying to become pregnant.


When your thyroid gland isnt making enough thyroid hormone, it can have a serious effect on every organ in your body including your reproductive system.

This means hypothyroidism may make it difficult to conceive if youre planning on having children. A study published in August 2015 in the Journal of Pregnancy found that women with hypothyroidism were less likely to become pregnant and more likely to take longer to become pregnant than women without the condition.

Thats because women with hypothyroidism may not ovulate or ovulate with any regularity, and you have to ovulate to get pregnant, says Ingrid Rodi, MD, a gynecologist and reproductive endocrinologist at UCLA Medical Center in Santa Monica, California.

Hypothyroidism can affect fertility in men as well, according to the Thyroid Foundation of Canada. Although hypothyroidism is less common in men, those who do have an underactive thyroid may have low libido and low sperm count, according to a review of research published in November 2013 in Frontiers in Endocrinology in November 2013.

Additionally, hypothyroidism can lead to fatigue in both men and women. When youre fatigued, you may not have much sex, Dr. Rodi says. Its harder to get pregnant when youre not having much sex.

What Expectant Moms Need To Know

Whether a pregnant woman finds out she has thyroid cancer or a thyroid cancer survivor is hoping to become pregnant, the concerns that come with having a child may be compounded by a new or previous diagnosis. Crafting a treatment plan or an approach to pregnancy that will keep a mother and her baby safe starts with understanding the necessary precautions. For families and medical teams, information and attentiveness can ease the journey ahead.

Morning Sickness And Reverse T3

In extreme cases of Gestational transient thyrotoxicosis , hCG-stimulated hyperthyroidism can cause Hyperemesis gravidarum .

In this HG syndrome, the mother experiences an extreme version of morning sickness continual vomiting, weight loss, and dehydration.

These certainly sound like some of the symptoms of thyrotoxicosis in Graves disease.

However, while TSH and Graves disease antibodies tend to enhance T3 secretion more than T4 from the thyroid gland , hCG enhances T4 secretion more than T3 , enabling doctors to distinguish between GTT and Graves autoimmune hyperthyroidism.

In hyperthyroid HG patients who are ill and losing weight, their higher T4 levels lead to much higher levels of Reverse T3.

RT3 increased in HG by an average of 31% higher than healthy pregnant controls in a study by Juras et al, 1983.

Because GTT and even its more severe form HG usually fade by the beginning of the second trimester, it is rarely treated except with fluids and electrolytes and a short course of propranolol to reduce hyperemesis and thyrotoxicosis.

How Is Hypothyroidism Treated

The most commonly used medication to treat hypothyroidism is called levothyroxine. Levothyroxine is a tablet that is usually taken once a day. Once you start taking levothyroxine, you should have your blood checked in 46 weeks to measure the level of thyroxine and to make sure you are taking the right dose.

How Long Is The Treatment For

For most people, treatment is for life. Occasionally, the disease process reverses. This is uncommon, apart from the following:

  • Children. Sometimes hypothyroidism is a temporary condition in older children.
  • Pregnancy. Some women develop thyroid imbalance after having a baby. If it occurs, it typically happens about three to six months after the birth. Often this lasts just a few months and corrects itself. Treatment is needed only in a small number of cases. However, afterwards it is wise to have a yearly blood test, as there is an increased risk of developing autoimmune thyroiditis and long-term hypothyroidism in the future.

What Are The Symptoms Of Postpartum Thyroiditis

The hyperthyroid phase often has no symptomsor only mild ones. Symptoms may include irritability, trouble dealing with heat, tiredness, trouble sleeping, and fast heartbeat.

Symptoms of the hypothyroid phase may be mistaken for the baby bluesthe tiredness and moodiness that sometimes occur after the baby is born. Symptoms of hypothyroidism may also include trouble dealing with cold dry skin trouble concentrating and tingling in your hands, arms, feet, or legs. If these symptoms occur in the first few months after your baby is born or you develop postpartum depression, talk with your doctor as soon as possible.

What About Women Who Had A Thyroidectomy

After undergoing thyroidectomy, or removal of the thyroid, thyroid hormone is maintained with a daily pill of synthetic hormone. Women who become pregnant will need an increased dose of synthetic thyroid hormone, beginning as early as six weeks into pregnancy. If expectant mothers are taking prenatal vitamins or iron or calcium supplements, they should take the vitamins 45 hours before their thyroid medication to maximize effectiveness. After delivery, mothers can return to their normal dose of thyroid hormone.

What Is Liothyronine

Hyperthyroidism and Getting Pregnant

Liothyronine is a manufactured form of triiodothyronine . Armour Thyroid® contains both T4 and T3 and is extracted from the thyroid gland of pigs. It contains about four times as much T4 as T3. In humans, the usual ratio of T4 to T3 is 14 to 1, so Armour Thyroid® extract has a much higher proportion of T3 than humans usually have.

UK guidelines recommend that T3 and combinations of T4 and T3 should not routinely be prescribed. The Royal College of Physicians does not recommend that T3 should ever be prescribed. It says there is not enough evidence that it helps patients and not enough evidence to be sure it is not harmful. Clinical practice guidelines worldwide do not recommend or support the routine use of combination therapy.

The NHS recommends that:

  • Treatment with liothyronine should never be started in primary care .
  • Patients who are currently taking liothyronine should be reviewed by a consultant NHS endocrinologist with a view to switching to levothyroxine if appropriate.
  • The British Thyroid Association states that a small number of patients have symptoms which do not improve on levothyroxine. For these, a consultant NHS endocrinologist may recommend a carefully monitored trial of liothyronine.
