If you have been unsuccessfully trying to get pregnant for more than 6 months, before you embark on invasive medical procedures and spend thousands of dollars for assisted reproductive technology, ensure that your thyroid is functioning at its optimum.
Many women don't realize that good thyroid function is necessary for fertility, the ability to conceive and to maintain a pregnancy. An under (or over) functioning thyroid can prevent you from achieving that much desired pregnancy. While there are many and varied reasons for infertility, suboptimal thyroid function may be that "missing link" especially for those with no specific reproductive problems.
A full thyroid evaluation is essential, and should be done as soon as possible for any woman who wants to get pregnant, especially if she:
The thyroid gland is located near the front of the throat, just below the voice box & just above the collar bones. Every cell in the body depends upon thyroid hormones for regulation of the body's metabolism, blood calcium levels, energy production, fat metabolism, oxygen utilization, balance of other hormones & weight maintenance.
Hormones involved with thyroid function include Thyroid Releasing Hormone (TRH) released from the hypothalamus in the brain, which stimulates the pituitary gland at the base of the brain to release Thyroid Stimulating Hormone (TSH) which in turn stimulates the thyroid gland to produce Thyroxine (T4) & Triiodothyronine (T3). Much of T4 is converted to T3 (the active form) in the liver. Thyroid hormones are synthesized from iodine and the amino acid Tyrosine (from protein), and the conversion to the active form is reliant on the trace mineral Selenium.
Healthy Thyroid function can be affected by:
Anovulatory cycles – not releasing an egg / ovulating. This makes pregnancy impossible.
Luteal Phase Problems – With a short second half of the menstrual cycle a fertilized egg can't implant securely and ends up leaving the body at the same time that menstruation would occur (very early miscarriage) & is often mistaken as a regular period.
High Prolactin Levels – due to elevated levels of Thyroid Releasing Hormone (TRH) and low levels of Thyroxine (T4) resulting in irregular ovulation or no ovulation.
Other Hormonal Imbalances – reduced sex hormone binding globulin (SHBG), oestrogen dominance, progesterone deficiency, all of which interfere with proper reproductive hormone balance.
1. Do you have any of the common signs & symptoms associated with low thyroid function?
2. Is your basal temperature consistently below 36.5° C? Take your oral temperature at rest first thing in the morning before moving out of bed for 7 -10 days in the first 14 days of your cycle. Your temperature should be between 36° and 37° C but ideally above 36.5°C.
3. Blood Tests - For full thyroid assessment you require readings for TSH, T4, T3, rT3 & Thyroid Antibodies. TRH may also be required. For optimum fertility, your TSH level should be between 1 and 2. Your doctor or naturopath can order these tests for you.
4. Urinary Iodine - Iodine is a key component of thyroid hormone. Excessive iodine as well as a deficiency of iodine can result in low thyroid function. Your doctor or naturopath can order this test for you.
5. Diet & Lifestyle - Our modern western diet is a major contributor to increasing thyroid health problems. Foods detrimental to thyroid health include refined grains, simple sugars, soy products, peanuts & peanut products, caffeine, hydrogenated oils, cigarette smoking and alcohol. Excessive consumption of vegetables such as cabbage, broccoli, turnips, Brussels sprouts have the ability to block the absorption of iodine.
Exposure to heavy metals e.g. mercury (amalgam fillings) and fluoride (water supply, toothpaste) may also be detrimental.
Stress management is imperative. Stress results in elevated levels of cortisol, the main hormone released by the adrenal glands. Increased cortisol will inhibit the conversion of T4 to the active T3 hormone.
Exercise is beneficial as it will stimulate thyroid hormone secretion and increases tissue sensitivity to thyroid hormones.
Treating thyroid function is not a magic cure for all fertility issues but I have found that for many women, once thyroid health has been improved, their fertility issues were resolved and they have gone on to have a healthy pregnancy and enjoyed the treasures of motherhood.
If you suspect that less than ideal thyroid health may be contributing to your fertility difficulties or just impinging on your health generally, take action now!

My daughter has been trying to get pregnant for 8 years. The doctors and her fertility doctor say she is fine and there isn't any reason she doesn't get pregnant. He husband's tests are great also. I finally asked her to get a full thyroid test. The results came back all normal except for her RT3 is 40.1H, TSH is 2.48. What does she need to do or have done to fix this problem? Could this be the reason she isn't getting pregnant?

I was diagnosed with underactive thyroid last year. Noone in my family has thyroid issues. I am on medication and have been trying to get pregnant. The fertility specialist that we have now seen cannot help us until my thyroid is in normal range. I don't know what is the normal range. He said that my thyroid is 12. What is a 'normal' range to succeed in getting help with fertility? I have been taking 50mg of Eltroxin each morning. Should I be taking more to get it to a normal range?
I have been trying to concieve for 10 yes with no luck, I have been to doctor after doctor and also had my husband checked what can I do...I am 34 and I go tomorrow to check thyroid

My wife is in not safe position because she was suffering from thyroid last one year and she did not conceive regularly
Hi,well I've had Hypothyroidism for almost 3 years now. I was first diagnosed after I had my child, which was 3 years ago and she is 6 now. I was not being treated due to not having insurance. Now iI am insured and finally went to the regular physician about 2 months ago. She prescribed "nature throid 65mg twice a day" I now feel like my body is getting back to normal and lost 20 pounds. As far as not being able to conceive, I have not had protected sex since my daughter was born. My OB told me that I should be able to conceive soon. I am currently waiting to take pregnancy test.only 2 more weeks and I get to find out if I'm pregnant again. Maybe this help some of you. I will be posting in 2 weeks and letting you you guys know how it turned out.

Hi I have a thyroid problem I take levrothy 50mcg everyday,I have a miscarriage in March it is possible I can get pregnant again
My endocrinologist here in Beverly Hills told me your TSH when trying to conceive should be 1 or lower. I've tried for 4 years with a TSH level of 1.3 and then it jumped to 1.69 and now it's 3.6. My reproductive doctor who performed my IUIs, IVFs never told me my levels were off. In fact, all of my doctors said my levels were within normal ranges. Finally I met a fertility guide named Lin Weinberg at Spoken Origins who told me my levels were off. She insisted I get a full thyroid panel. The tests demonstrated my thyroid was having trouble converting T4 to T3 in addition to having a too high TSH. Lin told me I could test me levels without seeing a doctor by going to www.privatemdlabs.com. She was right. While doctors may mean well, not all are up to date with the latest research. Ladies we must be our own advocates in health. Get your levels tested yourself if your doctor won't test you. Yes, you pay out of pocket but well worth it. I think the full panel cost about $250. I took my results to a local doctor who agreed with Lin and has since put me on two different thyroid meds. Fingers crossed I'll be pregnant soon. The doctor believes my levels could get to where they need to be in about 3 months or less. Good luck to everyone. Baby dust to all of you!!!!

I'm 20 year old , I was diagnosed with high tsh level 6.0(reference range used by my lab .35-5.5).And my obg/gyn recommend a half tablet per day (12.5mg half of this).After googling I realised that yoga and diet can help a lot in proper functioning of thyroid gland and hence I started doing yoga in the early morning for a duration of 1hour.And most importantly I "don't have any symptoms of hypothyroidism ".I just had a spotting in between a periods for a duration of 2-3 months and it stopped on its own without any medication I mean to say before I satarted taking that synthetic harmone supplement.Will it affact my future life I mean will I become infertile in future and will my tsh will increase as time lapses .I'm damn scared please do helpme with your suggestions and experience .
I have a thryriod problem but have brought it under control by using taking a tablet every morning. Did my test in June and all in order. Papsmear was normal.
Been trying for 5 months to get pregnant... Period is almost none - just some spotting. Last spotting 27 June. Been trying to get pregnant but all the test are negative.
How long does it take to fall pregnant if one has the thyriod gland under control, live a healthy life style. Dont smoke drink occasionally and eat healthy and expercise daily
