Kris Poppe, Candice Autin, Flora Veltri, Pierre Kleynen, Lidia Grabczan, Serge Rozenberg, Lieveke Ameye
Background: Since 2010, three meta-analyses have been published on the impact of thyroid autoimmunity (TAI) on pregnancy outcomes in infertile women treated with assisted reproductive technology (ART). The initially observed high risk of miscarriage became very low in the most recent meta-analysis published in 2016. Objective: To investigate whether the lower risk of miscarriage in the latest meta-analysis was associated with the increased use of intracytoplasmic sperm injection (ICSI) in recent studies...

The influence of thyroid autoimmunity in assisted reproductive technology (ART) outcome in euthyroid women is still controversial. In this study, we retrospectively evaluated embryo quality in 123 euthyroid women undergoing ART with or without thyroid autoantibodies (TAA). Embryo quality was assessed in 119 embryos of 29 infertile patients with TAA and in 394 embryos of 94 infertile patients without TAA. Our results showed not statistically significant differences in age, body mass index, anti-Müllerian hormone, follicle stimulating hormone, free triiodothyronine, and free thyroxine levels between cases and controls...

BACKGROUND AND OBJECTIVE: Infertility is a common disease that in about one third of cases has a female cause and often requires assisted reproduction technologies (ART) to conceive. Also thyroid autoimmunity (TAI), with or without hypothyroidism, is a common disease, particularly in females, and referral for endocrine consultation is not infrequent. DISCUSSION: In the last 15 years a remarkable amount of studies has been published that investigated the pathophysiology of women suffering from TAI, who undergo ART...

AIM: Thyroid dysfunction and autoimmunity are associated with an adverse effect on fertility. An aberrant high thyroid stimulating hormone level is associated with diminished ovarian reserve in women of reproductive age; however, the utility of levothyroxine (LT4) replacement for infertile patients with subclinical hypothyroidism is still under discussion. The aim of this study was to investigate whether LT4 supplementation for infertile patients with subclinical hypothyroidism improves impaired ovarian function...

Understanding of changes in thyroid function and the consequences of thyroid disease during pregnancy has rapidly grown in the past two decades, and revised American Thyroid Association guidelines on this topic were published in 2017. This Review explores the association between thyroid autoimmunity and complications during and after pregnancy. Thyroid autoimmunity refers to the presence of antibodies to thyroperoxidase or thyroglobulin, or thyroid-stimulating hormone receptor antibodies (TRAbs), or a combination of these, and is present in up to 18% of pregnant women...

Importance: Presence of thyroid autoantibodies in women with normal thyroid function is associated with increased risk of miscarriage. Whether levothyroxine treatment improves pregnancy outcomes among women undergoing in vitro fertilization and embryo transfer (IVF-ET) is unknown. Objective: To determine the effect of levothyroxine on miscarriage among women undergoing IVF-ET who had normal thyroid function and tested positive for thyroid autoantibodies. Design, Setting, and Participants: An open-label, randomized clinical trial involving 600 women who tested positive for the antithyroperoxidase antibody and were being treated for infertility at Peking University Third Hospital from September 2012 to March 2017...

Aberrations in reproductive fitness may be a harbinger of medical diseases in men. Existing data suggest that female infertility is associated with autoimmune disorders; however, this has not been examined in men. As immune surveillance and hormonal factors can impact male fertility and autoimmunity, we sought to determine the association between male infertility and incident autoimmune disorders. We analyzed subjects from the Truven Health MarketScan claims database from 2001 to 2008. Infertile men were identified through diagnosis and treatment codes...

Thyroid autoimmunity (TAI) appears to play a crucial role in female infertility, recurrent pregnancy loss and IVF failure. Thyroid autoantibodies against thyroid peroxidase and thyroglobulin have been shown to represent an independent risk factor for infertility and miscarriage. Moreover, thyroxin hormone administration reduces the risk of obstetrical complications in TAI positive women. The aim of our present study was to investigate the immunological background of female infertility and recurrent pregnancy loss in euthyroid and subclinical hypothyroid women with TAI focusing on innate immunity...

Breast Cancer (BC) has associated risk factors and genetic factors like BRCA1, and BRCA2. Many benign and malignant disease processes are found concurrently with BC and believed to be additional risk factors like gall bladder stones (cholelithiasis), hypertension, diabetes mellitus, cerebrovascular lesions, arthritis, spine and spinal cord degenerative lesions, infertility, depression, sleep disturbances, obesity, autoimmune diseases (SLE), and thyroid diseases. There are some malignant disease associations like synchronous or metachronous ovarian, colonic and endometrial tumours with Breast cancer...

BACKGROUND: While screening of thyroid peroxidase antibody (TPOAb) has been recommended in women with primary ovarian insufficiency, the relationship between thyroid autoimmunity (TAI) and ovarian reserve remains undetermined. Because the TAI prevalence was reported to be different between different ethnic/racial groups, this study aimed to investigate the TAI prevalence in Chinese women with variable ovarian reserve. METHODS: This is a cross-sectional study conducted in a university infertility clinic between October 2013 and March 2016...

Extrahepatic manifestations of hepatitis C virus (HCV) infection are a rare but serious condition. This article summarizes the current literature on the association between HCV and endocrine and pulmonary manifestations, as well as idiopathic thrombocytopenic purpura (ITP). HCV may directly infect extrahepatic tissues and interact with the immune system predisposing for obstructive and interstitial lung disease, ITP, autoimmune thyroiditis, infertility, growth hormone and adrenal deficiencies, osteoporosis, and potentially lung and thyroid cancers...

BACKGROUND: Thyroid autoimmunity may be linked to infertility, in both thyrotropin (TSH)-dependent and TSH-independent fashion. The aim of the present study was to assess this presumed reciprocal relationship of thyroid autoimmunity and pregnancy. METHODS: TSH and antithyroid peroxidase autoantibodies (anti-TPO) were evaluated retrospectively over an eight-year period in 444 Greek women who had previously none or at least one pregnancy (>28 weeks). Statistics were done with analysis of co-variance (ANCOVA) and the Chi square test...

This study evaluated the effects of comorbid disorders of diabetes and hyperthyroidism in the adult male mice. In total, 32 ICR strain mice were equally distributed into four groups: control (C), diabetic (D), diabetic-plus-hyperthyroid (DH), and hyperthyroid (H). Mice allocated for diabetes received a single intraperitoneal injection of streptozotocin (STZ) at 200 mg/kg body weight. At the onset of diabetes, one group of mice was concomitantly injected levothyroxine (LT4; 0.3 mg/kg body weight) and the other set of animals received the same treatment independently on a daily basis...

INTRODUCTION: Thyroid autoimmunity can have an adverse impact on the outcome of the pregnancy. Although the adverse effects of antithyroid antibodies have been well studied in hypothyroid women, their effects in euthyroid women are not well evaluated. AIM: The study was conducted to assess the overall prevalence of anti-Thyroid Peroxidase (anti-TPO) antibodies in pregnant women and the effect of anti-TPO positivity on the outcome of pregnancy in euthyroid women...

Thyroid hormones are important for normal reproductive function, and maternal thyroid dysfunction has been associated with infertility, miscarriage, preterm birth, and poor neurodevelopment in the offspring. Thyroid autoimmunity is the leading cause of thyroid dysfunction in women of reproductive age. Women with thyroid autoimmunity, even with normal thyroid function, appear to be at a higher risk for poor reproductive outcomes, including miscarriage and preterm birth. Thyroxine replacement in women with thyroid autoimmunity with or without appreciable thyroid dysfunction may improve pregnancy outcomes...

Subclinical hypothyroidism has been found to be associated with adverse reproductive outcomes, such as infertility, miscarriage, preterm birth, and complications of pregnancy. Multiple studies have investigated the relationships between thyroid function, thyroid antibodies, fertility, and pregnancy. Thyroid autoimmunity is the most common cause of hypothyroidism in iodine-sufficient locations. Thyroid antibodies have been associated with adverse reproductive outcomes such as miscarriage and infertility. Debate exists regarding the method of identification of thyroid dysfunction in pregnancy, which can be conducted by targeted screening or by universal screening...

BACKGROUND: Thyroid autoimmunity (TAI) is the most frequent autoimmune condition and the first cause of thyroid dysfunction among women of reproductive age. Notably, it has been associated with adverse obstetric outcomes during all trimesters of pregnancy. Furthermore, since most studies show an increased prevalence of TAI among women attending infertility clinics, a detrimental impact of this condition on natural fertility and on the rate of success of assisted reproductive techniques has been suggested...

Polycystic ovarian syndrome (PCOS) is the most prevalent endocrine disorder affecting females. It is a common cause of menstrual irregularities and infertility during reproductive age. Genetic and hormonal factors play crucial role in the pathogenesis of PCOS. Low level of progesterone in PCOS causes overstimulation of immune system that produces more estrogen which leads to various autoantibodies. Different autoantibodies have been documented in PCOS, for example, anti-nuclear (ANA), anti-thyroid, anti-spermatic, anti-SM, anti-histone, anti-carbonic anhydrase, anti-ovarian, and anti-islet cell antibodies...

BACKGROUND: Thyroid dysfunction is the most common autoimmune endocrine disorder in women of reproductive age, and is associated with menstrual irregularities, anovulation and infertility. Whether it is thyroid function or thyroid autoimmunity that affects functional ovarian reserve (FOR, i.e., the small growing ovarian follicle pool) reflected in anti-Müllerian hormone (AMH) has, however, remained under dispute. METHODS: We investigated in 225 infertile women whether thyroid function, after adjustment for thyroid autoimmunity, affects FOR within what is considered normal thyroid function (TSH, 0...
