In summary, the study revealed that the presence of TAI did not affect embryo quality and pregnancy outcomes but decreased the number of oocytes received and birth weight in twin pregnancy. A total of 16481 patients with infertility were referred to the Reproductive Center of Peking University Third Hospital for their first IVF/ICSI treatment between January 2018 and June 2019. However, all the aforementioned studies failed to show any association between the presence of thyroid antibodies and the number of oocytes retrieved, fertilization rate, or implantation rate. 2018;103(5):1755-66. (2018) [38] found no difference in MR when analyses were strictly restricted to CPs, entirely in keeping with our findings. investigated different thyroid functions in women with or without TAI during COS and demonstrated a significant difference in TSH levels between the two groups (16). Approved as a pharmacy medicine, Sanofi will launch Cialis Together in the second half of the year. Given the powerful influence of female age on pregnancy outcome through effects on oocyte quality [20], a critically important strength of our study was to restrict analyses to papers that reported female age. However, we could not detect the difference in thyroid function between the two groups during COS due to the studys retrospective design. Results showed no significant difference in number of embryos transferred between TAI+ and TAI- euthyroid women (SMD 0.07; 95%CI [0.13, 0.23]; P=0.49; 3 studies; I2=0%). Further prospective studies are needed to illustrate the mechanisms underlying the impact of TAI on follicle development and fetal growth. Subgroup analysis showed no association between the types or titers of thyroid antibodies and adverse IVF/ICSI outcomes. HH conceived and designed the project, assisted with data interpretation, manuscript drafting, manuscript revision and critical discussion. We found no difference in any pregnancy outcomes in relation to TAI status. Patients were also ineligible if they had abnormal thyroid function testing, except for thyroid antibody positivity, before IVF/ICSI treatment.

There were no significant differences between the two groups in the protocols and gonadotropin dose of COS, hormone levels on the day of HCG trigger, endometrial thickness, fertilization procedures, timing of embryo transfer, the number of good-quality embryos or embryos transferred. After adjusting for thyroid function, anti-Mllerian hormone levels, basal follicle stimulating hormone levels, basal estradiol levels and antral follicle count, the number of oocytes retrieved in the TAI group was significantly lower than that in the control group.

Write a review. There is no association between the presence of anti-thyroid antibodies and increased reproductive loss in pregnant women after ART: a systematic review and meta-analysis. Several studies have reported the association between thyroid autoimmunity (TAI) and in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes. Hum Reprod Update. There have been a number of alternative theories regarding ICSIs ability to overcome the adverse effects of TAI on pregnancy outcomes. 1 Citations Metrics Abstract Background Thyroid autoimmunity (TAI) has been demonstrated to be associated with adverse pregnancy including recurrent miscarriage, unexplained infertility, and implantation failure. Results showed no significant difference in TSH levels between TAI+ and TAI- euthyroid women (SMD 0.14; 95%CI [0.07, 0.34]; P=0.19; 5 studies; I2=46%). However, each had varying inclusion criteria, and in recent a recent meta-analysis, TAI has been shown to be more prevalent in conditions associated with poor IVF outcomes such as PCOS [43]. Individual studies assessed different antibodies (TPO-Ab and/or TG-Ab) and used different assays as well as different cut-off values for defining TAI positivity (Table 1), which could potentially affect outcomes. Different TH levels between women with and without TAI may provide a possible explanation for the decreased number of oocytes retrieved in patients with TAI. [ 31 , 32 ] In one of the meta-analysis, [ 32 ] 12 studies reported that the ratio of miscarriage was 1.44 (95% CI 1.06-1.95, P = 0.02) in AITD women compared with . Indeed, the study was powered against a predicted CMR of 30% for TAI+ women but unexpectedly, the actual MR in their untreated TAI+ arm was only 10.6%, which was no higher, and indeed, somewhat lower than the background rate of ~15% for women of a similar age [18, 19]. We performed a large-scale retrospective cohort study to verify the effect of the presence of thyroid antibodies on IVF/ICSI outcomes and fetal growth and to evaluate the association between the types and titers of thyroid antibodies and adverse IVF/ICSI outcomes. The synthetic hormone works like the T-4 hormone naturally produced by the thyroid. Biochemical pregnancy loss in IVF is estimated to have an incidence of up to 22% [17], compared to clinical miscarriage which has an incidence of ~15% [18, 19]. 2016;36(2):2137. It is conceivable that very early post-implantation pregnancy stages might have a different vulnerability to these threats than later stages. (2016) [10] found no association between TAI positivity and clinical pregnancy, miscarriage rate or delivery rate in euthyroid women, they did find that women with subclinical hypothyroidism (SCH) and TAI were at greater risk of miscarriage and had a lower delivery rate than TAI- women, indicating that the extent of associated thyroid dysfunction, rather than TAI per se, could account in some part for adverse outcomes reported in previous studies.

In conclusion, the presence of TAI in patients with infertility did not impair embryo quality or affect pregnancy outcomes, including clinical pregnancy, miscarriage, preterm delivery, and live birth. performed a comprehensive analysis on the association between TAI and IVF/ICSI outcomes (2), and they concluded that the presence of thyroid antibodies exerted detrimental effects on pregnancy outcomes, including an increased risk of miscarriage and a decreased frequency of live birth. Thirdly, since the last meta-analysis, at least 4 further studies analysing women of known ages have been published [21,22,23,24]. For the first time, we use strict criteria to analyse BPL and CMR as well as LBR on a per-cycle and per-CP basis in euthyroid women as well as in a larger group, which included women with SCH. Litwicka K, Arrivi C, Varricchio MT, Mencacci C, Greco E. In Women With Thyroid Autoimmunity, Does Low-Dose Prednisolone Administration, Compared With No Adjuvant Therapy, Improve. It is therefore possible that previous negative effects on pregnancy outcomes in TAI+ women may have been due to SCH, rather than TAI itself. Jin L, Wang M, Yue J, Zhu G-J, Zhang B. Continuous data are shown as mean (standard deviation [SD]) for normally distributed data and median (interquartile range) for non-normally distributed data. Fertil Steril. We note, however, that the results of the present study do not support this notion since we found no association between TAI and pregnancy outcome either in euthyroid women or the overall group. Results showed no significant difference in clinical pregnancy rates in TAI+ and TAI- euthyroid women (OR 0.88; 95%CI [0.69, 1.12]; P=0.29; 10 studies; I2=32.0%). Analysis of the 13 remaining studies revealed no significant differences in patient age between all TAI+ and TAI- women (SMD 0.12; 95%CI [0.04, 0.28]; P=0.15; 13 studies; I2=76%) (Fig. An additional 45 articles were excluded (Fig. 10b).

Thyroglobulin and thyroid peroxidase function as key factors in the process of thyroid hormone (TH) biosynthesis and constitute the major thyroid autoantigens involved in the pathophysiology of TAI (3). There were also limited details on individual patients such as stimulation protocols used, which could theoretically affect results given that antagonist and agonist protocols could have different effects on thyroid function [44]. First, our study was a retrospective study; thus, the presence of biases involved in retrospective data collection cannot be excluded. Two meta-analysis results showed that women with thyroid antibody positive who received assisted reproductive assist treatment had a significantly increased risk of miscarriage. Introduction.

In addition, subgroup analysis was performed to demonstrate whether different types and titers of thyroid antibodies had different effects on IVF/ICSI outcomes. It is notable in this regard that the 2011 meta-analysis identified an increased odds ratio (OR) for miscarriage of 3.15 amongst TAI+ women [9] whereas in Busnelli et al. ). Assisted Reproduction and Thyroid Autoimmunity: An Unfortunate Combination. Subgroup analysis did not find any significant difference among these three groups and the control group in the rates of clinical pregnancy, miscarriage, live birth, and preterm delivery or live birth weight in singleton pregnancy ( Mrs. Nettle is a 35-year-old woman who has been trying to conceive for the past 6 months. 2019;380(14):131625.

Results showed no significant difference in clinical miscarriage rate between TAI+ and TAI- euthyroid women (OR 1.18; 95%CI [0.52, 2.64]; P=0.69; 7 studies; I2=54%). Is there an effect of thyroid autoimmunity on the outcomes of assisted reproduction? Thus, a stronger thyroidal response to HCG is needed in twin pregnancy to maintain higher TH. PubMed Lastly, our study did not investigate the use of levothyroxine because of the retrospective design; however, our previous study has shown that the use of levothyroxine did not affect IVF/ICSI outcomes (32). There has been another recent meta-analysis that did not consider the full breadth of IVF patients as we did here, but instead focused only on studies in which ICSI was performed for fertilisation [38]. J Obstet Gynaecol. MW undertook statistical analyses, interpreting data and manuscript drafting. There were no significant differences between the TAI and control groups in the rates of clinical pregnancy (44.2% vs. 45.1%, P = 0.721), miscarriage (14.5% vs. 14.2%, P = 0.916), live birth (37.8% vs. 38.7%, P = 0.715), or preterm delivery (16.0% vs. 15.6%, P = 0.901), even after adjusting for FT4 and TSH levels, as well as the types of thyroid antibodies ( aThe control and TAI groups were matched at a ratio of 1:1 according to age. Thyroid autoimmunity (TAI), defined by the presence of circulating antithyroid antibodies targeting thyroid peroxidase (TPOAb) and thyroglobulin (TgAb), is prevalent among women of reproductive age and is the most frequent cause of thyroid dysfunction. roid antibodies have also been established by the NHANES III population (8). 5 7). 2019;13(5):QC05-08. A number of the included studies reported no significant difference in cause of infertility between the TAI+ and TAI- groups.

On the other hand, our findings are consistent with those of He et al. a Overall association between thyroid autoimmunity and likelihood of clinical pregnancy. There were also no significant age differences between the sub-group of TAI+ and TAI- women who were euthyroid (SMD 0.13; 95%CI [0.10, 0.36]; P=0.25; 10 studies; I2=82%)(Fig. Consequently, it only contained 4 studies, 3 of which had been included in the earlier meta-analysis by Busnelli et al. b Association between thyroid autoimmunity and number of oocytes retrieved in euthyroid women.

Table8 Here we undertook an updated systematic review and meta-analysis of the overall relationship between TAI and IVF/ICSI outcomes as has been done previously, as well as separate analyses of euthyroid women of known female age using strict criteria for defining pregnancy outcomes. Oocyte retrieval was performed 34 to 36 hours after HCG administration. Although a higher ovarian reserve was observed in patients with TAI, the number of oocytes retrieved was significantly lower in patients with TAI than in controls after adjusting for the levels of AMH, basal FSH, basal E2 and FT4, and TSH and antral follicle count. From the 598 articles yielded in the search only 44 relevant articles ultimately fulfilled the inclusion criteria and were qualitatively analyzed.

Euthyroid women with autoimmune disease undergoing assisted reproduction technologies: the role of autoimmunity and thyroid function. One study reported age as the median (25th75th) [15] and could not therefore be included in our analysis of mean ages. (2016) [6] were published prior to 2010. Moreover, the sample sizes in the studies included in this meta-analysis were all small, and the conclusions in those studies were controversial.

The numbers of embryos transferred could also impact pregnancy outcomes. Rao M, Zeng Z, Zhou F, Wang H, Liu J, Wang R, et al. The results of the present study suggest that TAI has no effect on pregnancy outcomes in women undergoing IVF either overall, or in euthyroid women. Moreover, they collected the follicle fluid in women after oocyte retrieval and detected the presence of TPOAb and TGAb in the follicle fluid in women with TAI. Am J Reprod Immunol. It is clear that treating overt hypothyroidism (high TSH and low T4) improves the success of pregnancies achieved through ART and decreases the miscarriage rate. Our results contrast with previous meta-analyses showing increased MR and/or decreased LBR in TAI+ women overall and in euthyroid women undergoing IVF/ICSI [6, 8, 9].
