Thyroid autoimmunity(TAI) per se have adverse effect on pregnancy outcomes，and aspirin and prednisone were used frequently in antithyroid antibodies(ATA) positive infertile women in clinical practice, but the impact of these medicines is still controversial. Therefore, aim of the study was to investigate whether or not the treatment of prednisone in addition to aspirin was capable of improving reproductive outcomes in euthyroid infertile women.

A multicenter retrospective study performed during the period of 2017 to 2020 and euthyroid infertile women positive for anti-thyroperoxidase antibody (TPOAb) and/or thyroglobulin antibody (TgAb) alone with thyroid stimulating hormone 0.35-4.0mIU/L undergoing first in vitro fertilization and embryo transfer(IVF-ET) cycle were recruited in our study.Data analysis was performed using the Statistics Package for Social Sciences.In the end, the value of prednisone plus aspirin treatment was investigated to make a big contribution on clinical practice.

Inclusion Criteria:

1. Both TPOAb and TgAb in all the subjects were measured before ART procedure
2. Thyroid stimulating hormone (TSH) level ranged from 0.35-4.0mIU/L
3. Women underwent first embryo transfer without previous IVF history.

Exclusion Criteria:

1. Abnormal thyroid function test
2. Women with known autoimmune diseases or clinical presentations of autoimmune disorders

we investigate pregnant women

Both TPOAb and TgAb in all the subjects were measured before ART procedure, and their thyroid stimulating hormone (TSH) level ranged from 0.35-4.0mIU/L and also they all underwent first embryo transfer without previous IVF history.
