Effects of controlled ovarian stimulation on thyroid stimulating hormone in infertile women

ConclusionGnRH-a can significantly increase serum TSH levels with possible development of subclinical thyroid dysfunction. Infertile patients with serum TSH > 2.5mIU/L are more susceptible to GnRH-a while patients with basal TSH less than 2.5mIU/L may get a higher clinical pregnancy rate when receiving IVF/ICSI.
