Association Between Serum Thyroid-stimulating Hormone (TSH) and Intracytoplasmic Sperm Injection (ICSI) Outcome in Women Undergoing ICSI

Overview

TSH has been suggested to be involved in reproductive challenges such as ovulatory issues, infertility, miscarriage, and maternal complications for many years. Multiple studies have associated thyroid function with ovarian function and reproductive physiology. The thyroid hormone can impact follicle development, as well as the metabolism of estrogen and androgen, the menstrual cycle, and the receptivity of the endometrium

In a region with adequate iodine levels, a TSH threshold of 4.12 mIU/L should be regarded as the upper limit of normal. The Chinese Society for Reproductive Medicine suggests that infertile women and those trying to conceive should consider a TSH level between 4-4.5 mIU/L for subclinical hypothyroidism. Hence, it is recommended that women aiming for in vitro fertilization (IVF) should have a TSH level of 4 mIU/L or lower. Studies have shown that infertile patients with untreated TSH levels \>2.5 mIU/L before IVF/intracytoplasmic sperm injection (ICSI) had better pregnancy results when their TSH levels were \<2.5 mIU/L compared to those with TSH \>2.5 mIU/L. In this study the aim was to Examine the clinical characteristics and results in infertile individuals with varying thyroid stimulating hormone (TSH) levels during ICSI, and determining which TSH levels cutoff impact the outcomes of ICSI or not.
