Ovarian stimulation does not induce thyrotropin receptor autoantibodies in women with thyroid autoimmunity

Eur J EndocrinolPublished Prospective pilot study

Study context

Population
Women of subfertile couples with thyroid autoimmunity (TAI) undergoing OS for assisted reproductive technology (ART); mean (SD) age 38.8 (±3.2) yearseleven cycles in TAI
Participants
10 vs 1
Exposure
Before vs after ovarian stimulation
  • TAIn = 10
  • Without TAIn = 1
Outcome
Presence of binding and functional (stimulating or blocking) TSH-R-Ab, five assays
Follow-up
Before and after OS

Main finding

As reported in the abstract

TSH-R-Ab · before or after OS
  • TSH-R-Ab in all samples below the cut-off of the immunoassay and four bioassays before or after OS

Observational data: associations, not effects.

Further findings

Oestradiol during OS

Oestradiol increased from 40 (26-56) ng/L to 963 (383-5095) ng/L
P < 0.01

Cumulative OS dose

Median (range) cumulative OS dose, IU/L
1413 (613-2925)

Baseline thyroid tests · median baseline

Median TSH, mIU/L
2.33 (2.23-2.61)
Median free thyroxine, pmol/L
16.8 (14.4-18.5)
Median TPOAb, kIU/L
152 (86-326)
