Normally, estrogen's immune stimulatory activity is neutralized by anti-inflammatory actions of progesterone levels. Supplementary Figure 1. J Womens Health Larchmt — Subclinical hypothyroidism and insulin resistance in polycystic ovary syndrome: is there a relationship?

Prolactin and thyroid-stimulating hormone TSH levels rise in hypothyroidism. In turn, prolactin affects the ratio of luteinizing hormone and follicle-stimulating hormone FSH and increased dehydroepiandrosterone DHEA from the adrenal gland. All participants had statistically similar mean age, body mass index BMIwaist circumference, systolic blood pressure BP and diastolic BP.
