The article examines the cause of low thyroid-stimulating hormone (TSH) level with a normal free T4 level. The decrease TSH level seen in subclinical hyperthyroidism is caused by the pituitary's response to minor elevations in serum or tissue T4 and T3 levels. In the evaluation and treatment ...
Forest plot of the low vs. middle categories of TSH levels and dementia. Two subgroups were analyzed: TSH levels below vs. within the normal range and the lower vs. middle tertiles of TSH levels within the normal range. The estimated RRs and 95% CIs are plotted with boxes and horizontal ...

Thereafter TSH increases progressively reaching its maximal level during the last trimester of gestation. With the termination of labor TSH drops abruptly to normal limits 24 hr after delivery. A marked difference is established between maternal and fetal TSH concentration. The elevation of TSH during...
Women randomized to the intervention group began levothyroxine treatment between 2 and 4 weeks before the controlled ovarian hyperstimulation and continued through the end of pregnancy. For individuals with a TSH level of 2.5 mIU/L or higher, the starting dose was 50 μg/d; for those with a ...
Follicular cell activity level is regulated by the thyroid-stimulating hormone or thyrotropin (TSH) pro- duced by the anterior pituitary gland and released in turn under the control of thyrotropin-releasing hormone produced in the hypothalamus and responding, with negative feedback, to serum levels ...

T4 fell to 1.6 @g% but TRH induced TSH release indicating hypothalamic deficiency and this was treated with L-T4 replacement. ACTH was normal (metyrapone test). FSH (390 ng% LER 907) and LH (96 ng%) were normal adult. Menarche at age 9 years was followed by amenorrhea. The data ...
