Association between Maternal Thyroid Hormone Level and Fetal Weight

Association between maternal and fetal weight gain: cohort study.

CONTEXT AND OBJECTIVE Excessive gestational weight gain is related to many complications (both maternal and fetal), such as macrosomia. The most common complications in macrosomic fetuses include: increased risk of intrauterine death, need for intensive care, fractures, neonatal hyperbilirubinemia, paralysis of the brachial plexus and obesity in childhood and adulthood. The aim of this study wa...

Lack of association between high serum thyroid-stimulating hormone level and risk of papillary thyroid microcarcinomas.

BACKGROUND High serum thyroid-stimulating hormone (TSH) is associated with thyroid carcinoma in patients with thyroid nodules. However, previous studies suggests that TSH is not involved in the pathogenesis of small thyroid carcinomas. We performed this study to evaluate serum TSH as a malignancy predictor in the assessment of small thyroid nodules. METHODS We retrospectively analyzed 3791 pa...

Maternal-Fetal Thyroid Interactions

Maternal and fetal thyroid function.

Conception is followed by a series of hormonal and metabolic changes that involve most maternal endocrine systems. With regard to thyroid metabolism, these include an increase in serum thyroxine-binding globulin and thyroid hormone concentrations, increased renal clearance of iodine, and increased production and turnover of thyroxine (T). Fetal and maternal thyroid physiology differ, but the sy...

A Link Between Maternal Thyroid Hormone and Sexual Orientation?

The search for the cause of gender nonconformity and homosexuality has been extensive. Researchers have proposed a variety of different causes, from early childhood experiences to birth order to hormonal influences,1-3 but have yet to pinpoint a reliable explanation of our sexual orientation. Prior research into biological influences of sexual orientation has focused on adult hormone levels,3 a...
