The effects of maternal thyroid hormone function on early pregnancy

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Reproductive Medicine

Background:

• The role of nonovert thyroid disease in pregnancy outcomes is debated.
• Universal thyroid screening in pregnancy lacks definitive evidence for improved outcomes.
• In vitro fertilization (IVF) advancements prompt investigation into their impact on thyroid function.

Purpose of the Study:

• To review current literature on thyroid disease in pregnancy.
• To evaluate the impact of nonovert thyroid disease on pregnancy outcomes.
• To examine the role of thyroid screening and IVF on thyroid function.

Main Methods:

• Literature review of recent studies on thyroid disease in pregnancy.
• Analysis of guidelines from multiple societies regarding thyroid screening.
• Examination of research on the economic and prevalence aspects of screening.
• Review of studies on IVF and its effect on thyroid function.

Main Results:

• Current guidelines do not universally advocate for thyroid screening in pregnancy.
• Screening shows economic and prevalence benefits, but evidence for improved outcomes is inconsistent.
• Treatment of nonovert thyroid disorders has not consistently improved maternal and fetal outcomes.
• Monitoring and treatment of thyroid dysfunction are recommended for women undergoing IVF.

Conclusions:

• Further research is needed to determine if treating nonovert thyroid disease in pregnancy affects outcomes.
• Evidence on treatment efficacy will likely shape the debate on universal thyroid screening during pregnancy.
