Thyroid-Stimulating Hormone Levels in Pregnancy and Their Association With Depression, Anxiety, and Sexual Function

This prospective, single-center, observational cross-sectional study aims to evaluate the relationship between thyroid-stimulating hormone (TSH) levels and psychological as well as sexual health outcomes during pregnancy. Pregnant individuals will undergo psychometric assessment using the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), the Arizona Sexual Experience Scale (ASEX), and the YKK-13 Quality of Life Scale. The study will investigate whether maternal TSH levels are associated with depression, anxiety, sexual function, and overall quality of life scores. Eligible participants will be pregnant women aged 18-45 years with a singleton pregnancy of at least 6 weeks, who are literate and have provided informed consent. Individuals with a prior psychiatric history, multiple gestation, or existing systemic or endocrine diseases will be excluded. The primary endpoint of the study is to determine the association between TSH levels and psychometric scale scores during pregnancy.
