Summary
Maternal thyroid health is vital for fetal neurodevelopment. Exposure to endocrine disrupting chemicals (EDCs) may disrupt thyroid hormones, potentially harming fetal development, necessitating further research.
Area of Science:
- Endocrinology
- Environmental Health
- Developmental Biology
Background:
- Maternal euthyroidism is essential for fetal development, particularly neurodevelopment.
- Hypothyroidism affects up to 3.5% of pregnant women.
- Widespread industrial use of endocrine disrupting chemicals (EDCs) leads to human exposure.
Purpose of the Study:
- To examine the impact of EDCs on maternal thyroid homeostasis and fetal development.
- To highlight the potential risks of combined EDC exposure on thyroid hormone regulation.
- To inform the ongoing debate regarding EDC usage.
Main Methods:
- Literature review focusing on EDCs with suspected thyroid-disrupting properties.
- Analysis of mechanisms by which EDCs may interfere with thyroid hormone homeostasis.
- Examination of existing human and animal studies on EDC effects.
Main Results:
- EDCs can affect thyroid hormone homeostasis through various pathways.
- While individual EDC effects may appear minor, cumulative impacts can be significant.
- Limited human studies exist, underscoring a knowledge gap.
Conclusions:
- EDCs pose a potential risk to maternal thyroid function and fetal neurodevelopment.
- Further research, especially human studies, is crucial to understand the full impact of EDCs.
- This knowledge is vital for public health policies concerning chemical safety.

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:18Functions of Thyroid Hormones
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

01:20Synthesis and Regulation of Thyroid Hormones
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

01:36Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
01:24Gonadal and Placental Hormones
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
