Abstract
Context: A cross-sectional study was designed to find out the difference in weight of the thyroid gland of Bangladeshi people in relation to age and sex and to compare with previous local and foreign studies. Materials & Methods: The present study was performed on 60 post mortem human thyroid gland (39 of male and 21 of female) collected from unclaimed dead bodies which were in the morgue under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age-groups including Group A (10-20 years), Group B (21-50 years) & Group C (>50 years) and the weight of the thyroid glands were measured and recorded. Results: The mean weight of the thyroid gland in male was 15.14 gm, 19.20 gm and 14.64 gm and in female was 16.02 gm, 19.03 gm and 14.67 gm in group A, B and C respectively. The mean weight of the thyroid gland was 15.48 gm in group A, 19.15 gm in group B and 14.65 gm in group C. There was no difference in mean weight of the thyroid gland between male and female. The difference in mean weight of the thyroid gland between group A & group B and group B & group C were found statistically significant. The weight of the gland was found to increase from early childhood and puberty up to 50 years of age and then decrease. Key words: Thyroid gland; Weight of thyroid gland.

Highlights
The thyroid gland is a very important endocrine gland, which is concerned with rate of metabolism, blood calcium level, and affects on growth and development in mammals[1]
There is a limitation of published work on morphological variations of the thyroid gland in different age groups of Bangladeshi people
Results of the morphological study of the thyroid in Bangladeshi people are most likely to differ from those of with adequate iodine intake[5], as iodine is very essential for the biological activity of the thyroid gland[6]
Summary
The thyroid gland is a very important endocrine gland, which is concerned with rate of metabolism, blood calcium level, and affects on growth and development in mammals[1]. There is a limitation of published work on morphological variations of the thyroid gland in different age groups of Bangladeshi people. Results of the morphological study of the thyroid in Bangladeshi people are most likely to differ from those of with adequate iodine intake[5], as iodine is very essential for the biological activity of the thyroid gland[6]. It has been observed by various researchers that the dimensions of different organs in Bangladeshi population have got variations from those of the western population[5]. All the samples were collected within 24-36 hours of death without any sign of putrefaction, from medicolegal cases excluding hanging, poisoning, any cutting or crushing injury to
