Description
Summary:	The investigation was conducted to document the effect of alcohol on the morphology of thyroid gland of male rat offspring whose dams consumed alcohol during pregnancy and/or lactation. Seventy-five female rats divided into three groups, 1, 2, and 3, of 25 each and their offspring were used. Group 1 served as control (C), group 2 was exposed to alcohol during pregnancy and lactation (APL) while group 3 was exposed to alcohol during lactation only (AL). At day 35 and 49 postpartum 5 male rat offspring were randomly selected from the three groups and sacrificed. After the sacrifice, the thyroids were dissected out and their absolute and relative weights determined. Thereafter, the thyroid tissues were prepared for routine histological examination. The results of the investigation showed significant reduction (P<0.05) in the weights of the thyroid and thyroid follicles. There was also disorganization and desquamation of follicular cells. Our findings suggest that alcohol intake during pregnancy and/or lactation could be injurious to the thyroid glands of the offspring.
