Prenatal and Postnatal Exposure to White and Black Colors Increase Serum Estrogen Level in Female Rat Offspring

Abstract

Background.Prenatal and postnatal stimulations have been revealed to have long-term effects on rat offspring various reproductive and behavioral reactions.The current study was designed to assay the impact of prenatal and postnatal exposure to different colors on variations of serum estrogen levels in female adult offspring. Four groups of pregnant female Wistar rats (seven rats in each) were enrolled in this study. The pregnant rats were placed in color chambers including green, blue, black and white (control). After delivery, female offspring’s were kept in color chambers until age 8-9 weeks, and then estrogen concentration in serum of female adult offspring’s were measured using the ELISA Kit. Our study result revealed that serum estrogen level increased in female adult offspringwho were prenatally and postnatally exposed to white and black colors compared to female adult offspring’s who were exposed to green and blue colors. Exposure to blue color significantly decreased serum estrogen level in female adult offspring. These findings demonstrated serious changes of estrogen in female offspring due to prenatal and postnatal exposure to different colors which can be translated as estrogen variables. We can document that prenatal and postnatal stimulation can lead to estrogen alterations in female offspring and such changes can be made by colors.
