Morphologically sexual dimorphism is well characterised in Homo sapiens. This also reflects in many of their physiological activities too; among those, sleep is one. Sleep differences between human male and female is a comparatively new area and drawn attention of the scientists recently. In this short review, we have taken two aspects namely, endocrinological, which is well established factor and the other one which is less defined, the microbial content. Recent researches have shown the michrobial contents are also regulated by hormonal milieu and therefore, directly or indirectly hormones play the role in sleep sexual dimorphism.
