Smaller 2D:4D Digit Ratio in Male Rats Linked to Stronger Sexual Drive and Preference Towards Females (IMAGE)
Caption
This illustration, inspired by the visual storytelling style of traditional Japanese ukiyo-e, depicts how fetal androgen exposure may influence both the 2D:4D digit ratio and sexual behavioral tendencies, using the living environment of rats as a metaphorical stage. At the rear of the scene, a shower booth symbolizes prenatal hormone exposure, while the shadow of the tenugui towel represents varying levels of androgen exposure. At the center, the measurement of the 2D length is depicted, while on either side, olfactory preference, such as interest in bedding carrying the scent of females, and general behavioral activity are represented visually.
