You may call it a 'booby' trap but woman's breasts are really a man's first fixation, a new study has revealed.
An international team, led by University of Wellington in New Zealand, has found that virtually half of blokes first look at a woman's breast — and, men glance at them for longer than any other body part, the Daily Mail reported.
A third of the so-called “first fixations” are on the waist and hips, while fewer than 20 per cent look at the face, the study has found.
Though it's claimed the reason might be evolutionary, as women with larger chests and slim waists have higher levels of the female hormone oestrogen, indicating greater fertility, researchers say there may be a more prosaic explanation.
“Men may be looking more often at the breasts because they are simply aesthetically pleasing, regardless of the size," they were quoted as saying.
In their study, the researchers presented a group of subjects with six images of the same woman, digitally altered to increase or decrease the size of her bust, waist and hips.
They recorded which areas men looked at first, the number of times they looked, and how long their gaze lasted, using both cameras and mirrors to measure tiny eye movements.
"Eighty per cent of first fixations were on the breasts and midriff. Men spent consistently more time looking at the breasts and also made significantly more fixations upon them than other regions," the researchers said.
