Utafiti uliofanywa na Prof. Colin Hendrie wa chuo kikuu cha Leeds, umeonyesha kuwa wanawake wenye hips upana wa zaidi ya (14.2in (36cm)) ndio wenye wapenzi wengi zaidi na vilevile hushiriki mapenzi ya kumalizana hapo hapo yaani One-night stand.
A new study has revealed that women with wide hips are more likely to have one-night stands and more sexual partners in general.
This is essentially because they do indeed find childbirth less traumatic, the authors suggest.
The researchers define wide hips as those wider than 14.2 inches (36 centimetres) and small hips as those under 12.2 inches (31 centimetres wide).
This is measured by the distance between the upper outer edges of the iliac crest bones of the pelvis - the widest part of the hip bone.
The measurement is that across, not the circumference.
The 148 women in the study - aged between 18 and 26 - also had their hip circumference at the widest point measured and their waist circumference at its narrowest point.
All the women had at least one sexual partner previously. They also completed a questionnaire about their sexual histories, including the age at which they lost their virginity, the number of sexual
partners they'd had, and information about emotionally significant sexual relationships they had had.
