Why women do not get micturition syncope?--a hypothesis.
In the present communication, the author hypothesises on the rarity of Indian women to suffer from micturition syncope while this is fairly common amongst men of all ages. Most Indian women adopt a squatting posture during micturition in contrast to men who prefer to stand. Squatting induced increased adrenergic drive and the resultant rise of blood pressure seems to negate the parasympathetic overactivity that results from bladder evacuation causing micturition syncope. Significant venous pooling in legs is also prevented by adopting a squatting posture and using a commode seat.
