As part of the path to a certain qualification and again for renewal at intervals, I once went for a specialised medical examination which took a good while. During the time involved the licensed medical practitioner (the only one over a large area) and I found ourselves in conversation which ranged over several topics. At one point he made the remark that once/as many women become older they, those who have had children in particular, begin to find that their innards start to fall out. I was in my early 30s and didn't understand what he meant and simply said that this sounded alarming. I can't quite remember if he said anything further. More recently as the women I know are now older it is quite evident what he meant and some of these women have had operations to stitch everything back up, with varying degrees of success. The problem primarily arises through human posture development (i.e. standing upright) outstripping development of the infrastructure called the pelvic floor. Gravity causes everything that has been stretched, pushed, squashed and generally distressed over time to sag onto this structure which has an opening without a sphincter on it. The result is that, in all of this pile-up, the bladder comes under pressure and at times even oozing/bulging out of certain tissue occurs. Part of the resulting sensation is a much heightened urge to empty the bladder, again and again as the kidneys constantly process/produce urine.
Men do not go through the same trauma of the internal physiology so the incidence is much lower than for women. Addressing the advertising for a product or service to deal with this problem more to women than men strikes me as very understandable - not quite as obvious as with the advertising of menstrual items but akin nevertheless.
That is my understanding, no doubt Sqad will provide a much more erudite treatise (I bow).
