The trophicity of women's urogenital tissues depends on the hormone level and on the quality of the vaginal flora. Stresses of these mucous membranes, seemingly minor, give rise to complaints of a perceived perineal discomfort, which is disproportionate to the causes. Population in Occident has access to the best medical care and hygiene conditions ever. Yet, expenditures on treatment of these minor disorders are unwarranted. Cystalgia leads to a large number of consultations to general practitioner, gynaecologist and urologist. The aging of our societies is another reason. While life expectancy was 51 in 19th century, it is now 83. Women will now live a third of their life after menopause'. Complaints due to these hormonal withdrawal symptoms need to be heard as they are leading to specific psychological behaviours, which are disconcerting for the clinician. Patients will strive by all means to obtain treatments which are often inappropriate and which sometimes entails the risk of evolving to a chronicity of the pains.
