Question:
During arousal how much do your breast enlarge?

Answer:
by Annette Owens:
(05/15/2004)
In 1966 Masters & Johnson raised the possibility that erection of the nipples in both men and women and enlargements of the breasts in women may be specifically sexual responses during arousal (Masters WH & Johnson VE, 1966, Human sexual response; Churchhill Livingstone, London). To my knowledge this hypothesis has yet to be proven. I am not aware of any research addressing your specific question. Therefore, unfortunately I am unable to give you a precise answer. Bodily changes during arousal (in genital as well as in other areas of the body) are to a large part related to cardiovascular changes (raised blood pressure, altered heart rate, skin temperature and skin color changes.) I assume that increased blood flow in the breasts could account for a slight enlargement of the breast tissue. Other physiological changes during sexual arousal include respiratory changes and pupillary dilation. Obviously, all these changes can be caused by a number of other types of arousing but non-sexual stimuli. Sincerely, Annette Fuglsang Owens, MD PhD
