The fourth cause is often merely dislike towards the husband. The last two causes, weakness of the husband and dislike towards him, are unfortunately very frequent, and a wife who was frigid with one husband may show herself very passionate on marrying another man.
The fifth cause is fear of pregnancy.
The above are the five principal causes. Other causes may be disease of the uterus, laceration of the cervix, inflammation of the ovaries, vaginismus, disease of the thyroid gland, etc.
It is an unfortunate fact that women who were frigid up to the age of forty or so may become very passionate after that age.
As to the treatment of frigidity, little or nothing can be done for frigidity that is congenital. Most of the other kinds of frigidity, however, can be cured.
