Theses de suppressis mensibus

XXX.
Now, by a defect of the material, the menses are suppressed either because there is none, or because it is present but does not descend to the uterus, or it descends but is not purged.

XXXI.
It is absent when, by a defect of the concoctive faculty the body's power to digest or process humors however it may be weakened, the superfluous blood is not generated.

XXXII.
It is present, indeed, but does not descend to the uterus, being either consumed, turned away, or retained.

XXXIII.
It is consumed by heat, whether natural or increased beyond nature, as in diseases that are both acute and chronic; but also in vehement disturbances of the mind, where the blood that was present is seized by natural necessity for nourishment, especially when the nourishment provided from outside is either none or very little.

XXXIIII.
Likewise, it cannot descend to the uterus because it is turned away, as it is evacuated through other parts under its own form, such as through the spitting of blood, vomiting, a flow through the nostrils, hemorrhoids, or a wound; sometimes under a foreign form, such as sweat, excrement, vomit, or pustules blooming on the skin.

XXXV.
There are times when it is retained in the middle of the way of descent to the uterus, and then it exudes into the habit of the whole body, but short of expulsion.
