The womb is joined to its neck in the lower part of the Hypogastrium where the hips are the widest and broadest, as they are greater and broader there than those of men, and it is placed between the bladder and the straight gut, which keeps it from swaying, and yet gives it freedom to stretch and dilate, and again to contract, as nature requires.  Its shape is somewhat round and not unlike a gourd, growing smaller and more acute towards one end, being knit together by its own ligaments; its neck likewise is joined by its own substance and by certain membranes that fasten into the os sacrum and the share-bone.  Its size varies much in different women, and the difference is especially great between those who have borne children and those who have had none.  Its substance exceeds a thumb’s breadth in thickness, and so far from decreasing conception, it rather increases; and in order to strengthen it it is interwoven with fibres which cross it from side to side, some of which are straight and some winding, and its proper vessels are veins, arteries and nerves.  Amongst these there are two small veins which pass into the womb from the spermatic vessels, and two larger ones from the neck:  the mouth of these veins pierces as far as the inward cavity.

The womb has two arteries on both sides of the spermatic vessels and the hypogastric, which accompany the veins; and besides these, there are several little nerves in the form of a net, which extend throughout it, from the bottom of the pudenda; their chief function is sensibility and pleasure, as they move in sympathy between the head and the womb.

It may be further noted that the womb is occasionally moveable by means of the two ligaments that hang on either side of it, and often rises and falls.  The neck of the womb is extremely sensitive, so that if it be at any time out of order through over fatness, moisture or relaxation, it thereby becomes subject to barrenness.  With pregnant women, a glutinous matter is often found at the entrance to the womb so as to facilitate the birth; for at the time of delivery, the mouth of the womb is opened as wide as the size of the child requires, and dilates equally from top to bottom.

The spermatic vessels in women, consist of two veins and two arteries, which differ from those of men only in size and the manner of their insertion; for the number of veins and arteries is the same as in men, the right vein issuing from the trunk of the hollow vein descending and besides them there are two arteries, which flow from the aorta.
