We must, then, first of all inquire whether all these particulars are well ordered; and, next, we must learn the position of the body of the uterus; for it ought to be straight; and if it is not so, the seminal fluid can never reach it. And it is evident that women project their semen forwards, from what happens when they have lascivious dreams; for this part of them then requires attention, being moistened as though they had sexual intercourse, for they also project into the place where the semen of the male is emitted, and not into the uterus; and when projected to this place, the semen is drawn into the uterus by inhalation, as the mucus is drawn into the nose. For this reason they become pregnant in every position; for the seminal fluid both in men and women is always projected forwards; but if it were projected into the female she would not always conceive after copulation. 2. But if the uterus is not straight, but inclined to the hips, the loins, or the hypogastric region, it is impossible to conceive, for the before-mentioned reason, that the uterus cannot take up the seminal fluid. If this deformity is great, either naturally or from disease, the disorder is incurable. If there is a rupture, either by nature or arising from the disease, which contracts the parts with inflammation, the disorder will take a different turn from this. But in order that women may become pregnant, it is necessary, as it was said, that the mouth of the uterus should be straight and, moreover, should be well opened. By this I mean that when the menstrual discharge commences, the os uteri should, on contact, appear softer than before, though not distinctly expanded. But if this is the case, let the first appearance be white. 3. But when the appearances are more the colour of flesh, the uterus will be evidently relaxed without pain when it is touched, and the os uteri is neither dull nor different from itself; and when the discharge ceases, let the aperture be very open and dry, but not hard, for a day and a half or two days; for this shows that the uterus is in a healthy state, and fit to perform its functions. If the os uteri is not immediately relaxed, but appears soft, it shows that both the uterus and the rest of the body are relaxed, and the uterus does not prevent, but first discharges the secretion from the os uteri. And when the rest of the body has discharged a great deal, and the os uteri becomes relaxed, it is a sign of a healthy condition.
