A third cause of natural barrenness, is the letting virgins blood in the arm before their natural courses are come down, which is usually in the fourteenth and fifteenth year of their age; sometimes, perhaps before the thirteenth, but never before the twelfth. And because usually, they are out of order, and indisposed before their purgations come down, their parents run to the doctor to know what is the matter; and he, if not skilled, will naturally prescribe opening a vein in the arm, thinking fullness of blood the cause; and thus she seems recovered for the present: and when the young virgin happens to be in the same disorder, the mother applies again to the surgeon, who uses the same remedy; and by these means the blood is so diverted from its proper channel, that it comes not down the womb as usual, and so the womb dries up, and she is for ever barren. To prevent this, let no virgin blood in the arm before her courses come down well; for that will bring the blood downwards, and by that means provoke the menstrua to come down.
Another cause of natural barrenness, is debility in copulation. If persons perform not that act with all the bent and ardour that nature requires, they may as well let it alone; for frigidity and coldness never produces conception. Of the cure of this we will speak by and by, after I have spoken of accidental barrenness, which is occasioned by some morbific matter or infirmity in the body, either of the man or of the woman, which being removed they become fruitful. And since, as I have before noted, the first and great law of creation, was to increase and multiply, and barrenness is in direct opposition to that law, and frustrates the end of our creation, and often causes man and wife to have hard thoughts one of another, I shall here, for the satisfaction of well meaning people, set down the signs and causes of insufficiency both in men and women; premising first that when people have no children, they must not presently blame either party, for neither may be in fault.
SECT. II.—Signs and Causes of Insufficiency in Men.
One cause may be in some viciousness of the yard, as if the same be crooked, or any ligaments thereof distorted and broken, whereby the ways
and passages, through which the seed should flow, come to be stopped or vitiated.
Another cause may be, too much weakness of the yard, and tenderness thereof, so that it is not strong enough erected to inject seed into the womb; for the strength and stiffness of the yard very much conduces to conception, by reason of the forcible injection of the seed.
Also, if the stones have received any hurt, so that they cannot exercise the proper gift in producing seed, or if they be oppressed with an inflammation, tumour, wound or ulcer, or drawn up within the belly, and not appearing outwardly.
Also, a man may be barren by reason of the defect of seed, as first, if he cast forth no seed at all, or less in substance than is needful. Or, secondly, if the seed be vicious, or unfit for generation; as on the one side, it happens in bodies that are gross and fat, the matter of it being defective; and on the other side, too much leanness, or continual wasting or consumption of the body, destroys seed; nature turning all the matter and substance thereof into the nutriment of the body.
Too frequent copulation is also one great cause of barrenness in men; for it attracteth the seminal moisture from the stones, before it is sufficiently prepared and concocted. So if any
one, by daily copulation, do exhaust and draw out all their moisture of the seed, then do the stones draw the moist humours from the superior veins unto themselves; and so, having but a little blood in them, they are forced of necessity to cast it out raw and unconcocted, and thus the stones are violently deprived of the moisture of their veins, and the superior veins, and all the other parts of the body, of their vital spirits; therefore it is no wonder that those who use immoderate copulation are very weak in their bodies, seeing their whole body is deprived of the best and purest blood, and of the spirit, insomuch that many who have been too much addicted to that pleasure, have killed themselves in the very act.
