Suppose, now, the case is that of a man of fifty who is physically run down, married, and anxious to be the father of a child. In such a case, if the man is physically sound, Dr. Brinkley will do one of two things. After the transplantation of the new glands he will either ligate one side permanently, and allow one testis to carry on the work of rejuvenation while the other can be used for procreation, or he will ligate both sides and say to the man, "I am tying off both testes because you will need to rebuild for at least one year before you should think of becoming a father. But I am ligating with linen thread, which does not dissolve, and if you come back to me in one year from now I will remove the ligatures, one or both, and you will then be able to procreate." This is reasonable and wise talk, and the man makes no objection. When the year of probation, as you might call it, has expired, the man returns to the hospital, the ligature is removed, and he goes home in a couple of days. These things are not fairy-tales, but solid facts, amazing as they sound to you. There are five goat-gland babies today among Dr. Brinkley's patients that he knows of, four boys and one girl. There are probably many more of whom he has heard nothing, for patients have a way of moving out of touch after awhile. CHAPTER III THE PRACTICE. WOMEN At Dr. Brinkley's hospital, a beautifully appointed private residence, it is a comfort to women patients to have the doctor's wife, herself a competent surgeon if necessary, at hand during the actual operation. Mrs. Brinkley administers the local anesthetic, or the general anesthetic, if that is called for, as it sometimes is. While the bulk of the operations performed on both men and women are gland-transplantations, a diseased condition of tubes and ovaries has sometimes made a laporotomy necessary, and many major operations have been successfully performed in the white-enameled operating room. At such times a woman clings to the presence of a woman, and Mrs. Brinkley's kind and pleasant manner is usually sufficient to banish all nervousness from the woman patient.
