Individuals with one testicle are called monorchids, and may be divided into three varieties:--(1) A solitary testicle divided in the middle by a deep fissure, the two lobes being each provided with a spermatic cord on the same side as the lobe.
(2) Testicles of the same origin, but with coalescence more general.
(3) A single testicle and two cords.
Gruber of St. Petersburg held a postmortem on a man in January, 1867, in whom the right half of the scrotum, the right testicle, epididymis, and the scrotal and inguinal parts of the right vas deferens were absent. Gruber examined the literature for thirty years up to the time of his report, and found 30 recorded postmortem examinations in which there was absence of the testicle, and in eight of these both testicles were missing. As a rule, natural eunuchs have feeble bodies, are mentally dull, and live only a short time. The penis is ordinarily defective and there is sometimes another associate malformation. They are not always disinclined toward the opposite ***.
Polyorchids are persons who have more than two testicles. For a long time the abnormality was not believed to exist, and some of the observers denied the proof by postmortem examination of any of the cases so diagnosed, but there is at present no doubt of the fact,--three, four, and five testicles having been found at autopsies. Russell, one of the older writers on the testicle, mentions a monk who was a triorchid, and was so salacious that his indomitable passion prevented him from keeping his vows of chastity. The amorous propensities and generative faculties of polyorchids have always been supposed greater than ordinary.
Russell reports another case of a man with a similar peculiarity, who was prescribed a concubine as a reasonable allowance to a man thus endowed.
Morgagni and Meckel say that they never discovered a third testicle in dissections of reputed triorchids, and though Haller has collected records of a great number of triorchids, he has never been able to verify the presence of the third testicle on dissection. Some authors, including Haller, have demonstrated heredity in examples of polyorchism. There is an old instance in which two testicles, one above the other, were found on the right side and one on the left. Macann describes a recruit of twenty, whose scrotum seemed to be much larger on the right than on the left side, although it was not pendulous. On dissection a right and left testicle were found in their normal positions, but situated on the right side between the groin and the normal testicle was a supernumerary organ, not in contact, and having a separate and short cord. Prankard also describes a man with three testicles. Three cases of triorchidi** were found in recruits in the British Army. Lane reports a supernumerary testis found in the right half of the scrotum of a boy of fifteen. In a necropsy held on a man killed in battle, Hohlberg discovered three fully developed testicles, two on the right side placed one above the other. The London Medical Record of 1884 quotes Jdanoff of St.
Petersburg in mentioning a soldier of twenty-one who had a supernumerary testicle erroneously diagnosed as inguinal hernia.
Quoted by the same reference, Bulatoff mentions a soldier who had a third testicle, which diagnosis was confirmed by several of his confreres. They recommended dismissal of the man from the service, as the third testicle, usually resting in some portion of the inguinal canal, caused extra exposure to traumatic influence.
Venette gives an instance of four testicles, and Scharff, in the Ephemerides, mentions five; Blasius mentions more than three testicles, and, without citing proof, Buffon admits the possibility of such occurrence and adds that such men are generally more vigorous.
Russell mentions four, five, and even six testicles in one individual; all were not verified on dissection. He cites an instance of six testicles four of which were of usual size and two smaller than ordinary.
Baillie, the Ephemerides, and Schurig mention fusion of the testicles, or synorchidism, somewhat after the manner of the normal disposition of the batrachians and also the kangaroos, in the former of which the fusion is abdominal and in the latter scrotal. Kerckring has a description of an individual in whom the scrotum was absent.
