Two testicles and two ovaries.—Various in stances have now been published in which this sexual duplicity has been supposed to exist among cattle and other domestic quadrupeds, as well as in the human subject.
One of the free-martins* described by Mr. Hunter comes under this variety. In the case referred to, in the situation of the ovaries " were placed," to use IN] r. Hunter's words, " both the ovaria and testicles,"—or, as Sir Everard Home, in alluding to this case, more justly expresses it, " an appearance like both testicles and ovaria was met with close toge ther."-f The two contiguous bodies were nearly of the same size, being each about as large as a small nutmeg. There were no Fallopian tubes running to the ovaries, but a horn of an imperfect uterus passed on to them on each side along the broad ligament. Pervious vasa deferentia were found ; they did not, however, reach up completely to the testicle on either side, or form epididymes. The vesiculre semi nales were present, and much smaller than in the perfect bull. The external parts appear to have been those of the cow, but smaller than natural. The vagina passed on, as in the cow, to the opening of the urethra, and, after having received it and the orifices of the seminal ducts, it began to contract into a small canal, which ran upwards through the uterus to the place of division of that organ into its two horns.
Velpeau,t in his work on Midwifery, men tions that in an embryo calf, he had " found reunited the testicles and ovaries, the vasa deferentia, and uterus." In an hermaphroditic foal-ass, Mr. Ilunter5 found both what he considered to be two ovaries placed in the natural situation of these bodies, and two testicles lying in the inguinal rings in a process or theca of peritonarum similar to the tunica vaginalis communis in the male ass. No vasa deferentia or Fallopian tubes could be detected ; but there was a double-horned uterus present, and from its broad ligaments, (to the edges of which the cornua uteri and ovaries were attached,) there passed down on either side into the inguinal rings a part similar to the round ligament in the female. The
horns and fundus of the uterus were pervious ; but its body and cervix, and the canal of the vagina from above the opening of the urethra into it, were imperforate. The external parts were similar to those of the female ass; but the clitoris, which was placed within the entrance of the vagina, was much larger than that of a perfectly formed female ; it measured about five inches. The animal had two nipples.
Scriba has given an accountH of an hermaphroditic sheep, in which two large testicles are stated to have been found in the scrotum, at the same time that there existed, in their nor mal situation, two moderately sized ovaries, and a small uterus furnished with two appa rently closed Fallopian tubes. The external sexual parts appear to have been those of a malformed male, the penis being short and im pervious, the scrotum divided, and the urethra opening into a contracted perinatal fissure re sembling the female vulva. This animal had often attempted connection with the female sheep.
Borkhausen) has described a very similar case in the same species of animal. Each half of the divided scrotum contained a testicle which was regularly formed, but greater in size than usual, and furnished with a large sperma tic artery. The pelvis contained a normal uterus, which was smaller, however, than na tural ; it was provided with its usual ligaments. The Fallopian tubes were present but imper forate, and the two ovaries were full of vesicles and inclosed in a strong membrane. The vagina was natural and opened as in the female. Behind the divided scrotum the rudiment of an udder with four teats (instead of two) was situated. The male penis was also present, but diminutive and short ; its erectores muscles were small, and the prostate gland indistinct. The urethra was single as it left the bladder, but it afterwards divided into two canals, the wider of which opened into the female vagina and vulva, and the narrower ran through the male penis. The urine passed in a full stream through the former canal, and only by drops through the latter. The animal is alleged to have attempted coition in both ways.
