An ovotestis is a gonad with both testicular and ovarian aspects. [1] [2] In humans, ovotestes are an infrequent anatomical variation associated with gonadal dysgenesis. [3]The only mammals where ovotestes are not characteristic of an infrequent variation are moles, wherein females possess ovotestes along with a masculinized clitoris.
The testicular artery (the male gonadal artery, also called the internal spermatic arteries in older texts) is a branch of the abdominal aorta that supplies blood to the testicle. It is a paired artery, with one for each of the testicles. It is the male equivalent of the ovarian artery. Because the testis is found in a different location than ...
testes, ovary: Leydig cells: AR: libido, Anabolic: growth of muscle mass and strength, increased bone density, growth and strength, Virilizing: maturation of sex organs, formation of scrotum, deepening of voice, growth of beard and axillary hair. Dehydroepiandrosterone: androgen: DHEA: testes, ovary, kidney: Zona fasciculata and Zona ...
The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. Some hermaphroditic animals (and some humans — see Ovotesticular syndrome) have a type of gonad called an ovotestis.
These are different arteries in women (ovarian vein) and men (testicular vein), but share the same embryological origin. [ 1 ] The termination of the two gonadal veins in an individual is usually asymmetrical, with the left one draining into the left renal vein, and the right one draining into the inferior vena cava.

Testis in the place of its original formation; t', together with the dotted lines above, indicates the direction in which the testis and epididymis descend from the abdomen into the scrotum. Skene's glands a.k.a. paraurethral gland: pr. Prostate: u. Uterus.
Since the scrotum, where the testes is present, is situated outside the body cavity, it provides a temperature about 3 °C below normal body temperature. In females, gametogenesis is known as oogenesis; this occurs in the ovarian follicles of the ovaries. This process does not produce mature ovum until puberty.
The part of the gubernaculum between the ovary and the uterus ultimately becomes the proper ovarian ligament, while the part between the uterus and the labium majus forms the round ligament of the uterus. A pouch of peritoneum analogous to the vaginal process in the male accompanies it along the inguinal canal: it is called the canal of Nuck.
