Blood supply and lymphatic drainage of the testes and scrotum are distinct: The paired testicular arteries arise directly from the abdominal aorta and descend through the inguinal canal , while the scrotum and the rest of the external genitalia is supplied by the internal pudendal artery (a branch of the internal iliac artery ).
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 ...

It accompanies the ductus deferens into the testis, where it anastomoses with the testicular artery; in this way it also supplies blood to the testis and epididymis. A small branch also supplies the ureter .
The spermatic cord is sensitive to torsion, in which the testicle rotates within its sac and blocks its own blood supply. Testicular torsion may result in irreversible damage to the testicle within hours. A collection of serous fluid in the spermatic cord is named 'funiculocele'.
The vas deferens consists of an external adventitial sheath containing blood vessels and nerves, a muscular middle layer composed of three layers of smooth muscle (with a circular muscle layer interposed between two longitudinal muscle layers), and an internal mucosal lining consisting of pseudostratified columnar epithelium (which bears the ...
Without an adequate insulin supply, glucose can’t enter your cells, meaning more stays in your blood. ... An A1C test also measures your blood sugar levels, but as a cumulative average over the ...
It is also responsible for carrying the blood supply of the penile skin, a longitudinally-coursing anastomotic network of vessels that arise from the external pudendal vessels. [1] In the scrotum, the dartos fascia acts to regulate the temperature of the testicles, which promotes spermatogenesis. It does this by expanding or contracting to ...
