What is the testicular artery a branch of?
abdominal aorta
The testicular artery, a branch of the abdominal aorta, descends through the inguinal ring into the cranial border of the spermatic cord in a tortuous manner and divides near the testis into several branches to supply the testis and epididymis.
What is the function of the testicular arteries?
It arises in the abdomen and reaches the scrotum by traversing the spermatic cord. The main function of the testicular arteries is to provide the blood supply to the testes, along with the arteries to ductus deferens and cremasteric arteries.
What is a testis in biology?
testis, plural testes, also called testicle, in animals, the organ that produces sperm, the male reproductive cell, and androgens, the male hormones. In humans the testes occur as a pair of oval-shaped organs.
What is the cremasteric artery a branch of?
inferior epigastric artery
The cremasteric artery is a small branch of the inferior epigastric artery that enters the deep inguinal ring of the inguinal canal and supplies the layers of the spermatic cord and also the skin of the scrotum, including the cremaster muscle.
What is the function of tunica albuginea?
The tunica albuginea (TA) envelops the penile erectile bodies and is composed of organized fibrillar collagen interlaced with elastin fibers, which allow tunica expansion. It protects erectile tissue, promotes penile rigidity and length, and participates in the veno-occlusive mechanism.
How does varicocele occur?
Your spermatic cord carries blood to and from your testicles. It’s not certain what causes varicoceles. However, many experts believe a varicocele forms when the valves inside the veins in the cord prevent your blood from flowing properly. The resulting backup causes the veins to widen (dilate).
Why do testes receive blood supply from testicular artery?
In addition to providing oxygen, nutrients and removing waste from the area, the rich vascular supply of the testes has other functions. This is because the organs have temperature specific functionality, while also functioning as endocrine glands as well as reproductive organs.
Why arteries do not have valves?
Arteries carry oxygenated blood away from the heart. (Arteries don’t require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.
Are testes glands?
The testes are two oval-shaped male reproductive glands that produce sperm and the hormone testosterone.
What structures do the testicular arteries cross?
Each testicular artery crosses in front of the respective genitofemoral nerve and ureter to pass the deep inguinal ring and enter the spermatic cords. Along with the other contents of the cord, they enter the scrotum via the inguinal canal.
Is testicular artery end 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 testis. It is a paired artery, with one for each of the testes….

What does the testicular artery supply?
testicular artery. In males, a long slender branch of the abdominal aorta arising below the renal artery; it supplies blood to the testes, epididymis, cremasteric muscles, and lower ureters. Synonym: spermatic artery; internal spermatic artery; See: aorta (Branches of aorta)for illus.
Where does the blood supply to the testis come from?
However, the testicular artery forms a network of connections with the internal iliac artery, which supplies the vas deferens, so that the blood supply to the testis effectively has two origins. Venous drainage is into the inferior vena cava on the right and the renal vein on the left.
What artery supplies the epididymis with the testis?
Testicular artery. Two or three of these accompany the ductus deferens, and supply the epididymis, anastomosing with the artery of the ductus deferens; others pierce the back part of the tunica albuginea, and supply the substance of the testis .
What is the difference between the testis and ovarian artery?
Because the testis is found in a different location than that of its female equivalent, it has a different course than the ovarian artery. They are two slender vessels of considerable length, and arise from the front of the aorta a little below the renal arteries .
