The cremasteric artery (external spermatic artery) is a branch of the inferior epigastric artery which accompanies the spermatic cord, and supplies the cremaster muscle and other coverings of the cord, anastomosing with the testicular artery (internal spermatic artery in older texts).
What artery takes blood to the testis?
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. It is the male equivalent of the ovarian artery.
What nerve Innervates The cremaster muscle?
Innervation. The cremaster is innervated by sympathetic and somatic fibers of the genital branch of the genitofemoral nerve.
What passes through the spermatic cord?
The structures that pass through the deep inguinal ring and into the spermatic cord are the blood vessels to the testis, the testicular artery and vein, and the vas deferens, which passes over the pelvic brim and into the pelvis.
Where does Cremasteric artery come from?
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 Hesselbach’s triangle?
Hesselbach’s triangle or the inguinal triangle is a triangular area on the inferior interior aspect of the anterior abdominal wall within the groin.
What is the male organ that produces sperm?
testes Testicles (testes) The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
What is ductus deferens?
The ductus deferens, or vas deferens, is a fibromuscular tube that is continuation of the epididymis and is an excretory duct of the testis. Each ductus is 30-45 cm in length and serves to transport sperms cells from the respective epididymis to the ipsilateral ejaculatory duct.
How many veins are in the balls?
Below the subcutaneous inguinal ring, they unite to form three or four veins, which pass along the inguinal canal, and, entering the abdomen through the abdominal inguinal ring, coalesce to form two veins, which ascend on the Psoas major, behind the peritoneum, lying one on either side of the internal spermatic artery.
Can you control cremaster muscle?
The cremaster can also be contracted voluntarily, by performing Kegels (which somehow contracts the cremaster), or by flexing and tightening the abdominal muscles.
Can you cut the cremaster muscle?
What does this procedure involve? The procedure involves dividing the cremaster muscle tissue through an incision in your groin and then fixing the testis in your scrotum with one or more stitches to keep it in place.
Where is the cremaster located?
The cremaster muscle is found only within the male human body and covers the testis. The muscle moves the testis, promoting healthy and motile sperm. The cremaster muscle lowers and raises the testis in order to control its temperature.
Where is sperm stored?
epididymis A long tube that is located near each testicle. The epididymis is the tube which moves the sperm from the testicles. Vas deferens. This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac.
Are there 2 spermatic cords?
Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum during its descent it carries along with it vas deferens, its vessels, nerves etc. There is one on each side.
What does spermatic cord feel like?
Normally, the testicles are smooth, and the cord holding them feels like a rope. This cord is called the spermatic cord. Any swelling or lump in or on the scrotum is called a scrotal mass (see drawing).
Is sperm part of the spermatic cord?
Each cord is sheathed in connective tissue and contains a network of arteries, veins, nerves, and the first section of the ductus deferens, through which sperm pass in the process of ejaculation.
What does Cremasteric artery supply?
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 inguinal ring?
Superficial inguinal ring It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve, the genital branch of the genitofemoral nerve, and the spermatic cord (in men) or the round ligament (in women). At the other end of the canal, the deep inguinal ring forms the entrance.
What is the fascia Transversalis?
The transversalis fascia is a thin layer of connective tissue lining most of the abdominal cavity between the posterior surface of the transversus abdominis and superficial to the extraperitoneal fat and peritoneum.
What is arcuate line?
The arcuate line is the inferior margin of the posterior leaflet of the rectus sheath within the abdomen. The posterior leaflet of the sheath is formed, superficial to deep, from the: posterior part of the internal oblique aponeurosis. transversus abdominis aponeurosis.
What is Myopectineal orifice of Fruchaud?
The term [myopectineal orifice] was coined originally by Dr. Henri Fruchaud, and refers to a distinct area of weakness in the pelvic region. The word [pectineal] in this case refers to the pelvic bone area of origin of the pectinate muscle of the thigh. …
Is it healthy to eat sperm?
Yes, eating sperm is perfectly healthy as it is a bodily fluid. As semen is part of the body, it develops in the male reproductive system. Just like regular food, the constituents of sperm make it safe to ingest and digest. … The nutrients in sperm make it healthy to ingest.
How many minutes does it take a man to release sperm?
It takes, on average, two minutes for a man to ejaculate, but due to the differences between men and women, many men choose to learn to delay their orgasm in order to try to give more penetrative pleasure to female partners.
Does urine and sperm come from the same hole?
The glans penis is the slightly larger area towards the end of the penis and contains the opening of the urethra. The urethra. This is the tube which passes from the bladder down the penis to the outside. It carries both urine and semen.
Does ductus deferens carry urine?
Explanation: The vas deferens is an approximately 18cm long tube that commences from ductus epididymis and ends in ejaculatory duct. It carries seminal fluid from epididymis to ejaculatory duct. … Male urethra (unlike female urethra) carries both seminal fluid and urine.
What is the function of bulbar urethral gland?
The bulbourethral glands function to lubricate the spongy urethra for the passage of the ejaculate. Due to the alkaline pH of the excreted fluid, they also act to neutralize residual acidic urine that remains in the spongy urethra.
Can a single testicle have babies?
Yes, in most cases, people with one testicle can get someone pregnant. Remember, one testicle can provide enough testosterone for you to get an erection and ejaculate. This is also enough to produce adequate sperm for fertilization.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
