Testicles in the inguinal canal
During the embryonic development the testis is formed in the boy in the lumbar region. Only then does the testis descend within the body, pass the inguinal canal and reach the scrotum. Here the testis follows the so-called scrotal ligament, which is also called gubernaculum testis.
If this process is disturbed, the newborn infant may develop an undescended testicle. In this case the testicle remains in the inguinal canal. The reasons for this are usually hormonal in nature.
Premature babies are particularly affected. In some cases, however, the testicle does not migrate into the scrotum until after birth. In adults, too, the testicle may under certain circumstances return to the inguinal canal by pressure.
Spermatic cord
The spermatic cord (Funiculus spermaticus) runs in the male inguinal canal. It contains: You can find more information under our topic: Spermatic cord
- The spermatic duct (Ductus defferens)
- Blood vessels. The artery and vena testicularis are distinguished from the artery and vena ductus deferentis which supply the testicles, the artery and vena ductus deferentis which supply the vas deferens and the arteria and vena cremasterica which supply the cremasteric muscle (also known as the scrotor lifter) with blood.
- Nerves and nerve plexuses. The plexus testicularis for the innervation of the testicles and the plexus ductus deferentis for the innervation of the vas deferens. In addition, vegetative nerve fibers and lymph vessels are also found in the spermatic cord.
