The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis , is an extension of the peritoneum that passes through the transversalis fascia .
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. [11]
It then descends within the spermatic cord. In males, it passes through to the scrotum, where it supplies the cremaster, dartos muscle and gives a few filaments to the skin of the scrotum. In females, it accompanies the round ligament of the uterus, where it terminates as the nerve supplying the skin of the labia majora and mons pubis. [1]: 343
m, m. Right and left Müllerian ducts uniting together and running with the Wolffian ducts in gc, the genital cord: m. Müllerian duct, the upper part of which remains as the hydatid of Morgagni; the lower part, represented by a dotted line descending to the prostatic utricle, constitutes the occasionally existing cornu and tube of the uterus ...
Within the spermatic cord, the vas deferens is situated posterior (and parallel to) the vessels of the spermatic cord. [3]: 1297 The vas deferens traverses the inguinal canal to reach the pelvic cavity; it enters the pelvic cavity lateral to the inferior epigastric vessels. At the deep inguinal ring, the vas deferens diverges from the ...
The larger size of their inguinal canal, which transmitted the testicle and accommodates the structures of the spermatic cord, might be one reason why men are 25 times more likely to have an inguinal hernia than women. Although several mechanisms such as strength of the posterior wall of the inguinal canal and shutter mechanisms compensating ...
The vaginal process between the abdominal inguinal ring and the superior part of the testis is then obliterated, usually leaving a string-like or cord-like remnant adjacent to the spermatic cord. [2] If the vaginal process fails to obliterate, the communication between the peritoneal cavity and scrotum persists after birth, predisposing the ...
The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
