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 .
in males: the spermatic cord [12] and its coverings, and the ilioinguinal nerve. in females: the round ligament of the uterus, and the ilioinguinal nerve. The classic description of the contents of the spermatic cords in the male are: 3 arteries: artery to vas deferens (or ductus deferens), testicular artery, cremasteric artery;
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 testicle remains connected to its blood vessels and the vas deferens, which make up the spermatic cord and descend through the inguinal canal to the scrotum. The deep inguinal ring, which is the beginning of the inguinal canal, remains as an opening in the fascia transversalis, which forms the fascial inner wall of the spermatic cord.
This is attached to the testis and extends through the inguinal canal to the wall of the scrotum as a testis. It carries with it the ductus deference, which are testicular vessels and nerves, a portion of the abdominal muscle, and lymph vessels. All of the structures remain attached to the testis and form what is known as the spermatic cord.

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
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.
