Question 3

One structure that is important in the pathway of sperm through the male body is the spermatic cord. Discuss the importance of the spermatic cord, including structures that pass through it and its functions in the life of sperm.

Accepted Answer

How the spermatic cord is a bundle of structures that connect the external testicles with internal body structures. It runs through the inguinal canal, an opening or tunnel through the abdominal wall in the groin.
How the inguinal canal is a region where the body wall is weaker; this sometimes results in inguinal hernias, or ruptures in which part of the intestine bulges through the abdominal wall.
How the cremaster muscle surrounds the spermatic cord and also forms a sling around the testicle. This muscle helps regulate temperature in the testicles. It contracts automatically in the cold, causing the testicles to move closer to the body and stay warmer.
The spermatic cord contains the vas deferens, and the arteries, veins, and nerves that supply the testicles. The vas deferens carries sperm from the epididymis to the outside of the body.
