精子绳和腹股沟管之间的差异

Thekey difference在精子绳和腹股沟管之间是spermatic cord is a collection of vessels, nerves and ducts that run to and from the testes while the inguinal canal is a passage that allows the spermatic cord to pass through.

精子绳和腹股沟管是两种类型的管状结构男性生殖系统。其中，精子绳穿过腹股沟管。而腹股沟管是前腹壁的通道，它传达了男性的精子线。精子线是往返于睾丸的血管，神经和管道的集合。同样，腹股沟管较大，而腹股沟较大，精子绳较短。此外，每个睾丸都有两个精子绳以及两个腹股沟管。

What is Spermatic Cord?

Spermatic cord is the cord-like structure in males, formed by thevas deferensand surrounding tissue called fascia. It is a collection of vessels, nerves and ducts. It runs from the deep inguinal ring down to each testicle. There are two spermatic cords running from each testicle. Structurally, three layers of tissues ensheath the spermatic cord. They are external spermatic fascia, cremasteric muscle and fascia and internal spermatic fascia. The diameter of the spermatic cord is around 16 mm, and it is relatively short.

Spermatic cord starts at the deep inguinal ring, passes through the inguinal canal, enters the scrotum via the superficial inguinal ring, continues into the scrotum and ends at the posterior border of the testes. The primary function of the spermatic cord is facilitating the passage of精液。此外，它由重要的血管和神经组成。有时，有必要在精子绳上进行手术，以保留睾丸的血液供应和导管延迟的连续性。

What is Inguinal Canal?

腹股沟管是一种通道，在前腹壁上向下延伸。此外，它与腹股沟韧带相似。腹股沟运河用作几个结构从腹壁传递到外生殖器的运河。精子绳穿过腹股沟管。有两个腹股沟管，每侧一个。

Moreover, the inguinal canal has two openings as superficial and deep rings. Deep inguinal ring is the entrance of the inguinal canal. Generally, the length of the inguinal canal is about 4 – 6 cm. There are four main parts of the inguinal canal: floor, anterior wall, posterior wall, and roof.

What are the Similarities Between Spermatic Cord and Inguinal Canal?

• Spermatic cord and inguinal canal are two parts of the male reproductive system.
• The spermatic cord passes through the inguinal canal.
• There are two spermatic cords and two inguinal canals in each male reproductive system.

What is the Difference Between Spermatic Cord and Inguinal Canal?

The spermatic cord is a group of structures including vas deferens, arteries, veins, lymphatic vessels, and nerves that pass through the inguinal canal to the testis while the inguinal canal is a passage that facilitates the running of several structures, especially spermatic cord, through it. So, this is the key difference between spermatic cord and inguinal canal. Besides, the spermatic cord is smaller in diameter and length than the inguinal canals. Thus, this is the structural difference between spermatic cord and inguinal canal.

此外，精子绳始于下腹部，在阴囊末端结束。但是，腹股沟管位于腹股沟韧带上方的前腹壁中。此外，精子绳促进了精液的通过，而腹股沟管则是一条途径，结构可以从腹壁传递到外生殖器。因此，这是精子绳和腹股沟管之间的功能差异。

总结——精索与腹股沟管

In short, the spermatic cord is a bundle of structures including vas deferens, arteries, veins, lymphatic vessels, and nerves that pass through the inguinal canal to the testis. There are two spermatic cords in the male reproductive system. The cords extend from the testes to the inguinal rings. Inguinal canal is a passage in the lower anterior abdominal wall, superior to the inguinal ligament. Spermatic cord runs through the inguinal canal. Thus, this summarizes the difference between spermatic cord and inguinal canal.
