The male reproductive system comprises of different organs, including a pair of testis, a pair of vas deferens, a pair of epididymis, a pair of vasa efferentia, a urinogenital tract, a pair of seminal vesicles, a prostate gland, a pair of Cowper’s gland and a penis. Similarly, the female reproductive system has several different structures including ovaries, fallopian tubes, uterus, vagina, accessory glands, and external genital organs. Vas deferens carries sperms to the ejaculatory duct while fallopian tube carries oocyte for the fertilization. There is a pair of vas deferentia in a male body while there is a pair of fallopian tubes in a female body.

What is Vas Deferens?
Vas deferens (plural: vas deferentia) is a muscular tube-like structure that transports sperms from the epididymis to the penis and stores sperms until the time of ejaculation. Male reproductive system has a pair of vas deferentia. Each epididymis opens into a vas deferens.
VAS延期的长度约为30厘米。它的直径小于四分之一英寸(5毫米)。通常,VAS递延比其余的琴弦更厚,更牢固。它也不那么令人费解,大部分折叠处在两个结构之间的过渡中。VAS延迟由上皮组织的内壁(伪分层柱状上皮),结缔组织和内脏肌肉的中间层以及一个外生的外层(are骨结缔组织)制成。
什么是输卵管?
Fallopian tube is a part of the female reproductive system. There are two fallopian tubes in the female reproductive system. Each one is associated with each ovary. The end of the fallopian tube is near the ovary, and it expands to form a funnel-shaped infundibulum surrounded by fingerlike extensions called fimbriae. However, infundibulum does not contact the ovary. Once released from the ovary, oocyte enters the peritoneal cavity and then enters the fallopian tube.
The inner surface of the fallopian tube has cilia, which facilitate the movement of the oocyte through the tubes. Generally, the journey of the oocyte through the Fallopian tube takes about 7 days until fertilization takes place. Therefore, the fallopian tube is the place where the fertilization or the fusion of sperm and egg takes place.
What are the Similarities Between Vas Deferens and Fallopian Tube?
- Vas deferens and fallopian tube are two structures that belong to reproductive systems of humans.
- There are two vas deferentia in males and two fallopian tubes in females.
- Both are muscular tube-like structures.
- Both structures carry sex cells.
What is the Difference Between Vas Deferens and Fallopian Tube?
Vas deferens is a tiny tube through which sperms pass from epididymis to penis while fallopian tube is a slender tube through which eggs pass from an ovary to the uterus. So, this is the key difference between vas deferens and fallopian tube. Vas deferentia belong to the male reproductive system while fallopian tubes belong to the female reproductive system.
Below infographic shows more details of the difference between vas deferens and fallopian tube.
概括– Vas Deferens vs Fallopian Tube
Vas deferens is a small muscular tube in the male reproductive system that transports sperms from the epididymis to the penis. There are two vas deferentia in the male reproductive system. In contrast, fallopian tube is a muscular tube that facilitates the movement of oocyte for the fertilization. Similar to vas deferens in the male reproductive system, there are two fallopian tubes in each female reproductive system. So, this is the summary of the difference between vas deferens and fallopian tube.
