Most common site for Fertilization is :
- Ampulla
- Isthmus
- Intramural
- Fimbriae
The Correct Option is A
Solution and Explanation
Fertilization in human reproduction most commonly occurs in the ampulla of the fallopian tube. The fallopian tube is a conduit between the ovaries and the uterus, and it is divided into several parts, each playing a role in transporting the egg and sperm:
- Ampulla: This is the widest section of the fallopian tube and is the most common site for fertilization. The environment here is optimal for sperm to meet and fertilize the egg.
- Isthmus: This narrow portion connects the ampulla to the uterus. It is not typically the site of fertilization.
- Intramural: This part integrates with the uterine wall, serving mainly as a passage; fertilization rarely occurs here.
- Fimbriae: These finger-like projections help capture the released egg from the ovary but do not play a direct role in fertilization.
Therefore, among the given options, the ampulla is indeed the most common site for fertilization.
