Question

Most common site for Fertilization is :

• A. Ampulla
• B. Isthmus
• C. Intramural
• D. Fimbriae

Answer 1

The Correct Option is A

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.
