Question

At which week of pregnancy does Human Chorionic Gonadotropin (hCG) typically reach its peak?

• A. 4–5 weeks
• B. 8–10 weeks
• C. 16–18 weeks
• D. 24–26 weeks

Hint:

{hCG levels rise rapidly in early pregnancy and peak at about 8–10 weeks}, after which they gradually decline.

Answer 1

The Correct Option is B

Concept: Human Chorionic Gonadotropin (hCG) is a hormone produced by the trophoblastic cells of the placenta during pregnancy. It plays a key role in maintaining the corpus luteum and supporting progesterone production in early pregnancy. The level of hCG rises rapidly during the first trimester and is commonly used as a marker for pregnancy detection.
Step 1: Identify the period when hCG levels are highest.

• 4–5 weeks – hCG begins to rise.
• 8–10 weeks – hCG reaches its peak concentration.
• 16–18 weeks – hCG levels begin to decline.
• 24–26 weeks – hCG stabilizes at lower levels.

Therefore, the peak level of hCG occurs around 8–10 weeks of pregnancy.
