Question

The amniotic fluid volume is maximum at?

• A. 32 weeks
• B. 34 weeks
• C. 36 weeks
• D. 40 weeks

Hint:

The liquor peaks near 1 litre in the early third trimester, then falls before term.

Answer 1

The Correct Option is C

Step 1: Liquor amnii is produced and reabsorbed continuously, and its net amount tracks an inverted curve across gestation - climbing first, then receding.

Step 2: The curve crests close to 1 litre in the early third trimester, specifically near 36 weeks of pregnancy.

Step 3: From that crest onward the volume tapers, so by the time of full term at 40 weeks it has already fallen to about 600 to 800 mL.

Step 4: This is precisely why post-dated pregnancies are watched for low fluid (oligohydramnios). The peak therefore sits at 36 weeks.

\[\boxed{\text{36 weeks}}\]
