The amount of cul-de-sac fluid reaches peak volume in the early ______ phase.

Explanation:
Pelvic free fluid varies with the menstrual cycle. Estrogen-dominant phases keep cul-de-sac fluid relatively minimal, while after ovulation the rise in progesterone and the shift to a secretory endometrium increase vascular permeability and fluid production in the pelvis. This combination leads to the greatest amount of cul-de-sac fluid during the early luteal phase. A small amount can be normal, but a larger volume may require further assessment.
