Question

Estrogen progesterone ratio increases during end of the 3rd trimester. This is responsible for increasing

• A. Lactation
• B. Uterine contractions
• C. Oxytocin secretion
• D. Dilation of uterus

Answer 1

Answer: (A)

Lactation

• The increased levels of oxytocin at the time of parturition are responsible for vigorous uterine contractions and the dilation of the uterus.
• The estrogen-progesterone ratio increases during the end of the 3rd trimester which results in the increased ability of the mammary glands for lactation.

So, the correct answer is 'lactation'.
