If the ovaries of a pregnant woman have to be removed during the first five months of pregnancy, a miscarriage results and the pregnancy fails. If the ovaries are removed in the last four months of pregnancy, the miscarriage does not occur. What is the reason for this? A. After the fifth month, the ovaries can regenerate rapidly B. The pituitary gland takes over the function of sustaining the pregnancy C. The placenta produces sufficient hormones to maintain the pregnancy D. Before removal the ovaries produce sufficient hormones to sustain the pregnancy

C. The placenta produces sufficient hormones to maintain the pregnancy
