This causes the cervix to swell, decreasing the chance a sperm could pass into the uterus.Which of the following hormones is not matched correctly to itseffect on the mother? a. peptide hormones—increased resistance to insulin b. progesterone—reduced chances of the mother having an immune reaction to the fetus c. estrogen—increased uterine blood flow d. progesterone—relaxation of smooth muscle and decrease in blood pressure e.
