Estrogen levels increase steadily during pregnancy and reach their peak in the third trimester. Progesterone levels also are extraordinarily high during pregnancy. The changes in progesterone cause a laxity or loosening of ligaments and joints throughout the body.

Answer 2

Increase in oestrogen and progesterone ratio during pregnancy is helpful in​ childbirth.

• The increasing ratio of oestrogen to progesterone results in the weakening of the myometrium that makes it more sensitive and thereby promoting uterine contractions.

• Higher levels of progesterone inhibit the uterine contractions and thereby maintain pregnancy. On the other hand, the given scenario( higher estrogen) promotes labour.

• Higher levels of oxytocin along with estrogen promote the secretion of prostaglandins, that further aid the process.

• The uterine contractions initiate true labour and are followed by the stages of childbirth.
