Patient's question:
NoDoctor's answer:
Midtrimester induction of abortion is difficult and carries significant risks, with a high incidence of complications. During this period, the placenta produces a large amount of progesterone, and the uterus is in a "suppressed" state, with poor cervical maturity and congestion. Inducing labor is challenging because it is difficult to provoke uterine contractions. Additionally, since the fetal skeleton and placenta have already formed in the second trimester, achieving fetal expulsion requires full cervical dilation. However, physiologically, the cervix is hard during the second trimester. To soften the cervix, apart from using uterotonic agents to induce passive dilation, directly softening the cervix would actively shorten contraction time and alleviate patient suffering.
