If a woman is having an IVF-related embryo transfer, she still needs to take injections after the transfer, and at this time, the injection is progesterone, which aims to maintain the stability of the fetus in the uterus. After the embryo is transferred, its development in the body is still unstable, and progesterone is beneficial to the normal development of the embryo, therefore, it is necessary to take injections of progesterone, also known as progesterone, after the transfer. The injection of progesterone usually lasts for three months, and after the growth and development of the fetus has stabilized, it can grow normally without relying on external hormone supplementation. If a woman has an embryo transfer, she should carry out the relevant treatment and medication under the guidance of her doctor, follow all medical advice, and pay attention to adequate rest and appropriate exercise to promote the success of the embryo transfer.
