In the course of infertility consultation and treatment, it is often encountered that progesterone is needed, and the most applied and longest duration is after IVF egg retrieval, especially after pregnancy when longer-term progesterone support is needed. Recently, because patients frequently present with local abscesses requiring surgery after progesterone injection, or abnormalities such as pain and limited movement in the hip or even the affected limb, the majority of patients are reminded that they must come out of the misconception of progesterone injection to reduce pain in order to avoid adverse consequences due to pain and other reasons. At present, there are various dosage forms of progesterone that can be applied during pregnancy, and a large number of trials have confirmed that oral progesterone can completely replace the role of progesterone injections and reduce the tedium as well as the pain of daily injections. If you choose the cheaper oral form, the cost is not much different from the injections. So, don’t always think that “only injections work”.
