In vitro fertilization (IVF) may cause some stimulation and impact on the ovaries of women due to the need for ovulation promotion, but there are usually no conscious symptoms, and if there is no pregnancy, it can be recovered after a post-operative period, and in a very few severe cases, ovarian hyperstimulation may occur, which is a complication unique to IVF, but it rarely occurs under close monitoring of follicle development, and even if it occurs, there are corresponding countermeasures. There is no need to worry. If IVF is performed without anesthesia, there may be pain and other uncomfortable sensations during the puncture for egg retrieval, but if intravenous anesthesia is administered for egg retrieval, the patient will sleep and will not feel any pain. There is no discomfort for the patient during the transfer.
