In vitro injections need to be considered in a comprehensive manner depending on the woman’s condition, with the long protocol taking 20 days and the short protocol taking about 10 days. If a woman has poor follicular development or ovulation, she needs to obtain good quality eggs to grow up, during which time she needs to be given medication to promote follicular development, including 8-10 days of gonafine injections and chorionic gonadotropin to promote egg expulsion. Since these drugs are hormones, women need to use small, regulated doses according to their doctor’s orders and dynamically observe the growth and development of the follicles. If overdosed, it can easily lead to ovarian hyperstimulation syndrome, which is not conducive to obtaining good quality eggs and can also have a negative impact on a woman’s health, so women should be evaluated by a doctor before making a decision if they want to have IVF injections.
