At present, the in vitro luteal phase ovulation induction technique is safer, but there are advantages and disadvantages, and you need to choose a high grade professional reproductive hospital for ovulation induction. In vitro luteal phase ovulation promotion refers to the technique of using gonadotropins to stimulate the remaining immature residual follicles in the ovary to continue to mature in the luteal phase after the egg is discharged, and the time operation is more flexible. It is suitable for patients with low ovarian response, low ovarian reserve function and ovulation disorders. Luteal phase ovulation has its drawbacks. After the eggs obtained with this program are formed into embryos, it is still necessary to freeze the whole embryos first, and then perform frozen embryo resuscitation and transfer after menstruation, which increases the cost of in vitro fertilization. There is also the possibility of a stress reaction after stimulation of the ovaries, causing symptoms such as ascites, stabbing pain in the abdomen and chest tightness. It is recommended that women in need of assisted reproduction should go to a specialized fertility hospital and consult a professional doctor before choosing the luteal phase ovulation promotion program.
