In vitro fertilization refers to the use of ovulation stimulation drugs under the guidance of a doctor, which allows a woman to release multiple eggs during ovulation and can appropriately increase the probability of success of the IVF procedure. In ovulation promotion, the drugs used need to be based on a number of aspects such as the patient’s ovarian condition, hormone levels and age to formulate the drug use program. During the 2~5 days of ovulation induction, after injecting the drugs, you need to go to the hospital every day for blood draw or ultrasound test, which can facilitate the doctor to observe the changes of hormone levels in the female body as well as the development of follicles, and then according to this relevant information to timely adjust the use of drugs until the follicles are mature, and then prepare for egg retrieval. During the ovulation stage, it is recommended to supplement some high-quality proteins, such as chicken, beef, etc., which can improve the quality of the generated eggs, and the quality of the embryos can be improved, which is conducive to IVF transplantation.
