Triptorelin is given after fertilized egg transfer to inhibit gonadotropin secretion and improve the success of implantation. Triptorelin is a gonadotropin-releasing hormone that, when administered after transplantation, acts as a pituitary down-regulator, inhibiting the secretion of gonadotropins such as follicle stimulating hormone and luteinizing hormone. Secondly, the half-life of treprostinil is relatively long, so it can continue to affect the pituitary gland for a long time, ensuring the stability of the embryo after the transfer. However, it should be noted that after the injection of Triptorelin, adverse reactions such as bleeding, vaginal dryness, depression, increased levels of liver enzymes and visual disturbances may occur, so it is important to closely monitor the body dynamics after use. Secondly, it is forbidden to use it in patients who are allergic to the product, non-hormone-dependent prostate or after prostatectomy. After transplantation, it is important to follow the doctor’s instructions to inject Triptorelin, as well as to take good care of the patient and go to the hospital for regular checkups.
