Patients with adenomyosis can be given GnRH, clinically 3-6 injections. Adenomyosis is caused by ectopic endometrium into the myometrium of the uterus, resulting in an increase in uterine volume, which may clinically cause painful periods, increased menstrual blood flow, and an increase in uterine volume, resulting in pelvic adhesions. Adenomyosis is related to ovarian function. When the ovaries are active, the uterine adenomyosis gradually increases in size. Clinically, Norelide can be used to inhibit the function of the ovaries, causing amenorrhea, which can relieve the symptoms of adenomyosis. Norelide can be used for 3 injections and no more than 6 injections at most to inhibit ovulation and improve the symptoms of adenomyosis.
