Unruptured follicle luteinization syndrome (LUFS) refers to a series of symptoms caused by the luteinization of the follicle when it grows to a certain period and does not rupture and ovulate, which is a special type of ovarian ovulatory dysfunction. Some women usually like to use ovulation test strips to monitor whether they are ovulating or not, and when they see two red lines, they think they are ovulating without problems. Why is that? This is because the ovulation test strips are designed to detect the presence or absence of LH peaks in the body. Generally, ovulation occurs when LH peaks are present, but in the case of luteinization of unruptured follicles syndrome (LUFS) we mentioned, ovulation is impaired. Therefore, for women whose male partner is fine, whose female partner’s fallopian tubes are open, and whose ovulation test shows an LH peak but who have been trying to conceive for some time but still have not conceived, they can choose ultrasound to monitor ovulation so that they can find out if they have luteinization of unruptured follicles syndrome (LUFS). The cause of this condition is not well understood. Most believe that it is related to central regulatory disorders, local disorders and psychiatric and psychological factors. The incidence of LUFS varies, but most believe that it is about 5%-10% in natural menstrual cycles and about 30%-40% in pharmacological ovulation cycles. According to ultrasound dynamic monitoring, it can be divided into three types: small follicular type, follicular retention type and persistent enlargement type. Currently, the following treatment options are available: 1. Ovulation promotion therapy: Before applying ovulation promotion therapy, the local mechanical factors causing LUFS, such as endometriosis, chronic pelvic inflammatory disease and pelvic adhesions, must be actively treated. 2.Surgical treatment: It can be divided into selective follicular puncture treatment, laparoscopic or cesarean surgical treatment 3.Spiritual psychotherapy: mental decisive tension and anxiety can lead to the occurrence of LUFS, and spiritual psychological counseling treatment section can help restore normal ovulation function.
