1. Situations that require hysteroscopy
History of uterine abnormalities: repeated miscarriages, multiple intrauterine surgeries (such as abortion, uterine curettage) or history of pelvic tuberculosis.
▶ Imaging findings indicate abnormalities: Ultrasound reveals polyps in the endometrium, adhesions, fibroids, or abnormalities in the shape/thickness of the endometrium.
▶ Repeated unsuccessful embryo transfers: If there are ≥2 failed embryo transfers without implantation, it is necessary to investigate potential issues in the uterine cavity (such as endometritis or adhesions).
▶ Unintended infertility or thin endometrium: It is necessary to directly examine the uterine cavity environment to rule out any hidden abnormalities.
For those with the first test tube without the above risk factors, hysteroscopy may not be performed if routine examinations such as B-ultrasound do not indicate abnormalities.
For those with their first IVF procedure and no aforementioned risk factors, and when routine examinations such as ultrasound do not reveal any abnormalities, hysteroscopy may not be necessary.
For young patients (e.g., those under 35 years old) who have no history of miscarriage or intrauterine procedures, the success rate is usually not affected.
Timing: The examination should be conducted 3 - 7 days after menstruation is clean, and sexual life is prohibited before surgery.
▶ Timing: It is recommended to undergo the examination 3–7 days after menstruation ends. Sexual activity should be avoided before the procedure.
▶:,,(<1%).Rest for 1 - 2 weeks after surgery to avoid strenuous exercise.
▶ Individualized decision-making: Ultimately, it is necessary for doctors to consider factors such as age, medical history, and ultrasound results in order to weigh the pros and cons.
(,),.It is recommended to actively inspect high-risk groups, and priority for non-invasive evaluation is given to low-risk groups.
