Overview
This study aims to evaluate the impact of hysteroscopic transcervical resection of the septum (TCRS) on fertility in infertile women without recurrent miscarriage, primarily assessing its effect on subsequent IVF-ET outcomes. The research attempts to answer: for infertile women with uterine septum planning to undergo IVF/ICSI (excluding preimplantation genetic diagnosis), does TCRS improve pregnancy outcomes (such as live birth rate, pregnancy rate, miscarriage rate, etc.) compared to non-surgical treatment (conservative observation), and to clarify the clinical value and safety of this surgical intervention.
Eligibility
Inclusion Criteria:
- (1) Meet the 2024 ASRM diagnostic criteria for uterine septate after 3D color Doppler ultrasound examination; (2) Aged between 20 and 40 years old; (3) Meet the diagnosis of infertility: those who have had regular sexual intercourse for at least 12 months but have not achieved clinical pregnancy; (4) Plan to undergo IVF/ICSI (non-PGD); (5) Sign the informed consent form and be able to accept and adhere to treatment and follow-up.
Exclusion Criteria:
- (1) Recurrent miscarriage; (2) Combined with untreated intramural uterine fibroids larger than 3 cm, intrauterine adhesions with an AFS score of ≥5 points; (3) Uncontrolled endocrine disorders, such as abnormal thyroid function (FT3, FT4 abnormal), hyperprolactinemia (greater than 2 times the upper limit of normal), combined with atypical endometrial hyperplasia or malignant lesions, acute inflammation of the reproductive system, coagulation dysfunction, etc.; if combined with endometrial polyps or submucosal fibroids, they can still be included in the group after resection; (4) Combined with adenomyosis (uterine body\>50 days of pregnancy), chocolate cysts with a diameter of\>4 cm, or severe dysmenorrhea and clear DIE lesions (diameter\>1 cm) can be palpated by gynecological triple examination; (5) Untreated severe hydrosalpinx (diameter\>3 cm) or hydrosalpinx with reflux confirmed by ultrasound; (6) Other important organ diseases and other surgical contraindications or relative contraindications; other conditions that are not suitable for assisted reproductive treatment; (7) Have participated in other interventional clinical studies (within the last three months).
