研究目的:

比较宫腔灌注不浓度PRP治疗薄型子宫内膜的FET患者的结局,包括内膜厚度、形态、血流分级,以及胚胎种植率、生化妊娠率、临床妊娠率、早期流产率等FET助孕结局。探讨不同浓度 PRP在薄型子宫内膜治疗中的应用价值,寻找更为合适宫腔灌注PRP浓度,为临床治疗方案提供新依据。  

Objectives of Study:

This study aims to compare the effects of intrauterine perfusion with varying concentrations of platelet-rich plasma (PRP) on FET outcomes in patients with thin endometrium. Key endpoints include endometrial parameters (thickness, morphology, blood flow) and reproductive outcomes (implantation rate, biochemical pregnancy, clinical pregnancy, early miscarriage). The goal is to explore the therapeutic value of different PRP concentrations, determine an optimal concentration for clinical use, and provide a new basis for treatment protocols.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄≤40岁;
2.既往曾因自然周期、促排卵周期人绒毛膜促性腺激素(HCG)日、或人工周期内膜转化日因内膜厚度<7mm取消移植;
3.宫腔镜检查,子宫形态正常,如有宫腔粘连,术中以完整分离粘连,术后三维超声检查,未发现粘连复发征象;
4.甲状腺功能、血糖血脂均正常;
5.不孕因素主要包括盆腔输卵管因素、排卵障碍、男方因素,无合并其他内外科疾病。

Inclusion criteria

1.Age <= 40 years. 2.Previous cancellation of embryo transfer due to an endometrial thickness of < 7 mm on the day of human chorionic gonadotropin (hCG) administration in a natural or ovulation induction cycle, or on the day of endometrial transformation in a hormone replacement cycle. 3.Normal uterine cavity confirmed by hysteroscopy. If intrauterine adhesions were present, they must have been completely lysed during the procedure, with no signs of recurrence on postoperative three-dimensional ultrasonography. 4.Normal thyroid function, blood glucose, and blood lipid profiles. 5.Infertility attributable mainly to pelvic/tubal factors, ovulatory dysfunction, or male factors, with no significant concurrent medical or surgical diseases.

排除标准:

4.子宫腺肌症;
5.子宫内膜异位症III-IV期;
6.双侧输卵管严重积水;
7.反复种植失败;
8.无囊胚冻存者;

Exclusion criteria:

1.History of estrogen-related malignancies;
2.Abnormal uterine cavity on hysteroscopy (e.g., untreated submucosal uterine fibroids);
3.Endometrial pathologies, including but not limited to endometrial hyperplasia, endometrial tuberculosis, or untreated endometritis.
4.Adenomyosis;
5.Endometriosis of American Society for Reproductive Medicine (ASRM) stages III-IV.
6.Severe bilateral hydrosalpinx;
7.History of recurrent implantation failure;
8.Unavailability of cryopreserved blastocysts for transfer;
