Brief Summary:
Thin endometrium will lead to hypomenorrhea,infertility and recurrent pregnancy loss and there are few effective methods to increase the endometrial thickness and improve the fertility outcomes. Patients with thin endometrium will be divided into three groups and receive estrogen therapy, stem cell therapy and growth factor therapy respectively. This randomized controlled clinical study is carried out to explore the optimal treatment method and best indications for thin endometrium.

Condition or disease Intervention/treatment Phase

A collagen scaffold loaded with BMMNCs will be transplanted into the uterine cavity after hysteroscopy under the guidance of ultrasound

Experimental: Estrogen Drug: Estrogen
Patients will receive regular estrogen therapy

Primary Outcome Measures :

Secondary Outcome Measures :
  1. Endometrial blood flow [ Time Frame: 6 months ]
    Endometrial blood flow evaluated by transvaginal sonography
