About this trial

This is an interventional treatment trial for Infertility, Female focused on measuring Thin Endometrial Infertility, hUCMSCs

Eligibility Criteria

20 Years - 39 Years (Adult)FemaleDoes not accept healthy volunteers

Inclusion Criteria:

  1. Patients aged 20 to 39 years with primary or secondary infertility who have received ivf embryo transfer treatment and have been frozen at least 4 good quality embryos (good quality embryos defined as 7-9C / ⅱ 0 or 4BC or more blastocysts and ≥2 grade ⅰ embryos or 4BC or more blastocysts)
  2. Once above 2 times under hysteroscopy surgery adhesions, uterine cavity form has returned to normal, with normal menstrual cycle or at least a cycle high-dose estrogen replacement therapy for more than 12 days (> 4 mg/day, maximum dose of more than 8 mg/day), after treatment the biggest endometrial thickness of 7 mm or less or upper middle period of endometrial thickness of 7 mm or less on average; Or received assisted reproductive therapy, after at least 4mg/ day of estrogen, colony stimulating factor, aspirin, sildenafil and other drugs, unknown maximum endometrial thickness ≤7mm or average endometrial thickness ≤7mm in middle and upper segment; The maximum endometrial thickness in luteal phase was less than 6mm

Outcomes

Primary Outcome Measures

Pregnancy outcome
Pregnancy status is tracked for pregnancy rate, clinical pregnancy rate, ongoing pregnancy rate, miscarriage rate and live birth rate.

Secondary Outcome Measures

Intrauterine adhesion patients efficacy evaluation
Evaluated by Ultrasound B. The endometrium thickness increased ≥ 2mm and "B" or "A" endometrium appeared in the endometrium proliferation stage.
Irregular menstruation patients efficacy evaluation
Evaluated by Menstrual Blood Volume Scale. The menstrual cycle returned to normal and menstrual volume improved.
Poor endometrial receptivity patients efficacy evaluation
The criterion is clinical pregnancy and supplemented with ERT detection.

5. Study Description

Brief Summary
To explore the therapeutic effect and safety of human umbilical cord mesenchymal stem cells on thin endometrial infertility and to explore whether human umbilical cord mesenchymal stem cells using collagen as the carrier can promote endometrial growth, reduce the recurrence rate of intrauterine adhesion, increase the clinical pregnancy rate, improve the pregnancy outcome, and study its safety.
Detailed Description
This is a random, open label, and self-control experiment. 24 patients are selected and sign consent forms, then divided into two groups. Doctors collect the basic information of patient (including age, BMI, mental condition, vital sign, history of disease, pharmaco-history, and so on.), evaluate the symptom of thin endometrial infertility (menstrual conditions, uterine cavity form, pregnancies). All patients receive laboratory and image examination as baseline. Then, cell treatment will be given based on the clinical protocol. Doctors have follow-up visit on 1, 3, 6, 12 month after treatment, and do efficacy evaluation.
