About this study
Official title: A Randomized Controlled Trial of the Effect of the Granulocyte-macrophage Colony Stimulating Factor Gel on the Endometrial Thickness in Infertile Women With Thin Endometrium
The purpose of this study is to investigate the efficacy of the granulocyte-macrophage colony stimulating factor(GM-CSF) gel on the endometrial thickness in infertile women with thin endometrium.
Read the detailed description
The thin endometrium is detrimental to embryo implantation, probability of clinical pregnancy for an endometrial thickness ≤ 7 mm was significantly lower compared with cases with endometrial thickness > 7 mm. It has been reported the granulocyte colony stimulating factor (G-CSF) increased the endometrial thickness and pregnancy rate of infertile women with thin endometrium during IVF cycle. However, most of the researches were retrospective and small sample size, and the results were conflicted among them. GM-CSF is another member of CSF superfamily, recalling more macrophage than G-CSF, which could be more effective in local homeostasis maintain and wound repair. GM-CSF has been widely used in skin repair after burn. It was also found the GM-CSF and its receptor in endometrium. In the past year, the investigators tried GM-CSF irrigation in 21 women with thin endometrium and most of them received GM-CSF after hysteroscopic examination or slight adhesion relaxing, and the preliminary data suggested that the GM-CSF may promote the endometrial growth. Does the GM-CSF gel can improve the endometrial thickness? Therefore, this study was conducted.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GM-CSFDrug
Also called granulocyte-macrophage colony stimulating factor
3ml GM-CSF gel will be irrigated into the uterine cavity immediately when hysteroscopy is complete. Then same dose gel will be given every other day twice
17-ß estradiolDrug
Also called Femoston
A hormone replace treatment by 17-ß estradiol (6mg per day) follows next cycle to prepare for embryo transfer
| Study group | Role | What they receive |
|---|---|---|
| GM-CSF | Experimental | Hysteroscopy will be arranged to confirm the uterine cavity is normal and there is no significant intrauterine adhesion.

| Control | Experimental | Hysteroscopy will be arranged to confirm the uterine cavity is normal and there is no significant intrauterine adhesion.
After hysteroscopy examination, nothing was applied to the uterine cavity. Receives: Drug: 17-ß estradiol |
What is being measured
The primary outcome is the main question the study is designed to answer.
the endometrial thickness
the endometrial thickness following the hormonal replacement treatment evaluated based on the ultrasound
Measured: 1 months after hysteroscopy examination
Secondary outcomes (3)
embryo transfer cancelation rate
according to the patients' wishes
Measured: 2 months after hysteroscopy examination
uterine artery blood supply markers
uterine artery blood supply markers, such as PI, reflux index(RI) and S/D, evaluated based on the 3-D ultrasonography
Measured: 1 months after hysteroscopy examination
pregnancy rate
pregnancy rate after frozen embryo transfer
Measured: 3 months after hysteroscopy examination
