Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Granulocyte colony-stimulating factor (G-CSF).
300micrograms in 1 ml saline administered through the cervix, into the uterine cavity as a single dose via an embryo transfer catheter 5 days prior to blastocyst replacement.
Intervention code [1] 266767 0
Treatment: Drugs
Comparator / control treatment
The patient will act as their own internal control, as to be included their endometrium has not thickened despite optimal therapy and have not developed an endometrium of greater than 7.0mm in thickness.

They must have embarked on a natural cycle, hormone replacement stimulated cycle and a gonadotrophin hormone stimulated cycle (in any order) and have not developed an endometrial thickness of 7mm by any approach within the preceding year.

Study design
Purpose of the study
Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients who have an unresponsive endometrium will be offered the intervention. As they will be unrepsonsive to treatment- they will be therefore act as their own historical control; pre and post intervention.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
non-randomised
Masking / blinding
Open (masking not used)

Summary
Brief summary
There is some preliminary evidence that the endometrial administration of granulocyte colony-stimulating factor (G-CSF) several days prior to embryo replacement leads to a substantial and rapid improvement in endometrial thickness . The rationale for its use is that it is has successfully been used in the treatement of recurrent miscarriages. Granulocyte colony-stimulating factor (G-CSF) is a cytokine which stimulates neutrophilic granulocyte proliferation and differentiation. It is expressed and produced by the decidual cells, and its receptor, c-fms, is expressed by the trophoblastic cells. In addition, in an animal model, G-CSF showed a marked anti-abortion activity. G-CSF is safely used in the treatment of neutropenia during cancer chemotherapy, and no embryotoxic effects of this substance have been reported and its safety profile is reassuring. Since experimental findings showed a positive effect on the trophoblast and particularly thickening of the endometrium in previously very resistant patients we would like to prospectively observe the influence of G-CSF on endometrial development in patients with poor endometrial development. It has a very short half life and is administered to the endometrial cavity 5 days prior to embryo replacment so it is not present in the endometrial cavity when the embryo is placed in the uterus.
