An evaluation of the use of G-CSF as an adjunct to IVF in women who have previously failed attempts at pregnancy with IVF
Background Recurrent IVF failures may result from implantation defects of which a thin endometrium is often implicated. Studies show that improved endometrial thickness increases the probability of successful IVF. Objectives To evaluate the effects of transcervical instillation of G-CSF as an adjunct to IVF. The study looked at the influence of G-CSF on the endometrium and on the achievement of pregnancy. Methods A retrospective cross-sectional study of women attending Bio ART Fertility Centre, who had two or more failed IVFs previously. Results There were a total of 49 women studied with a mean age of 38.9. Mean number of previous IVFs were 3.1. Comparison between those that achieved pregnancy and those that did not showed that age was a statistically significant factor (p-value 0.0005). Mean endometrial thickness pre and post-GCSF between the groups was not statistically significant (p-values >0.05). Conclusion With the use of G-CSF we achieved a clinical pregnancy rate of 34.69% and a statistically significant overall expansion of endometrial thickness (p-value 0.0029). However we failed to show any association between endometrial expansion and pregnancy outcome.
