Does Flushing the Uterine Cavity With Follicular Fluid After Ovum Pick-up Improve Implantation Rates in ICSI Cycles?
Traditionally during ovum pick-up in ICSI, we aspirate the follicles for oocyte retrieval but unfortunately we don't make use of the follicular fluid (FF) and we discard it in spite of the fact that this does not happen in nature. The fallopian tube picks-up the FF with the oocyte during ovulation. As this fluid contains stem cell factor and C-Kit receptor responsible for implantation and IGF responsible for endometrial growth and TGF that improves implantation. That's why flushing the endometrial cavity with FF after ovum pick-up might improve endometrial receptivity and implantation rates; the limiting step in ICSI.
Patients and Methods:
100 patients attending kasr El-Aini IVF center preparing for ICSI cycles are randomized into two groups. In the study group, flushing the endometrial cavity with 2ml of clear follicular fluid surrounding mature oocytes through an IUI catheter is done after ovum pick-up While in the control group, no flushing of the endometrial cavity with FF is done. The implantation rates and pregnancy rates in both groups will be assessed.

|Official Title:||Phase I Study of the Effect of Flushing the Uterine Cavity With Follicular Fluid After Ovum Pick-up on Implantation Rates in ICSI Cycles|
- pregnancy rate [ Time Frame: 17 days ] [ Designated as safety issue: No ]The main outcome is the pregnancy rate in ICSI cycles after flushing the uterine cavity with follicular fluid after ovum pick-up in the study group and comparing it with the control group.
- Implantation rate [ Time Frame: 17 days ] [ Designated as safety issue: No ]The secondary outcome is the implantation rate in ICSI cycles after flushing the uterine cavity with follicular fluid after ovum pick-up in the study group and comparing it with the control group.
