Brief summary

Recently, scientists look into G-CSF (Granulocyte - Colony Stimulatin Factor). The use of this molecule is increasing in reproduction pathology. High level of follicular and blood G-CSF on the day of oocyte retrieval could correlate with higher pregnancy and implantation rates.

Interventions

PROCEDUREBlood test

Taking blood sample of the patient during the day 3, triggering day, oocyte collection day and pregnancy test day. Taking the follicular fluid during the oocyte collection day
