Is granulocyte colony-stimulating factor level predictive for human IVF outcome?

Area of Science:

• Reproductive Endocrinology
• Infertility Research
• Granulocyte Colony-Stimulating Factor (G-CSF) Biology

Background:

• Investigated the role of granulocyte colony-stimulating factor (G-CSF) in human reproduction.
• G-CSF is a key cytokine in immune responses and has emerging roles in reproductive processes.

Purpose of the Study:

• To explore the association between G-CSF levels and outcomes in assisted reproductive technologies.
• To determine if G-CSF can serve as a predictive marker for in vitro fertilization (IVF) success.

Main Methods:

• Serum and follicular fluid (FF) G-CSF levels were analyzed in 93 patients undergoing IVF.
• G-CSF levels were compared across different ovarian response groups (low, moderate, high) and during the menstrual cycle.
• G-CSF was also assessed in patients with endometriosis.

Main Results:

• G-CSF concentration was significantly higher in follicular fluid compared to serum.
• Serum G-CSF levels positively correlated with ovarian response and pregnancy rates following IVF.
• In pregnant patients, G-CSF levels increased from embryo transfer through gestation.
• Lower G-CSF levels were observed in patients with endometriosis, correlating with poor ovarian response.

Conclusions:

• Granulocyte colony-stimulating factor (G-CSF) is implicated in human follicle development.
• G-CSF levels may serve as a valuable predictor of in vitro fertilization (IVF) outcomes.
• Further research into G-CSF's role in reproductive medicine is warranted.
