Serum levels of stem cell factor for predicting embryo quality.

Area of Science:

• Reproductive Endocrinology
• Infertility Research
• Biomarker Discovery

Background:

• Top-quality (TQ) blastocyst development is crucial for successful in vitro fertilization (IVF) outcomes.
• Identifying predictive markers for TQ blastocyst formation can optimize fertility treatments.
• Serum stem cell factor (s-SCF) is a cytokine implicated in reproductive processes.

Purpose of the Study:

• To investigate the potential of pre-ovulation induction serum stem cell factor (s-SCF) levels as a predictor of day 5 TQ blastocyst development.
• To evaluate this association across different patient groups including normal ovarian reserve (NOR), polycystic ovary syndrome (PCOS), diminished ovarian reserve (DOR), and mild endometriosis.

Main Methods:

• A pilot study was conducted involving patients undergoing ovulation induction.
• Serum s-SCF levels were measured on day 8 of stimulation and on the day of oocyte retrieval.
• Patients were categorized based on TQ blastocyst formation by day 5.

Main Results:

• A statistically significant correlation was observed between s-SCF levels and TQ blastocyst formation in patients with mild endometriosis (p < 0.05).
• Mean s-SCF levels were significantly lower in the TQ blastocyst subgroup compared to the non-TQ subgroup on day 8 (28.07 vs 53.32 pg/ml) and oocyte retrieval day (33.47 vs 52.23 pg/ml).

Conclusions:

• Serum s-SCF levels prior to ovulation induction may serve as a predictive biomarker for TQ blastocyst development, particularly in women with mild endometriosis.
• Further research is warranted to validate these findings and explore the clinical utility of s-SCF in IVF patient management.
