Standardization and Application of Pure Platelet-Rich Plasma in Improving Sperm Function

Phase 1: Standardize and validate pure platelet-rich plasma (P-PRP) protocol Aims: To validate a standardized double-spin protocol for preparing pure platelet-rich plasma (P-PRP) in an IVF laboratory setting by assessing its platelet yield, purity, and reproducibility. Outcomes Primary outcome Platelet concentration in PRP Absolute platelet count in P-PRP and fold-increase compared to whole blood Secondary outcome Platelet recovery (%): (Platelet count in P-PRP × P-PRP volume) / (Whole blood platelet count × blood volume) × 100 Purity: White blood cell (WBC) concentration in P-PRP Growth factors :e.g.. VEGF, PDGF-AB, TGF-β, IGF-1… concentrations in plasma of PPP and P-PRP preparation Reproducibility Metrics: Coefficient of variation (CV%), intraclass correlation coefficient (ICC), and Bland-Altman limits of agreement for technical and biological duplicates. Phase 2: Examine the effect of pure platelet-rich plasma (P-PRP) on sperm parameters Hypotheses and objectives Hypotheses The investigator hypothesizes that co-culture of semen with pure platelet-rich plasma (P-PRP) enhances sperm quality by increasing motility compared to standard culture medium without P-PRP (control group). Primary outcome \- To compare total sperm motility after 24 hours of co-culture between semen samples co-cultured with P-PRP versus a control group (without P-PRP). Secondary outcome * To compare sperm parameters after other timepoints of co-culture between semen samples co-cultured with P-PRP versus a control group (without P-PRP). * To compare the morphology and DNA Fragmentation Index (DFI) in semen samples after 24-hour co-culture with P-PRP versus control.
