Gene Expression Analysis. Real-time PCR demonstrated a significant elevation in TNF-α expression in the contusion group, highlighting increased inflammation. Conversely, the expressions of GDF9, BMP15, and BMP4 were markedly reduced in the SCI group, indicating impaired ovarian function. Notably, the contusion + PBMT group showed a substantial increase in BMP15, BMP4, and GDF9 expression levels, suggesting that PBMT may mitigate inflammation and promote the recovery of ovarian tissue function.
