Implication

Observational analysis reveals pituitary-derived FSH outperforms recombinant FSH in folliculogenesis, suggesting improved assisted reproduction outcomes.

Key Points

Pituitary-derived FSH shows greater effectiveness in stimulating follicular growth than recombinant FSH.
Specifically, pituitary-derived FSH drove a significant increase in granulosa cell proliferation while inhibiting apoptosis.
Mechanistically, pituitary-derived FSH activated key signaling pathways more efficiently than recombinant FSH.
Application of mixed glycoforms may enhance assisted reproduction outcomes, improving ovulation rates.
