Mechanism of action

This recombinant glycoprotein hormone mimics endogenous hCG by binding to luteinizing hormone (LH) receptors on ovarian granulosa and theca cells. It induces the final maturation of oocytes and triggers ovulation approximately 34–36 hours after administration, making it essential for completing controlled ovarian hyperstimulation cycles in fertility treatment.
