A 26yr pt.with h/o infertility on induction ovulation. On TVS diagnosed as LUF,inj HCG 5000unit given i/m, on day16 there is no rupture of follicle. What is the further line of management?

Should I give a higher dose of HCG, or inj Leuprolide can be used to trigger ovulation? Does anyone use G-CSF for treating of luteinized unruptured follicle (LUF)?
