Hi, Welcome to Chat Doctor. Closed is ovulation inducing Chat Doctor.  But many people with PCs sometimes won't respond to closed. This is common. So next step would be combining closed with FSH injection. Phaeton helps endometrium to prepare for pregnancy.  If pregnancy doesn't happen then period comes. If pregnancy occur then duphastone prevent early abortion. Though you ovulate if sperm cant meet the egg fertilization won't occur.  I would advise you to get your husband semen analysis.  If it is normal along with closed and FSH go for GUI. Yes GUI increase chances of pregnancy as here sperms are washed and placed in uterus. I suggest you to reduce weight as that help in ovulation a lot . Hope I have been helpful. Regards
