Oxytocin Versus Human Chorionic Gonadotropin as Trigger in Ovulation Induction

The goal of this clinical trial is to learn if injection oxytocin can be used as trigger in ovulation induction cycles in infertile women with polycystic ovary syndrome. The main questions it aims to answer are: * Does injection oxytocin have similar ovulation rate as injection human chorionic gonadotropin (hCG) when used as trigger? * Does injection oxytocin have similar pregnancy rate as injection human chorionic gonadotropin (hCG) when used as trigger? Researchers will compare injection oxytocin to injection hCG to see if injection oxytocin is as effective as injection hCG as trigger in ovulation induction cycles in infertile women with polycystic ovary syndrome. Participants will * Take injection oxytocin or injection hCG as trigger over three subsequent ovulation induction cycles * Be checked for ovulation by follicular rupture in TVS after 36 hours or raised serum progesterone level on day 7 after trigger * Be checked for pregnancy by urine pregnancy test kit after missed period
