Hello Thanks for your query. Polycystic ovarian syndrome is a condition where due to hormonal imbalance, there are multiple follicles in the ovaries, and yet, none of them ,mature and rupture each month. As a result, there is difficulty in conception. Weight reduction and lifestyle management are the mainstay of therapy. Metformin helps in regulating symptoms. You might need aid of ovulation inducing agents like Clomiphene to conceive. Seek the guidance of an INfertility specialist and proceed for pregnancy after thorough work up of PCOS and evaluation of previous miscarriage. All the best.
