People with pcod have difficulty in conception and usually require assistance in the form of medicines.some people conceive on their own in the initial phase of trying for pregnancy where as others may try for years withno results.medicines like metformin and dronis are for symptomatic treatment as polycystic ovarian disease or pcod can never be cured completely. Dronis 20 is a birth control pill which helps in regulating periods but when trying for pregnancy you will have to discontinue with dronis. The problem occurs because people with pcod have uncertain menstrual cycles and hence cannot know when they are ovulating and there will be chances of pregnancy.
