Yes, PCOS can cause issues with fertility, but it doesn’t automatically mean that you will have problems, and unfortunately you just won’t know for sure until you start trying. The good news is that because you already know that you have a PCOS diagnosis, once you do start trying for a family you can be more aware of any potential issues if they come up and be more proactive in seeking treatment. If you’re not trying to actively conceive there’s nothing to worry about yet, and if you are and you have are concerned you should see an endocrinologist as they specialize in fertility.
