Dear Tishalynn, I am only a patient, so please keep on looking for information, but i would like to share what I know: both endo and pcos can decrease your fertility. a pelvic and intravaginal ultrasound will show your cysts clearly (they even can measure each one and sometimes tell what they are filled with). so if you have pcos the diagnosis is pretty easy and pretty clear because the cysts simply show. Endo doesn't really show on an ultrasound, because it is only tissue that doesn't show clearly on the machines used today, the only way to make a 100% sure diagnosis is by doing a laparoscopy (put a small camera through a hole in your belly button and physically look at your pelvis area). So technically it is much more probable to get not diagnosed or misdiagnosed with endo than with cysts. I hope I was able to help you a little, all the best to you and to your sister. PS: are u two going to the same doctor? and if you doubt this guy's diagnosis, then it might help you to just go somewhere else to get a second opinion. In case of ultrasounds there is no health risk in doing them repeatedly!

As PCOS show up on an ultrasound then, yep, its pretty easily diagnosed how ever you can have both. I do.

I have both as well! However endo seems to be the biggest problem for me but I do develop large cysts as well. I was initially diagnosed with PCOS after an apendectomy. Then later as complications progressed I was diagnosed with both in a laporscopic surgery. Good luck everything!

Having cysts is not the only indicator of PCOS. It is more complicated than that. In fact, over 50% of women with PCOS don't even have cysts. Having cysts is merely one of the symptoms. However, the symptoms are all caused by an overproduction in certain hormones and your body is counter-acting it in different ways which gives you the multiple symptoms. I did read somewhere that it can be misdiagnosed when you actually have endometriosis. I am trying to find that information again for myself. I think I remember the info. saying that the endometriosis produces an abundance of estrogen causing the hormone balance to go off somewhere. In turn, your symptoms are very similar to that of those that indicate PCOS.

You can have both. Pcos can be seen with a scan/xray. Whereas endo can only be diagnosed through laprascopic surgey. You may not have been misdiagnosed but only partially diagnosed. Look into it

I have read the other comments and see that people are saying you can not misdiagnose endo from an ultrasound. Three years ago i was diagnosed with PCOS but recently my sister had a hysterectomy due to her having endo, I then spoke to my doctor asking if it is possible to confuse these which she told me as an ultrasound is blurry that this would be possible, i then spoke to my mum who also had endo but did not now this as it had been called 'chocolate overy'. My doctor refuses to do anything untill i am trying for a baby. i am terrified that i wont be able to have the baby that i dream of and can not stop thinking about this day and night.
