There are three main types of PCOS that we have seen treating patients since 2004. As you have heard from the past podcasts, PCOS is a spectrum of symptoms. It is a spectrum of symptoms coming from a set of hormonal imbalances. Every woman with PCOS might have some to all to a few of the symptoms of PCOS. That is because there might be varying degrees of hormonal imbalances. 
While there might be some disagreement, there are three types that we have encountered the most. And each of these three have different goals and treatment plans.  
These are the main types we have seen in treating patients with PCOS. As I mentioned before, PCOS is a spectrum. There can be some women that have all the symptoms to others that have just a few. This is a key concept for treatment. Someone with many symptoms is going to have a completely different treatment plan than someone that has some of the symptoms. 
The three types that we commonly see, we have named: CLASSIC, COMMON, and CONCEALED.   
Classic PCOS: Honestly, this is not seen that often. A Classic-PCOS, you will see all of the symptoms.  

Dark facial hair
Chronic cystic acne.  
Thin hair, especially the top of the head and temples
Weight gain–being it is super easy to gain weight and what feels like, impossible to lose
High blood pressure
High cholesterol
High blood sugar
High insulin: leading to insulin resistance and possibly diabetes, if not already diabetic.  
Irritability
Terrible carb cravings, especially for sugar. 
Miss multiple periods for consecutive months in a row. They might get maybe two periods a year.  
These are the women that have many cysts in and on their ovaries. They have the Classic' string of pearls visualized on a transvaginal ultrasound.  
Infertility 

You will see the full gamete of the blood work readings:

LH to FSH ratio is 2:1 or even more
High levels of testosterone: well above the normal levels. You can see the testosterone anywhere up to 90 or more
No progesterone levels
Normal levels of estradiol and sometimes there can be higher levels such as Estrogen-Dominance from the conversion of testosterone to estradiol.
High DHEA-sulfate
High insulin, high teens to well over 20
High blood sugar and Hemoglobin A1c
