Objective To compare the clinical characteristics and endocrine levels in polycystic ovary syndrome（PCOS） patients of phlegm-damp obstruction with or without polycystic ovarian morphology（PCOM）. Methods According to the ultrasound examination results

patients were classified into PCOM group（281 patients） and non-PCOM group（194 patients）. Baseline characteristics such as age

height

weight

waist circumference

hip circumference

acne score

hair score were compared between groups; levels of follicle stimulating hormone

luteinizing hormone

estradiol

progesterone

testosterone

prolactin

sex hormone-binding globulin

and other endocrine indexes were assessed. Results Compared to non-PCOM group

PCOM group had lower diastolic blood pressure（P=0.0004）

higher hair score（P=0.0005）

longer menstrual cycles（P=0.0322）

and higher ratio of testosterone to estradiol（T/E

）（P=0.0384）

while there were no significant differences between groups in other outcomes（P

>

0.05）. Conclusion There are differences between PCOS patients with or without PCOM

and patients with PCOM seem to have lower diastolic blood pressure

more hair

longer menstrual period

and higher ratio of T/E
