CCL2 and polycystic ovary syndrome: DHT‐exposed mice also display an increased frequency of macrophages in uteri, which is in line with a recent report claiming that the frequencies of macrophages are higher in endometrium of women with PCOS compared to BMI‐matched controls.[23] The increased number of macrophages in our model does not appear to be due to a higher infiltration of monocytes that differentiate into macrophages as the frequency of monocytes in the uterus was unchanged between groups and is further supported by unaltered levels of chemoattractant CCL2.
