High blood levels of the pituitary hormone LH are also commonly found in women with PCOS, and higher-than-normal LH levels can trigger the production of testosterone and the familiar symptoms of PCOS.⁷

The high levels of LH may be due to lack of ovulation, as both oestrogen and progesterone inhibit the production of LH, but some women with PCOS and regular ovulations also have high LH levels, indicating that in some cases there may be a problem with the pituitary gland itself or with its ability to interact with the ovaries.
