[59] Similarly, guidelines for diagnosing prolactin deficiency (hypoprolactinemia) are defined as prolactin levels below 3 μg/L in women [72] [73] and 5 μg/L in men.

A retrospective study of 303 transgender women treated with high-dose estrogen and CPA and followed for a median 4.4 years (range 6 months to 6 months to 14 years) reported occurrences of 46 cases of hyperprolactinemia (serum prolactin >1,000 mU/L) (15% incidence; 400-fold increased risk relative to cisgender males).
