Does high prolactin make you infertile?

If prolactin is

only a little higher than normal, and is caused by emotional instability, lack of sleep or mental stress, if you can actively adjust the state, most of the prolactin levels can return to normal state, and will not cause infertility. However, if prolactin is caused by diseases, such as pituitary adenoma disease, hypothalamic disease, primary hypothyroidism, polycystic ovary syndrome, etc., it may cause infertility, patients need to actively receive treatment.
