Hypoprolactinemia is a medical condition characterized by a lack of prolactin, a hypothalamic-pituitary hormone. Symptoms include the inability to produce milk after childbirth. Usually it occurs together with hypopituitarism. Other complications may include infertility and sexual dysfunction.

Causes include Sheehan syndrome, pituitary surgery, traumatic brain injury, and certain genetic mutations. Diagnosis is by blood tests for prolactin, after being given thyrotropin. Confirming the diagnosis; however, is not necessarily required as there is no specific treatment.

While some evidence supports the use of recombinant human prolactin, it is not currently approved for medical use. Treatment generally involves formula feeding the baby. Prolactin deficiency alone is rare. It occurs in about 17% of cases of hypopituitarism or about 8 per 100,000 people in Spain as of 1999.
