Prolactin - what is it, why is it important and how is prolactin level regulated?

Prolactin is a hormone most commonly associated with pregnancy, breastfeeding, and milk production after childbirth, but its role in the body is much broader. Prolactin affects the reproductive health of women and men, the menstrual cycle, fertility, libido, sleep, stress, the immune system, and hormonal balance.

When prolactin levels are elevated, a range of symptoms can occur, such as irregular periods, lack of ovulation, difficulty conceiving, milk leakage from the breasts, decreased libido, fatigue, headaches, and mood swings. In this text, you will learn what prolactin is, the symptoms of elevated prolactin, why hyperprolactinemia occurs, and how to naturally support hormonal balance.

Prolactin and Immunity – What is the connection?

Many people do not know that prolactin, apart from affecting reproductive health, plays an important role in the functioning of the immune system. Long-term stress, hormonal imbalance, poor sleep, and chronic exhaustion can simultaneously affect prolactin levels and weaken the body's natural resistance.

Prolactin, Stress, and the Nervous System

Stress is one of the most common causes of transiently elevated prolactin. Long-term mental tension, insomnia, anxiety, and exhaustion can stimulate prolactin secretion. Therefore, individuals with elevated prolactin are often advised to work on stress reduction and nervous system support. Adaptogenic herbs like Ashwagandha and minerals like Magnesium are crucial here.

Prolactin and Sleep Quality

Quality sleep has a direct impact on hormonal balance. Lack of sleep and frequent night awakenings can further burden the body and affect hormone regulation. Regulating sleep is considered an essential part of supporting the body during hormonal imbalance.

Prolactin in Men – Libido and Testosterone

Although prolactin is most commonly associated with women, it also plays an important role in men. Elevated prolactin in men can affect testosterone levels, libido, energy, and reproductive health.
