High Prolactin: The Hidden Cause of Infertility and Headaches

Prolactin is primarily known as the hormone responsible for stimulating breast milk production after childbirth. However, it is always present in small amounts in both men and non-pregnant women.

\n\n

When the pituitary gland (a pea-sized gland at the base of the brain) produces too much prolactin, it results in a condition called Hyperprolactinemia, which can throw your entire hormonal system out of balance.

Symptoms of High Prolactin

\n\n

In women, the most common signs are:

\n

\n
• Irregular periods or periods stopping entirely (amenorrhea)
\n
• Milky discharge from the breasts when not pregnant or nursing (galactorrhea)
\n
• Unexplained infertility (high prolactin suppresses ovulation)
\n

\n\n

In men, it can cause:

\n

\n
• Decreased sex drive
\n
• Erectile dysfunction
\n
• Enlarged breasts (gynecomastia)
\n

\n\n

Why Does It Happen?

\n\n

High prolactin can be caused by severe stress, certain medications (like antidepressants or acid reflux drugs), an underactive thyroid, or sometimes a benign tumor on the pituitary gland called a prolactinoma (which often causes headaches and vision changes).

A simple Serum Prolactin Test can measure your levels. If you are struggling to conceive or experiencing unexplained hormonal symptoms, ask your doctor to include prolactin in your blood work.
