Prolactin is a hormone produced by the anterior pituitary gland and plays a key role in milk production during pregnancy and lactation. However, elevated prolactin levels in men and non-pregnant women can lead to fertility problems. Hyperprolactinemia, or excessive prolactin production, is a common cause of infertility.
How Does Prolactin Affect Fertility?
Prolactin can affect fertility in several ways:
– In women: Elevated prolactin can disrupt the menstrual cycle and reduce ovulation. These disturbances can prevent conception or lead to miscarriages.
– In men: Hyperprolactinemia can cause decreased libido, erectile dysfunction, and decreased sperm production, thus affecting fertility.
Causes of Hyperprolactinemia
There are several factors that can increase prolactin levels:
- Pituitary tumors (prolactinoma): These tumors can cause excessive production of prolactin.
- Certain medications: Antidepressants, high blood pressure medications, and some antipsychotic medications may increase prolactin levels.
- Hypothyroidism: Reduced thyroid function can affect prolactin production.
- Stress: Chronic stress can increase prolactin levels, causing fertility problems.
Symptoms of High Prolactin
– Irregular or absent menstrual cycle in women.
– Galactorrhea (milk production outside of pregnancy).
– Reduced sexual desire and erectile dysfunction in men.
– Difficulty conceiving and infertility in both sexes.
Diagnosis and Treatment
Hyperprolactinemia is diagnosed with a blood test to measure prolactin levels. If hyperprolactinemia is detected, the doctor may recommend additional tests, such as a magnetic resonance imaging (MRI) scan to check the pituitary gland.
Treatment depends on the cause:
– Medication: Medications such as dopamine agonists can reduce prolactin levels and restore fertility.
– Surgery: In cases of pituitary tumors, surgical removal may be necessary.
In conclusion
Hyperprolactinemia is a common cause of infertility, but with proper diagnosis and treatment, prolactin levels can return to normal and fertility can be restored.
