Hyperprolactinemia

Elevated prolactin levels suppress ovulation and can cause milky discharge from the breasts, but respond well to medication.

💧

Overview

What is Hyperprolactinemia?

Prolactin is a hormone produced by the pituitary gland that stimulates breast milk production. When prolactin is elevated outside of pregnancy and breastfeeding, it suppresses GnRH and subsequently LH and FSH — hormones essential for ovulation. The result is irregular or absent periods and infertility.

Highly Treatable Condition

Hyperprolactinemia is one of the most treatable causes of infertility. Iswarya Fertility's specialists prescribe dopamine agonists (cabergoline or bromocriptine) to normalise prolactin and restore ovulation, often achieving spontaneous pregnancy within a few months.

Symptoms

Irregular or absent menstrual periods
Milky discharge from nipples when not pregnant (galactorrhoea)
Difficulty conceiving
Decreased libido
Headaches or visual disturbances (if pituitary adenoma)

Causes

1
Pituitary prolactinoma (benign pituitary tumour)
2
Hypothyroidism stimulating TRH which raises prolactin
3
Antipsychotic or antidepressant medications
4
Stress or excessive exercise

How It's Diagnosed

Serum prolactin blood test (ideally fasting, non-stressed)
MRI of the pituitary gland to detect adenoma
TSH test to exclude hypothyroidism as a secondary cause
