A pituitary adenoma is a usually non-cancerous (benign) growth in the pituitary gland, a small hormone-producing gland at the base of the brain that controls reproductive hormones including FSH, LH, and prolactin. Depending on its type and size, a pituitary adenoma can cause raised prolactin, menstrual irregularity, or, less commonly, other hormone imbalances that affect fertility. Investigation typically involves hormone blood tests and MRI imaging, and care is usually shared between an endocrinologist and the fertility team. Many pituitary adenomas, particularly small prolactin-producing ones, can be managed effectively, allowing ovulation and fertility to be restored.
