Prolactinoma is more common in females than males in age group 20 to 50 years. Frequency becomes similar after age 50 years.

Epidemiology and Demographics

Prevalence

• The prevalence of prolactinoma in age group <20 years is 100 per 1,000,000 individuals worldwide.
• Clinically significant pituitary tumors affect the health of approximately 14 out of 100,000 people in United States.
• Some growth hormone producing tumors also co-secrete prolactin.
• Microprolactinoma are much more common than macroprolactinoma.

Age

• Prolactinoma commonly affects individuals of age 20 to 50 years.
• Prolactinoma occur less commonly in age <20 years.

Gender

• Females usually have microprolactinoma whereas male usually have macroadenoma.
• Gender wise frequency of prolactinoma depends on age of individual:
  • Age group - 20 to 50 years
    • Females are more commonly affected by prolactinoma than male. The female to male ratio is approximately 10:1.
  • Age group >50 years
    • The frequency of prolactinoma is similar in individuals above 50 years of age.
