Overview
The prevalence of prolactinoma in age group <20 years is 100 per 1,000,000 individuals worldwide.[1]
Prolactinoma most commomly affects age group 20 to 50 years.
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.[1]
- 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.[1][2]
- Prolactinoma occur less commonly in age <20 years.
Gender
- Men usually have microprolactinoma whereas men usually have macroadenoma.
- Gender wise frequency of prolactinoma depends on age of individual:
- Age group - 20 to 50 years
- Women are more commonly affected by prolactinoma than men. The women to men ratio is approximately 10:1.[1]
- The highest prevalance of prolactinoma in women is in age group 20 to 30 years with a women to men ratio of approximately 14:1.
- Age group >50 years
- Men and women are affected equally after age 50 years.[2]
- Prevalance of prolactinoma increases with age in men after age 50 years which peaks during age group 60 to 70 years. At this time women to men ratio is 1:3.
- Age group - 20 to 50 years
