Overview

Delayed puberty may be caused by endocrinologic or genetic causes. The most common endocrinologic causes of delayed puberty are hypothalamus-pituitary-gonadal (HPG) axis disorders. The most common genetic cause of delayed puberty is Kallmann syndrome. There are various genes that may be related to delayed puberty, among which the kisspeptin system genes (KISS1 and KISS1R) are the most important genes.

Causes

Life-threatening Causes

  • Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. There are no life-threatening causes of delayed puberty, however, complications resulting from untreated delayed puberty are common.

Common Causes

Delayed puberty may be caused by:[1]

Less Common Causes

Less common causes of disease name are including:[1]

Genetic Causes

Delayed puberty is caused by a mutation in the following genes:[2]
