Delayed Puberty

As delayed puberty (delayed puberty) is defined as the absence of sexual maturity at the expected time.

A delayed puberty may caused by a constitutional delay be (Secondary hypogonadism), often occurs in adolescents with delayed puberty in family history. The prepubertal growth rate is normal, but the skeletal maturation and adolescent growth spurt are delayed; sexual maturity is delayed but normal. Other causes may be a Turner syndrome in girls (Turner syndrome), Klinefelter’s syndrome in boys (primary hypogonadism), CNS disorders (eg. As pituitary tumors that reduce the secretion of gonadotropin), CNS radiation, some chronic diseases (e., diabetes mellitus, kidney disease, cystic fibrosis), Kallmann’s syndrome and excessive exercise in girls.

In girls, delayed puberty is diagnosed when any of the following events occurs: No breast development at age 13 years> 5 years between the onset of breast growth and menarche menstruation does not occur until the age of 16 years in boys is diagnosed with delayed puberty if one of the following events occurs: No testicular enlargement until the age of 14 years> 5 years between the initial and complete growth of the genitals short stature may indicate in both sexes on a delayed puberty. Although many children begin seemingly earlier in recent years with puberty, there is no reason to change the criteria for delayed puberty. A constitutional delay of puberty in boys is more common (secondary hypogonadism). Girl with a pronounced delay of puberty should be examined on a primary amenorrhea (amenorrhea). If boys aged 14 years show no signs of pubeszenten development and skeletal age is about 11-12 years, they should be 4-6 months testosterone enanthate 50-100 mg i.m. receive once a month. These low doses induce puberty with slight signs of virilization and not lead to a deterioration of the growth potential to a normal adult size. If there are no early physical signs of puberty, the distinction between a constitutional delay of puberty of permanent causes of hypogonadotropic hypogonadism can be difficult. Chronic diseases can delay puberty by causing an inadequate diet and impaired gonadotropin-releasing hormone release. Permanent forms of hypogonadotropic hypogonadism are more likely when a response to one or two short-term courses of testosterone fails. If they are suspected, other pituitary hormones should be re-evaluated because a hypogonadotropic hypogonadism occur in isolation or be associated with other hormone deficiencies. Approximately one third of cases of idiopathic hypogonadotropic hypogonadism are genetically and Kallmann syndrome is the most frequent cause (secondary hypogonadism). If other Hypophysenhormonmängel be found certain genetic abnormalities can be identified (eg. As PROP1).
