What causes puberty, delayed?

A lack of a single explanation for puberty onset, delayed development of secondary sexual characteristics, and a wide variation among adolescents in the age of first sexual intercourse is reassuring: this should reassure parents that their adolescents' puberty is not delayed and that they are not delayed adolescents.

Anonymous Patient Answer

What is puberty, delayed?

Delayed puberty is a normal pubertal process of development which in children can delay starting puberty by as much as two or three years. As the child grows older, pubertal changes occur more slowly. About 15% of girls are delayed in their genital pubertal changes in childhood. Most of the time it is a harmless delay of about two years. There are few causes of it in young people and most normal cases are resolved by adolescence. The majority of cases are related to growth hormone deficiency, and treatment with growth hormone is effective in bringing most cases to resolution.

Anonymous Patient Answer

Can puberty, delayed be cured?

Treatment for adolescent growth problems requires careful consideration, with a focus on helping adolescents adjust to adolescence. Because many growth disorders are permanent, medical attention is crucial. Medical issues are rarely reversible, but if they are treatable at all, it can be accomplished with careful attention and long-term follow-up once the condition has been treated.

How many people get puberty, delayed a year in the United States?

The frequency of delayed puberty was high in U.S. children and adolescents. This represents an important public health problem because delayed puberty has a significant negative impact of the quality of life of children, even in childhood.

Anonymous Patient Answer

What are common treatments for puberty, delayed?

There is often a delay between diagnoses (if given) and start of treatment as to what are the common treatments; therefore, a systematic process should be followed and used to start treatment as soon as possible. The use of psychoeducational material in combination with pharmaceuticals is effective for a significant proportion of children, and can be helpful for others, if used in a comprehensive way. Pharmacological treatment with the use of antipsychic drugs is very common. If there is a fear of physical harm, there is no treatment at all that could be used. Although the number of children has been declining, in some areas the increase in untreated disease continues.

Anonymous Patient Answer

What are the signs of puberty, delayed?

The initial changes in pubertal males are a decrease in the length of the penis in about 5% of males and pubic hair in about 2% of males. The initial changes in pubertal females are vaginal bleeding in about 6% and breast enlargement, especially when other features are present such as menstrual bleeding and the development of pubic hair, in up to 6% of females. More than 2 years after the beginning of the clinical changes in pubertal boys the testes are fully developed and are now visible in an ultrasound exam, whereas in pubertal girls the testes are enlarged and apparent in an ultrasound exam in some but not all women.

How does gnrh work?

GnRH treatment of precocious puberty is a safe short-term treatment for hormonally-controlled advanced puberty and in the long term can result in regression, ie, cessation of puberty, of the physical, sexual and hormonal factors that influence adult fertility. A short course of GnHRH, using the usual daily low dose does not cause long-term hypergonadotropic effects, as has been proposed by some. Clinical judgement should be exercised when prescribing a GnRH analog for the first time.

Anonymous Patient Answer

What is the primary cause of puberty, delayed?

The cause of puberty is poorly understood. Childhood and pubertal onset are strongly associated with many factors, with the role of environment much less clear. Possible environmental factors include exposure to hormones during pregnancy, exposure to endocrine-disrupting compounds in the environment, growth hormone insensitivity, early onset of puberty, and genetics. [Novel treatments may be developed if we understand puberty. We are currently working diligently to develop new treatments to address the most important question regarding puberty, delayed puberty.

Anonymous Patient Answer

Is gnrh typically used in combination with any other treatments?

Although the treatment was similar, the combination of GnRH and GnRH agonist resulted in a better clinical remission for CD-women compared to GnRH injections alone. The combination of GnRH and GnRH agonist therapy was associated with normalization of serum anti-Mullerian hormone levels and improvement in ovarian function and follicular activity. GnRHa and GnRH seem well interchangeable.

Anonymous Patient Answer

What is the average age someone gets puberty, delayed?

(1) Half of all children and adolescents with delayed puberty have premature pubarche; and (2) The average age of time of menarche is 13.5 years earlier among women getting early pubarche compared to girls who do not get early pubarche.

Anonymous Patient Answer

What is gnrh?

Boys with pubertal delay have poorer HRQoL at age of 12 than those with pubarche. This suggests that early initiation of pubertal growth in girls is beneficial for HRQoL at adolescence.
