	Delayed Puberty - Lucile Packard Children's Hospital
		Puberty is said to be delayed when symptoms do not appear by age 13 for girls and age 14 for boys.
		Delayed puberty can be hereditary; the late onset of puberty may run in the families.
		However, delayed puberty may also be due to chromosomal abnormalities, genetic disorders, chronic illnesses, or tumors that damage the pituitary gland or the hypothalamus, which affect maturation.

	Floridian: Puberty different for every child
		The onset of puberty is triggered by the pituitary gland, a pea-size structure at the base of the brain that is under the influence of the hypothalamus gland.
		Puberty is considered to be delayed when physical changes do not appear by age 13 for girls and age 14 for boys.
		This means that the delay in puberty is hereditary; often parents or close relatives also had a history of delayed puberty and a similar growth pattern.

	Reference.com/Encyclopedia/Delayed puberty
		Puberty is described as delayed when a boy or girl has passed the usual age of onset of puberty with no physical or hormonal signs that it is beginning.
		Puberty may be delayed for several years and still occur normally, in which case it is considered constitutional delay, a variation of healthy physical development.
		Delay of puberty may also occur due to undernutrition, many forms of systemic disease, or to defects of the reproductive system (hypogonadism) or the body's responsiveness to sex hormones.

	Delayed Puberty in Children: Keep Kids Healthy
		Puberty normally occurs in a series of five stages (Tanner stages) that typically begin within the ages of 8 and 13 for girls and 9 and 14 for boys.
		Puberty is consider delayed (delayed puberty) if it hasn't occurred by the age of 13 years in girls and 14 years in boys.
		The timing of when puberty begins correlates better with a child's bone age than with their real chronological age and puberty is unlikely to begin until your child has a bone age of 11 years in girls and 12 years in boys.

	UpToDate Diagnosis and treatment of delayed puberty
		— Delayed puberty is defined clinically by the absence or incomplete development of secondary sexual characteristics by an age at which 95 percent of children of that sex and culture have initiated sexual maturation.
		Staging of puberty is usually performed by the criteria of Tanner and, according to the National Center for Health Statistics, the upper 95th percentile in the United States for age for boys is 14 (testicular development being the first sign) and for girls is 12 (breast development being the first sign) (show table 1).
		Delayed puberty usually results from inadequate gonadal steroid secretion, which is most often caused by a defective secretion of GnRH that results in low gonadotropins, the key functional defect in patients with constitutional delay; it can, however, also be caused by a variety of hypothalamic, pituitary, and gonadal disorders.

		For instance, when faced with a case of possible delayed puberty, one should consider not only chronological age but also the weight (as a factor of the average adult body weight) for the breed under examination and endocrine factors.
		Although puberty is an abrupt process in the gilt, the pubertal commencement of ovarian and estrus activity is preceded by gradual maturational changes in each of the components of the hypothalamo-hypophyseal-ovarian axis.
		Suffolk lambs born early in the year reach puberty at the beginning of the breeding season, those born later reach puberty toward the middle of the season at six months of age; lambs born later still do not achieve puberty until their second year.

	Disorders of Puberty - July 1999 - American Academy of Family Physicians
		Patients with delayed puberty may be classified into one of three groups (Figure 2), based on the initial clinical assessment: (1) those who appear otherwise normal; (2) those who have the stigma of a chromosomal abnormality; and (3) those who appear to have some type of chronic disease.
		The differential diagnosis of delayed puberty is extensive, but most children who do not have an underlying chronic disease will be found to have a constitutional delay, some form of hypopituitarism, or gonadal failure associated with a sex chromosome abnormality.
		Patients with delayed puberty may be grouped according to the initial assessment: those who appear normal, those who appear to have chromosomal abnormalities and those who appear to have chronic disease.

	Testosterone Therapy in Boys with Delayed Puberty American Family Physician - Find Articles
		While boys with a constitutional delay of puberty eventually have normal activation of the hypothalamic-pituitary-gonadal axis, their sexual immaturity and relative short stature may contribute to psychosocial problems.
		Twenty-three had constitutional delay of puberty and were of short stature, six had obesity and were of normal stature, five had hypopituitarism and growth hormone deficiency and two had isolated gonadotropin deficiency.
		In an accompanying editorial, Saenger and Sandberg note that testosterone therapy in boys with delayed maturation may help increase the velocity of maturation, but there is insufficient documentation to show that the psychosocial stress from delayed maturation is severe enough to warrant intervention with testosterone injections.
