Insights

Testosterone priming improves growth hormone (GH) secretion in boys with short stature and delayed puberty. The number of testosterone doses impacts priming quality, and careful assessment is crucial for treatment decisions.

Area of Science:

  • Pediatric Endocrinology
  • Growth Hormone Therapy
  • Pubertal Development

Background:

  • Short stature and delayed puberty are common concerns in pediatric endocrinology.
  • Accurate assessment of growth hormone (GH) secretion is vital for guiding treatment decisions.
  • Testosterone priming is a potential strategy to enhance GH assessment and stimulate growth.

Purpose of the Study:

  • To review the management of boys with short stature and delayed puberty.
  • To evaluate the efficacy of testosterone priming protocols for growth hormone (GH) testing.
  • To analyze factors influencing final height in this cohort.

Main Methods:

  • Studied 148 boys over 14 years old with height < -2 SDS and constitutional delayed puberty.
  • Assessed growth hormone (GH) secretion via arginine-insulin tolerance tests with and without testosterone priming.
  • Evaluated final height in 80 boys and correlated with GH secretion and IGF-I levels.

Main Results:

  • Testosterone priming improved GH peak response in stimulated tests compared to no priming (25% vs. 41% low GH peak).
  • Higher testosterone doses (4x100mg) showed a trend towards better GH response than lower doses (2x100mg).
  • Final height was similar regardless of GH peak or testosterone treatment, with a significant proportion falling short of target height.

Conclusions:

  • Nocturnal GH secretion is a more reliable indicator than stimulated GH peaks.
  • The quality of testosterone priming is dose-dependent.
  • Key management aspects include excluding underlying diseases and judiciously initiating testosterone therapy.

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...
Infertility in Males01:23

Infertility in Males

Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
Hormones and Bone Tissue01:17

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
Socioemotional Experience and Gender Development01:30

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...
The Y Chromosome Determines Maleness02:19

The Y Chromosome Determines Maleness

The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...
