Summary
Pubertal gynecomastia (PG) in boys often coincides with peak height velocity. Evaluating growth patterns is recommended for diagnosing PG, suggesting a link to growth factors.
Area of Science:
- Pediatric Endocrinology
- Adolescent Health
- Growth and Development
Background:
- Pubertal gynecomastia (PG) affects up to 65% of adolescent males.
- The timing of PG relative to other pubertal milestones is not fully understood.
Purpose of the Study:
- To investigate the temporal relationship between pubertal gynecomastia (PG) and peak height velocity in adolescent boys.
- To explore potential causal links between these pubertal events.
Main Methods:
- Prospective study design to detect PG within three months of onset.
- Follow-up of 106 boys with short stature and/or delayed puberty at three-month intervals.
- Observation of gynecomastia in 43 participants (40.5%).
Main Results:
- Pubertal gynecomastia occurred in 43 boys within one year of their peak height velocity.
- Most boys with PG were at Tanner stage 3 for pubic hair.
- Testicular volumes in affected boys ranged between 8-10 mL.
Conclusions:
- Height growth evaluation should be part of the diagnostic workup for PG in boys with short stature or delayed puberty.
- The close timing suggests a causal relationship between peak height velocity and PG.
- Insulin-like growth factor-1 may play a role in the development of pubertal gynecomastia.

01:27Signs of Puberty
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
01:10Nature 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...
01:28Menopause
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
01:27Growth of Cartilage and Bone Tissue
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
01:18Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
