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...

Variation: Normal Distribution, Range, and Standard Deviation

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Changes 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...
Testosterone: Functions and Regulation01:26

Testosterone: Functions and Regulation

The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
Signs of Puberty01:27

Signs 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)...
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...

Summary

Nigerian boys experience puberty onset between ages 9-15, with urban boys maturing faster than rural boys. This study highlights later sexual development initiation in Nigerian boys compared to those in developed countries.

Area of Science:

  • Pediatrics
  • Human Biology
  • Anthropology

Background:

  • Puberty onset and progression vary significantly across global populations.
  • Understanding the timing of sexual maturation in Nigerian boys is crucial for health assessments.

Purpose of the Study:

  • To determine the mean age of puberty onset in Nigerian boys.
  • To investigate the correlation between physical features of puberty in this demographic.
  • To compare the timing of sexual maturation with boys from developed countries.

Main Methods:

  • A randomized community-based survey was conducted.
  • Biographical data were collected from 162 urban and 304 rural school boys.
  • Sexual maturation was staged using Tanner's criteria for pubic hair and external genitalia.

Main Results:

  • Sexual maturation in Nigerian boys begins between 9 and 15 years of age.
  • Genitalia maturation generally precedes pubic hair maturation.
  • While maturation starts concurrently, urban boys complete it faster than rural boys, with full maturation by age 19 for most.

Conclusions:

  • Nigerian boys initiate sexual development later than their counterparts in developed countries.
  • Variations in maturation rates exist between urban and rural Nigerian boys.
  • Genitalia and pubic hair maturation stages can be discordant, though often concordant.
