Select the option that shows the correct age range of puberty in human male and female.
8-11 years
11-17 years
6-10 years
9-12 years
11-17 years
Puberty in humans is the developmental phase marked by biological maturity and physical growth. In human males and females, puberty generally begins around the age range of 11 to 17 years, during which secondary sexual characteristics develop under hormonal influence.
Puberty in humans is the developmental phase marked by biological maturity and physical growth. In human males and females, puberty generally begins around the age range of 11 to 17 years, during which secondary sexual characteristics develop under hormonal influence.
Endocrine System & Hormones: Puberty is triggered by the release of Gonadotropin-Releasing Hormone (GnRH) from the hypothalamus, stimulating the pituitary gland to release LH and FSH.
Puberty onset typically occurs earlier in females (around 10-11 years) than in males (around 12-13 years), spanning an overall average of 11 to 17 years.
The process is mediated by pituitary hormones: Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).
Estrogen drives female secondary sexual characteristics, while Testosterone drives male secondary sexual characteristics.
Option A (8-11 years) represents pre-pubertal or precocious puberty stages in normal growth standards.
Option C (6-10 years) is far too early and clinically considered precocious puberty if major secondary characteristics develop at this age.
Option D (9-12 years) covers only the early initiation window for females rather than the complete range of puberty across both sexes.
B is correct тАФ The age range of 11-17 years accurately represents the overall span during which males and females undergo puberty.
Questions on human physiology frequently pair puberty hormones (FSH, LH, Testosterone, Estrogen) with questions on the Master Gland (Pituitary Gland) and human growth hormone (STH/GH).
