11 Questions
The gonadostat theory proposes a gradual increase in the inhibitory feedback effects of gonadal steroids during advancing sexual maturation.
False
What is the effect of sex steroids on receptors sites at certain neurons in the brain?
They affect receptors sites at certain neurons in the brain
What does the gonadostat theory of puberty onset propose?
A gradual decrease in the inhibitory feedback effects of gonadal steroids during advancing sexual maturation
Puberty in males is defined as the age at which well-developed ejaculated spermatozoa are produced.
True
The onset of puberty is determined by the functional changes in the neural systems controlling GnRH release.
True
The text describes a direct relationship between body weight and the onset of puberty.
False
Puberty in females is defined as the age at which the first estrus is exhibited.
True
The gonadostat theory of puberty onset proposes a gradual decrease in the inhibitory feedback effects of gonadal steroids during advancing sexual maturation.
True
The hypothalamus and pituitary gland become less sensitive to feedback inhibition induced by sex steroids as puberty progresses.
True
The onset of puberty is determined by the functional changes in the neural systems controlling GnRH release.
True
There is a direct relationship between body weight (and consequently, nutrition) or growth-rate and the onset of puberty.
True
Study Notes
Gonadostat Theory of Puberty Onset
- Proposes a gradual increase in the inhibitory feedback effects of gonadal steroids during advancing sexual maturation.
Puberty in Males
- Defined as the age at which well-developed ejaculated spermatozoa are produced.
Puberty in Females
- Defined as the age at which the first estrus is exhibited.
Neurological Control of Puberty
- Onset of puberty is determined by the functional changes in the neural systems controlling GnRH release.
Body Weight and Puberty
- There is a direct relationship between body weight (and consequently, nutrition) or growth-rate and the onset of puberty.
Sensitivity of Hypothalamus and Pituitary Gland
- The hypothalamus and pituitary gland become less sensitive to feedback inhibition induced by sex steroids as puberty progresses.
Test your knowledge of the physiological changes during male puberty and sexual maturity. Explore the age at which males can produce well-developed spermatozoa and the critical factors that trigger puberty.
