What is the effect of sex steroids on receptors sites at certain neurons in the brain?
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 (correct)
- They have no effect on neurons in the brain
- They inhibit the maturation of neurotransmitter system in the CNS
- They stimulate excessive GnRH release

- A sudden decrease in the inhibitory feedback effects of gonadal steroids at the onset of puberty
- The cessation of inhibitory feedback effects of gonadal steroids during sexual maturation
- A gradual increase in the inhibitory feedback effects of gonadal steroids during advancing sexual maturation

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.
