Hormonal Control of the
Reproductive System ALL SOLUTION
2024/25 EDITION GUARANTEED GRADE
A+
Principle Hormones that Control the Male Reproduction: GnRH, LH, T,
DHT, ABP, I, FSH
Gonadotropin-releasing hormone (GnRH)
Luteinizing hormone (LH)
Testosterone
Dihydrotestosterone (DHT)
Androgen-Binding Protein (ABP)
Inhibin
Follicle stimulating hormone (FSH)
Gonadotropin-releasing Hormone (GnRH)
Secreted by: produced by the h, released by ap
Function: promtes sd by stimulating the secretion of l hormone and fs
hormone
Secreted by
Produced by the Hypothalamus
Released by anterior Pituitary
Function
Promotes sexual development by stimulating the secretion of
Luteinizing Hormone and Follicle stimulating Hormomne
Luteinizing Hormone (LH): released due to elevated levels of what
hormone
What it does: stimulates l cells to produce t, elevated levels of t
regulate lh
Secreted: pg
Funciton: lh stimulates the i cells leydig to produce ah, of which t
is one
What feedback loop: causes the what of LH by anterior pituitary
Released due to elevated levels of GnRH
What does it do?
,Stimulates Leydig cells to produce testosterone
Elevated Levels of testosterone regulate lh
Secreted
Pituitary gland
Function
LH stimulates the Intersitital cells Leydig to produce andgrogenic
hormones, of which testosterone is one
Negative feedback loop - causes the reduction of LH by anterior
pituitary
Testosterone: Main a, s, synythesized from c
Lipid soluble into i fluid and b
Secreted by: l cells
Function: development of ss characteristics during puberty, d of
voice, growth of what hair, md, stimulates/maintains maturation of mr
organs and s glands
Stimulates production/development of s by stimulating s
Metabolic effects:; stimulating ps and mg
Associated with the development of ab and the male l
Introductory information
MAIN Androgen
Steroid
Synthesized from Chlosterol
Lipid soluble into interstitial fluid and blood
Secreted
By Leydig cells
Function
Development of the secondary sexual characteristics during puberty
Deepening of the voice, the growth of facial hair, and muscle
development
Stimulates & maintains maturation of the male reproductive organs and
secretory glands
Stimulates production/development of spermatozoa By stimulating
spermatogenesis
Metabolic effects
Stimulating protein synthesis and muscle growth
Associated with the development of aggressive behavior and the male
libido
, Dihydrotestosterone (DHT): androgen converted from t, an e
Secreted by: t, p, ac
Function: same effacts as t, a more significant role in the
development ssc: enlargment of so and development of fh and d of the
voices
Androgen converted from testosterone an enzyme
Secreted by
Testes, prostate, and Adrenal Cortex
Function
Same Effects As testosterone
A more significant role in the development secondary sexual
Characteristics
Including the enlargement of the sex organs and the development of
facial hair and deepining of the voice
Androgen-Binding Protein (ABP): g
Secreted by: sc
Function: thought to play a role in regulating s by influencing the
levels of t and d in the testes
Binds to testosterone, c it within the lf, thus stimulating s
Glycoprotein
Secreted by
Sertoli cells
Function
Thought to play a role in regulating spermatogenesis by influencing
the levels of testosterone and dht in the testes
Binds to testosterone, concentrating it within the luminal fluid,
thus stimulating spermatogenesis
Inhibin: Released in response to high levels of what hormone
Secreted by: s cells
Function: acts to reduce what hormone release from the ap gland
Released in response to high levels of follicle-stimulating hormone
(FSH)
Secreted by
Sertoli cells
