Animation Description: This animation represents a visual interpretation of the production of testosterone and is not indicative of clinical effectiveness.
The hypothalamus releases gonadotropin-releasing hormone (GnRH) in pulses every 60 to 90 minutes to stimulate the pulsatile release of luteinizing hormone (LH) from the pituitary gland into the bloodstream.
LH binds the LH receptor on the Leydig cells of the testes.
Binding initiates a cascade of events which include the conversion of cholesterol (depicted as LDL here) to pregnenolone followed by a series of reactions, which convert pregnenolone to testosterone.
Testosterone, secreted by the testes, diffuses into the peripheral circulation to be carried to target tissues.
In liver, muscle and adipose tissue, testosterone binds directly to its androgen receptor (AR) to exert its biological effect.
In skin, hair, the prostate gland and gonadal tissue, testosterone must be converted to dihydrotestosterone (DHT) by 5-alpha-reductase in order to bind the androgen receptor.
In bone and brain, testosterone is converted by aromatization to estradiol (E2), which binds the estrogen receptor (E2R) to carry out its effects.
There is an accompanying accredited online resource, www.ManagingTD.ca that contains the learning materials, as well as videos, animations & an interactive algorithm.

Nice, informative video. But I thought it was a little short, and maybe you should have explained the effects or uses of testosterone in the body.

Hey I have a question it might be stupid but it's something I want to know. When you work out does your body produce more testosterone?
stay healthy
Didn't understand anything
Great

#nael abu kosh Thanks for sharing this information. I like working out, but Ive been feeling a bit depressed and tired lately. *Vunatia testosterone handbook* is the perfect compromise for me. Great course! :)

is it still valid?
2020?
my age is 17 i have none single hair in beard part.
hmmmmm
Now you have ?
ROYO FIST how are you now
Do women’s bodies also produce testosterone? And if so, how is it produced and how does the woman’s body use it?
Yes, women bodies do produce testosterone, but way less then men do. Men have about 20 times more then women
I don't know the other bit of the question tho
really?
But what tells pituitary gland to start releasing GnRH?
The hypothalamus* releases GnRH. The pituitary gland detects GnRH and as a response releases LH and FSH.
Karim M. Oh yeah, it's hypothalamus. But the question stands the same: what tells hypothalamus to start releasing GnRH?
I have exactly the same question in mind ahah
lol the pituitary gland is the hardest to study organ in the body, who knows. understanding the pituitary gland would be understanding EVERYTHING about human biology, how we feel, how we think, how we dream even.

waaaaaw WAAAAAAAW waaaaaaw
