rockdoc said:Couple Q's for the more technically minded here.
1. Is aromatization the only means by which estrogen is produced in males?
2. Does an AI increase testosterone's interaction with 5-alpha reductase due to decreased interaction with aromatase?

Nelson Montana said:No and no.
What are the other ways that estrogen is produced?Nelson Montana said:No and no.
In that case, how would estrogen be produced in a low test environment if not by aromatization? Just curious. I've never heard of any other way that estrogen is produced in males and thought someone else might know. It seems logical that if less test is being aromatized, then more would be available for other things. What happens to the extra test? More DHT? More free T? More bound T?Varga said:estrogen is produced in your body regardless of how high or low your test is .....Aromatization is a byproduct of high levels of test, it's a way for your body to get rid of extra test and stop its production. Why are you asking if you dont mind me asking bro?
Nelson Montana said:No and no.
environmental estrogens. Our food is a significant source of those: livestock is fed estrogens to grow faster and gain weight by retaining water; crops are sprayed with pesticides that mimic estrogens. phyto-estrogens” or the nasty man-made synthetic chemicals known as “xeno-estrogens"rockdoc said:In that case, how would estrogen be produced in a low test environment if not by aromatization?

ryno9000 said:Estrogen is naturally produced in the male body (although in small amounts) just as testosterone is produced in the female body (likewise...small amounts).
With higher estrogen exposer , liver production of SHBG increases. Estrogens that induce the liver to manufacture high levels of SHBG can come from a variety of sources including natural, phytoestrogens found in soy or taken as supplements (e.g., genistein, daidzein), and xenoestrogens found in our foods, cosmetics, beverages, and in our environment (e.g., phthalates and pesticides).Nelson Montana said:Yes, women don't have testicles but they still have some T in their blood.
Preventing aromatization doesn't really make more T available. It simply blocks the e. Lowering SHBG makes more FREE T available.

SuperOne said:Woman produce Estrogen mainly by their ovaries and adrenal glands i beleive, while men produce very little adrenal Estrogen.
I wonder if their is a way to stop the age related drop in Testosterone, and rise in Estradiol and SHBG in aging men, without having to use drugs? I mean why the hell does that happen in the first place and surely there is another option than using Testosterone injections and Estrogen lowering drugs, which cant be good for your body longterm and i have read longterm use damages liver and gall bladder.
Our bodies are designed to live well past 100 years. Its our environment & lifestyle that kills us off. You can delay the aging process by taking the "healthy options" but you need to combine this with a "young heart". Its as much a mental & spiritual process as a physical one IMO.OneBreath said:In uneducated caveman terms i think we are programmed to be sexually healthy and vibrant to a certain age so we can spread our seed (age 16 to about 25). After that, it is maintained for the time it takes to care for our young (to age 35-40), then we are programmed to slowly die and thus get out of the way for the next generation to do the same.
Species are meant to perpetuate, individuals are not.
That's why i say f-ck genetics, fight the future!
perryscoon said:So is testosterone produced in the ovaries in women?
And why don't women need testosterone for energy? What provides their energy?
High levels of testosterone means sexual, physical & mental energy, stamina & vitality. More importantly for a BBer, is that Free Testosterone is the building block of cellular repair & growth when bound to proteins.sensational said:Exactly how is testosterone correlated with energy. The body's currency for energy is ATP...

Tatyana said:I also hate to break this to you, but humans have a brain that is more designed for monogamy, we have loads of dopamine recpetors (the reward system), over laid the oxytocin-bonding happy happy limbic system.
OneBreath said:LOL, i prefaced with uneducated caveman terms. A concept beyond human comprehension could certainly not be explained by someone as low as me in a few sentences. I was mainly trying to be a little over the top in response to the frustrated "Why the hell does this happen" exclamation.
Its obviously a good thing i have not spread my seed!!![]()

There does seem to be a great deal of confusion about the function of hormones and the body.
During embryogenesis and puberty, the sex hormones are responsible for the differentiation of the embryo to the respective genetic sex, and to develop the secondary sex characteristics.
As adults, they serve more functions besides sex characteristics
Metabolic effects of oestrogen
- inhibits bone reabsorption
-decreases bowel motility
-affects liver function by stimulating protein synthesis, including SHBG and thyroxine binding globulin
-affects coagulation of blood by stimuating the production of the factors II, VII, IX, but decreases platelet aggregation (these factors are also made in the liver)
-effect on plasma lipids, decreasing total cholesterol, increasing HDL, decreasing LDL concentration
-secretagogue for growth hormone
Metabolic effects of testosterone
-spermatogenesis
-maintains the function and structural integrity of the seminal vesicles and prostate gland
-increases the basal metabolic rate through an increase in enzyme and other protein synthesis
- 10-15% increase in RBCs production (especially during puberty)
-increases muscle mass despite an apparent absence of androgen receptors in skeletal muscle, the effect may be due to an inhibition of the normal catabolic effects of the glucocorticosteroids in muscle

Tatyana said:I think as you set your club down and can manage to type out a few sentences, you are beyond the cave man phase.
I have also been working my way through a psychology degree, and things like sexual behaviour have to be viewed from a biological, social psychology, evolutionary, and psychoanalytic perspective (to name a few) if you really want to get a well-rounded view on things.
It is fascinating, sex differences, which ones actually exist, and which ones are socially created.

OneBreath said:Damn, how many degrees do you have? You must be able to soak up info like a sponge to have the knowledge you do and still have time to maintain that body.
I would imagine that not many, even the most educated, could objectively view such a complex subject through each of the perspectives you mention. My "objective" seems to always lean towards whatever perspective i think i know more about(club still in hand)
k for you on that response. Fascinating stuff.
Tatyana said:![]()
I have three degrees, one in biology, one in biomedical sciences, I am one week away from finishing my Master's in Clinical biochemistry and I am doing a psychology degree by distance learning with the Open University.
The two degrees in the middle were part-time while I was working with the NHS, and they funded me to do it.
Tatyana said:Here is a reference range, which may vary a bit from country to country, lab to lab
Test levels for women (in different units)
0.2-2.5 nmol/L
OR
8.7 - 72 ng/dL
OR
86-721 pg/ml
OR
200-2500 pmol/L

Energy = the ability to do work
"In both men and women, testosterone plays a key role in health and well-being as well as in sexual functioning. Examples include enhanced libido, increased energy, increased production of red blood cells and protection against osteoporosis."
"Adult testosterone effects
Adult testosterone effects are more clearly demonstrable in males than in females, but are likely important to both sexes. Some of these effects may decline as testosterone levels decline in the later decades of adult life.
* Libido and clitoral engorgement/penile erection frequency.
* Mental and physical energy"
"Women use testosterones to treat low libido, often a symptom or outcome of hormonal contraceptive use. Women may also use testosterone therapies to treat or prevent loss of bone density, muscle mass and to treat certain kinds of depression and low energy state."

Tatyana said:I think this is where there is a bit of confusion.
Biochemically at the molecular level energy = fuel (as an analogy), which for a cell, are the high energy bonds between the phosphate groups on ATP (adenosine triphosphate).
Creatine also carries high energy phosphates, but it is specialised for muscle cells under anaerobic conditions.
Testosterone is not a fuel, it is more like one of the petrol/gas pedals in the car, which has it speed up.
As far as metabolic pathways go, there are more than one pedal, something like thyroxine is like the gears, what speed you work at.
All hormones have an effect on metabolism in some way, that is what they are, chemical messengers to the cells to co-ordinate their actions.
