Thank you very much for opening up the discussion on my post, frankly speaking , I do not have a confirmed answer to the question, though I am looking for one, and that is why I have added the phrase " I believe ". I will only explain to you why I believe that regular sexual activity ( well within the physiological limit of one's body) should increase the testo level in men.
I think the incremental testo being produced on a daily basis is the sum of the testo being used up by the body and the testo being flushed out by the liver, so that the total and free testo level in the blood are maintained to a more or less constant level. To this one may add some amount towards the half life period of the testo in the body. Since both the ejaculate and the spermatogenesis uses up testo, the first result of an ejaculation should be an increased demand on the free testo in preparation for the next ejaculate. Depending on the time constant of the brain's feedback system, the pituitary should now increase the level of LH to compensate for the reduction in the free testo in the blood. So, if a continuous demand for testo is maintained over a period, ( say few months), the leydig cells metabolism should increase, which in turn make them produce more testo in active young adults. As more testo is being produced, correspondingly more DHT and Estrogen will also be produced. So, the end result will be to stabilize the testo level to some higher level than what it was.
Similarly, through long term abstinence, the testo levels should drift to a lower level. This is well in agreement with the concept that regular use of a biological organ is important for its health.
I would like to hear more comments from the members.
I'm not sure about the idea that sexual activity increases the testosterone level in your body. It seems like testosterone is at a level, whatever it is, caused by the hypothalmus, and does not respond to external stimuli. It's not adrenaline, after all. Women's estrogen level goes up and down, but not because of having sex. It does so for reasons of the body's own, and she just has to cope, if it is too low or too high. I think testosterone is the same way.
Generally it is believed that male pattern baldness is a family trait and if so, you can not any way escape it. There are some medicines to block DHT conversion process, but they may be risky to use for a simple physical look. I personally feel that sexual activity would increase the serum testo level and therefore the chances of increased production of DHT, but abstaining may not necessarily solve the problem if it is in your genes.
From another site:
"Most men are genetically predisposed to male pattern baldness. It is the effect of hormones on the hair follicle that produces male pattern baldness. Testosterone, a hormone that is present in high levels in males after puberty, is converted to dihydrotestosterone (DHT) by an enzyme called 5-alpha reductase. DHT has an adverse affect on the hair follicles. Acting on a hormone receptor on the hair follicle it slows down hair production and produces weak, shorter hair, sometimes it stops hair growth from the follicle completely. This process gradually depletes your stock of hair and is normal hair loss."
In other words, sky950, testosterone is present in your system because you are human being, and present in a noticeable amount because you are a male. It could be true to say that you masturbate because of testosterone. Also, the guys who lose their hair do so because of testosterone, but masturbation doesn't cause hair loss, and it doesn't cause testosterone to increase either.
(If masturbation caused baldness, there would be no hair on of 94% of the men in the world.)
Male pattern baldness is caused by testosterone.
