great research ! We can try to find those standards easily for the hormones section :)
Yes, i understand ! The matter is "i got info in some forums... :-[" so, it was like a summery !
I found out the "seminal liquid components" (to complete perhaps) :
The exact composition of seminal fluid is detailed below:
Composition of seminal fluid
Quantity: 2 to 6 ml
PH value: 7 to 8 (slightly alkaline buffer)
Secretions of seminal vesicles: 75% of the volume, secretion and alkaline fructose (1.5 to 6.5 mg / ml), phosphorylcholine, ascorbic acid
Prostatic secretions: 20 to 25% by volume, biogenic amines (spermidine, spermine), citric acid, cholesterol, phospholipids, proteases affected the liquefaction of the ejaculate (fibrinolysin, fibrinogenase)
Other components: phosphate buffer and bicarbonate, prostaglandins, hyaluronidase, cellular waste from the cells of Sertoli cells at early stages of spermatogenesis, lymphocytes.
If we take the immune semen allergy theory... IF we have mild symptoms while getting aroused it means we have an allergy (or some reaction whatever it is called) to one of those components !
I would take this segment and copy/paste it right below the section of the male anatomy...

Semen Production Cycle
1. Sperm are manufactured in the testes in the seminiferous tubules, and after their heads and tails are developed, they move to the epididymis to mature further.
2. They are stored there until they are ready to be expelled from the body. During ejaculation, the sperm are pushed up the vas deferens, a tube which loops around the bladder.
3. The ends of the vas deferentia (plural of vas deferens) are known as ejaculatory ducts, and here, the sperm mixes with semen from the seminal vesicles.
4. The ducts lead to the urethra; the prostate adds its secretions to the fluid at this time.
The Cowper's glands, or bulbourethral glands, also add secretions.
5. The semen with all the sperm and secretions is then ejaculated through the rest of the urethra and out into the woman's body.
I've updated the post. Thank you for this.
I hope I formated well it and it look pleasantly.
Should I add the contributor name? It could be better.
I believe it would be better that anyone to contribute directly to this, so if you have any thing to add to it write here and I will try to add it on the main post.
Maybe when a mini-wiki (as Daveman said) will be implemented on the main website, things will be simplified.
It is hard to work in BCCode, for such a project. (the source code of the post is not very humman readable)

I see that the part about the regeneration time is not included. And that's fine for the moment, because there seems to be a conflict. Up until now I've heard that the regeneration time is near the same 5 days that POIS seems to last. And such is a factor in the theory of POIS itself being related to sperm regeneration. But Animus's article indicates 74 days.
I think it's important that we eventually include the regeneration time in the main post, but let's look it up and clear up this conflicting information.
Thx.
Hey, emi,
What do you think of a pie-chart for the semen composition divided up by gland? Such as mentioned in my previous post. I think it could be interesting. Maybe I'll try to do it. what is good for that? Colorful pie chart, I could make it in autocad, but there is probably a better program for it.
Emi- I'm committed to building up your thread with interesting facts and illustrations. Hope to work on it more with you. How is your research coming along?
I made this pie-chart to illustrate the relative volumes of fluid by gland. It's very interesting for me to visualize this, I was surprised to see how significant a portion of semen apparently is made by the Seminal Vesicles.
Hopefully we can add this to the illustrations on the first post... thanks- Animus.

Wow! It looks great. Good job. Thank you for this. :) Great illustration.
I have tried to put it on the main post and there are some problems:
1. It is very large. Almost as big as the whole post. Maybe we should shrink it.
2. Because it is a post attached file, it isn't visible for non-loged members, and non-members.
Any solutions?
I've put the image on the main post.
I'll hope to come with more things and more work, on this topic, when I feel better, because I don't feel good these days.
There are some interesting things with these findings.
I hope there is no problem.
Thank you.
Hi Emi,
It looks like daveman was able to reduce the size of the pie chart! Which is great. do you think it might fit now into the main post? And let's ask dave about getting the images to be viewed by non-members. Eventually we'll straighten out the image viewing problem. But let's try to get the images in there. Thanks, Animus.
I like the image of the sperm too. Can we include that? make a separate chapter on the sperm component? We can also say that full sperm development takes 74 days. (I'm still looking for information about regeneration of the 95% other fluids)...
There should be some sort of option in the guest usergroup. At least that's how it works in vbulletin.Hi Emi,

Didn't have much luck with seeing how to let unregistered users see the images. But I'm back with a mre consistent access to internet so I'll keep looking into it.

I completely understand. Thank you for your excellent work, Emi_b, it is even more impressive considering what you are going through. Thanks for posting that image on the main post, it looks great.
I'm back.
I've put the sperm image on the main post.
Animus if you want you can write a section for semen regeneration, and I will try to insert it in the right place on the main post.
I saw you found many resources. Good findings.
Thank you.
in relation to the sperm regeneration question. This 5 day sperm regeneration period is the time that it takes for the final conversion of sperm in the epididymis. This is the most important part, because it is the part that is triggered by sperm loss/ejaculation. when we ejaculate and lose sperm, the sperm that have been constantly produced and maturing over the last two and half months are sent to the epididymis. There is a testosterone spike that corresponds with the maturation of the sperm in the epididymis, the testies produce increased amounts of testosterone which in turn cause the maturation process to occur. A member of the NSF purchased a article on testosterone levels after ejaculation probably about a year ago. it shows that after ejaculation the loss of the small amount of matured sperm from the epididymis causes testosterone levels to rise from the normal baseline for 7 days, once the small amount of mature sperm are replaced on day 7 testosterone levels fall back to baseline rapidly by day 8. so on day 7 the total testosterone spike from baseline has returned to normal. From days 0-5 there is a slow gradual increase in testostrone, from day 6-7 there is a huge spike in testosterone, it is believed that this spike pushes testosterone levels past the threshold of the hypothalamic-pituitary axis and turns the entire process off. In the article it said that everybody has this 7 day cycle. It also states that if you have an ejaculation before the end of this 7 day cycle the cycle will just start over again and will last for another 7 days. If you dont wait 7 days between every ejaculation you will be in the beginning of this cycle continuously. This is the reason in the past that I have talked about one of the neuro-endocrine chemicals involved with the process of sperm regeneration being the culprit for an immunological reaction. this would make much more sense that this antigen that is causing an immune reaction is continues during this week long process than just a single exposure to something like your own semen lasting 7 days.I would take this segment and copy/paste it right below the section of the male anatomy...

Lauracostis,check your messages and then I will send it to you in an email
your above post is fascinating. I would like to read the article you refer to. do you have a link to it? Please PM me or otherwise post. One of the reasons I'm excited is because we're starting to see that there is a relationship between the period of semen regeneration and the period of POIS. However tentative it might be at the moment. I would like to cite this data in our main page post and formalize it. But I would need a specific footnote or reference. Thank you.
best regards,
Animus
good job on the graphs animus.
