Thanks Animus. there's something in what you said that made me think that although the maturing cycle is 74 days, this may not mean that the regeneration cycle is 74 days. The epididymis is a very thin and entangled tube several (was it 15) meters long. The sperm matures here, so must take it's time to pass through it. Even if we ejaculate, I suspect, and seem to remember that it can't really leave the epididymis until it's ready.

However, that which we eject, needs to be replaced, so a new load, corresponding to that ejected is produced, but is less than the whole 74 days worth.

In the picture there's a sort of bulbous structure, beside the seminal sac. Perhaps that stores about 5 days worth.

The only problem with this theory is that this sort of implies that the regeneration is more or less constant. Continually feeding sperm into the epididymis at a constant rate, filling a sac for immediate use.

hello daveman, emi
yes, I think it happens at a continuous pace- like at an assembly line. The sperm are manufactured in the testes, and the epididymis is part maturation chamber and part storage facility- like a warehouse. So maybe you're right in that it can hold about "x" ejaculations of mature sperm or so... However it is being continually replenished at a slow daily pace.

Whenever we ejaculate I don't think the epididymis is emptied completely- it's more like some trucks came to take a "load" from the warehouse (no pun intended!) but didn't take everything.

What also strikes me as interesting is that sperm are a living organism and a lot more complex than the rest of the fluids that make up semen. They are only about 5%. The rest is secretions, which are non-living, and perhaps don't take as much maturation period? This is the question I curious about is- what the regeneration time is for the rest of the ejaculate...

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.

Great idea! I know that it is possible to do such a pie chart in Excel, or something similar, but I don't know many about autocad.

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?

Thank you. It would be great if more members (not only me) could have access to edit it, but you can post here, and I'll add it to the main post until a solution will be found.
Maybe Daveman know how this should be done. Finally I think the best solution is having a wiki. Daveman said it would be on his agenda.
Yes I'll want to work more on it with you.
I haven't progressed with research these days, I'll see what I'll do, because I have days when I don't feel good.

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.

Dave Edit: OK smaller now!

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 m. for a few hours (my plan was to have arousal but nog O.). Not so smart. Look what happened: I had a rash on the hand which touched the sperm. For me this is another prove that in my case it's about allergies. Of course maybe there are other causes too.

P.S. Animus asked me to post this picture.

Daveman · « **Reply #27 on:** June 15, 2011, 01:57:50 PM »

emi_b, send me a PM to remind me about the showing of images to non-members. I'll also try to resize the photo.

It would be great to se a pie chart according to components too somebody!

Thanks, Emi,
I'll try to work on it some more over the weekend when I have more time. Or looks like Dave may be able to help too. That would be great. Thanks, Dave.
best,

Dave: Awesome job on shrinking the pie chart. Thanks, it looks great.

I came across an interesting fact while researching the composiition of semen.
Apparently the Seminal Vesicles produce these Prostaglandins, which are "involved in suppressing an immune response by the female against the foreign semen". I thought that was interesting- in terms of the auto-immune theory, because this could be something to investigate regarding POIS. I wonder if they are looking at these prostaglandins more. I just thought it was interesting. So there is a component of semen which is meant to suppress the immune system.

On Wikipedia:

Seminal Vesicles create:
amino acids, citrate, enzymes, flavins, fructose (the main energy source of sperm cells, which rely entirely on sugars from the seminal plasma for energy), phosphorylcholine, prostaglandins (involved in suppressing an immune response by the female against the foreign semen), proteins, vitamin C

This is an interesting point. Has anyone has their estrogen levels checked? If estrogen levels are elevated, then maybe that's causing the attack.

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)...

emi_b · « **Reply #33 on:** June 19, 2011, 01:25:11 PM »

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.

I completely understand. Thanks for your excellent work, Emi_b! Thanks for posting that image on the main post, it looks great.

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.

There should be some sort of option in the guest usergroup. At least that's how it works in vbulletin.

Yeah, that's where it was. I went there already but I hadn't looked close enough, it was the second to last option.

Thanks!
