the lovely Zanacal found this study and posted it in another topic, so I thought I'dd add it here so the researchers among us can find the info easier
Human sperm characteristics during frequent ejaculation:
See the results section for fascinating tables showing sperm quantities dropping after releasing every 8hrs because there is less seminal fluid with each release so close together

:agree:
Great idea, thank you!!!
wow, fantastic study! thanks girls!!
thats great but for people like me who enjoy the simpler words i have no clue what they are on about lol
hi girls , thanks for this study even if i did'nt understand what to do if we sway for a boy :think:
i m not english speaker native so i try my best to understand what you are writting. thanks again.
Awesome rainbowflower!
That' was pretty hard to understand! Could somebody please put it into simpler words..
Thank you rainbow flower really beneficial!
I'm with you, I found it hard to follow.Quote:

From what I read sounds like what this study is looking at is effect on sperm DNA, shape, and motility when DH practices frequent release (their definition is once ever 8 hours). From what I can gather, the study concluded with frequent release there isn't any effect on DNA or shape of the sperm however, there is a decrease in amount of the enzyme responsible for motility. So even though DH may have good sperm they can't swim as great.
Let me know if anyone else concluded something different!!
they took sperm samples from a variety of healthy men every 8 hours over the course of 2 days:
Sample 1: sperm count and concentration after 3 days abstinence, the control sample
Sample 2: 8 hours after the man released sample 1
Sample 3: 8 hours after the man released sample 2
..
..
Sample 7: another 3 days abstinence following sample 6, to see how sperm count has recovered after such frequent release
The results:
Attachment 7672
This is the most useful explanation... you can see that even after just one release 8hrs after a previous one the total sperm count (and sperm concentration within the semen sample) have drastically dropped, and that these totals continue to drop with every subsequent 8hr release. By the 3rd/4th 8-hourly release these totals level off and are really low. Even after another 3 day abstinence at the end of the frequent releasing sessions the total sperm concentration is still really low, showing that sperm count doesn't recover very quickly I.e. there's lots of semen but lower sperm concentration within the semen 3 days after the end of the FR.
This is the study which helped us discover compressed FR (CFR) for short-term sperm count lowering - if you can release and discard once (maybe twice) then make an attempt within 8hrs of the last attempt you can expect sperm count and concentration to be really low in the sample. Potentially lower than regular frequent release/abstinence.
Hope that makes sense
