NEW YORK (Reuters Health) - The more a man ejaculates each week, the lower his sperm levels fall, new research shows. However, this ejaculatory frequency only partly explains why a man's sperm count varies widely each time it's checked.
The findings, which appear in the medical journal Fertility and Sterility, are based on a study of 27 healthy men who provided monthly semen samples and responded to questionnaires regarding ejaculatory frequency, duration of abstinence, and episodes of fever. The subjects were followed for 16 months.
No seasonal variations in sperm levels, movement, or shape were seen, lead author Dr. Elisabeth Carlsen and colleagues, from Rigshospitalet in Copenhagen, note. However, ejaculation frequency was higher in spring months than in the winter months.
As noted, sperm levels fell as weekly ejaculatory frequency increased. Compared with one ejaculation, sperm level fell 29 percent with two ejaculations and by 41 percent with three ejaculations. In contrast, ejaculatory frequency seemed to have no effect on sperm movement or shape.
The sperm characteristics noted in one sample often differed greatly from those observed in a subsequent sample from the same subject. This wide variation dropped markedly when three semen samples were used instead of two. Ejaculation frequency, duration of abstinence, and the presence of a fever episode were small contributors to this variation.
"The majority of the (this) variation remained unexplained," the authors note.
The findings also suggest that "at least three semen samples should be recommended to estimate an individual's semen profile," they add.

Mine wear fur coats and boots in the winter, sunglasses in the summer, and always fasten their seatbelts before take off.
Yes, I noticed that. If I recall correctly, wasn't there a medical abstract/lookup service run out of Harvard a number of years ago? A medical Lexus/Nexus (sp) as it were. I wouldn't be surprised to find a study like this having been done also by Ortho/Nov or some such company.
Common sense
The "law of diminishing returns" strikes again.
HAH! This headline should read:
Men who don't ejaculate regularly turn into gibbering drooling idiots, study finds. Or disingenuous filmmakers.
As noted, sperm levels fell as weekly ejaculatory frequency increased. Compared with one ejaculation, sperm level fell 29 percent with two ejaculations and by 41 percent with three ejaculations. In contrast, ejaculatory frequency seemed to have no effect on sperm movement or shape.
If movement and shape are unchanged, and level only falls 29% with two ejaculations, aren't you still ahead of the game? Wouldn't it have to fall 50% for it to be a net wash? Sure, you have fewer chances to win each time you play, but you get to play more times, so you're still ahead, so to speak.
Good point...were you math major or do you just spend a lot of time at the track?
bookmarking for educational reference hehe!
I love people who live to learn!
Yes, no, and plus just a believer in general in "more is more" rather than "less is more".
OK, they've got data for twice and three times a week. Do they have data for people who aren't priests or 90 years old? :-)
On the upside, another recent study postulated that frequent ejaculation wards off prostate problems. You don't want that stuff sitting around and rotting in there. C'mon, shake a leg.
Big duh on this one.
Cells take time to divide and multiply.
PING
Like I would care.
Come again?

Just who did they use in this study? LOL!!! I do it quite often and have noticed no evidence of my levels "dropping".
