Sperm Levels Drop with Frequent Ejaculation

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.

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.

Hold on let me play the clinton advocate.

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.

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.

A funny (and true) story: A friend of mine was having some problems with his urination (don't ask). So the doctor tells him he'll need a sample. The day of the test the nurse hands him a cup and points to the bathroom. My friend walks in and a few seconds later walks back out and says, out loud and in front of a group of nurses, "Where are the magazines and videos?" The nurse gets pissed off and yells, "IT'S A URINE SAMPLE!"

The Jeff Foxworthy version is much funnier. "Out of the Gene Pool" from the album "Games Rednecks Play" released in 1996.

The volunteers were mostly seamen.

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