... When it comes to how successful sperm will be! :)
THURSDAY, Nov. 15 (HealthDay News) -- Men with wide variation in the length of their sperm, particularly in the tail, have lower concentrations of sperm that are good swimmers, a new study indicates.
The finding could provide doctors with a new marker for fertility problems in men, the researchers suggest.
In the study, the investigators analyzed sperm from 103 men and found that those with sperm with longer overall length, longer tail length and higher tail-to-head length ratios had higher concentrations of sperm that are good swimmers. They also found that the greater the variation in sperm length, particularly tail length, the lower a man's concentration of sperm that could swim well.
