This study examined whether
flossing the teeth is a more effective collection method in recovering
spermatozoa than conventional swabbing techniques. It was hypothesized that
inclusion of flossing as a collection method would extend the recovery of
spermatozoa to longer postcoital intervals (PCIs).
Eighteen individuals
provided 174 oral cavity samples. Successful recovery of spermatozoa was assessed
with respect to the collection method and reported activity in the oral cavity
during the PCI. Samples were subjected to a differential extraction procedure
prior to microscopic evaluation of the extracted pellet.
The results indicate
that swabbing is more effective than flossing when the PCI falls within 1.5-12
h. However, spermatozoa were recovered from seven floss samples where the
corresponding swabs gave negative results.
When combining the results from the
two collection methods, the percentage of subjects from whom spermatozoa are
recovered increases for each PCI beyond the 0-h interval.
