News From a Distant Planet:

On the distant planet there is a major industry
devoted to the enhancement of the libido.
For some unknown reason the male libido
has become irascible. Males are aroused
until the moment they are ready to insert.
Overwhelming aversion know as "Coital Nausea"
ensues and the male is unable to continue.

Scientists are currently battling hard, for they
fear a dangerous subsiding of species propagation.
