Further, with those animals at any rate that have external testes, the semen
is collected together before emission, and emission is due to the penis being
heated by its movement; it is not ready for emission at immediate contact as
in fishes.
All the vivipira have their testes in front, internally or externally, except the
hedgehog; he alone has them near the loin. This is for the same reason as with
birds, because their union must be quick, for the hedgehog does not, like the
other quadrupeds, mount upon the back of the female, but they conjugate
standing upright because of their spines.
So much for the reasons why those animals have testes which have them,
and why they are sometimes external and sometimes internal.

All those animals which have no testes are deficient in this part, as has been
said, not because it is better to be so but simply because of necessity, and
secondly because it is necessary that their copulation should be speedy. Such
is the nature of fish and serpents. Fish copulate throwing themselves
alongside of the females and separating again quickly. For as men and all
such creatures must hold their breath before emitting the semen, so fish at
such times must cease taking in the sea-water, and then they perish easily.
Therefore they must not mature the semen during copulation, as viviparous
land-animals do, but they have it all matured together before the time, so as
not to be maturing it while in contact but to emit it ready matured. So they
have no testes, and the ducts are straight and simple. There is a small part
similar to this connected with the testes in the system of quadrupeds, for part
of the reflected duct is sanguineous and part is not; the fluid is already semen
when it is received by and passes through this latter part, so that once it has
arrived there it is soon emitted in these quadrupeds also. Now in fishes the
whole passage resembles the last section of the reflected part of the duct in
man and similar animals.
