PART 21
XXI. A constitution of this kind prevents fertility.
The men have no great desire for intercourse because
of the moistness of their constitution and the softness
and chill of their abdomen, which are the greatest
checks on venery. Moreover, the constant jolting
on their horses unfits them for intercourse. Such
are the causes of barrenness in the men ; in the
women they are the fatness and moistness of their
flesh, which are such that the womb cannot absorb
the seed. For neither is their monthly purging as
it should be, but scanty and late, while the mouth
of the womb is closed by fat and does not admit the
seed. They are personally fat and lazy, and their
[p. 127]
abdomen is cold and soft. These are the causes
which make the Scythian race unfertile. A clear
proof is afforded by their slave-girls. These, because
of their activity and leanness of body, no sooner go
to a man than they are with child.
