For the semen is a kind of fluid and residual matter. The proof of
this will be given hereafter, but for the present let it taken for
granted. (The like holds good of the menstrual fluid in women, and
of the part where they emit semen. This also, however, is a matter
of which a more accurate account will be given hereafter. For the
present let it be simply stated as a fact, that the catamenia of the
female like the semen of the male are residual matter. Both of them,
moreover, being fluid, it is only natural that the parts which serve
for voidance of the urine should give issue to residues which resemble
it in character.) Of the internal structure of these parts, and of the
differences which exist between the parts concerned with semen and the
parts concerned with conception, a clear account is given in the
book of Researches concerning Animals and in the treatises on Anatomy.
Moreover, I shall have to speak of them again when I come to deal with
Generation. As regards, however, the external shape of these parts, it
is plain enough that they are adapted to their operations, as indeed
of necessity they must be. There are, however, differences in the male
organ corresponding to differences in the body generally. For all
animals are not of an equally sinewy nature. This organ, again, is the
only one that, independently of any morbid change, admits of
augmentation and of diminution of bulk.
