ood to be found sterile.

As to the sexual power of mumps patients, that differs. Some patients
lose their virility entirely; others remain potent, but become
sterile.

The same thing happens to girls attacked by mumps. They may have a
severe inflammation of the ovaries (ovaritis or ooephoritis) or the
inflammation may be so mild as to escape notice. In either case, the
girl when grown to womanhood may find herself sterile.

A man who never had any venereal disease, but who has had mumps,
should have himself examined for sterility before he gets married. As
explained in the chapter "Marriage and Gonorrhea," we can, in the
case of a man, easily find out whether he is fertile or sterile. But,
in the case of a woman, we can not. Time, necessarily, has to answer
that question. In all cases, mumps reduces the chances of fertility,
and no man or woman who once had mumps should get married without
informing the respective partner of the fact. There should be no
concealment before marriage. When the partners to the marriage
contract know of the facts, they can then decide as to whether or not
the marriage is desirable to them.

=Hemophilia, or Bleeders' Disease=

Hemophilia is a peculiar disease, consisting in frequent and often
uncontrollable hemorrhages. The least cut or the pulling of a tooth
may cause a severe or even dangerous hemorrhage. The slightest blow,
squeeze or hurt will cause _ecchymoses_, or discolorations of the
skin. The peculiarity of this hereditary disease is, that it attacks
almost exclusively the males, but is transmitted almost exclusively
through the female members. For instance, Miss A., herself _not_ a
bleeder, comes from a bleeder-family. She marries and has three boys
and three girls; the three boys will be bleeders, the three girls will
not; the three boys marry and have children; their children will
_not_ be bleeders; the three girls marry, and _their male_ children
will be bleeders.

What is the lesson? The lesson is, that boys who are bleeders may
marry, because they will most likely _not_ transmit the disease; but
girls who come from a hemophilic family, irrespective of whether they
themselves are hemophilics or not, must not marry, because most likely
they _will_ transmit the disease.

=Anemia=

Anemia is a poor condition of the blood. The blood may contain an
insufficient number of red blood cells or an insufficient percentage
of the coloring matter of the blood, that is, hemogl
