when there is some direct reference to health as influenced by the
sexual functions.

[Sidenote: Social hygiene.]

Social hygiene in its complete sense means the great general movement
for the improvement of the conditions of life in all lines in which
there is social ill health or need of social reform; but it is often
limited to the sexual aspect of the unfortunate and unfavorable
conditions of life, and it has been proposed to adopt the term "social
hygiene" as a substitute that avoids the word "sex" in sex-hygiene. For
this reason it has been incorporated into the names of several
societies that are interested in sex-hygiene (_e.g._, the American
Social Hygiene Association). Probably the relation of sex-hygiene to
the so-called "social evil" has suggested the use of social hygiene in
its most limited sense. It will be unfortunate if this usage becomes so
prominent that we think of the health problems of society as chiefly
sexual, for the larger outlook of Ellis's "Task of Social Hygiene" is
desirable. Likewise, the phrase "social evil" in the sense of sexual
evil misleadingly suggests that the only evil of society is the sexual
one, but this evasive designation is being supplanted by the more
definite and franker word "prostitution."

It should be noted that "social hygiene" as a substitute for
"sex-hygiene" is narrower in that it does not include the personal
problems of health as affected by sexual processes. This is a serious
omission, for certainly all sex-hygiene taught before the later
adolescent years should be personal and not social.
