It hardly seems possible that a virile, husky young man, in his early twenties, could be subjected for several hours to the conditions of the modern dance hall, where he is brought into very close physical contact with young women, dressed to expose their secondary sexual features, perfumed to excite in a man his hereditary sexual instincts; held so close to his partner in the round dance that he is conscious of every movement of her limbs, and all of these under the influence of artificial light and music--I say, it is hardly possible for a virile young man to be subjected to all these conditions without experiencing an extreme sexual excitement. That such an experience often repeated not only does not simplify the young man's problem, but seriously complicates it is not a matter of doubt on the part of anyone who has studied these problems. All specialists in this field, without a single exception, concur in the belief that the dance is a device of the devil so far as the young man is concerned. That the young women are, for the most part, quite innocent of the effect of all these conditions upon their young men friends is also believed by those who have studied the problem. If they were conscious of it, a large majority of them would not longer consent to be the party to such unfortunate conditions. The Square Dance, the Virginia Reel and similar dances of the times of our grandparents are not remotely to be compared in this matter with the modern Round Dance. 16. _May lost Virility be regained by use of "Remedies" or medicines of any kind?_ No. Positively and absolutely, _No_. Many such nostrums are advertised in the public prints. Many are sold by charlatans and quacks. No reputable physician would hold out to his patient the hope that any drug could bring back lost manhood. _Lost manhood or lost virility may be regained by right living only._ The prescription for right living is as follows: _Live a continent life_ and follow _a strenuous and sane regime of personal hygiene_, such as outlined in chapter V above. 17. _Is the production of semen modified by nutrition?_ The production of semen is greatly modified by the state of nutrition. Remember in this connection that semen is partly from the testes (Spermatozoa) and partly from the vesicles and prostate. The formation and release of spermatozoa is only slightly modified by the condition of nutrition; while the rate of secretion from the vesicles is greatly modified in quantity. This accounts for the fact that well nourished men who eat heavily are very likely to experience frequent nocturnal emissions, when living continently.
