The healthy limitation of sexual secretion in men sets free a vast store of nervous force for employment in intellectual and active practical pursuits. The amount of nervous energy expended by the male in the temporary act of sexual congress is very great, out of all apparent proportion to its physical results, and is an act not to be too often repeated. In the fully matured and strong adult the nature is adapted to such occasional expenditure, but it is a serious evil to the growing or unconsolidated nature. Even in strong adult life there is a great loss of social power through the squandering of adult energy, which results from any unnatural stimulus given to the appetite of sex in the male. The barbarous custom of polygamy, the degrading habit of promiscuous intercourse, selfish license in marriage, and all artificial excitements which give undue stimulus to the passion of sex, divert an immeasurable amount of mental and moral force from the great work of human advancement. The control possessed so largely by the male over the physical function of sperm-formation is not possessed by the female over the corresponding function of ovulation. In the female, Nature apparently cannot venture to subordinate the simple physical functions of sex to the will, to as great an extent as in the male. A more unyielding rule is needed in these physical activities, because the work to be accomplished for the race by the female is so much more elaborate and long continued. A greater amount of varied action in the complicated organs is necessitated in order to maintain their adult aptitude. The function of ovulation (formation of ova) is not increased or diminished by the will, or by the dwelling of the mind upon sexual objects, at all to the same extent that spermation (formation of sperm) may be affected by the same mental action. Ovulation, and its natural accompaniment, menstruation, is much more of a necessary fixed quantity than spermation and its natural accompaniment, sperm-emission.[3] It is thus seen that the laws guiding the human sexual functions as established by Creative Power are as conducive to health, and as consistent with the freedom and perfection of human growth, in one sex as in the other. Each sex, obeying the Governing Law, is created to help, not destroy the other. The general outline of arrangement is the same in each, viz., power of mental and physical self-balance, strictly guarded potency, and a certain degree of periodicity.
