A concise pamphlet surveys non-mechanical birth-control theories grouped as magnetation, including male continence, Karezza, sedular absorption, and similar practices, tracing roots in communal experiments and various European Neo-Malthusian movements. It presents the theory that sexual activity comprises distinct amative and propagative functions and argues semen discharge can be voluntarily withheld, redirecting sexual energy for health and spiritual benefit. The pamphlet compares these approaches with barrier and chemical methods, discusses practical requirements such as emotional bond and discipline, and points readers to foreign literature and organizations that promote reproductive self-control.
