This invention provides methods, compositions and contraceptive devices that use sulfonated compounds that interact with sperm to inhibit fertilization. The device comprises a plurality of solid electrolyte plates and first to third electrochemical cells. The device as described above may be implemented more variously according to embodiments. A limiter limits, based on the parameter monitored by the parameter detector, generation of the drive signal by the generator to limit an increase of a level of the harmonic current.
