Deep oral ejaculation therapy is recognized as a specialized treatment performed on male patients' genitals. In addition to traditional stimulation of the glans using oral mucosa, this method now incorporates new procedures such as collecting pre-ejaculate fluid from Cowper's glands, mixing the nurse's and patient's saliva with semen for tongue-based diagnosis, and assessing semen transparency. Clinical results have confirmed that by ingesting semen during treatment, neural compatibility between patient and practitioner improves significantly, greatly enhancing the patient's recovery ability. This is the latest medical technology certified by the Japan Semen Emission Therapy Efficiency Evaluation Organization.
