Penile vibratory stimulation and electroejaculation in the treatment of ejaculatory dysfunction / 中华男科学杂志

ABSTRACT

The fertility potential of infertile men can be enhanced to a great extent by the application of assisted reproduction techniques such as intrauterine insemination or in-vitro fertilization with or without intracytoplasmic sperm injection, but how to obtain semen from men with ejaculatory dysfunction remains a problem. The development and refinement of penile vibratory stimulation (PVS) and electroejaculation (EEJ) have significantly brightened the prospects for the treatment of ejaculatory dysfunction. Because vibratory stimulation is non-invasive and easy to perform, and needs no anaesthesia, it is preferred by most of the patients to EEJ, and recommended to be the first choice of treatment for ejaculatory dysfunction. Approximately 80% of all ejaculatory dysfunction men with an intact ejaculatory reflex arc (above T10 ) can obtain antegrade ejaculation by PVS. Any condition which affects the ejaculatory mechanism of the central and/or peripheral nervous system including surgical nerve injury may be treated successfully by EEJ. The purpose of this review is to present the current understanding of PVS and EEJ procedures and their clinical use in men with ejaculatory dysfunction.
