Clinical review of ejaculatory dysfunction

Ejaculatory dysfunction (EjD) is a complex pathological condition compared to erectile dysfunction (ED). A definitive classification of EjD is not established, and treatment is often delayed. Owing to its association with infertility, EjD is a serious concern, particularly in men of reproductive age.

The authors performed a literature search to identify the latest articles and overseas guidelines for review.

Our new classification categorizes men into two groups as follows: (1) men with inability to ejaculate (retrograde ejaculation, anejaculation, intravaginal ejaculatory dysfunction) and (2) men requiring an abnormal time for ejaculation (premature ejaculation, delayed ejaculation). In Japan, the number of men presenting with an inability to ejaculate is greater than those presenting with premature ejaculation. Pharmacotherapy is the first-line treatment for the management of these EjD patients. Behavioral therapy is added to pharmacotherapy depending on the case. Penile vibratory stimulation or electroejaculation is indicated in some men with retrograde ejaculation and anejaculation. In cases who hope for a baby, assisted reproductive technology should be simultaneously considered not to waste time.

It is important to distinguish between EjD and ED and accurately diagnose the type of EjD for optimal treatment of this condition.
