Ejaculatory disorder caused by alpha‐1 adrenoceptor antagonists is not retrograde ejaculation but a loss of seminal emission

Abstract

The current study demonstrates that alpha-1a mRNA is predominant among the adrenoceptor subtypes in human seminal vesicles. Decreased capacity of contraction of the seminal vesicles is proposed as the cause of the ejaculatory disorder induced by alpha-1 blockers.
