A les\u00e3o do m\u00fasculo isquiocavernoso (LMIC) foi identificada como um fator associado \u00e0 disfun\u00e7\u00e3o er\u00e9til (DE)<sup>3<\/sup>, particularmente no contexto de trauma p\u00e9lvico.

A extens\u00e3o da LMIC pode influenciar a natureza e o progn\u00f3stico da DE associada; por exemplo, a LMIC unilateral tem sido associada \u00e0 DE transit\u00f3ria, enquanto a LMIC bilateral pode resultar em uma DE mais permanente<sup>3<\/sup>.<\/p>\r\n<p>Compreender o contexto cl\u00ednico do m\u00fasculo isquiocavernoso \u00e9, portanto, importante na avalia\u00e7\u00e3o e no manejo de pacientes com DE, especialmente aqueles com hist\u00f3rico de les\u00e3o p\u00e9lvica.
