Hi, Ketamine is basically a dissociative anesthetic commonly used in medical settings and rarely used recreationally. While there is limited research specifically investigating the effects of ketamine on sexual function, some studies suggest that high doses or chronic use of ketamine may potentially lead to temporary erectile dysfunction. However, more research is needed to fully understand the relationship between ketamine use and erectile dysfunction. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Muhammad Umer Farooq, General & Family Physician
