How to say "ed" in Japanese

• 勃起障害ぼっきしょうがい
  nounCovers 'ED' in the erectile-dysfunction sense: a medical term, literally 'erection disorder', for the inability to get or keep an erection, seen in medical consultations and health writing. A less common equivalent.
• 勃起不全ぼっきふぜん
  nounAlso renders 'ED' as erectile dysfunction: literally 'erection failure', a near-synonym of 勃起障害 for the same condition, seen in medical and pharmaceutical contexts. Like that word, a less common choice.
• 緊急救命室きんきゅうきゅうめいしつ
  nounCovers 'ED' in the hospital sense, the emergency room or emergency department. Literally 'emergency life-saving room'; a less common rendering, familiar to many from the Japanese title of the American TV drama 'ER'.

For 'ED' as erectile dysfunction choose 勃起障害 or 勃起不全, both medical terms for the same condition, while the hospital emergency-department sense corresponds to 緊急救命室; all three are less common equivalents.
