Research output: Contribution to journalArticleResearchpeer-review


This is a report of a 26-year-old schizophrenic man treated with triazolam, levomepromazine, trifluoperazine and biperiden, who showed complete absence of spermatozoa in seminal analysis with normal plasma hormone levels. Sperm count reached 151 × 106/ml after 6 months of triazolam withdrawal. A reversible effect of triazolam is suggested at the level of the germinal cells which are differentiating, without affecting the stem cells.
