Inability to Ejaculate

Inability to ejaculate (anejaculation) is usually caused by inability to reach orgasm. It usually occurs as part of erectile dysfunction. Causes, diagnosis, and treatment are the same as for erectile dysfunction (see Sexual Dysfunction in Men: Erectile Dysfunction (ED)). Retrograde ejaculation can sometimes result in absence of visible semen.
