title: Nocturnal sperm emission in men with psychogenic anejaculation.
abstract: OBJECTIVE
  To evaluate sperm characteristics and fertilization potential in sperm obtained from nocturnal emission in men with psychogenic anejaculation.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  In Vitro Fertilization Unit, Bikur Cholim Hospital, Jerusalem, Israel.
  
  
  METHODS
  Six men with psychogenic anejaculation.
  
  
  METHODS
  Nocturnal emission, electroejaculation, sperm cryopreservation, and assisted reproduction technologies.
  
  
  METHODS
  Semen analysis, intracytoplasmic sperm injection (ICSI), fertilization rates.
  
  
  RESULTS
  In four patients, the concentration and motility of sperm obtained from freeze-thawed nocturnal emission were decreased compared with sperm from electroejaculation. Fertilization rates after ICSI using the nocturnal emission sperm were relatively low (45%). One clinical pregnancy was achieved after intrauterine insemination.
  
  
  CONCLUSIONS
  The quality of sperm from nocturnal emissions is variable, but it can be used in assisted reproduction procedures to avoid aggressive procedures such as electroejaculation or testis biopsy.
