Objective: To evaluate sperm characteristics and fertilization potential in
sperm obtained from nocturnal emission in men with psychogenic anejaculati
on.
Design: Retrospective study.
Setting: In Vitro Fertilization Unit, Bikur Cholim Hospital, Jerusalem, Isr
ael.
Patient(s): Six men with psychogenic anejaculation.
Intervention(s): Nocturnal emission, electroejaculation, sperm cryopreserva
tion, and assisted reproduction technologies.
Main Outcome Measure(s): Semen analysis, intracytoplasmic sperm injection (
ICSI), fertilization rates.
Result(s): In four patients, the concentration and motility of sperm obtain
ed from freeze-thawed nocturnal emission were decreased compared with sperm
from electroejaculation. Fertilization rates after ICSI using the nocturna
l emission sperm were relatively low (45%). One clinical pregnancy was achi
eved after intrauterine insemination.
Conclusion(s): The quality of sperm from nocturnal emissions is variable, b
ut it can be used in assisted reproduction procedures to avoid aggressive p
rocedures such as electroejaculation or testis biopsy. (C) 1999 by American
