Nocturnal sperm emission in men with psychogenic anejaculation
1Department of Obstetrics and Gynecology, Bikur Cholim Hospital, Jerusalem, Israel.
Objective:
To evaluate sperm characteristics and fertilization potential in sperm obtained from nocturnal emission in men with psychogenic anejaculation.
Design:
Retrospective study.
Setting:
In Vitro Fertilization Unit, Bikur Cholim Hospital, Jerusalem, Israel.
Patient(S):
Six men with psychogenic anejaculation.
Intervention(S):
Nocturnal emission, electroejaculation, sperm cryopreservation, 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 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.
Conclusion(S):
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.
