In chronic spinal cord injury, semen obtained by assisted ejaculation
is usually abnormal. We have assessed electroejaculation early after i
njury in seven patients. There were no adverse effects. Initial sample
s contained few or no spermatozoa but as patients emerged from spinal
shock, semen improved and five had specimens cryopreserved. Thereafter
sperm motility and viability decreased towards the pattern of chronic
spinal cord injury by day 16. Cryopreservation was not possible in on
e patient with many medical complications and another who started elec
troejaculation 15 days after injury. Semen storage within the first 2
weeks after spinal cord injury is recommended for future fertility tre
atment.
