Infertility due to spinal cord injury (SCI) in young men is a frequent
complication of their injury. When the simpler methods of management of the
erectile and ejaculatory dysfunction that invariably follow the more severe
types of SCI are not effective, then semen production by transrectal
electroejaculation (TREE) combined with in-vitro fertilization (IVF) and
embryo transfer is effective. A retrospective analysis is presented of data
on the treatment and outcome of 35 couples who wished to have a family but
in whom the male partner had suffered SCI. These 35 couples had 71 attempts
at IVF with spermatozoa obtained following TREE. Normal fertilization and
cleavage of the embryos occurred in 48.2% of the oocytes. Fresh embryos
were transferred in 54 cycles and frozen-thawed embryos in 14 cycles. In
all, 18 clinical pregnancies were achieved in 54 fresh and 14 frozen embryo
transfer cycles, with a live birth rate of 16.5% (14/85) per treatment
cycle started, 20.6% (14/68) per transfer cycle and 40.0% (14/35) per
couple who started treatment, in a mean of 1.9 transfer cycles. We conclude
that TREE combined with IVF and embryo transfer is an effective treatment
for the infertility problems associated with SCI.
