[The spinal cord injured patient: semen quality and management by Assisted Reproductive Technology]

Abstract

Men with spinal cord injury present a unique infertile population. Only 10 % of them can father children without medical assistance, owing to potential impairments in erection, ejaculation and semen quality. The algorithm typically followed is to retrieve semen by Penile Vibratory Stimulation, in case of failure by Electro Ejaculation. Most of these patients have normal sperm concentrations but abnormally low sperm motility and vitality in the ejaculate. The reasons for poor semen quality in spinal cord injured men are reviewed. If semen cannot be obtained by Electro Ejaculation, or if the ejaculate from Penile Vibratory Stimulation or Electro Ejaculation contains an insufficient quantity or quality of sperm for in vitro fertilization with intracytoplasmic sperm injection, then retrieval of sperm from reproductive tissues is attempted. Despite abnormal semen quality, successful pregnancies with sperm from spinal cord injured male partners have occurred by intravaginal insemination, intrauterine insemination, and in vitro fertilization with intracytoplasmic sperm injection. The prevailing pregnancy and fecundity rates in couples with a spinal cord injured male partner are reviewed.
