title: Successful treatment of infertility due to anejaculation with in vitro fertilization and embryo transfer: a report of two cases.
abstract: We investigated the efficacy of assisted ejaculation in combination with in vitro fertilization and embryo transfer (IVF-ET) in two couples with infertility due to anejaculation. Case 1 was in an anejaculatory condition associated with a spinal cord-injury. We performed intrauterine insemination (IUI) three times using motile sperm obtained by intrathecal injection of neostigmine, but no pregnancy followed. The couple then entered IVF-ET. The semen volume obtained by assisted ejaculation was 4.5 ml. The sperm count was 33 x 10(6)/ml with 33% motility. At 35 weeks of gestation she delivered three healthy babies by cesarean section. Case 2 was in an unexplained retrograde ejaculatory condition. We performed IUI eight times before changing to IVF-ET. We then used sperm obtained from urine or sperm recovered from the bladder after administration of human tubal fluid, but no pregnancy followed. At the fifth IVF-ET attempt, using sperm obtained from urine, we succeeded. We prepared the sperm by the Percoll gradient method. The sperm count was 36 x 10(6)/ml with 64% motility. At 39 weeks of gestation she delivered a healthy baby. Deficient seminal quality contributes to the decreased fertility potential in patients with anejaculation. With the use of IVF-ET methods, pregnancies can be achieved in these couples.
