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 × 106/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 rom the bladde 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 36×106/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. © 1998 Tohoku University Medical Press.
