Congenital bilateral absence of the vas deferens (CBAVD) is a genetic abnormality that prevents the development of the vas deferens. The vas deferens is the tube that carries sperm from the testes. CBAVD keeps sperm from exiting the body. CBAVD can also lead to azoospermia, an extremely low sperm count.

Possible Cause

  •     Cystic fibrosis


  •     Lack of sperm during ejaculation


  • Semen analysis
  • Genetic testing- to check for cystic fibrosis

Medical Therapy

  • Intracytoplasmic sperm insemination (ICSI)
  • Intrauterine insemination (IUI)
  • In vitro fertilization (IVF)
