Rat & Mouse Line Rescue


The first step to rescuing your line is to determine the cause of the reduced or absent breeding performance. We have a variety of tools at our disposal to accomplish this task, including:

  • Superovulation followed by oocyte collection and analysis to determine female fertility
  • Computerized sperm analysis to determine male fertility
  • Observational matings to determine copulation ability
  • Embryo collection and analysis at various stages to determine if implantation and growth are occurring


Once the cause and severity of the fertility problem has been assessed, we have several services specifically designed to overcome the issue, including:

  • Foster nursing
  • Ovarian transplantation
  • Artificial insemination
  • Laser-assisted in vitro fertilization (IVF)
