title: Testicular perfusion apparatus.
abstract: OBJECTIVE
  A reproductive biology laboratory requires to provide reliable instruments for regular use of research workers. To understand an organ and perform scientific study and reach on a conclusion good instruments and techniques are essential. Such a suitable one is not available in case of testicular study. The present study is aimed to clear this lacuna.
  
  
  METHODS
  A new testicular perfusion apparatus for rabbit and rat is designed and fabricated with glass. The glass blowing instrument available is used. The perfusion fluid preferred is Krebs Ringer bicarbonate buffer (pH 7.4). Quartz wool provided in stem tube filters emboli present in it. Perfusate temperature is maintained to that of testis. A 26-gauge needle is introduced into the spermatic artery to allow entry of perfusate into testis. Method for the collection of perfusate leaving testis is available. This permits to measure the level of an injected substance before its entry through perfusion fluid into the testis, which shall be compared in the fluid after completion of perfusion.
  
  
  RESULTS
  Initially few animal testes were used and found the instrument to be functioning well.
  
  
  CONCLUSIONS
  A new simple perfusion apparatus for testes of rabbit and rat is designed. The apparatus made out of glass could be prepared with the help of glass blowing facility and used regularly in any laboratory.
