The aim of present study was to evaluate intra-abdominal laparoscopic technique in free range male rhesus macaque in terms of rapidity and specificity of the technique . Two hundred twenty free range rhesus macaques were captured by cage trapping method. Anesthesia was achieved using xylazine @2mg/kg and ketamine @ 10mg/kg body weight intramuscularly. One midline and two lateral pre-umblical surgical ports were created. A telescope was inserted through midline port while cutting and grasping forceps were inserted through the lateral ports. About 3-4cm long fragment of vas deferens was removed by cutting and cauterization, using atraumatic thermo-cautery forceps and a scissors connected to an electrocautery unit. The induction time, duration of anaesthesia and recovery time was 2.10 ± 0.20 min, 72 ±0.28 min and 38±0.12 min respectively. Surgical time for laparoscopic vasectomy was found to be 2±0.32 min. The method was found to be simple, easy and faster method of vasectomy in the male rhesus macaques.
