Neuticles—artificial replacement testicles for dogs—now come in nine (9) sizes, rather than the original three (small, medium, large). Inventor Greg Miller was awarded the 2005 Ig Nobel Medicine Prize for his invention. The new sizes are:
| NU-XXLarge | 140-190 lbs+ | 2.75″ | $329 | $449 |  |
| NU-XLarge | 110-140 lbs | 2.20″ | $319 | $439 | |
| NU-Large | 65-110 lbs | 1.79″ | $309 | $429 | |
| NU-Medium | 40-65 lbs | 1.50″ | $299 | $419 | |
| NU-Smed | 30-50 lbs | 1.27″ | $289 | $409 | |
| NU-Small | 20-30 lbs | 1.04″ | $279 | $399 | |
| NU-XSmall | 10-20lbs | .75″ | $269 | $389 | |
| NU-XXSmall | 3-10 lbs | .63″ | $259 | $379 | |
| NU-Petite | 1- 3 lbs | .44″ | $249 | $369 |
In the chart reproduced here, column 2 shows the weight of the dog, column 3 the length of a neuticle, column 4 the price for a single neuticle and column 5 the price for a pair. Neuticles are also now available in “custom” sizes, for a higher price.
