Do bulls that carry the Myostatin gene tend to have smaller testicles?

Not sure about that. But if they are homozygous , then yes, definitely.

Makes sense. Brings to mind a whole new set of bulls

Double blind
Two ignorant
Twice fooled
Twofer
Dumb and dumber

From my own personal experience the affects of the myostatin deletion are not at all consistent. I have a double muscled SH cow. Fairly sure she has 2 copies. She is very muscled, but has calved unassisted, has enough milk and is a good mother. Calves are about 38kg (which is small for here) they don't show muscle at the start, but then do after a couple of weeks.
As with most herds there are a few carriers. One or two carriers seem a bit harder to calf, but most don't. Myostatin free cows that then have myostatin carrier calves are also inconsistent as some calves are larger while many are normal at birth and develop some muscle later. The muscle development is also inconsistent as some carrier calves can have defined muscle while some are the softest easiest fleshing.
Bull testicle size is not consistent either as I had a carrier bull with very large testicles. Some are obviously smaller but I haven't seen a carrier bull with testicles that are too small.  Homogeneous SH bulls can't be registered here so not sure about their testicle size.
All these example would be for the same myostatin deletion.

Please provide info instead of just bumping thread.
