Serious request, honest! - Size of bulls' testicles

[Saffy]

Maybe the tape was cold too and particularly noticable when pulled tight. :D

They definitely carry lower in the hotter weather but I don't know that that would have anything to do with circumference.
Is bull virility necessarily a measure of fertility? Is it likely that a bull with low sperm count and low motility could possibly demonstrate above average virility.

I would imagine there's a myriad of factors involved but on the other hand, I wouldn't chose to use a bull with small testicles. In my bible of cattle, the author says that he wouldn't use a bull with a testicular circumference below 36 cm at 12 months of age in his particular herd. He is talking about animals of medium size (bigger than dexters obviously but not the massive animals of today). He says other things like the testicles should be the same size, hang straight without a twist, but the main thing for him is that the bull should be very masculine, physically a fighting machine, and that is the best indication of his labido and how his calves will perform. But that does include being fairly well endowed.

A critical statement in what he says, of particular relevance to your interest Louisa, is that the male hormones will stop his growth when he reaches his ideal weight and that he would not chose a bull that has grown too large. He doesn't say this, but the assumption would be I suppose that the largeness would indicate a lack of sufficient male hormones? But that must be relative to his particular breeds (medium-sized Angus and Hereford and their crosses).

Yes but I mean as in activity rather than measurement. Should I have said is libido relevant to fertility? Margaret.

I looked it up. There is 'good evidence' that it is relevant.
