I asked my father about your question about the camel's testicles. He said yes, this is true, but not all camels have one testicle larger than the other, Greetings soliman

There is another piece of information that my father told me, which is that if the camel’s right testicle is alive (larger than the left), then the camel is suitable for pollination of the female camel, but if the opposite happens, if the left testicle is larger than the right here, the camel is not suitable for pollination.

So Robert Irwin was right about a camel’s mismatched testicles. But he didn’t say why this is. So I asked KhairAllah. In none of the scientific literature, not in “Seasonal Anatomical Changes in the Testis of the One Humped Camel: A Review”, Pasha, R.H. et al. (European Journal of Anatomy, 2013) nor in “Some Studies in Testis Function of the Camel”, El Doush, I.E. (MVS Thesis, University of Khartoum, 1988), have I found such a cogent answer as his.
