Description
Qiqi Yin and co-authors review yak reproduction research, published in 2026, on how the testes develop and make sperm in this high plateau animal. Yaks live with thin air, cold, and altitude stress, and their males show distinct traits, including smaller testes than cattle yet sperm that swims comparably well. Those traits make the yak a useful model for adaptation and sperm energy use.
The review follows molecular events from embryo to old age, covering stem cell renewal, the cell division that halves chromosomes, and sperm shaping. It also uses sterile cattle and yak hybrids, whose sperm making stalls, as a natural clue to the essential steps. Seasonal and breed differences that cloud comparisons are flagged throughout.
