I suspect due to the same reasons that T levels have also fallen over the decades:
Sperm count more than halved in Western men
In the largest study of its kind, researchers find that sperm count in Western countries has more than halved in recent decades. Outside of these countries, however, the decline is not significant.
The question of whether or not sperm count is declining has been hotly debated for many years within the scientific community. However, no firm conclusion has been reached.
Of course, a reduced sperm count has important implications for reproduction, but this is not the only reason for alarm; low sperm count has been shown to increase the risk of all-cause mortality and morbidity."
