Possible reasons... 1) Sperm better resists the flood of estrogen chemicals and produces more babies. 2) Random chemicals in the environment are mutating the Y gene faster (so change is not coming from a benefit just a lot of random change) 3) Sperm lasts longer to evade birth control as long as possible. Male sperm production is down by about 1/20th of what it used to be the last I read so there is a lot of pressure here. 4) Mutated sperm trying to develop laser beams to cut through condoms and diaphragms.
