Possibly chemicals, but, alternatively, natural selection has been relaxed across the board in the modern societies since agriculture and even more after industrialization. How often do you see males literally fighting over sexual access to a female, which would select for physically healthy males?
Selection pressure for intelligence may have increased, but education level is negatively correlated with reproduction, so maybe not. Multiple generations of relaxed selection would have a cumulative effect on health AND sperm production.

Women nowadays accept males indiscriminately? Reproduction success is the same for everybody across the board? That's news to me and I very much doubt the veracity of such a bold claim. Natural selection is very much alive.
