In brief: 3%-10% on average
Monthly fecundity rates decline strongly with age.
Beyond that statement, there is no database or registry of natural conception that would allow quoting statistics, but a rough approximation is that a 35 year-old will conceive on average 1 in 10 ovulations (10% of the time), and a 40 year old 1 out of 30 (3%).
