I had my first child in my mid 30's, and one of my friends started when both him and his partner were in their 40's. No regrets, but the biological challenges can be very real -- my friends had to use IVF for both their pregnancies. I don't know anyone who had kids a bit later in life who regretted it purely due to their age. Though being now in my mid 40's I think I would struggle with the sleep deprivation and noise of a new baby....
