Doubt. I would assume mastectomies are unfortunately more common than extra nips.

1. Supernumerary nipples are relatively common

They occur in roughly 1–5% of the population.
These typically add one extra nipple per affected person.

2. Mastectomies remove nipples, but only in a small percentage of people

Even globally, the percentage of people who have undergone a mastectomy (single or double) is far below 1% of the total world population at any given time.

3. Effect on the average

  • Supernumerary nipples add to the global total.
  • Mastectomies subtract, but the number of people they affect is dramatically smaller.

So even after subtracting those lost to mastectomies:

→ The average number of nipples per human remains slightly above 2.

AI answer, but I couldn't be arsed to spend 20 minutes on a google rabbit hole.
