Age dependence of the number of sensitive cells as implemented in the TMC model: before puberty 2.5 × 108 sensitive cells are present that proliferate during puberty to 5 × 1010 cells. From age 30 this number decreases gradually according to data from ref. (16), and this decrease is accelerated at the onset of menopause. The ages of both puberty (12) and menopause (50) have been optimized in a series of model runs.
