resorb [rɪˈsɔːb]
vb
(tr) to absorb again
[from Latin resorbēre, from re- + sorbēre to suck in; see absorb]
I believe to absorb would be the correct term, since it happens once not more than once

Besides being wrong on the follicle size, do you have any proof of females developing follicles every year even if not bred?
I have had females not develop follicles at all, large females that bred and never grew follicles, so I'm pretty skeptical to say the least.
