Return to fertility by method

A large 2020 prospective study (PRESTO, n=17,954) found that return to normal fecundability varies by method. IUDs and implants have the shortest delay (~2 cycles), the pill and ring about 3, and injectables (Depo-Provera) the longest at 5–8 cycles. Lifetime duration of use was not associated with longer delay.

Across all methods, a meta-analysis of 22 studies found an 83% 12-month pregnancy rate after stopping any reversible contraceptive — comparable to the general population.

For Depo specifically, median ovulation return is about 7 months, with ~97% ovulating within 12 months.
