The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures.
This was a “typical use” failure rate, including user failure to use the method correctly. [12] In comparison, the combined oral contraceptive pill has an actual use failure rate of 2–8%, [13] while intrauterine devices (IUDs) have an actual use failure rate of 0.1–0.8%. [14] Condoms have an actual use failure rate of 10–18%. [9]
The failure rate of a copper IUD is approximately 0.8% and can prevent pregnancy for up to 10 years. The hormonal IUD (also known as levonorgestrel intrauterine system or LNg IUD) releases a small amount of the hormone called progestin that can prevent pregnancy for 3–8 years with a failure rate of 0.1-0.4%.

When the failure rate is decreasing the coefficient of variation is ⩾ 1, and when the failure rate is increasing the coefficient of variation is ⩽ 1. [ clarification needed ] [ 15 ] Note that this result only holds when the failure rate is defined for all t ⩾ 0 [ 16 ] and that the converse result (coefficient of variation determining ...
