FALSE with respect to Progestase is

Progesterone IUD (Progestase) The veical shaft is fitted with a capsule containing 38 mg of progesterone dispensed in silicone oil. It delivers progesterone to the uterus at the rate of 65 micrograms/day. Though a few sources claim the effectiveness to be of 2 years, the US Food and Drug Administration (USFDA)-approved effective life is only 1 year. The contraceptive effectiveness of the progestase is similar to that of Cu IUDs; it reduces menstrual loss but has to be replaced every year and possibly increases the risk of ectopic pregnancy (as it decreases tubal motility).
