*5.5.1 Non-contraceptive uses*

Implants do not disturb lactation and reduce the risk of ectopic pregnancy and symptomatic PID, probably as a result of the effects of progestin on the cervical mucus; moreover, they may protect against iron-deficiency anemia. Furthermore, implants do not increase the risk of STIs [78, 81]. Implants have been shown to be beneficial in women with dysmenorrhea as they decrease abdominal cramps by up to 80% [112]. Unlike DMPA, etonogestrel implants have not been found to induce bone loss [78, 110].
