About this study

  • Etonogestrel implants (Implanon) are widely used for postpartum contraception. However, the timing of insertion may influence menstrual patterns, including irregular bleeding, amenorrhea, and prolonged bleeding episodes. Despite the increasing use of immediate postpartum contraception, there is limited research on how the timing of Implanon insertion affects menstrual cycle regulation.
  • Furthermore, lactation and hormonal changes postpartum may modify the bleeding patterns in women using Implanon, with breastfeeding women experiencing a higher likelihood of amenorrhea due to prolactin-induced suppression of ovulation.
  • This study aims to fill these gaps by systematically comparing menstrual outcomes based on timing of Implanon insertion postpartum
