Discontinuation of oestradiol implants can lead to prolonged endometrial stimulation, with withdrawal bleeding lasting up to 43 months. This necessitates long-term progestogen therapy to prevent endometrial hyperplasia and carcinoma.

Area of Science:

  • Reproductive Endocrinology
  • Menopause Management
  • Hormone Replacement Therapy

Background:

  • Oestradiol implants are used for oestrogen deficiency symptoms in postmenopausal women.
  • Discontinuation of oestradiol therapy requires understanding of subsequent endometrial effects.

Purpose of the Study:

  • To investigate endometrial stimulation duration after stopping oestradiol implant treatment.
  • To inform management strategies for post-treatment endometrial health.

Main Methods:

  • Follow-up of 10 postmenopausal patients after oestradiol implant cessation.
  • Monitoring withdrawal bleeding patterns with cyclical progestogen therapy.
  • Assessing duration of endometrial stimulation post-implantation.

Main Results:

  • Endometrial stimulation persisted for up to 43 months in four patients.
  • One patient required hysterectomy due to persistent irregular bleeding.
  • Three patients resumed oestrogen therapy due to returning symptoms, continuing to bleed.

Conclusions:

  • Oestradiol implant therapy can result in prolonged endometrial stimulation.
  • Long-term progestogen administration and monitoring are crucial after implant discontinuation.
  • This is essential for preventing endometrial hyperplasia and carcinoma.
