This study details a rare case of recurrent empty follicle syndrome (EFS) in a patient undergoing intracytoplasmic injection. Despite two cycles of treatment, no oocytes were retrieved, highlighting challenges in assisted reproduction.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Research
  • Assisted Reproductive Technology

Background:

  • A patient with male factor infertility (azoospermia) underwent intracytoplasmic injection (ICSI).
  • Initial treatment involved oral contraceptives, gonadotropin-releasing hormone agonist, and gonadotropin therapy for ovarian stimulation.
  • The first oocyte retrieval after human chorionic gonadotropin (HCG) administration yielded no oocytes despite follicle aspiration and flushing.

Observation:

  • A second treatment cycle two years later utilized identical stimulation protocols but a different HCG batch.
  • Despite repeated aspiration and flushing of follicles, no oocytes were retrieved in the second cycle.
  • Serum beta-HCG and progesterone levels were within expected ranges on the day of retrieval.

Findings:

Related Experiment Videos

  • This case represents the first reported instance of recurrent empty follicle syndrome (EFS).
  • No oocytes were retrieved in two separate treatment cycles despite standardized protocols.
  • Management was achieved without repeating HCG injection on the day of unsuccessful oocyte retrieval.

Implications:

  • Recurrent EFS poses significant challenges in assisted reproduction, necessitating careful patient management.
  • Understanding the underlying mechanisms of EFS is crucial for improving IVF success rates.
  • This case highlights the potential for successful management of recurrent EFS without additional HCG administration.
