Abstract

fetched live from OpenAlex

BACKGROUND: Random-start, controlled ovarian stimulation (COS) has advanced the field of fertility preservation, allowing patients to expedite fertility treatment and avoid further delays to their cancer therapy. This novel approach allows patients to initiate ovarian stimulation at any point, regardless of where they are in their menstrual cycle. Luteal-phase start (LPS) protocols describe treatment cycles where COS is initiated during the luteal-phase of the menstrual cycle. LPS protocols have not been studied or optimized to the same degree as conventional, early-follicular COS. Particularly, there is a paucity of evidence evaluating treatment outcomes using different trigger medications in LPS protocols. The present study aims to evaluate the efficacy of using a GnRH agonist (GnRH-a) trigger in patients undergoing oocyte cryopreservation in LPS protocols. METHODS: This descriptive case series describes two patients, recently diagnosed with cancer, who underwent oocyte cryopreservation using an LPS protocol and a GnRH-a trigger at a university-affiliated, academic center. RESULTS: The patients described in our case series both failed to adequately respond to a GnRH-a trigger, based on their serum levels of luteinizing hormone (LH) and progesterone 12 h after their GnRH-a trigger. They both required a single rescue dose of human chorionic gonadotropin (hCG). CONCLUSIONS: These findings highlight the potential risk of a suboptimal response to a GnRH-a trigger in patients undergoing LPS, controlled ovarian stimulation for oocyte cryopreservation. This risk might be attributed to the downregulation of GnRH receptors by elevated serum progesterone levels during the luteal phase. Currently, there is insufficient evidence to recommend for or against the use of a GnRH-a trigger during LPS controlled ovarian stimulation. This case series offers a number of management strategies to mitigate this risk and emphasizes the need for further research in this area.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
