Abstract

fetched live from OpenAlex

Cryopreservation of oocytes as a way of preserving fertility for future use can be considered for certain benign diseases and conditions. Benign ovarian cysts, BRCA 1/2 mutation carriers, genetic conditions such as Turner syndrome and Fragile X mutation carriers, and even a low ovarian reserve of unknown origin are examples of such conditions. However, the evidence of the advantage of the procedure is sparse in terms of live births. In general, the recommendation is to freeze oocytes before the age of 38 and preferably >15-20 oocytes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
