Abstract

fetched live from OpenAlex

An effective oocyte cryopreservation program benefits infertile couples with moral or religious objections about cryopreservation of embryos. When considering all pregnancies and live births obtained from cryopreserved oocytes using the classic slow-freezing method, the survival rates averaged approximately 50%. The percentage of live births per thawed egg ranges from 1 to 10% using the classic slow-freezing protocols. Recently, improved survival and pregnancy rates have been reported using modified slow-freezing procedures, particularly increased sucrose concentration in the suspending solution, and the use of sodium-free freezing solutions. Several attempts have been made with immature human oocytes. Although survival rates seemed to be improved by the slow-freezing method, poor in vitro maturation (IVM) and fertilization are major problems associated with immature egg freezing. Rapid cooling (vitrification) of human oocytes has resulted in relatively higher survival rates. This study suggested that better results can be achieved by vitrifying mature oocytes rather than immature 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.
