Implication

Ex vivo experimental study demonstrates high baseline oocyte atresia but minimal cold-induced degradation in domestic cats, indicating natural atresia limits in vitro fertilization success.

Key Points

To histologically characterize the baseline atresia status of freshly excised cat follicle-oocyte complexes and determine post-excision taphonomic deterioration during ovarian cold storage for up to 48 hours.
Excision of 50 domestic cat ovarian pairs, where one ovary was fixed immediately and the paired ovary was stored in phosphate-buffered saline at 4 °C for 4, 8, 12, 24, or 48 hours.
Ovaries were classified by stage (follicular vs. luteal), and 2,280 preantral and antral follicle-oocyte complexes were microscopically assessed for structural degeneration.
Across 2,280 evaluated complexes, 64.3% showed slight to severe morphological evidence of atretic degeneration.
Histological assessment revealed no distinct morphological differences between oocytes obtained from follicular versus luteal donors.
Cold saline storage maintained ovarian morphology and suppressed taphonomic deterioration for up to 48 hours post-excision.
