Description
Marie Altmanová and co-authors assess in 2026 why a captive jaguar pair in a European zoo breeding program cannot reproduce. Knowledge of jaguar breeding limits in captivity is scarce, yet zoos rely on it for conservation of this threatened cat. Both animals had full checks of their reproductive organs, hormones, and blood, plus semen testing in the male and chromosome screening in both.
Chromosome tests were normal for a cat, with no missing or extra material. The female showed no problem likely to impair fertility. The male's semen, by contrast, showed a marked drop in quality, pointing to him as the likely source. Detailed results are given for each test in the combined assessment.
