Different patterns of metabolic cryo-damage in domestic cat (Felis catus) and cheetah (Acinonyx jubatus) spermatozoa

Felid spermatozoa are sensitive to cryopreservation-induced damage, but functional losses can be mitigated by post-thaw swim-up or … Read more »

Oxidative phosphorylation is essential for felid sperm function, but is substantially lower in cheetah (Acinonyx jubatus) compared to domestic cat (Felis catus) ejaculate

Compared with the normospermic domestic cat, sperm metabolic function is compromised in the teratospermic cat and cheetah, … Read more »

Increasing age influences uterine integrity, but not ovarian function or oocyte quality in the cheetah (Acinonyx jubatus)

Although the cheetah (Acinonyx jubatus) routinely lives for more than 12 yr in ex situ collections, females … Read more »

Individual genetic diversity does not predict ejaculate quality in captive or wild-born cheetahs (Acinonyx jubatus)

Terrell, K., Crosier, A.E., Wildt. D.E., O’Brien, S.J. David, V.A., Anthony, N.M., Crumples, N., Marker, L.L, Johnson, … Read more »

Oxidative metabolism is required for sperm motility and viability in felids, but may be impaired in cheetah (Acinonyx jubatus) ejaculates

Teratospermia (ejaculation of ≥ 60% structurally abnormal spermatozoa)is common in certain felid species or populations, especiallyin the … Read more »

Evidence for compromised metabolic function and limited glucose uptake in spermatazoa form the teratospermic domestic cat (Felis catus) and cheetah (Acinonyx jubatus)

Cheetahs and certain other felids consistently ejaculate high proportions (≥ 60%) of malformed spermatozoa, a condition known … Read more »

Improved quality of cryopreserved cheetah (Acinonyx jubatus) spermatozoa after centrifugation through accudenz
