Step by step optimization of a sperm cryopreservation protocol for spotted wolffish (Anarhichas minor Olafsen, 1772) [PDF]
, 2020 Spotted wolffish Anarhichas minor reproduction in captivity is dependent on in vitro fertilization. However, low sperm volume with relatively low cell concentration and the lack of gametes synchronization (simultaneous availability of mature eggs and ...

DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice. [PDF]
, 2020 Although thousands of genetically modified mouse strains have been cryopreserved by sperm freezing, the likelihood of cryorecovery success cannot be accurately predicted using conventional sperm parameters.

Influence of sperm cryopreservation on sperm motility and proAKAP4 concentration in mice
Reproductive Medicine and Biology, 2022 Background The protein proAKAP4 is crucial for sperm motility and has been suggested as an indicator of male fertility. We determined the relationship between proAKAP4 concentration and sperm motility parameters in mice, and investigated the effects of ...

Factors affecting sperm recovery rates and survival after centrifugation of equine semen [PDF]
, 2012 Conventional centrifugation protocols result in important sperm losses during removal of the supernatant. In this study, the effect of centrifugation force (400 or 900 × g), duration (5 or 10 min), and column height (20 or 40 mL; Experiment 1); sperm ...

Semen collection and evaluation of captive coatis (Nasua nasua)
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2012 Semen samples (n=105) were collected through eletroejaculation from six adult male coatis (Nasua nasua) between January 2007 and December 2008 at Universidade Federal de Mato Grosso Zoo, Cuiabá, Brazil. Mean values were: volume (mL); concentration (sperm/

High concentration of dopamine treatment may induce acceleration of human sperm motility
Reproductive Medicine and Biology, 2022 Purpose In humans, catecholamines (including dopamine) have been identified in semen and fallopian tubes, while dopamine D2 receptors (D2DR) are found in the sperm midpiece region.
