pH-dependent effects of procaine on equine gamete activation [PDF]

open access: yes, 2019
Procaine directly triggers pH-dependent cytokinesis in equine oocytes and induces hypermotility in stallion spermatozoa, an important event during capacitation. However, procaine-induced hyperactivated motility is abolished when sperm is washed to remove

Influence of complement on sperm motility [PDF]

open access: yesInternational Journal of Andrology, 1990
SummaryIsolated sperm from normo‐, oligo‐ and astheno‐spermic men were incubated for 20 h in medium supplemented with 8% heat‐inactivated or untreated human serum, and in medium with heated or untreated serum deficient in complement factor C3. Before and after incubation, sperm motility was assessed by means of a computer‐assisted semen analyser.

Step by step optimization of a sperm cryopreservation protocol for spotted wolffish (Anarhichas minor Olafsen, 1772) [PDF]

open access: yes, 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 ...

Semen collection and evaluation of captive coatis (Nasua nasua)

open access: yesArquivo 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/

Influence of sperm cryopreservation on sperm motility and proAKAP4 concentration in mice

open access: yesReproductive 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 ...

DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice. [PDF]

open access: yes, 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.

Transcriptome analysis of the testes of male chickens with high and low sperm motility

open access: yesPoultry Science, 2022
: The reproductive performance of chicken breeders has significant economic importance in the poultry industry, and sperm motility is an indicator of reproductive performance. This study performed RNA-seq of the testes of Gushi chicken roosters with high

Optimal analysis conditions for sperm motility parameters with a CASA system in a passerine bird, Passer montanus

open access: yesAvian Research, 2019
Background Sperm motility parameters, which can be measured objectively and repeatedly by a computer-assisted sperm analysis (CASA) system, are important indicators of sperm quality. However, the sperm motility parameters assessed by a CASA system can be
