Red-Light Irradiation of Horse Spermatozoa Increases Mitochondrial Activity and Motility through Changes in the Motile Sperm Subpopulation Structure.

Biology August 29, 2020 Volume 9, Issue 9 254 doi: 10.3390/biology9090254

Catalán J, Papas M, Gacem S, Mateo-Otero Y, Rodríguez-Gil JE, Miró J, Yeste M.Previous studies in other mammalian species have shown that stimulation of semen with red-light increases sperm motility, mitochondrial activity, and fertilizing capacity. This study sought to determine whether red-light stimulation using a light emitting diode (LED) at 620-630 nm affects sperm motility and structure of motile subpopulations, sperm viability, mitochondrial activity, intracellular ATP levels, rate of O consumption and DNA integrity of horse spermatozoa. For this purpose, nine ejaculates were collected from nine different adult stallions. Upon collection, semen was diluted in Ke...

Marzano G, Moscatelli N, Di Giacomo M, Martino NA, Lacalandra GM, Dell'Aquila ME, Maruccio G, Primiceri E, Chiriacò MS, Zara V, Ferramosca A.Conventional sperm selection techniques used in ARTs rely on centrifugation steps. To date, the different studies reported on the effects of centrifugation on stallion sperm motility provided contrasting results and do not include effects on mitochondrial functionality and different oxidative parameters. The effects of different centrifugation protocols (300 ×g for 5', 300 ×g for 10', 1500 ×g for 5' and 1500 ×g for 10' vs no centrifugation) on motility and oxidative status in cryopreserved stallion sperm, were analyzed. After centrifugation, almost all motility parameters were significantl...

Delgado-Bermúdez A, Noto F, Bonilla-Correal S, Garcia-Bonavila E, Catalán J, Papas M, Bonet S, Miró J, Yeste M.Aquaporins (AQPs), a family of ubiquitous water channels divided into orthodox AQPs, aquaglyceroporins (GLPs), and superAQPs, are present in stallion spermatozoa. The aim of this study was to elucidate the functional relevance of each group of AQPs during stallion sperm cryopreservation through the use of three different inhibitors: acetazolamide (AC), phloretin (PHL) and propanediol (PDO). Sperm quality and function parameters were evaluated in the presence or absence of each inhibitor in fresh and frozen-thawed samples. In the presence of AC, different parameters were altered ( < 0.05), b...
