Seasonality affects post-thaw plasma membrane intactness and sperm velocities in spermatozoa from Thai AI swamp buffaloes (Bubalus bubalis)

Storage of buffalo (Bubalus bubalis) bull semen in the cryopreserved state is discussed in this article. Fertility rate in buffalo following artificial insemination with frozen-thawed semen is reviewed. To better understand the freezability of bubaline spermatozoa, the available data on biochemical components and the activity of specific enzymes of semen/spermatozoa are given. Moreover, the major factors that may influence the post-thaw viability and fertility of buffalo spermatozoa are examined in detail. In addition, suggestions for improvement in cryogenic procedures for buffalo spermatozoa are also given.

“…Reports on the effects of season on semen production are contradictory. While in many studies, season significantly influenced semen production (Fiaz et al, 2010;Koonjanek et al, 2007;Mathevon et al, 1998;Nichi et al, 2006;Stålhammar et al,1989), other investigations (Brito et al, 2002), failed to detect an effect of the seasons on sperm production. Although Stålhammar et al (1989) observed the highest concentration and total number of spermatozoa during the summer season, in a study done in Sweden, Mathevon et al (1998), reported the highest values of these parameters during winter and spring, in a study that was conducted in Canada.…”

“…Although Koonjaenak and others (2007) and Nichi and others (2006) studied the effect of hot and humid weather on sperm quality of bulls and related species such as buffaloes, few studies have investigated the effects of climate on sperm quality in Europe. There is one study in Sweden (Valeanu and others 2015), a country with a temperate climate, reporting seasonal differences in bull sperm quality.…”

The aim of the present study was to evaluate the possible effects of climate factors on sperm quality of Holstein dairy bulls housed in northern Spain. Semen samples from 11 Holstein dairy bulls were collected and cryopreserved in winter, spring and summer. Sperm quality parameters such as motility, morphology, plasma membrane integrity, acrosome status, mitochondrial membrane potential, DNA fragmentation index and reactive oxygen species were assessed. Samples collected in spring showed higher mean values of total and progressive motility compared with samples collected in winter. Mean values of average path velocity and straight-line velocity were higher in spring than in summer. The proportion of viable spermatozoa was higher in spring than in winter as was the proportion of viable spermatozoa with non-reacted acrosome. The proportion of live cells that were not producing superoxide or hydrogen peroxide was higher in samples collected in spring than in winter. No differences were found in sperm morphology or the DNA fragmentation index among seasons. In conclusion, results suggest that sperm quality of bulls housed in northern Spain is affected by season. Samples collected in spring appear to have better sperm quality than samples collected in other seasons.
