Do Your Sperm a Favor: Eat Salmon not Soy!

In a recent investigation Brazilian scientists (Moraes. 2010) found that vitamin E from salmon, but not soy oil, has beneficial effects on sperm motality and resistance to cooling to 17° respectively 5°. The scientists supplemented twenty-four Dalboar 85 boars with three different amounts of antioxidants (150, 300 and 450 vitamin E mg/kg) from one of the sources and conducted a few standard tests at 24h, 48h, and 72h after the supplementation:
Salmon oil increased the vigor in both temperatures evaluated after 24 and 48 hours. The occurence of total morphological abnormalities was higher in the semen of animals fed soybean oil and cooled at 17ºC while in the lowest cooling temperature (5ºC) there was no difference among animals under supplementation. [...] Salmon oil improves the sperm characteristics of the boar semen cooled at 17 and 5ºC from 24 to 48 hours.
"No soy boy!". The good old BB-saying holds true no matter how hard animal rights activists are pushing to get me off my bloody steaks and raw eggs... Ah.. I forgot my sushi!
