Experimental reduction in dietary omega-3 polyunsaturated fatty acids depresses sperm competitiveness.

摘要: The health benefits of diets containing rich sources long-chain omega-3 polyunsaturated fatty acids (n-3 LC-PUFA) are well documented and include reductions in the risk several diseases typical Western societies. dietary intake n-3 LC-PUFA has also been linked to fertility, there is abundant evidence that a range ejaculate traits fertility humans, livestock other animals depend on an adequate from sources. However, relatively few studies have explored how influence reproductive fitness, particularly context sexual selection. Here, we show experimental reduction level diet guppies (Poecilia reticulata) depresses male's share paternity when sperm compete for fertilization, confirming currently observed trend reduced western important implications individual fitness.
