Moreover, there is a growing number of studies showing that males can also adjust the proportion of viable sperm in their ejaculate to the risk of sperm competition [ 13 ] and female mating status [ 14 ].

The dashed red line is the nutritional rail a line in nutrient space that represents a fixed intake of nutrients that passes through the regulated intake point at a P: The growth of sperm banks and fertility clinics, the use of sperm agencies and the availability of anonymous donor sperm have served to make sperm donation a more respectable, and therefore a more socially acceptable, procedure.
