In each diet pair, males consumed significantly more of the high-C diet than the high-P diet electronic supplementary material, figure S2. Second, we show that sperm production was maximized at a P: A controlled study in 65 men with low testosterone levels and vitamin D deficiency supported these findings. Compensation by locusts for changes in dietary nutrients: There is also some evidence that vitamin C supplements may improve semen quality. Exercising not only improves your confidence and physical performance — it may also raise your testosterone levels.
There are about mg of fructose per mL seminal fluid  and it appears to be higher in men who are more fertile.
How to increase your sperm count and keep it up: lots of great sex, cold baths and garlic
Large donors transfer more sperm, but depletion is faster in a promiscuous hermaphrodite. However, our experimental design means that we cannot completely rule out that some of the variation in the nutritional landscape for male fertility is influenced by contributions from the female or other constituents of the ejaculate. Diet consumption was calculated as the difference in dry weight of diet before and after feeding. Furthermore, sperm viability is also traded against attractiveness [ 23 ] and immune function [ 24 ] in several species.
