| WHAT IS SEMEN MADE OF?
As mentioned previously, the average, healthy man will have anywhere from 120 million to 600 million sperm in a single ejaculation. Besides sperm, semen contains water; simple sugars (to provide fuel for sperm); alkalies (to protect sperm against the acidity of the male urethra and the vagina); prostaglandins (substances that cause contractions of the uterus and fallopian tubes, and are thought to aid in the sperm's passage to the womb); vitamin C; zinc; cholesterol; and a few other things.
