The milky white color of the male’s ejaculation is the sperm, right? After vasectomy is the ejaculation more like pre-cum?


  • Michael Castleman says:

    Semen is a milky white color not because of the sperm, but because of the nutrients that feed the sperm: sugars, vitamins, and minerals. Sperm account for only 2 percent of ejaculate by volume. After a vasectomy, the man’s ejaculate looks exactly the same: same color, and same amount. You don’t notice the loss of the sperm because they account for such a small proportion of the ejaculate.
