No Blessing on marital relations? discusses a before blessing.

Why is there no after blessing for ejaculation?

Here are some reasons why ejaculation is different from sneezing

  1. It occurs in the "nether regions", like the other asher yatzar activities
  2. It involves substance moving from deep within the body to outside the body whereas the substance of a sneeze is not very deep within the body.

  • Yes! If your ureter is blocked during ejaculation, your semen will backfire into your bladder. I can't find info on whether this is unhealthy, but if it happens every time, one won't be able to have children. Mar 12, 2014 at 21:01

Asher Yatzar says "that if one of them were opened or one of them were closed, a person would be unable to maintain himself" i.e. the functions that we say Asher Yatzar on pose health problems would we not be able to perform them. Many people get vasectomies and are fine. So the blessing isn't appropriate.

  • People survive colostomies too.

    @DoubleAA I'm not sure why providing an alternate route for waste proves anything? That faculty is not ended, just rerouted. Mar 12, 2014 at 20:53
  • Vasectomies don't stop semen production TTBOMK; it just gets rerouted.

  • @DoubleAA see here it is reabsorbed, not emitted. As opposed to waste, which has an alternate route to emission. Mar 12, 2014 at 20:58
  • Define emitted. It leaves the regular שבילי הזרע.
