Does the vasectomy procedure affect a man's ability to ejaculate?

No. You will still produce a normal ejaculate after your vasectomy. It will be without sperm, but no change will be noticed by you.

No, a man's ability to ejaculate should not be adversely affected by a vasectomy. 98% of the fluid in the ejaculate arises from the seminal vesicles, a reservoir behind the prostate gland. The remaining 2% of the fluid is the actual sperm from the testes. The sperm is blocked from the rest of the ejaculate by the vasectomy, but a man should not notice a change in the ejaculate since the over loss of fluid is so small. The actual process of ejaculation is controlled by certain nerves that are not affected at all by the procedure.

No, not in the least. Sperm are less than 1% of ejaculate volume.

No, there is no scientific connection that a vasectomy would interfere with ejaculation.

The short answer is no.

A vasectomy prevents only the sperm from reaching the ejaculate. The ejaculate, or semen as it is more commonly known, is made up of multiple components, of which the sperm is only 2 to 5 percent. Therefore, it is usually difficult to notice any difference in the volume of the ejaculate or semen. The remaining 95 to 98 percent of the semen is made up of various components to help maintain the sperm, including water, the sugar fructose, vitamin C, citric acid, proteins, enzymes, phosphate and bicarbonate buffers, and zinc. The total volume of semen varies widely among men, but is generally higher in young men. Each teaspoon of ejaculate is estimated to have about five calories and up to 500 million sperm.
