Sperm represents less than 5% of semen so you can't see a difference.
In a one ejaculation there could be anywhere in between 40-600 million sperm. Averaging half a teaspoon. Assuming you are asking about human semen, production ends at death, so the amount of semen production for any one man could be quite large. An average ejaculation is said to produce about 2 ml of semen. Semen is a combination of sperm and fluids produced in the prostate and urinary tract to move the sperm into the vagina. Sperm production can decrease with age due to lessening of testosterone, and the amount of fluids can also deteriorate with age. The prostate starts having problems. I really have no idea how someone came up with the "average" volume of ejaculate. The idea of "sampling" a sufficiently large number of men ejaculating for scientific purposes boggles my mind.

It will decrease too. * * * * * If it is the confidence interval it will NOT decrease, but will increase.

The decrease from 192,000 to 20,000 is 89.583%
No, a man who has had a vasectomy will not have semen in his ejaculate. A vasectomy is a permanent form of male contraception that prevents sperm from being present in the semen.
Semen analysis would be a part of the initial surgical package when the vasectomy was done.
After a vasectomy procedure, the appearance of sperm remains the same. However, the sperm will no longer contain semen, as the vasectomy blocks the tubes that carry semen. This means that the sperm will still be produced by the testicles but will not be able to leave the body.
NO. Exactly the same unless you look at it under a 300x microscope.
Sperm make up a tiny volume of semen, but the testes still do produce some seminal fluids. After a vasectomy, you'll probably have less volume, but it probably won't be noticeable. The prostate gland, and cowpers gland are still fully active and connected post vasectomy, and they make the bulk of semen. It's the removal of the prostate that effects volume the most. After it's removal, many men experience "dry" orgasm.
Yes, men who have had vasectomies still have DNA in their semen. The vasectomy procedure blocks the vas deferens, the tubes that carry sperm, preventing sperm from reaching semen. Semen is still produced by the body, but it does not contain sperm.
I believe you are referring to a vasectomy. Men do not normally have to have this procedure done; it is usually a personal decision. The vasectomy prevents sperm from entering the semen. Therefore, it prevents unwanted pregnancies in women.
No it wont. the only thing a vasectomy does is stop sperm from mixing in with the semen. Only a very small proportion of your ejaculate is sperm/ so everything looks the same and feels the same. You still get the same bang only you will be firing blanks.
Of course men still enjoy sex after a vasectomy! In fact nothing changes except their semen doesn't contain any sperm anymore (what's about 3%) and the fear of (unwanted) pregnancy is (definitively) gone ...
Brown semen can indicate the presence of blood, which may result from various factors such as a minor injury, inflammation, or a medical condition affecting the reproductive system. While a vasectomy can lead to changes in semen consistency and appearance, it should not directly cause brown coloration. It's essential to consult a healthcare professional for an accurate diagnosis and appropriate evaluation, especially if the change persists or is accompanied by other symptoms.
Yes, a man can. My husband had a vasectomy 7 years before I met him and we now have a four year old and we're trying for another. It just means the doctor uses a needle into the testicles and they take sperm from further up, it is a whole lot cheaper and easier than a reversal. You just go see your local IVF unit or GP. They either have to reverse it, or go in to his testicles with a needle and remove the sperm that way. Note: when considering the cost of each proceedure, remember that if you choose IVF, you pay to have the sperm harvested and for each attempted fertilization.
Apparently it is possible in the time shortly after the vasectomy for the tubes to grow back together. After my procedure I was told to bring a couple of semen samples over the next couple of months for analysis.
