Sperm is the longest-lived animal on the planet. The average lifespan of adult sperm is a whopping 72 years. A study by the University of Minnesota concluded that sperm that were collected from three hundred men who had donated their sperm to be used in research was, on average, two more years old than sperm from the same three hundred donors who were not recruited for the study.
I’m not sure of the exact number, but the study found that sperm was “six months” to “eight years” old, which is like ten times that of the average sperm and a huge improvement over the two years sperm has been used in the past. It also found that most sperm were “fertile,” meaning they were able to fertilize an egg.
This is great news, because once we know sperm is this important to human reproduction, we can start to design a sperm bank. Not sure how long it will take, but the results are looking very positive.
Another great news is that the sperm bank is a huge step forward in human reproductive science. For years we have used sperm to “save the day” when we were having trouble getting pregnant. We used it to transfer healthy sperm to a woman when we were “too old” to have a baby naturally. We used it to fertilize eggs, and so on.
Although we’ve all been using sperm to help us get pregnant, we’ve never really used it to create a baby. In fact, our sperm bank is one of the few places where we actually create new human beings.
The sperm bank is actually a very well-organized, efficient sperm bank. We create, store, and use sperm to make a huge number of spermatozoa, which are then cryogenically frozen (aka. “frozen”), so that they will survive in a liquid nitrogen bath for years to come. Sperm stored this way are so good for our offspring that they are the best sperm for the job.
We don’t just store sperm. We also store it in our sperm bank, and then cryogenically freeze it, and then store that frozen sperm in liquid nitrogen.
We also store sperm in our sperm bank. If you are a sperm donor, you should absolutely donate your sperm. Not only is it a great way to save your sperm bank a lot of money, but it’s also one of the easiest things you can do to improve the quality of your sperm. Since we are storing sperm in liquid nitrogen, we have the added advantage of being able to use it to freeze sperm from a younger donor.
This is a great point. Sperm is only one of those things that can be improved. Sperm banks have a lot more work to do in the areas of genetics, reproductive health, and in vitro fertilization. There is also the fact that, unlike our sperm, we’re not going to be able to use our sperm in any way directly to impregnate a woman. Just like I’m not going to be able to impregnate my wife with my sperm.
In many ways, sperm is like a drug. For a while it was taken for granted that the sperm of a younger man could fertilize a younger woman, but that has been shown to be untrue. The sperm of a man of a certain age are not as good at fertilizing younger women. There has been a huge amount of research done on the subject and, as a result, sperm banks now have a much better idea of what they can and cannot do.
