1. The human cell contains 75 MB of genetic information
2. A sperm 37.5 MB.
3. In a milliliter, we have 100 million sperms.
4. On average, one ejaculation releases 2.25 ml in 5 seconds.
Using basic math we can compute the bandwidth of the human male penis as:
(37.5MB x 100M x 2.25)/5 = (37,500,000 bytes/sperm x 100,000,000 sperm/ml x 2.25 ml) / 5 seconds = 1,687,500,000,000,000 bytes/sec = 1,687.5 TeraBytes/sec
That’s in the order of Petabytes. After laughing about it, you may wonder if the calculation is correct. Well, keep reading for our ordinary investigations in this profound question that will surely cheer up any casual conversation.
THE CD-SPERM COINCIDENCE
Information in our genome is encoded as a sequence of nucleotides in the DNA. Knowing the total number of relevant nucleotides (forming a base pair) is pretty straightforward: in a reference haploid human genome there are some 3,1 billion of them. Since there are four types of nucleotides in our DNA (the famous “TGCA” letters, or GATTACA for your mnemonics), each base-pair represent 2 bits of information, meaning that would you to record all of them it would take some 6,2 billion bits, which translates to around 740 megabytes. Roughly the data that fits a single CD.
Now, as a side information, we are in fact diploid, having two of each autosome and two sex chromosomes. Meaning we have double that calculated value of data in our cells, which amounts to 1,44 Gigabytes. Each tiny one of your 100 trillion cells has double the data of a CD encoded in a tiny strand of DNA.
But back to the human penis data bandwidth.
The human sperm is indeed haploid – half the data that will be joined with the other half in the human egg –, which means that it does have around 740 Megabytes of raw genetic data as we calculated at first.
Which also means it’s a funny coincidence a single sperm has around the same amount of data as a single CD. Sperm data capacity is a reference far more interesting than Beethoven’s 9th Symphony, by the way.
Well, the calculation quoted at the beginning of this post is wrong, a sperm has around 20 times 37.5 MB. Now, correcting that error, and knowing that the values for average sperm count and ejaculation volume are correct, you would have:
(6.2 x 10^9 bits/sperm) x (100 x 10^6 sperm/ml) x (2.25 ml) / 5 seconds
1395 x 10^15 bits / 5 seconds
2.8 x 10^17 bits/sec
human penis data bandwidth.
You could have simply multiplied the initial value by 20 to get to roughly the same value, but anyway, an average human penis would be transmitting 31 Petabytes, or 31 quadrillion bytes of raw data per second during its climax performance.
That’s more than all data processed by Google every day; two times all the data produced by the Large Hadron Collider per year; thirty times all the users’ photos in Facebook – already roughly 10 billion photos. It far exceeds the bandwidth of any current data transmission technology.
Amazing, huh? Say hello to our little friend.
