How to Store Sperm in 4 Steps – Just in Case


Save the swimmies! (Photo: futurowoman)

I never thought I’d visit a sperm bank.

Perhaps it was flipping a motorcycle at 90 mph on Infineon Raceway.
Perhaps it was tearing my Achilles tendon in jiu-jitsu practice, then getting thrown on my head.
Maybe having my scuba mask fill with blood at 120 feet underwater in Belize?

That could have done it.

Or perhaps is was just crossing the 30-year age threshold and having friends who didn’t make it. 9/11, suicide, accidents — bad things happen to good people.

I came to realize in 2007: it’s really not that hard to die. And that’s when I started thinking about storing my genetic material.

Yes, my little swimmies.

In this post I’ll talk about the process, how I did it, and why it’s cheap insurance in an unpredictable world. I’ll also throw in some curious details (sexy time!) just for entertainment…

The Reasons to Store Sperm

Doing the research, the pros far outweighed the cons:

1) Men are becoming progressively infertile. Go munch on some soy for a mouthful of phytoestrogens, or just stick with preservatives. It’s hard to avoid testicle-unfriendly food and toxins. Talk to endocrinologists who do clinical meta-analysis and get your sperm count measured. It is probably less than your dad’s. Real-world Children of Men (for men) in full effect.

2) There are many medical conditions and procedures — cancer treatment, for example — that can render men infertile.

3) People who “know” they don’t want kids change their minds. A lot. Just look at the number of vasectomy reversal procedures. And no, these procedures do not work well. Failure rates are high.

4) Above all: Why not do it? If you can afford it, it just seems like a no-brainer for bloodline and peace of mind. The potential downside of doing it (cost) is recoverable; the potential downside of not doing it is irreversible.

I’m not a king looking to spread my seed across an empire, but part of me does want to leave a legacy in the form of a child. Call me old-fashioned. I want momma Ferriss to be grandmamma Ferriss at some point, even if I get hit by a cement truck or nailed by blue ice from an airplane.

Think it’s easy to get someone pregnant? Sometimes. Most of the time, after looking at the numbers, it seems surprisingly hit-or-miss.

Does this mean I wouldn’t adopt? Not at all. Several aunts and uncles have adopted, and it’s a beautiful thing. I just also want to have children who share my DNA. I see no reason not to ensure both can happen.

Is this ego-driven? On some level, of course. But so is owning a home or having a decent car, wearing clothing besides what will keep you warm and eating food besides what will keep you alive. Humans are ego-driven with anything past the base necessities for survival.

Sperm Storage – The Steps in Brief

1) Find a sperm storage facility. Google “sperm storage”, “sperm bank”, or “sperm donor” along with your state or city.

2) Make an initial appointment and get tested for infectious diseases.

Most reputable locations will require testing for common STDs prior to storage. I was tested for:

HIV 1 & 2
RPR (for Syphilis, Al Capone’s farewell song)
HCV (for Hepatitis C)
HBsAG and HBcAB (for Hepatitis B)

It’s a romantic first date. And, yes, I cleared like a Mormon taking a drug test.

Cost of initial consult: $100-150
Cost of STD lab panel: $150-200

3) Warm up your wrists and get busy. Six sessions per kid.

Think it’s “one shot, one kill”, macho man? Think again. You’re no Peter North, and even if you were, 50%+ of your sperm count is annihilated from the freezing process.

You should make six sperm deposits for each child you’d like to have. It can take inseminations over eight months for a woman to get pregnant, although in vitro fertilization (IVF) ups the chances somewhat at much higher cost, generally $9,000-12,000 per attempt.

Oh, and forget about abstaining for long periods of time, oddly enough.

For best results in storage/fertilization/impregnation, abstain from ejaculation for at least 48 hours but no more than four days before each session. More than four days and dead sperm cells begin to accumulate and cause trouble, as you need a certain ratio of live sperm to dead sperm per 1 cc (cubic centimeter) of volume. I scheduled one deposit every fourth morning a la: Monday 10am, Friday 10am, Tuesday 10am.

Cost per sample frozen: $150-200 (x 6 = $900 – $1,200 per potential kid)

4) Store all the suspended swimmies somewhere safe.

This will usually be handled by the facility that did the initial freezing. This is also where the credit card comes out.

Cost per year: $300 – 600 (often for all samples)

The E-mail You Need to Read (and Perhaps Replicate)

After my first storage session, I sent the following e-mail to my brother and a number of my closest friends. All names have been changed, but it covers some very possible challenges and necessary sleight-of-hand:

Subject: Critical and Serious E-mail from Tim Ferriss – Please Save

Hello Bill, Bob, Dave, Lisa, and Sarah,

So, after reading “The Last Lecture” and realizing that I have a fairly high-risk lifestyle with motorcycle accidents, jiu-jitsu and all else, I’ve decided to store sperm for potential future use, should something terrible happen to me.

Here’s the situation:

-Beginning today and over several months, I will make approx. 6 deposits at  I am not donating, just storing for worst-case scenarios.
-For a bunch of legal reasons, I had to designate a “partner,” who is the only person with access to the stored samples if something bad happens [Single males are generally unable to store for later use or “just in case”].  I chose Lisa, since she is A) female, and B) easier to reach than Sarah [who’s overseas] via phone.

I’m emailing the five of you because, if something happens to me, I kindly ask all of you to consider female candidates for receiving the samples.  I’d be thrilled if this were Lisa or Sarah, but I certainly wouldn’t expect this.  I’d just want you all to decide together if someone is someone I would approve of or not as the shepherd and missus for my sole progeny.  Bill [my brother] has veto and executive power in the case consensus isn’t reached.  6 deposits gets you 2 impregnation attempts monthly for three months, which is good for one woman only, so please choose wisely if it comes to it.  I would ideally want the resulting child to know my family and spend regular time with them, assuming my family feels the same way.

Again for a host of nonsense FDA and legal reasons, Lisa as “partner” is the only one who can get the samples.  [Storage facility] could help her do procedures on herself with the samples, but if it were for someone else, she’d need to get the samples and you’d all need to figure the rest out.  Sperm only survives for a few hours without freezing, so it would be quite the adventure.

I don’t expect anything to happen to me, of course, but I view this as the ultimate life-insurance policy.  Momma Ferriss wants grandkids, so it’s a relatively cheap way to ensure that happens, no matter what :)

Please ask any questions you might have, and please save this e-mail somewhere safe.  Good idea to print it as well.

Mahalo and see you all soon!


I would be hoping for quite the opposite, whether I play that role or a surrogate mother’s husband does. This entire process is damage control for a worst-case scenario: something catastrophic happening to me.

Sexy Time Details

So, cover the baby’s ears. I’m going to tell you something stunning and disgusting. Something you probably don’t want to hear. Ready? Most guys like pornography. And Santa Clause doesn’t exist. I’m sorry.

Here’s how the storage facility website sells the “donation” process:

“He [the donor/storer] is then shown to a private room where he can collect his specimen in a provided sterile cup.”

About as sexy as lethal injection, right?

Well, upon arrival, there were surprises in store. I was led to a cornucopia of porn DVDs around a secret corner. Right in front of a bunch of female lab technicians looking awkward. There was something for everyone in this motley selection. Norwegian juggler fetish? It would’ve been there. No expense was spared in covering all bases.

I grabbed a few titles (I’ll spare you the names) and headed to a small white room with a sliding door. I followed the lead of a quiet male Asian assistant in a white lab coat. He looked at his feet and departed with “please wash your hands when you finish.” I didn’t expect a call the next day.

The den of clinical sin was about the size of a hotel bathroom, with a paper-sheet-covered cot on the floor (yeah, baby!), a metal chair, a 13″ TV/DVD combo on a small stool, and a stack of magazines suspiciously adhered to one another.

So, I sat down, still quite content and ready to do my duty. A minute of “I can’t believe people want me to do this” and on goes the DVD. Then… my brain got sodomized.

See, I live in San Francisco, and — well — there are a lot of “alternative” sexual orientations. It also happens, sad times for Tim Ferriss, that Mr. Clean-Your-Hands was not good at matching DVDs to their cases.

I had already come to the realization that this room, with paper sheets in all their glory, had been used by hundreds of other donors. That alone required me to enter a state of focus reserved for Olympians and Iron Chef competitors. Then, I turn on the DVD and see two hairy boys doing something resembling wrestling. But not wrestling.

Second DVD, same story. Third time was the charm, but I was already supressing so many images and realities that it was like bending a spoon with my mind to get done what every guy has mastered by age 12.

Ah, Mr. Wash-Your-Hands. We will meet again, and I shall give you a judo chop.

Mentally prepare, gentlemen. It won’t be as easy as you think. These are tough, dangerous times. Good times to save your swimmies as cheap insurance.

And don’t forget to wash your hands.

  1. I kept thinking, “Man, is this going to show up in the new edition of the 4 Hour Work Week? Forget sex with the wife, be more efficient with your time and tell her to use the frozen stuff!”

    But, no pitch on that front and for that I am thankful. Tim, this was useful and hilarious. Thank you.


  2. Dude… where is your blog heading? Saving your sperm?! ;) On a serious note, I might be practically infertile myself, lol. I’ll spare you the details, as well, but my swimmies might not be swimming much. I’m gonna go ahead and get checked up. I’ll report back. Or not. :P


  3. Ahem…now I have stopped chuckling at the pickle you must have been in, I do hope that men reading this in Australia will consider donating their sperm.

    We in Australia have some issue with our men not wanting to give back, and so we outsource our sperm donations to somewhere like Norway (yep great working holiday for those guys).

    Same as above but FREE and the country needs you!


  4. Very funny article Tim. Personally though, I don’t think it should be used if you die. Fair enough if you have some non-lethal accident and loose the use of your wedding tackle then it’s handy to have the spare stuff on ice.

    If you die and one of your friends does go ahead and make your baby, you are leaving that kid without a father from the very start. Secondly, you are not going to be there to have any input in the kids upbringing, nor are you going to be there to protect your own child. Do you really want to do that to your own kid?

    If I were doing this I’d be writing into my will that if I remove myself from the gene pool then the frozen samples should die with me.


  5. You had Tweeted recently about the topic for a new men’s magazine (not porn) column…? THIS type of adventure might be just the folly to capture our ADD-addled attention. “Awkward Moments in a 21st Century Life…” or some such.

    In 15 years or so, you can write about your vasectomy. I’m sure that experience will be one to remember, too…

    Liked by 1 person

  6. I went and did the deed… (they called it the green room at the clinic I went to), got the results back and discovered I had no sperm. So they did a bunch of tests on me, then operated. Turns out I just had a broken pipe! Apart from having both my testicles cut open and going through incredible pain (stitches and loose skin don’t go together well) – I came out with 12 straws now in cryogenic storage! Wifey and I now doing IVF – we have our 4th transfer tomorrow… fingers crossed.

    @Alison – I live in Australia too – I believe it’s more to do with laws/politics/fear of having to pay maintenance, etc, rather than men not wanting to give back.


  7. Hey Tim,

    You did it again! Applying the 80/20 rule to the world of sperm (donation)- nice work! I did have a bit of trouble NOT making the mental pictures throughout a few parts of this post- but I’m OK now. Kim’s still laughing:)

    P.S. Any musts while we’re in Buenos Aires this week?



  8. Tim,

    While this is all very informative, I wish that people could set aside their egos long enough to realize that there are huge numbers of children out there in need of adoption.

    You can leave your legacy with a child you raise just as well as you can with one who shares your biology. Thousands do it each year. Going through all the discomfort, cost, and everything else associated with IVF just because you’re certain that your seed is better really does a disservice to children the world over in need of homes.

    I have several friends who tried IVF for a while and gave up and adopted who say that they couldn’t be happier and that they wish they had saved the IVF money for college funds, etc.

    Saving your sperm is about ego, not practicality. Give an unwanted child a chance at a happy life and you’ll be just as fulfilled as a father.

    Just my $0.02.


    • My boyfriend, who has a child from a previous marriage and is significantly older than myself, is reluctant to get a vasectomy because while he doesn’t want another child, he doesn’t want me to want a child and not be able to have one. I don’t believe it matters. I’d rather adopt a child and make that child know that they are wanted and loved by me, rather than have a child just to pass on my genes.
      And then there’s also embryo adoption, which I’ve been looking into. It’s a fascinating concept and we would pretty much get the best of both worlds, which we would not be eligible for(at least not in Canada), because he does have a child already.


      • Joanne, I don’t understand the logic behind some of your sentences.

        “…boyfriend is reluctant to have a vasectomy, because he doesn’t want another child.”

        I don’t understand. Wouldn’t not wanting another child not not be reason to have a child? (note the double negative)


      • Shaun, i think you may have missed something. She said, “… is reluctant to get a vasectomy because, WHILE he doesn’t want to have another child, he doesn’t want me to want a child…” I added the comma but the “while” makes all the difference, just lettin’ you know ;)


  9. What your post inspires me: Get a life !!
    I know, it’s funny to say that to Tim Ferriss but man… what’s wrong with you ? Forget MommaFerriss, find yourself a nice girl who wants kids too and just do it the old way. Or don’t have kids. What’s the use of “having” kids if you don’t raise them ?
    just my 2 cents


  10. I’ve been thinking about storing my eggs: I’m at the peak of my fertility and not nearly ready for having kids. I don’t want to be 35 and desperate to conceive.
    Maybe a surrogate can help me have kids later, if I take up precautions now.

    It’s seems like a silly, chuckling subject but when looked at closely, it’s a very important one.


  11. Bravo Tim!

    You have taken two very important steps in what I call The Power of Mortality™. You’ve: a) realized and accepted that you are mortal and that no one owes you a certain amount of time on this planet; and b) you’ve taken some concrete action to address that reality. And to have come to this realization at the age of 30 is fantastic, because that’s when you have a much wider range of options available when it comes to choosing the life you really want. But, of course, I would expect nothing less from the master of conscious lifestyle design! Keep up the great work!


  12. Boy can I relate to this post. :-)

    Before getting a vasectomy I got my little guys frozen in facilities in two different cities (extra backups are always a good thing!).

    So far I don’t want any kids while I’m alive (I need my time/money/attention for other things), but I wouldn’t mind leaving part of my inheritance to kids that are born after I’m gone. Also the samples could be useful for future medical treatments.

    Your e-mail helps solve a problem that I was trying to address in a complicated will. Thanks!


  13. Genious article!
    I think this should be taken more serious than most people do, and maybe it`s a good thing to act on it and actually “insure” your kids future.

    I think eating as much food as possible without chemicals and pesticides will make us keep our fertility a littlebit longer. *At least I hope!*

    Norwegian Juggler fetish? That was insulting! haha

    Reply to Allison Reynolds: Are you(Australian people) really outsourcing your sperm donations to here(Norway)?



  14. Tim – love your blog but this article is TMI…

    It’s your body and life and you can do what you want and I’m not going to tell you what to do. However, you are going to create a child and have no part in raising it whatsoever. Things happen and sometimes parents have to raise a child by themselves but purposely planning for that to happen just so your DNA can be passed down – I think that’s irresponsible.


  15. Hi All,

    A few very important points:

    Does this mean I wouldn’t adopt? Not at all. Several aunts and uncles have adopted, and it’s a beautiful thing. I just also want to have children who share my DNA. I see no reason not to ensure both can happen.

    Is this ego-driven? On some level, of course. But so is owning a home or having a decent car, wearing clothing besides what will keep you warm and eating food besides what will keep you alive. Humans are ego-driven with anything past the base necessities for survival.

    Please note I am also not asking that a child be raised without a father.

    I would be hoping for quite the opposite, whether I play that role or a surrogate mother’s husband does. This entire process is damage control for a worst-case scenario: something catastrophic happening to me.

    Hope that helps!



  16. Your sexy details was HILARIOUS (still laughing)

    I wonder if you plan to pick some of your posts and put it in a book anytime in the future? Well, if not, now it’s an idea. Think about how many people who read The 4HWW; definitely a lot more than the number of subscribers to your blog (I assume) – a book would reach many more.

    Thx for the inspiration, again.

    Enjoy Mexico. Go dive at Santa Rosa Wall – BEAUTIFUL!
