The result usually arrives quietly. An email, a portal login, a page of numbers with reference ranges beside them and no one there to explain what any of it means. Most men read it alone, several times, and then sit with it for a while before telling anyone.
If that’s where you are: male factor is involved in roughly half of all couples who struggle to conceive. You are in very ordinary company, even though it doesn’t feel that way.
This article is not a list of every treatment that exists. Those already fill the internet, and they’re hard to use, because they describe what medicine can do rather than what applies to you. This is meant to be a map of your situation instead.
Here’s the honest frame before we start. For some men, this is genuinely fixable. For many more, it’s workable. The goal shifts from raising your numbers to getting one good sperm to one good egg, and medicine is very good at that. For a small number, the path to a biological child does close. There are routes to a family from all three of those places.
First, the thing nobody tells you: one result isn’t a diagnosis
Semen quality moves around far more than people expect. A fever six weeks ago, a stressful stretch at work, a course of medication, how long it had been since you last ejaculated, whether the sample got to the lab quickly and warm, all of it shows up in the numbers.
That’s why a diagnosis isn’t made on one test. Guidelines are clear that you should have at least two semen analyses, usually a few weeks to a few months apart, before anyone draws conclusions. A meaningful number of men see noticeably different results the second time.
And then there’s the fact that governs everything else in this article:
Sperm takes roughly 72 to 90 days to make.
Whatever you change today, the drinking, the weight, the hot tub, the medication you didn’t know was a problem, shows up in a sample three months from now. Not next week. Not next month. This is the single most useful thing to know early, because it’s the reason men give up on changes at week five, convinced nothing is happening, when the change hasn’t had time to reach a test yet.
If you want the detail on what’s actually worth changing, we’ve covered it separately in our 90-day guide to improving male fertility.
Where do you actually fit? Four situations
Almost every man reading this falls into one of four groups. Which group you’re in decides which treatments are even on the table, and it’s the reason generic treatment lists feel so useless. You end up reading three paragraphs about surgical sperm retrieval when your issue is motility.
- Your numbers are low, but sperm is there. Low concentration, poor movement, unusual shape, or some combination. This is the largest group by far. Options here run from lifestyle changes and hunting for a treatable cause, through medication and surgery, to assisted reproduction if you need it.
- Sperm is being made, but it can’t get out. This is obstructive azoospermia – a blockage. A previous vasectomy, scarring from an old infection, a complication from childhood surgery, or a vas deferens you were born without. Frustrating, but often the most fixable group, and the one with the best odds if sperm needs to be retrieved surgically.
- Very little or no sperm is being made. Non-obstructive azoospermia. This is the hardest group, and the one where men most often assume the door has closed. It hasn’t necessarily. This is where micro-TESE comes in, and we’ll get to the real numbers below.
- Everything looks fine and nobody can say why. Roughly 30 to 40% of men diagnosed with male factor infertility fall into the unexplained, or idiopathic, category. Genuinely maddening. Treated pragmatically rather than curatively.
Which box you’re in gets decided by a fairly standard set of tests: a repeat semen analysis, a hormone panel (FSH, LH and testosterone at minimum), a physical examination, usually a scrotal ultrasound, and, if you have azoospermia or a very severe count, genetic testing.
If you haven’t had those yet, that’s the conversation to have before any treatment gets discussed. Our guide to who actually treats male infertility covers who orders what.
Find your group above. You can skim the rest.
Things that can be fixed, and what “fixed” honestly means
A varicocele
Enlarged veins around the testicle, which let it run warmer than it should. It’s the most common correctable cause of male infertility, and it’s found in a substantial share of men who come in with poor semen results.
Repair is usually microsurgical, done as a day case under local or general anaesthetic. Most men are back at a desk within a few days and back to full activity in two to three weeks.
On the evidence, be a little careful with what you’re promised. Semen parameters do improve reliably in well-selected men. The effect on actual live births is less certain. The Cochrane review of varicocele treatment concluded it remains unclear whether treatment improves live birth rates, though it may improve the chance of pregnancy, and several more recent meta-analyses have been more favourable.
So the question worth asking your surgeon isn’t “does this work.” It’s: given my numbers and my partner’s age, what do you expect this to buy us, and how long will we wait before we know? Repair takes months to show up in a semen analysis, and time is not a neutral resource when your partner is 38.
Hormones that are out of balance
If your FSH, LH or testosterone are off, medication can genuinely lift or restart sperm production. Clomiphene citrate, letrozole, hCG and FSH injections are the usual tools, depending on exactly what’s out of balance. In many countries several of these are prescribed off-label for this purpose, which is normal and worth understanding rather than worrying about.
These work on the same biological clock as everything else. Months, not weeks.
If you’re taking testosterone right now
This matters more than anything else on this page, so it’s worth saying plainly and without judgement.
Testosterone replacement therapy shuts down the signal your body uses to make sperm. So do anabolic steroids. Men on TRT frequently have very low or zero sperm counts, and a lot of them have no idea that’s the reason, including men who were prescribed it legitimately for low energy or low mood.
Sperm production usually recovers after stopping, but it can take many months, and recovery isn’t guaranteed.
If you’re on testosterone in any form, tell the doctor before a single treatment decision gets made. It may change the entire plan.
A blockage
If sperm is being made but can’t get out, the options are reconstruction or retrieval.
Reconstruction means surgically reopening the pathway – a vasectomy reversal, or repair of an obstruction caused by old infection or previous surgery. When it works, you’re back to conceiving without a clinic involved.
Retrieval means collecting sperm directly and using it in the lab, which we cover further down.
For men after a vasectomy, reversal versus retrieval is a real decision rather than an obvious one. It depends on how long ago the vasectomy was, the cost structure where you live, and, heavily, your partner’s age, because reversal buys a chance at natural conception but costs you months of waiting to find out.
Infections, medications and things you take
Genuine infections get treated with antibiotics. Beyond that, a surprising number of everyday medications quietly suppress sperm production. For example, some drugs for blood pressure, ulcers, mood, hair loss, autoimmune conditions and more.
Write down everything you take, including supplements and anything you buy without a prescription, and hand the list over. This is one of the cheapest possible fixes and it’s missed constantly.
And when it’s nothing you did
This part deserves its own paragraph, because a lot of men arrive at this diagnosis quietly convinced they caused it.
Genetic causes like Klinefelter syndrome or Y-chromosome microdeletions. An undescended testicle in childhood. Mumps after puberty. Cancer treatment. A congenital absence of the vas deferens linked to cystic fibrosis genetics. Or, very often, no identifiable reason at all.
Most of what shows up on a semen analysis was not a choice you made. Guilt is nearly universal here and almost always misplaced.
Lifestyle: what it moves, and what it doesn’t
Lifestyle change is the cheapest and safest lever you have, and in men whose habits are working against them it demonstrably shifts semen parameters.
It is also not a cure for a blockage, and it will not fix genetic azoospermia. Both halves of that sentence are true, and clinics tend to emphasise whichever half suits the conversation.
The headline items are unglamorous and you already suspect most of them: carrying excess weight, smoking of any kind including vapes, heavy alcohol use, recreational drugs, chronic poor sleep, and sustained heat on the testicles from hot tubs, saunas or a laptop that lives in your lap.
Supplements deserve a straighter answer than they usually get. The Cochrane review of antioxidants in subfertile men found a possible increase in live birth and clinical pregnancy rates, but the certainty of that evidence is low, and the apparent benefit disappeared when the poorest-quality studies were removed from the analysis. More is also not better. Over-supplementing can push things in the wrong direction. It’s worth a conversation with your doctor rather than a shopping trip.
Then give it ninety days and retest. The 90-day guide goes through all of this properly.
When the goal shifts from “fix it” to “work with it”
At some point for many couples, the question stops being how do we raise his numbers and becomes how do we get one good sperm to one good egg.
That isn’t giving up. It’s a change of strategy, and it’s the part of this field that has improved most dramatically in the last thirty years.
IUI, or intrauterine insemination, puts washed, concentrated sperm directly into the uterus. It’s a reasonable first attempt when the male factor is mild, enough motile sperm survives the wash, your partner’s tubes are clear and her age is on your side. It’s cheaper and far less invasive than IVF, with lower odds per cycle. Below a certain motile count, most clinics won’t recommend it.
Standard IVF puts eggs and sperm together in a dish and lets fertilisation happen. It still needs a reasonable number of functional sperm to work.
ICSI, or intracytoplasmic sperm injection, is where a single sperm is injected directly into a single egg. This is the technique that changed male infertility more than any other, because it removed quantity as the limiting factor. A handful of viable sperm can be enough.
Here’s the caveat most articles skip: ICSI solves the delivery problem, not necessarily the DNA problem. Fertilisation rates are high, but embryo quality and pregnancy still depend on the quality of the sperm itself and, very heavily, on your partner’s age.
It’s also worth knowing that guidelines recommend reserving ICSI for genuine male-factor indications, surgically retrieved sperm, previous fertilisation failure or embryo genetic testing, not as a default upgrade for everyone. It costs more. You’re entitled to ask your clinic why it’s being recommended in your case. We’ve compared the two approaches in detail in ICSI vs conventional IVF insemination, and if you want help reading the numbers a clinic quotes you, IVF success rates explained is worth ten minutes.
One more thing, because it goes unsaid a lot: this is the point where the treatment stops being yours and becomes hers. She takes the injections, she goes through egg retrieval, she carries the physical load of a problem that started on your side of the chart. Most men feel something complicated about that. It’s worth saying out loud rather than carrying quietly.
If there’s no sperm in the sample at all
Start here, because the word does more damage than the diagnosis: azoospermia does not mean no sperm exists. It means none reached the sample.
The split matters enormously. Obstructive azoospermia means sperm is being made and blocked. Non-obstructive means very little or none is being made in the first place. Your FSH level, the size of your testicles, and genetic testing usually point clearly to which one you’re dealing with.
How sperm is retrieved
| Procedure | Taken from | How | Usually used for |
| PESA | Epididymis | Needle, local anaesthetic, minutes | Obstructive |
| MESA | Epididymis | Open microsurgical collection | Obstructive, high yield for freezing |
| TESA | Testicle | Needle aspiration, local anaesthetic | Obstructive, sometimes non-obstructive |
| TESE | Testicle | Small open biopsy | Non-obstructive |
| micro-TESE | Testicle | Microscope-guided search through tissue | Non-obstructive, the current gold standard |
What it’s actually like
This is the part nobody writes about, and it’s what you’re really wondering.
These are day procedures. You go home the same day. The needle-based ones take minutes under local anaesthetic. Micro-TESE is the most involved, and it’s done under general anaesthetic. The surgeon works under a microscope to find the small pockets of tissue still producing sperm, which is why it takes considerably longer.
Afterwards, expect soreness and swelling for a week or two, supportive underwear, no gym or heavy lifting for a couple of weeks. Most men are back at a desk within a few days.
It is, almost universally, less bad than what you’ve been imagining.
The odds, honestly
In non-obstructive azoospermia, sperm is found in roughly 40 to 50% of men. Pooled analysis across studies puts it around 50%; individual centres report figures from 39% to 47%, and the number varies with the underlying cause and with the surgeon’s experience.
In obstructive azoospermia, retrieval succeeds far more often.
Where sperm is found and ICSI goes ahead, published live birth rates run around 24 to 28% per cycle, with cumulative rates across several cycles considerably higher. For example, one large cohort reported nearly 47% cumulative.
Those are hard numbers to read about yourself. But coin-flip odds are not the same as no odds, and you deserve to hear that before you decide anything.
If they don’t find any
This has to be said, because pretending otherwise helps nobody.
Sometimes a retrieval comes back empty. When it does, a second attempt at a higher-volume centre is sometimes worthwhile, and in selected men hormonal treatment beforehand is considered.
And if that door does close, there are still routes to a family that thousands of people take every year: donor sperm, embryo donation, adoption, fostering. These are different roads to the same destination. They are not consolation prizes, and the families they build are not lesser ones.
Freeze what you have
Short and practical, and almost every article on this topic leaves it out.
If there is sperm available now, in an ejaculate or from a retrieval, freezing it is worth serious thought. It protects you against further decline, it can mean not repeating a surgical retrieval later, and it separates your timeline from your partner’s, which matters more than people expect during a long treatment process.
It becomes urgent before cancer treatment, before any testicular surgery, before starting testosterone, and in any man whose counts are visibly falling across successive tests.
The part of this that isn’t medical
Men consistently report shame and guilt toward their partner after this diagnosis. It’s one of the most reliable findings in the small body of research on how men experience infertility. If that’s what you’re feeling, you are having the standard reaction, not a weak one.
A few things worth knowing.
The collection room is awkward for everybody. Everyone in that waiting room knows why everyone else is there. Nobody has ever found it dignified. It doesn’t get less strange, but it does stop mattering.
Your partner is almost certainly not disappointed in you. She’s frightened, and there’s a good chance you’re both saying very little precisely because you’re each trying to protect the other. That protective silence is the single most common thing that goes wrong between couples at this stage.
If you don’t know how to start, borrow a sentence:
“I got the results back. I don’t understand all of it yet. Can we look at it together?”
“I’m not okay about this, but I don’t want you to think I’m pulling away from you.”
And one practical piece of advice from couples who’ve been through it: decide together how often you’ll talk about this. Fertility treatment is long, and left unmanaged it becomes the only subject in the house. Some couples pick one evening a week. It sounds clinical. It saves relationships.
Counselling exists, support specifically for men exists, and both are worth using.
What to ask at your next appointment
Take these with you. Or screenshot them.
- Which of the four situations am I in – low numbers, a blockage, low production, or unexplained?
- Do we know the cause, or is this idiopathic?
- Is anything here reversible, and how long would we wait to find out?
- Do I need hormone testing, genetic testing or an ultrasound before we decide anything?
- Could any medication or supplement I’m taking be contributing?
- Given my numbers and my partner’s age, do we have time to try the less invasive route first?
- If we go to sperm retrieval, how many does this centre perform a year, and what’s your retrieval rate for men like me?
- Should I freeze a sample now?
- What’s the full cost, and what does it cost if the first attempt doesn’t work?

Where this leaves you
Male infertility isn’t one condition with one outcome. It’s a category covering dozens of different problems, and the treatment that matters is the one that matches yours.
Some of this is reversible. Much more of it is workable. A small amount of it isn’t, and even then there’s more than one way to become a father.
Two things change outcomes more than anything else: getting an accurate diagnosis rather than a guessed one, and not making these decisions by yourself.
A diagnosis is a starting point, not a verdict.
Frequently asked questions
Can male infertility be cured?
Sometimes. Blockages, hormone imbalances, infections and varicoceles can often be treated directly. Genetic causes and severe non-obstructive azoospermia usually can’t be reversed, but assisted reproduction means many men in that group still have biological children.
Is a low sperm count permanent?
Not necessarily. It depends entirely on the cause. Counts often improve when a treatable cause is addressed or when significant lifestyle factors change, though improvement takes at least three months to appear on a test. Some men also conceive naturally with low counts.
How long before lifestyle changes show up in a test?
About three months. Sperm takes roughly 72 to 90 days to develop, so a semen analysis today reflects conditions from around three months ago. Don’t retest at six weeks and conclude nothing worked.
Does testosterone therapy cause infertility?
Yes, in effect. Testosterone replacement and anabolic steroids suppress the hormonal signal that drives sperm production, often to zero. It usually reverses after stopping, but recovery can take many months and isn’t guaranteed. Always tell your doctor if you’re taking it.
Do I automatically need ICSI if I have male factor infertility?
No. ICSI is recommended for severe male factor, surgically retrieved sperm, previous fertilisation failure or when embryo genetic testing is planned. For milder cases, IUI or conventional IVF may be appropriate and cost less. Ask why it’s being recommended for you specifically.
Does sperm retrieval hurt?
Less than most men expect. Needle-based procedures take minutes under local anaesthetic; micro-TESE is done under general anaesthetic. Afterwards, expect soreness and swelling for one to two weeks and no heavy lifting, but most men return to desk work within a few days.
What happens if no sperm is found?
A second attempt at a high-volume centre is sometimes worthwhile, occasionally with hormonal treatment beforehand. If retrieval isn’t successful, donor sperm, embryo donation, adoption and fostering remain routes to building a family.
