For doctors: from semen analysis to IUI, IVF or ICSI, and honest azoospermia counselling
For doctors: read every line of the semen analysis, but decide on the total motile count, confirmed on a repeat sample after correcting what is correctable. Then climb down a ladder: timed intercourse, IUI judged on the post-wash count, IVF, then ICSI, alongside the female workup. Confirm azoospermia before naming it, and counsel with a plan, not a verdict.

Who this article is for
This article is for medical professionals, especially young gynaecologists starting in fertility practice. It was recorded on World IVF Day and is shared colleague to colleague; it does not replace your own clinical judgement or local guidelines. Patients will find what a semen report shows and azoospermia explained more useful.
How should you read each line of a semen analysis?
- Volume: about one and a half millilitres at the lower limit. If volume is low and the count low or zero, first ask whether part of the sample was spilt. Then think of obstruction, congenital absence of the vas, or retrograde ejaculation, where urine passed straight after ejaculation shows the sperm.
- Concentration: about 15 million per ml at the lower limit. WHO editions differ a little, so check which one your lab uses. Concentration times volume gives the total count, which says more about testicular output.
- Motility: total motility counts every sperm that moves, including one twitching in place, so it flatters the report. Progressive motility, around thirty per cent at the lower limit, is the figure to read. Fifty per cent total with ten per cent progressive is a poor sample.
- Morphology: normal forms on strict criteria, about four per cent at the lower limit. It is the most lab-dependent line, so treat it as supporting information, never the sole reason for a big decision.
Remember where these limits come from: men who recently fathered a child. A man below a limit is not proven infertile, and a man above it is not proven fertile.
Which number should drive the decision?
The total motile count: volume times concentration times motility. Use progressive motility and you get the progressive motile count, the honest version. For IUI, also ask for the post-wash count, because what survives the lab's preparation is what you place in the uterus.
Why should you never decide on one sample?
A fever or a bad month wrecks a report, and spermatogenesis takes about three months. So correct what is correctable first: infection, thyroid disease, and the testosterone he picked up at the gym, which quietly shuts down his own production. In hypogonadotropic hypogonadism, gonadotropins can genuinely restore production. Varicocele repair helps only selected men, and that evidence is still argued. Then re-test before escalating.
How do you turn the count into IUI, IVF or ICSI?
These are practical working thresholds. There is no single agreed cut-off, guidelines differ, and your judgement outranks any number here. Think of a ladder, and at every rung ask how many motile sperm are needed and how far they must travel.
- Timed intercourse asks the most: millions of sperm and the whole journey through cervix, uterus and tube. Above about 20 million total motile count, with a normal female workup, it is fair to offer. Towards 10 million and below, stop selling more months on a route the sperm cannot manage.
- IUI bypasses the cervix, but it cannot create sperm, so the honest cut-off sits on the washed sample. Above roughly 5 million post-wash progressive motile sperm it is worth doing; between 1 and 5 million the results fall away, so say so plainly; below about 1 million most of us would not attempt it. A futile IUI is not kindness. It costs money, her cycles, and time you cannot give back.
- IVF deletes the journey. You need tens of thousands of motile sperm per egg, not millions crossing several centimetres.
- ICSI is for very low counts, very poor motility or morphology, surgically retrieved sperm, or failed fertilisation before. It turns a problem of numbers into a problem of finding one viable sperm.
Never read the semen report by itself. The same count means one thing when she is 26 with open tubes, and another when she is 38 with few eggs left; there, you skip rungs. Patient guides: IUI for a low sperm count, IVF with ICSI.
How should azoospermia be confirmed and investigated?
Before you say the word to anybody, be certain. Confirm on a second sample, and ask the lab to centrifuge it and examine the pellet; that extended search often finds a few sperm, and a few sperm change everything. Then check FSH with testosterone, testicular volume and both vasa. Normal FSH with normal testicular size suggests obstruction, so sperm are being made. High FSH with small, soft testes suggests production failure.
Order genetic tests before you plan surgery: a karyotype, a Y chromosome microdeletion study, and cystic fibrosis testing when both vasa are absent. Certain complete Y deletions predict that surgery will find nothing, and knowing that spares a man an operation.
Even in production failure, a meaningful proportion of men still have small pockets of sperm production inside the testis. Micro-TESE looks for them under an operating microscope, selecting the healthier tubules instead of taking tissue blindly.
How do you break the news of azoospermia?
Both partners in the room, door shut, phone silent; never on the telephone, never by handing over the report. Say it early and plainly: in this sample we did not find any sperm. Then stop, and let the silence sit. It will feel unbearable to you, and it is necessary for them.
- Never say there is no sperm so they cannot have children. It is untrue, and you can never take it back.
- Blame no one. Do not blame him, and do not let his family blame her; in many families she has carried that blame for years.
- Say the sentence he is too embarrassed to ask: this has nothing to do with your manhood or your sexual function.
- Give a plan, not a verdict. This is the first step, not the last: what we know, what we do not know yet, and the appointment next week. They will not remember a word after "no sperm", so give it in writing.
What should you say honestly about sperm retrieval?
The advantage is real: if sperm are found, with ICSI he can become the biological father of his own child. But say plainly, at the first conversation and not after a failed cycle, that the chances in these cases are generally lower, because retrieved sperm are often of poorer quality. Tell them too that some causes of male infertility are inherited and can pass to a son, who may face the same problem as an adult, so genetic testing and counselling belong before the cycle. Juniors fear that naming limits drives couples away. It does the opposite: honesty builds trust that survives a failed cycle.
Then lay out the options: correctable causes, surgical retrieval with ICSI, donor sperm and adoption. Recommend nothing that day.
Where does donor insemination fit?
Donor IUI is under-discussed. It fits where retrieval has failed or is declined, where there is a serious inheritable condition, and often where the couple cannot afford retrieval plus ICSI. Sperm from a registered assisted reproduction bank is screened for infection and genetic conditions; she carries her own pregnancy, and the child is genetically hers; and the cost is a fraction of retrieval with ICSI. Cost is a clinical variable. Use a registered bank, with the consent and documentation the law requires, and confirm her tubes are open and she ovulates.
Raise it at the follow-up, not on the day you break the news, and ask permission first. Place it in the middle of the list, not at the end as a consolation prize. Let them talk alone, and tell them no decision is needed that day. Not long ago these men were told nothing could be done. Today there is a ladder, and our work is to know honestly which rung this couple stands on.

Questions colleagues ask
What is the total motile count, and why does it matter?
Volume times concentration times motility; with progressive motility it becomes the progressive motile count, the more honest version. It is the number that drives the decision.
What post-wash count is needed before offering IUI?
As a working threshold, above roughly five million post-wash progressive motile sperm. Between one and five million results fall away; below about one million most clinicians would not attempt it. Guidelines differ.
Should one semen analysis decide treatment?
No. A fever can wreck a report, and spermatogenesis takes about three months. Correct infection, thyroid disease or exogenous testosterone, then repeat the test before escalating.
Which tests come before surgical sperm retrieval in azoospermia?
Confirm it on a second, centrifuged sample; check FSH, testosterone, testicular volume and both vasa; then order a karyotype and a Y microdeletion study, with cystic fibrosis testing when both vasa are absent.
How should azoospermia be disclosed to a couple?
In person, with both partners present, never by telephone. Say it early and plainly, then pause. Never say they cannot have children, blame neither partner, and give a written plan.
