Conditions
Azoospermia
Azoospermia means no sperm were found in the ejaculate. It needs a prompt repeat and specialist assessment, not a supplement or a home strip.

Short answer
Azoospermia means the laboratory found no sperm in the ejaculate. NICE says a repeat test should be done as soon as possible, rather than after the usual three months. It can be caused by a blockage or by sperm not being produced. Those causes are distinguished by examination and tests. SemenBoost cannot tell which one you have.
Key takeaways
- One report of “no sperm seen” still needs a careful repeat. Cryptozoospermia means sperm appeared only after the sample was concentrated.
- Do not start testosterone. It can suppress sperm production.
- Sperm retrieval and assisted reproduction are specialist procedures when they are appropriate.
- A home sperm test is the wrong tool for this finding.
Two broad groups
Obstructive azoospermia means sperm are being made but do not reach the ejaculate. Prior vasectomy, absent vas deferens, and some infections sit in this group. Non-obstructive azoospermia means production is severely impaired. Hormone results and testicular size help the clinician separate them. The AUA/ASRM guideline covers evaluation, including when genetic tests are relevant. Those criteria should be applied by a specialist who has your results.
Why the repeat is urgent
A labelling error, a spilled sample, or sperm so scarce they were missed can imitate azoospermia. NICE still treats the finding as a gross deficiency and wants it confirmed quickly. Waiting three months “to see” is the advice for less severe abnormalities, not for this one.
What not to do first
CoQ10, carnitine, zinc and similar products have been studied in men with abnormal semen parameters. They are not a treatment for uninvestigated azoospermia. If you are taking testosterone or anabolic steroids, tell the clinician before you change the dose. Stopping prescribed testosterone can be the right fertility discussion and the wrong thing to do without the prescriber, especially if it was started for hypogonadism.
