Few pieces of paper land as hard as a semen analysis that reads azoospermia — no sperm seen. Couples usually arrive at this page in the first 48 hours after that result, searching for something they can do. Here is the honest version, written for people in the US and Canada who are about to start a urology workup.

The honest part first: no supplement creates sperm
We will say this plainly, because a lot of the internet will not. No dietary supplement — ours included — can produce sperm where the testes are not making any, and none can clear a blocked pathway. Azoospermia is a structural or hormonal medical question, and the answer to it comes from a urologist or a male-fertility specialist, not from a capsule. Anyone promising otherwise is selling you a promise the evidence does not support.
What AGO products are designed to do is far narrower: support everyday male reproductive wellness through the months around a workup, alongside whatever your specialist decides. If that framing feels less exciting than the ads you have seen, that is the point — see what is actually in our products and who should ask a doctor first.
One more practical note: ask for a repeat test. Specialists routinely confirm azoospermia on a second sample, often weeks later, and after a centrifuged pellet review. A single result is not a diagnosis.
Obstructive vs non-obstructive — the distinction that changes everything
Your specialist will be working out which of two very different situations you are in, and the difference decides the whole plan:
- Obstructive azoospermia — sperm are being produced, but the pathway out is blocked or absent (previous vasectomy, infection, congenital absence of the vas deferens, surgical scarring). Sperm can often be retrieved surgically for ICSI.
- Non-obstructive azoospermia — production itself is impaired, for hormonal, genetic or testicular reasons. Here the workup usually includes FSH, LH and testosterone bloodwork, karyotype and Y-chromosome microdeletion testing, and often a micro-TESE discussion.
Related male-factor conditions worth reading in parallel: varicocele, and the broader picture in male fertility and sperm health. If a later analysis shows very low but present counts rather than zero, that is a different conversation — see low sperm count and motility and morphology and DNA fragmentation.

The AGO combo men use through the 90-day window around a workup
Sperm take roughly three months to develop, which is why specialists ask about the last 90 days at the first appointment. If a retrieval or a repeat analysis is scheduled two or three months out, that window is real time you can use for everyday wellness habits — without expecting it to change a diagnosis.
- AGO Dad — the base of the his side, designed to support everyday male reproductive wellness across that window.
- Sea Oyster (Hàu Biển) AGO — the usual pairing with Dad. How the two differ: AGO Dad vs Sea Oyster. For everyday energy and stamina alongside a stressful workup, see the vitality guide.
- Already on a men’s multivitamin? Read AGO Dad vs a men’s multivitamin before stacking both.
- If he is over 40, the everyday-wellness case is the same: male fertility after 40.
- Her side does not pause. If ICSI is on the table, her egg-side window runs at the same time — AGO Mom, and the pairing in the Mom + Dad his-and-hers combo. When both partners have a finding, see this guide.
Start both sides the same day. Couples lose months queueing his plan behind hers.
Rules for taking anything alongside a urology workup or a retrieval
This is the section to actually follow, because a retrieval is surgery and hormonal testing is easy to muddy.
- Tell the urologist and the fertility clinic what he takes, before testing. Photograph the labels or bring the bottles — “some herbal thing” is not a useful answer.
- If they say stop, stop. That instruction outranks anything on this page.
- TESE and micro-TESE involve anaesthesia. Ask well in advance what to pause and how many days beforehand.
- Never take testosterone or a “T-booster” while trying to conceive unless a specialist has prescribed it — exogenous testosterone suppresses sperm production. If he is already on it, tell the urologist immediately rather than stopping on your own.
- Skip mega-dose stacks from three brands at once. More products is not a better plan — see how to stack sensibly and how long to take them.
What to ask the specialist — and what to sort out at home
The questions below save couples the most time and money in the US and Canada:
- “Is this obstructive or non-obstructive, and what testing decides that?” Ask for the bloodwork and genetic panel by name.
- “Should we repeat the analysis, and when?” Confirmation on a second sample is standard.
- “If sperm are retrieved, what happens the same day — fresh ICSI or freezing?” This determines whether her cycle has to be synchronised.
- “What are the retrieval odds in our situation, and what is the plan if nothing is found?” Donor sperm and adoption deserve to be discussed calmly, early, not in a crisis.
- “What is quoted, and what is extra?” Retrieval, ICSI, freezing and storage are often billed separately — the same money conversation as IVF and IUI prep and waiting for IVF.
At home: protect sleep, keep alcohol modest, and be gentle with each other — this result hits men hard and they rarely say so. If the plan moves to a transfer later, prep is separate: the FET combo.
