Almost nobody starts IVF the week they decide on it. In the US there is usually a stretch of saving, insurance paperwork or employer-benefit checks first; in Canada, publicly funded programs often come with a waitlist on top of the clinic’s own scheduling. So couples end up in a strange in-between: the decision is made, but the calendar is empty. This guide is about using that window well — and the daily AGO combo couples take while they wait.

Why the wait feels wasted — and why it is not
Waiting is the part nobody prepares you for. The referral is in, the funding or the savings plan is moving, and there is nothing to do. But the biology does not pause:
- Egg cells mature over roughly three months before the cycle they are retrieved in — so the months before your start date overlap with the eggs your clinic will eventually work with.
- Sperm cells run on a similar timeline, which is why the male side should start on the same day, not later — see male fertility and sperm health.
- Everyday habits are easier to change now than during a medicated cycle, when you will have enough to think about.
- Some couples conceive during the wait. It is not the plan, but it is a reason to keep timing intercourse rather than putting life on hold.
What a supplement can and cannot do before IVF
Being blunt about this matters more than a sales pitch. No dietary supplement improves IVF success rates, changes how many eggs are retrieved, improves implantation, replaces stimulation medication, or shortens a waitlist. Anyone promising that is not being straight with you.
What AGO products are: dietary supplements designed to support everyday preconception, cycle and sperm-cell wellness — the daily-nutrition layer under whatever your clinic does next. Two non-negotiable rules while you are in a clinic pathway: take every label to your fertility team before starting, and if the clinic asks you to stop something, stop it. That applies at the point your cycle actually begins too — see the IVF and IUI prep couple kit.
What to sort out while you wait — a short list
- Confirm where you actually are in the queue. Ask for an expected window in writing, and ask what would move you up or push you back.
- Get every test done early. Bloods, a repeat semen analysis, and any imaging — an out-of-date result is a classic reason a start date slips.
- Ask whether anything structural needs handling first, such as a hydrosalpinx or a fibroid affecting the cavity — see blocked tubes and the IVF route and fibroids and getting pregnant.
- Sort the money conversation once, so it is not running in the background every day.
- Protect your relationship and your sleep. Waiting is a mental-health window as much as a medical one — see stress and fertility and sleep, hormones and fertility.

The AGO combo couples use during the wait
Once your fertility team has seen the labels, this is the routine most couples settle on for the months before a start date:
- AGO Mom — her daily base, chosen to support everyday egg-cell and preconception wellness across the three-month window; see AGO Mom for egg quality support and supplements before IVF or IUI.
- AGO Eva — added for hormonal balance and cycle comfort when cycles are irregular; the difference is explained in Mom vs Eva.
- AGO Dad — his daily base for sperm-cell wellness over the same 90 days; see AGO Dad for count and motility.
- Hàu Biển (AGO Sea Oyster) — the companion many men add for everyday male vitality; compared in Dad vs Sea Oyster.
- AGO Tumor — added only when fibroids or uterine concerns are part of the picture; see AGO Tumor explained.

How to start — and your free personalized plan
- Step 1: Ask your clinic for a realistic start window, and write the date down — that is what your 90 days count backwards from.
- Step 2: Clear the labels with your fertility team or pharmacist before the first capsule.
- Step 3: Start AGO Mom and AGO Dad on the same day — both windows, one calendar.
- Step 4: Add AGO Eva for cycle comfort, Hàu Biển on his side, or AGO Tumor if uterine concerns apply.
- Step 5: When your cycle starts, hand the list to your nurse and follow the clinic exactly — what happens next is covered in the two-week wait guide and, for a frozen cycle, FET prep.
