“Should we both take something?” is one of the most common questions couples ask when they start trying to conceive. Fertility is a team effort: roughly a third of cases involve a female factor, a third a male factor, and the rest both or unexplained, according to commonly cited clinical overviews. That is why a doctor will often evaluate both partners.
This is a quick framework for deciding who starts what, and when. For the full plan, see fertility supplements for couples.
1. Start with both evaluations
Before buying anything, ask your doctor about her cycle and ovulation and a semen analysis for him. A baseline tells you which side you are supporting and gives you something to re-check after about three months.
2. When she may start first
If cycles are irregular, ovulation is unclear or she is over 35, women often begin a TTC-focused formula early. AGO Mom is designed to support female reproductive wellness; see the ovulation support guide.
3. When he should start at the same time
Sperm takes about 72–90 days to develop, so starting early matters. If his semen analysis shows low count or motility, or if he has heat, smoking or medication factors, AGO Dad is designed to support male reproductive wellness — alongside a urologist’s advice. Our male fertility checklist helps compare options.
4. When a combo makes sense
Many couples choose the his-and-hers starter combo so both sides run on the same 90-day clock. See our 90-day plan and pricing guide to budget it.
5. Build a simple shared plan
Pick a start date, put both bottles in the same routine, avoid doubling up with existing vitamins, and schedule a re-check at about 90 days. If you are unsure, get a free personalized plan or browse the range.
FAQ
Should both partners take fertility supplements?
Not necessarily. Many couples start with evaluations for both partners and then choose support for the person or people it fits. Your doctor can help you decide.
Can I take a fertility supplement if my partner does not?
Yes. Each partner can decide separately, though male factor is involved in a meaningful share of cases, so a semen analysis is worth discussing.
How long before we see a difference?
Plan on about 90 days for a fair review because egg and sperm development both take around three months. No outcome is guaranteed.
Is there a combo for couples?
AGO offers a his-and-hers combination of AGO Mom and AGO Dad. The care team can suggest what fits your situation.
