Trying for a baby: fertility basics

Deciding to try for a baby is one of those quietly enormous moments — exciting, a little scary, and often followed immediately by a hundred practical questions. How long will it take? What should we be doing differently? When should we worry? Here’s a calm tour of the basics, minus the pressure.

How conception actually works. Once a month or so, one of your ovaries releases an egg (ovulation). The egg lives for only about 12 to 24 hours, but sperm can survive inside you for up to five days — so the real window for conception, your fertile window, is roughly the five days before ovulation plus the day itself. Sex every two to three days across your cycle covers that window without turning it into a scheduling project; if you’d rather target it, an ovulation article’s worth of tracking methods can help you find your fertile days.

How long it usually takes. This is the number that surprises most people: conception often takes months, not weeks, even when everything is working perfectly. Each cycle offers roughly a one-in-four to one-in-five chance for younger couples, and the odds compound from there — most couples under 35 conceive within a year, the majority of those within six months. A few cycles of “not yet” is not a sign that something is wrong; it’s the ordinary maths of conception.

Getting your body ready. A few things genuinely earn their reputation:

• Folic acid — start a supplement (usually with iodine, or as a pregnancy multivitamin) at least a month before trying, because it protects your baby’s developing spine in the earliest weeks, often before you know you’re pregnant.
• A preconception check-up with your GP — a short visit that covers your medications (some need changing before pregnancy), any health conditions, your vaccination status (rubella and chickenpox immunity matter), and a cervical screening check if you’re due. This is also the natural moment to ask about genetic carrier screening, which is best done before pregnancy.
• The lifestyle pair — not smoking and not drinking alcohol, for both of you. Sperm take about three months to make, so a partner’s habits now shape the sperm that will matter later. Moving your body regularly and eating reasonably well help both of you; perfection is not required.

Coming off contraception. For most methods — the pill, the ring, an IUD, the implant — fertility returns quickly once you stop, often within the first cycle or two, and there’s no need to “flush anything out of your system” before trying. The exception is the contraceptive injection, which can take many months to wear off after the last dose. Your first few natural cycles may be irregular while your body finds its rhythm again, which makes ovulation harder to predict — annoying, but normal. If your period hasn’t returned within about three months of stopping, check in with your GP.

A quick myth-clearing. No sex position improves your chances; sperm reach the cervix within minutes regardless. Lying with your legs up afterwards is harmless but unnecessary. Orgasm is lovely but not required for conception. And having sex every single day doesn’t beat every two to three days — it just adds pressure. The evidence-backed levers really are the unglamorous ones: timing, folic acid, and the lifestyle basics.

What’s true for partners. Fertility is a two-person story — roughly as many conception difficulties trace to sperm as to eggs. The good news is that the same boring advice works: no smoking, minimal alcohol, a healthy-ish weight, and keeping things cool (saunas and hot baths aren’t sperm’s friends). No supplements or gadgets required, whatever the ads say.

About age — honestly. Fertility does decline with age, more noticeably from the mid-thirties for eggs and more gently for sperm. That’s worth knowing when you’re deciding when to start trying, but it isn’t a verdict on any individual: plenty of people conceive easily at 38 and some 28-year-olds need help. If you’re older and it’s taking a while, the main practical difference is simply to seek advice sooner rather than waiting the full year.

The emotional side. Trying for a baby has a way of shrinking life down to two-week intervals: the wait to ovulate, then the wait to test. A negative test can feel like real grief, and it’s common for sex-on-schedule to put strain on even solid relationships. Be kind to yourselves: keep some parts of life that have nothing to do with conceiving, agree together on how much tracking feels sane, and remember that a negative month is not a failure by either of you.

When to get help. The standard advice: see your GP if you’ve been trying for 12 months without success — or 6 months if you’re 35 or over — or straight away if your periods are very irregular or absent, you have a condition like PCOS or endometriosis, or either of you has a known reason to be concerned. “Getting help” starts small: a chat, some simple tests for both of you. And seeking it early isn’t pessimism — it’s just information, and information is on your side.

However this chapter goes — quick, slow, or complicated — your GP is your first port of call, and there’s more support in Australia than most people realise. Start the folic acid, book that check-up, and be gentle with yourselves. You’ve already begun.
