Trying for a baby after 35 comes wrapped in unhelpful labels and scary headlines. Let's swap the panic for understanding, because knowing how your fertility hormones work helps you make good decisions.

The hormones that matter:

• FSH and oestrogen drive each cycle's egg development. As you age, the ovaries respond less efficiently, and cycles can change.
• AMH (anti-Müllerian hormone) reflects your remaining egg quantity (ovarian reserve). It's a useful marker, but it does not measure egg quality or guarantee whether you'll conceive — an important nuance often misunderstood.
• LH surges to trigger ovulation — pinpointing this (via tracking or ovulation tests) helps you time things.
• Progesterone after ovulation supports a potential pregnancy.

What changes with age: both egg quantity and average egg quality decline gradually, more noticeably after the mid-to-late 30s. That means it can take longer to conceive and miscarriage risk rises somewhat — but plenty of women conceive healthily in their late 30s and beyond.

What's within your control:

• Track your cycle and ovulation to time intercourse to your fertile window (the few days before and including ovulation).
• Support general health: balanced nutrition, healthy weight, not smoking, limiting alcohol, managing stress and sleep — all matter for fertility.
• Sort the basics: folic acid before and in early pregnancy, and a preconception check-up.

When to seek help — don't wait too long: general guidance is to see a doctor after 6 months of trying if you're over 35 (versus 12 months if younger), or sooner if you have irregular cycles, known conditions like PCOS or endometriosis, or other concerns. Earlier assessment simply gives you more options.

The mindset that helps: age is one factor, not a verdict. Understand your hormones, track your cycle, look after your health, and get timely support — that's a plan, not a panic.

Common questions

What does AMH tell you?

AMH reflects your egg quantity (ovarian reserve), not egg quality, and it doesn't predict for certain whether you'll conceive. It's one piece of the picture, not a verdict.

When should I see a doctor about conceiving over 35?

Generally after 6 months of trying if you're over 35 (versus 12 months if younger), or sooner with irregular cycles or known conditions like PCOS or endometriosis.
