Fertility & later-life pregnancy

Preconception: the boring list that actually changes outcomes

Five things with real evidence behind them, none of which are sold as a protocol.

Controlled human trials, replicated, with outcomes that matter.

Folate, before you are pregnant

Neural tube closure happens in the first few weeks, usually before a pregnancy is confirmed, which is why folate supplementation is recommended before conception rather than after. This is among the best-established preventive interventions in obstetrics, and it is cheap. Women with a higher-risk history are advised a higher dose by their clinician.

Thyroid, corrected before rather than during

Untreated hypothyroidism is associated with difficulty conceiving and with pregnancy complications, and thyroid requirements rise substantially in early pregnancy. Thyroid autoimmunity — TPO antibodies — matters even when TSH still looks acceptable, because it predicts who will struggle to keep up with that rise. This is why the AZZA panel includes free T4, free T3 and TPO antibodies rather than TSH alone.

Iron, glucose, and body weight

Iron deficiency is extremely common in menstruating women and worsens across pregnancy, when requirements climb steeply; correcting it beforehand is far easier than catching up later. Glycaemic control before conception is associated with lower risk of congenital anomaly in women with diabetes, which is why HbA1c belongs on a preconception panel. Body weight at both extremes affects ovulation and pregnancy risk.

And the part this industry gets wrong

Most hormone and peptide therapy is contraindicated when you are trying to conceive, pregnant or breastfeeding. That includes a great deal of what is marketed to women in exactly this age group for exactly these symptoms. If you are trying, the honest answer is usually that the protocol stops and the boring list above starts. A service that will not tell you that is selling, not treating.

Key points

  • Folate before conception, not after — the window closes early.
  • Thyroid and TPO antibodies matter before pregnancy, not just during.
  • Correct iron and glucose first; both are far harder to fix later.
  • Most hormone and peptide therapy stops when you start trying.
