Fertility Factors Checklist
Fertility can only be assessed by a doctor, with tests for both partners. This page does not estimate a "fertility age" or your chance of pregnancy. It counts factors the NHS links with fertility and shows when the NHS suggests seeing a GP.
Before you start
Method : Fertility Factors Checklist — a custom points score written by this site. Each answer adds or subtracts the points shown in the Methodology table below.
Validation : Unvalidated. The points have never been tested against any laboratory measurement or health outcome, and the result is not an age.
Review : not reviewed by a qualified clinician. Educational only — not a diagnosis or a medical test.
The NHS suggests seeing a GP if you haven't conceived after a year of trying, or sooner if you're a woman aged 36 or over or already aware of possible fertility problems.

Methodology & assumptions
Your score is the sum of the points below. The weights are our own judgement. The old version added made-up years for AMH levels, treatments, pregnancy and contraceptive history, scored sexes differently and gave a "fertility age". Lab results and medical history need a doctor, so those were removed with the age output.
| Factor | Answer | Points |
|---|---|---|
| Smoking (you or partner) | No | 0 |
| Yes | +2 | |
| Alcohol (drinks a week) | None | 0 |
| 1–7 | 0 | |
| 8–14 | +1 | |
| More than 14 | +2 | |
| Body mass index (BMI, kg/m²) | Under 18.5 | +1 |
| 18.5–29.9 | 0 | |
| 30 or more | +2 | |
| Periods (if applicable) | Not applicable / regular | 0 |
| Irregular or absent | +2 | |
| Time trying to conceive | Not trying / under 6 months | 0 |
| 6–12 months | +1 | |
| More than a year | +2 |
Worked examples
Smoker, more than 14 drinks a week, BMI 31, irregular periods, trying more than a year: 2 + 2 + 2 + 2 + 2 = +10 points.
Non-smoker, light drinking, BMI 23, regular periods, not yet trying: 0 points.
Understanding your result
This counts factors you reported. It is not a fertility test, not a chance of pregnancy and not an age. Age itself affects fertility, but this score cannot say by how much for you. Health-agency guidance linked below is general and based on populations, not on this score.
