Infertility: Your Tests and Treatment Journey as Research Data

Every figure in this guide comes from a published source, linked where it appears and kept in CureCircle's evidence base with the source's own words. It is not medical advice. Read on 7 November 2026.

Trying for a baby when it does not happen is one of the most measured experiences there is: cycle tracking, blood tests, scans, a semen analysis, then perhaps rounds of treatment, each with its own numbers and its own hope. Most of that record sits in clinic files and phone apps, and most of the experience, what each round was like, what helped, what it cost in every sense, is never recorded at all. Research on fertility care needs both, from as many people as possible.

How many people it affects

The WHO reported in 2023 that "around 17.5% of the adult population – roughly 1 in 6 worldwide – experience infertility".

The records worth keeping

NICE's guideline on fertility problems describes the tests that leave records:

• A blood test to confirm ovulation: serum progesterone in the mid-luteal phase, day 21 of a 28-day cycle.
• Ovarian reserve: an AMH blood test or an antral follicle count on ultrasound, used to predict the response to treatment.
• A tube test: hysterosalpingography (HSG) to screen for tubal occlusion.
• A semen analysis, with a repeat confirmatory test if the first is abnormal.

Treatment records (each cycle, the medicines and doses, the scans and the outcome) and cycle tracking from an app complete the picture. If you do not have them, ask your clinic for a copy.

What sharing it is worth

CureCircle values every contribution with a public benchmark built from what health data has sold for. A complete infertility story with the records the guideline lists comes to about $62 per licence on the benchmark today. With 90 days of cycle tracking added, it comes to about $335 per licence. Every line and its source is on the infertility page.

A licence is not a one-off sale: the same de-identified story can be licensed to several research teams, and you earn a share each time.

Private by design

Fertility is private. Nothing that identifies you is shared: no names, no place finer than a country, no exact dates, and you read the de-identified summary before anything goes anywhere. Partners can each share their own part. You can withdraw at any time. How de-identification works, and what it cannot promise.
