Modern Fertility, reviewed.

What we tested.

We ran the Modern Fertility Hormone Test in February 2026, ordered from the consumer site and shipped overnight. The kit arrived in a slim cardboard sleeve with a single dried-blood-spot collection card, two lancets, alcohol wipes and an instructions card calibrated to a phone-friendly checklist. The unboxing is the most considered we've seen in the category — every element exists to lower the friction of the cycle-day-three blood draw a woman will likely do at her kitchen table, possibly while bleeding, possibly slightly anxious.

The app reminded us when cycle day three landed (we'd entered cycle data at checkout). The finger-prick took six minutes including the photographed steps. We dropped the prepaid envelope at a USPS mailbox the same morning. Results landed in the app eight days later — one day faster than the published estimate.

The result UI is the brand's clearest differentiator. Each of the seven hormones gets its own panel — a value with units, a personalised reference range based on age and cycle day, a "what your number may mean" explainer written at a reading level that lands for a non-clinical reader without being condescending. The AMH panel includes a percentile chart against age-matched peers; the FSH panel includes a "what would change next cycle" callout. Whoever does the editorial inside the app is doing it well.

"It's a snapshot of reproductive endocrinology, taken on the right day, framed in the right context."

Where Modern Fertility genuinely shines.

• Cycle-day timing baked into the product — the panel is calibrated for day-3 timing, the app reminds you, the result interpretation factors it in. No other at-home hormone test does this well.
• Companion app + community — a private, woman-only forum where members compare numbers and share what they did next. The single best peer-context layer in any consumer testing brand we've reviewed.
• 1-on-1 fertility consult included — every panel includes a 30-minute video consult with a fertility nurse or coach, run through the app. Worth the price of the test on its own.
• Reporting written for a real woman — none of the wellness-mag floppiness, none of the clinical opacity. The editorial inside the app is the brand's biggest moat.
• Ovulation tracking integration — for women using ovulation predictor kits or basal body temperature, Modern Fertility's tools layer the hormone snapshot onto the cycle picture cleanly.

Where it loses points.

• Cycle-day timing matters — a lot — if you mistime the draw (most often, drawing on day 5 instead of day 3 because of confusion about when "day 1" really starts), some markers may read meaningfully different. The app warns you, but the warning relies on you having logged your cycle data correctly.
• Single-point-in-time snapshot — one panel tells you what your hormones look like on one day. AMH is relatively stable over months; FSH, LH, estradiol fluctuate. For a woman wanting a multi-cycle picture, you'd need to retest.
• Narrower than a full comprehensive panel — seven hormones, no thyroid-beyond-TSH detail, no vitamin or nutrient markers, no metabolic context. This is a fertility lens, not a wellness lens.
• Not available in New York — regulatory restriction we expect to persist. New York women would route to Modern Fertility's clinic partners or to an in-clinic draw alternative.
• "Fertility score" framing can over-promise — the app's summary view can read more deterministic than the underlying hormones actually are. Fertility is multifactorial; a panel is one input, not the answer.

Who it's best for.

• The "I'm 32 and starting to think about it" woman — wants a baseline AMH and an FSH picture before life decisions get serious. Modern Fertility was built for this woman.
• The woman with irregular cycles — wants to know if PCOS-pattern hormones are showing up, or if the irregularity has another explanation worth discussing with a clinician.
• The IVF re-entry woman — already did a round, wants a current snapshot before the next clinic consult.
• The "I'm in early perimenopause and confused" woman — wants to see what FSH and estradiol are doing at this particular moment, with proper cycle-day context.

Who it's not for.

• Women wanting a comprehensive wellness panel — this isn't that. Function Health or InsideTracker fit better.
• Women not actively cycling — postpartum without a return of cycles, or fully postmenopausal — the day-3 timing model loses its anchor.
• Women in New York — regulatory unavailable. Quest Health's hormone panel is the closest alternative.

Price and what's included.

Modern Fertility runs a tight, focused catalogue. The headline product is the Hormone Test at $159 (or $179 with the optional consult upgrade depending on tier). What's actually in the panel:

Cycle-day-three timing applies to FSH, LH and estradiol — the markers that fluctuate across the menstrual cycle. AMH, prolactin, TSH and free T4 are less timing-dependent and can be drawn on most cycle days, but the panel as a whole is calibrated for day 3 because that's where the cycle-sensitive markers are most interpretable.

How it compares to Everlywell's Fertility Test.

The closest sibling in the at-home category is Everlywell's Women's Health or Fertility Test panels. Both run dried-blood-spot collection, both use accredited partner labs. The differences are where Modern Fertility earns the 0.4-point gap on our framework.

The honest read: Everlywell wins on marker count at the same price. Modern Fertility wins on every dimension that actually matters for the question being asked — cycle-day-aware testing, app-based education, included clinician consult, community context. For a deeper look at how the two stack across more dimensions, see best hormone tests for women and the broader at-home tests comparison.

The case against.

Three honest critiques.

The "fertility score" abstraction can flatten complexity. Modern Fertility's app sometimes resolves seven hormone numbers into a single qualitative score (e.g. "your hormone levels are in a typical range for your age"). For most women this is reassuring and correct. For the woman whose AMH is borderline-low for her age but whose FSH looks fine, the score may obscure a conversation worth having with a fertility specialist.

Snapshot ≠ trajectory. One day-3 draw tells you about that cycle. Hormones move month-to-month, and meaningfully across years. The panel is a credible input — not the whole picture. Modern Fertility says this in the disclaimers; the marketing tone can softpedal it.

Not a replacement for a fertility consult. The included 30-minute consult is excellent. It is not a fertility workup. For women actively trying to conceive without success after six to twelve months, an in-clinic REI consult and ultrasound is the appropriate next step.

Should you actually buy it?

For women whose central question is fertility — and who want an at-home, mail-in, cycle-day-aware panel with a clinician consult included — yes. Modern Fertility is the best dedicated tool in the U.S. category for this exact woman. The $159 is competitive against what an out-of-pocket clinic draw would cost, and the app layer is genuinely better than what most clinics will hand you.

For women whose question is broader — "what's going on with my health overall" — Function Health or an InsideTracker panel is the right starting point, with Modern Fertility added later if fertility-specific questions surface.
