Best Fertility Tests in 2026

Anti-Mullerian Hormone (AMH) is the single most informative marker for ovarian reserve, indicating how many eggs remain. Unlike FSH, which fluctuates throughout your cycle, AMH stays relatively stable and can be tested any day. A complete picture requires FSH, LH, and estradiol tested on day 3 of your cycle, but AMH alone provides useful baseline information.

Leading at-home kits like Legacy and Fellow use CLIA-certified labs and achieve accuracy comparable to clinic-based analysis. They measure the WHO-standard parameters:concentration, motility, morphology, and volume. The key limitation is sample handling, since sperm viability decreases over time. Services with fast overnight shipping and proper temperature control produce the most reliable results.

These tests measure biological markers associated with fertility, but they can't predict pregnancy timing or success. Normal AMH and FSH don't guarantee easy conception, and lower values don't mean you can't conceive. Think of these as screening tools that identify whether further clinical evaluation makes sense, not crystal balls for pregnancy outcomes.

Consider baseline testing in your late 20s or early 30s if you're planning to delay pregnancy. AMH and FSH give you data to inform timing decisions. That said, there's no wrong time to test. Many providers serve women from late teens through early 40s. The value depends on whether the information would change your plans.

No. At-home tests are screening tools, not diagnostic workups. If results show concerning values, or if you've been trying to conceive for 12 months (6 months if over 35) without success, see a reproductive endocrinologist. Clinic-based evaluation includes ultrasound to count follicles, which no at-home test can replicate.
