Extended hormone mapping

Serial progesterone mapping (P+3 through P+11) is sometimes used to look at the shape of the luteal curve rather than a single point. Be aware of what this can and cannot establish: a progesterone value above 3 ng/mL is evidence that ovulation recently occurred, but neither a single draw nor a series grades luteal “quality” in a way current guidelines accept, and luteal phase deficiency is not established as an independent cause of infertility. Filia’s cycle-timed series draw progesterone at Peak +7, and Cycle Complete also at Peak +5 and Peak +9, timed from the Peak you log; Filia does not sell a P+3 to P+11 series.

Estradiol across phases adds context on follicular development and luteal support, but it swings widely across the cycle and has no single optimal value. Early-follicular estradiol is interpreted together with FSH on cycle days 2–4, not on its own.

DHEA-S: A stable adrenal androgen marker, useful when clinical androgen excess or an adrenal source is suspected. It is not needed for every user.

SHBG: Low SHBG is associated with insulin resistance and PCOS. It contextualizes total testosterone — without it, you can’t tell whether free testosterone is actually elevated.

17-Hydroxyprogesterone: An 8 AM draw screens for non-classic congenital adrenal hyperplasia, a treatable cause of anovulation. It is indicated only when NCAH is actually suspected, not as part of a broad panel. Filia does not sell it — ask your clinician whether your history warrants it.
