Definition
What Progesterone measures
Progesterone is produced mainly by the corpus luteum after ovulation and in smaller amounts by the adrenal glands. The number is almost meaningless without cycle timing.

Why it matters
How clinicians usually read it
SiPhox keeps it on the women's hormone set. On a Tasso+ SST it is available; interpreting it still belongs with cycle day or hormone therapy context.
When it reads low
A lower value can mean
A lower progesterone is expected in the follicular phase, in men, and after menopause. In the mid-luteal window it can mark a weaker ovulation.
When it reads high
A higher value can mean
A higher progesterone is expected after ovulation or with some hormone therapies. Unexpected elevations need a clinical look at timing and supplements.
Questions for a clinician
Bring the number into a real conversation
01
What cycle day or hormone protocol was this drawn on?
02
Is this a luteal-phase check or a random screen?
03
Would a timed redraw be more useful than this value?
