Overview
- The PLOS One paper, published Wednesday, September 2, 2026, reports three complementary studies using urine hormone assays and cycle-phase surveys that link higher fertility with stronger desire for visible luxury items.
- Study 1 had about 70 university students draw brand logos and found larger logo drawings near ovulation, a result the authors interpret as greater preference for conspicuous display.
- Study 2, with roughly 1,486 respondents, found increased self-reported intent to buy luxury goods intended for public display but no rise in desire for private-use luxury at fertile phases.
- Study 3, with about 966 participants, showed ovulating women more often picked a luxury gift certificate, and that this preference fell when participants read research claiming men do not notice designer clothes.
- Authors frame the pattern as a socially strategic, mating-linked shift rather than a blanket rise in spending and caution the research is correlational, limited by sample composition and self-report measures.
