Previous research has shown that being partnered is associated with
lower testosterone (T) in men and women. To address how multiple partners
may be associated with T, we examined 47 men and 48 women who were single,
monoamorously partnered (partnered), polyamorous (having multiple committed
relationships), or in a polyamorous lifestyle but not currently
multipartnered. Men who were partnered had lower T than all other men, and
polyamorous men had higher T than single men. Polyamorous women had higher
T than all other women. Measures of sociosexual orientation (SOI) and
sexual desire differed in women by relationship type, but not in men.
Findings are interpreted in light of 'competitive' and 'bond-maintenance'
relationship orientations and statuses.
