Abstract

Daily urine samples were collected from 5 female golden lion tamarins (Leontopithecus rosalia) over a period of 3 or more months, and urinary oestrogen concentrations were determined by radioimmunoassay. Four females exhibited regular patterns of oestrogen excretion, with a peak-to-peak periodicity of 19.6 ± 1.4 days. Levels of oestrogen excretion tended to vary between, but not within, individual females. Post-partum oestrogen patterns included periods of clear oestrogen cyclicity before conception, with dramatic elevations in oestrogen excretion following conception. Oestrone was the predominant urinary oestrogen excreted by female lion tamarins. Enzyme hydrolysis with Helix pomatia β-glucuronidase/sulphatase was an efficient method of liberating conjugated oestrogens in tamarin urine. Urinary oestrogen determinations can provide useful information about reproductive status in female lion tamarins.
