Presence of anti‐müllerian hormone in the squirrel monkey (Saimiri boliviensis): gender and seasonal differences

Abstract

Anti-mullerian hormone levels in female squirrel monkeys are the highest in any primate species reported, whereas in the male, levels are within reported ranges. The AMH assay may allow us soon to assess the squirrel monkey fertility potential as a function of various factors.

Quantifying the intraindividual variation of antimüllerian hormone in the ovarian cycle

“…Intriguing data now link clock genes (which control biological 24-hour cycle rhythms) and AMH genes in other species (49). Seasonal change in AMH has also been described in stallions (50) and squirrel monkeys (51). Although in humans the quantitative changes in AMH from any single factor may be minimal, it appears clear that biological variation can include a variety of influences and that the sum of these effects can result in significant changes for an individual.…”

Preliminary investigation into long‐term stress by isolated captivity‐related changes of reproduction hormones in Cynomolgus monkey

“…16,[21][22][23] Stress evaluation related to the menstrual cycle is particularly optimal in Old World monkeys, such as Cynomolgus monkeys, where the menstrual cycle is approximately 25-35 days, resembling that in women. 22 Unlike other monkeys, such as capuchins, squirrel monkeys, black-capped capuchins, and redtailed monkeys, Cynomolgus monkeys lack seasonal variations in ovarian activity, [24][25][26][27] making them optimal models for assessing stress during the estrous cycle. Furthermore, the Cynomolgus monkey is one of the most commonly used species in biomedical research, with a high global demand.…”
