The Effect of Resistive Exercise Rest Interval on Hormonal Response, Strength, and Hypertrophy With Training
The results show that in healthy, recently untrained males, strength training with 1 minute of rest between sets elicits a greater hormonal response than 2.5-minute rest intervals in the first week of training, but these differences diminish by week 5 and disappear by week 10 of training.
Manipulation of the oxytocin system alters social behavior and attraction in pair-bonding primates, Callithrix penicillata
Interactions among Paternal Behavior, Steroid Hormones, and Parental Experience in Male Marmosets (Callithrix kuhlii)
A relationship in C. kuhlii between paternal behavior, hormones, and paternal experience is suggested and rates of infant-carrying appear to be linked to hormone levels, and hormone levels in turn are affected by experience caring for young.

Social and reproductive conditions modulate urinary cortisol excretion in black tufted‐ear marmosets (Callithrix kuhli)
Data reveal that activity in the HPA axis in marmosets is sensitive to psychosocial stressors, and that urinary cortisol can provide a useful quantitative measure of HPA reactivity, and as in other callitrichids, delayed breeding in daughters and reproductive anomalies in C. kuhli appear to be mediated by mechanisms other than elevated HPA activity.

Variation in steroid hormones associated with infant care behaviour and experience in male marmosets (Callithrix kuhlii)
We describe temporal patterns of change in paternal behaviour and urinary concentrations of the steroid hormones testosterone (T) and oestradiol (E(2)) in male black tufted-ear marmosets, Callithrix…
Rank-related maternal effects of androgens on behaviour in wild spotted hyaenas
It is shown that androgen concentrations in wild female spotted hyaenas (Crocuta crocuta) are higher during late gestation in dominant females than in subordinate females, and rank-related maternal effects of prenatal androgen exposure can adaptively influence offspring phenotype in mammals.
