The effectiveness of three females treated with oestradiol and three females treated with testosterone to detect oestrus was examined in 304 dairy cows maintained indoors year-round. Three heifers were treated weekly with 10 mg oestradiol benzoate per 250 kg of body weight. One cow and two heifer...

We found that dominant males had significantly higher circulating testosterone levels than subordinates during the early and late breeding seasons. No changes in solo song characteristics were found between both time points. Further, experimental implantation of captive adult females with exogenous ...
Vaccine-induced antibody responses were increased in females by estradiol and decreased in males by testosterone. The benefit of elevated estradiol on antibody responses and protection against influenza in females is diminished with age in both mice and humans....

The steroid hormones testosterone and its metabolite estradiol, for instance, have both been implicated in mammalian parental behavior (Wynne-Edwards and Reburn, 2000). Estradiol acts in concert with the neuropeptide oxytocin, which strongly facilitates lactation and mother–infant bonding after ...
It has been argued that during fertile cycle phases, paired women may engage in short-term extra-pair relationships to mate with partners of high genetic quality (such as high testosterone levels, masculinity, dominance, symmetry) (e.g., Gangestad and Thornhill 2008). Two recent meta-analyses...
