AN increases rates of fertility problems, but how or when AN negatively influences future fertility is unclear. We sought to determine whether biomarkers of ovarian reserve were impacted in AYA with AN. Cross-sectional study. Tertiary care center. Females with AN and amenorrhea (n=97) at the pre-intervention visit of a clinical trial, n=19 females without an eating disorder or menstrual dysfunction. Serum anti-Müllerian hormone (AMH) concentrations. AMH levels were higher in AYA with AN than unaffected adolescents (4.7 vs. 3.2ng/mL; P=.03). Neither FSH nor inhibin B differed between groups. In 19.6% of participants with AN, AMH levels were elevated above the normal range (>6.78ng/mL). These subjects had a longer disease duration than those with normal AMH levels (9 vs. 3mos; P=.03); age or degree of malnutrition did not differ between AN subjects wi explored.One of the main challenges to understand drug addiction is defining the biological mechanisms that underlie individual differences in recidivism. Studies of these mechanisms have mainly focused on the brain, yet we demonstrate here a significant influence of the peripheral immune system on this phenomenon. Lewis (LEW) and Fischer 344 (F344) rats have different immunological profiles and they display a distinct vulnerability to the reinforcing effects of cocaine, with F344 more resistant to reinstate cocaine-seeking behavior. Bone marrow from male LEW and F344 rats was transferred to male F344 rats (F344/LEW-BM and F344/F344-BM, respectively), and these rats were trained to self-administer cocaine over 21 days. Following extinction, these animals received a sub-threshold primer dose of cocaine to evaluate reinstatement. F344/LEW-BM but not F344/F344-BM rats reinstated cocaine-seeking behavior, in conjunction with c
