Abstract EN
Previous work showed that retaining residual ovarian tissue protects young mice from accelerated bone loss following ovarian failure.
The present study was designed to determine whether this protection is also present in aged animals.
Aged (9–12 months) C57BL/6Hsd female mice were divided into: CON (vehicle), VCD (160 mg/kg; 15d), or OVX (ovariectomized).
Lumbar BMD was monitored by DXA and μCT used to assess vertebral microarchitecture.
BMD was not different between VCD and CON at any time point but was lower (P<.05) than baseline, starting 1 month after ovarian failure in VCD and OVX mice.
Following μCT analysis there were no differences between CON and VCD, but OVX mice had lower bone volume fraction, trabecular thickness, and a trend for decreased connectivity density.
These findings provide evidence that retention of residual ovarian tissue may protect aged follicle-depleted mice from accelerated bone loss to a lesser extent than that observed in young mice.
