چکیده

Recently there has been increasing interest in the estimation of age-specific fecundability as a result of the progressive postponement of age at family formation in Western countries. It must be noted, however, that the possible negative effects of the postponement could act not only on the physiological component of the ability to conceive but also on the behavioural component (i.e., sexual activity). The main aim of our study was to verify if, the desire to have a child being equal, the coital frequency decreases in one’s 30s as compared to the 20s. For our analysis we used the data from the Multinational Study in Daily Fecundability (MSDF), which has produced a very rich database with behavioural and physiological information prospectively collected on every cycle. We found empirical evidence that the desire to have a child only partially compensates for the decline of coital frequency with age.

I-8: Somatic Cell Nuclear Reprogramming byMouse Oocytes Endures Beyond ReproductiveDecline

Background: The mammalian oocyte has the unique feature of supporting fertilization and normal development while being able of reprogramming the nuclei of somatic cells towards pluripotency, and occasionally even totipotency. Whilst oocyte quality is known to decay with somatic ageing, it is not a given that different biological functions decay concurrently. In this study, we tested whether ooc...

Does white matter structure or hippocampal volume mediate associations between cortisol and cognitive ageing?

Elevated glucocorticoid (GC) levels putatively damage specific brain regions, which in turn may accelerate cognitive ageing. However, many studies are cross-sectional or have relatively short follow-up periods, making it difficult to relate GCs directly to changes in cognitive ability with increasing age. Moreover, studies combining endocrine, MRI and cognitive variables are scarce, measurement...

On the involvement of prefrontal networks in cognitive ageing.

Normal ageing is associated with a wide variety of disturbances in the structure and function of the human brain. Recent neuroimaging studies suggest that the prefrontal cortex (PFC) is particularly vulnerable to the effects of ageing. These findings are compatible with the so-called 'frontal ageing hypothesis' which has been formulated on the basis of neuropsychological research on non-patholo...
