A roadmap for the genetic analysis of renal aging

Several studies show evidence for the genetic basis of renal disease, which renders some individuals more prone than others to accelerated renal aging. Studying the genetics of renal aging can help us to identify genes involved in this process and to unravel the underlying pathways. First, this opinion article will give an overview of the phenotypes that can be observed in age-related kidney di...

An Update on Ovarian Aging and Ovarian Reserve Tests

Ovaries are the female organs that age more quickly than other tissues such as the uterus, the pituitary gland or pancreas. Different from males, an interesting question is why and how the females lose fertility so rapidly. During the aging process, both the number and quality of the oocytes in the ovaries decrease and reach to a point beyond that no more viable offspring may be produced and th...

//Ovarian Aging

With age, there is a decline in both the quantity and quality of the pool of follicles and oocytes. Linear extrapolation of follicular depletion in women with regular menses predicts that, by 50 years of age, each ovary would contain 2500 to 4000 primordial follicles. Because the menopausal ovary is largely devoid of follicles, follicular depletion apparently accelerates in the last decade of r...

Ovarian aging and premature ovarian failure.

Physiological reproductive aging occurs as a result of a decrease in the number and quality of oocytes in ovarian cortex follicles. Although the reason for the decrease in the quality of the pool and follicular oocytes is not fully understood, endocrine, paracrine, genetic, and metabolic factors are thought to be effective. Nowadays, in order to understand the mechanisms of ovarian aging, genom...
