During fertilization, the egg and the sperm are supposed to contribute precisely one copy of
each chromosome to the embryo. However, human eggs frequently contain an incorrect …

The aim of this International Menopause Society White Paper on premature ovarian
insufficiency (POI) is to provide the latest information regarding this distressing condition …

Molecular mechanisms of ovarian aging and female age-related fertility decline remain
unclear. We surveyed the single-cell transcriptomic landscape of ovaries from young and …

Transgenerational effects of maternal nutrition or other environmental 'exposures' are well
recognised, but the possibility of exposure in the male influencing development and health …

BACKGROUND There is a great inter-individual variability of ovarian ageing, and almost
20% of patients consulting for infertility show signs of premature ovarian ageing. This …

Mammalian eggs (oocytes) are formed during fetal life and establish associations with
somatic cells to form primordial follicles that create a store of germ cells (the primordial pool) …

Bidirectional somatic cell–oocyte signaling is essential to create a changing intrafollicular
microenvironment that controls primordial follicle growth into a cohort of growing follicles …

Germline stem cells that produce oocytes in vitro and fertilization-competent eggs in vivo
have been identified in and isolated from adult mouse ovaries. Here we describe and …

Reproduction is required for the survival of all mammalian species, and thousands of
essential'sex'genes are conserved through evolution. Basic research helps to define these …

Ovarian aging in women correlates with the progressive loss of both the number and quality
of oocytes. When these processes occur early or are accelerated, their clinical correlates are …
