Turning X chromosome ‘off and on again’ critical for oocyte development
Researchers at the Centre for Genomic Regulation (CRG) in Barcelona have identified a potential new diagnostic marker that predicts the successful and efficient development of mammalian egg cells. The findings could pave the way for generating artificial oocytes in the … Continue reading
How aging impairs women’s fertility
Age may adversely affect women’s fertility by impairing levels of RNA molecules, which in turn alter the function of genes involved in key biological pathways during the final maturation stage of a human egg cell, according to the findings of … Continue reading
New technique could provide ‘egg health’ indicators
Using the power of single-cell analysis, researchers at the Babraham Institute in the U.K. have assessed the effects of age on egg cells (oocytes) in mice, particularly looking to identify genomic and epigenetic factors that relate to reduced developmental competence. … Continue reading
How an egg cell’s ‘operating manual’ sets the stage for fertility
Recently published work from Carnegie Institution for Science has revealed the genetic instructions immature egg cells go through step by step as they mature into functionality. The findings improve our understanding of how ovaries maintain a female’s fertility. The general … Continue reading
Researchers find key to preserving fertility during chemotherapy
One of the most significant impairments of the quality of life after a chemotherapy is infertility. Researchers have now identified the mechanism of chemotherapy-induced infertility in females. While men produce new sperm cells throughout their life, women are born with … Continue reading
Zinc deficiency may harm egg development, study finds
Ovulation disorders are a leading cause of female infertility. Researchers at Pennsylvania State University have found that zinc deficiency can negatively affect the early stages of egg development, reducing the ability of the egg cells to divide and be fertilized. … Continue reading
