Oocyte quality is the key limiting factor of female fertility. However, compared with other species, the research and understanding of human oocyte quality and human reproductive health is limited.

Reliable assessments of oocyte developmental potential are lacking, making it difficult to select the best quality embryos for transfer after in vitrofertilization. Here, the authors show that a ...

Dec. 10, 2020 — More than 7% of human oocytes contain at least one exchangeless chromosome pair, demonstrating a remarkably high level of meiotic recombination failure, finds a new study.

To further validate the previous results, the team collected human GV oocytes and microinjected the oocytes with DLGAP5 siRNAs. The oocytes microinjected with si‐DLGAP5 exhibited significantly ...

Aging human bodies and aging human oocytes run on different clocks Date: December 9, 2011 Source: American Society for Cell Biology Summary: Reproductive and somatic aging use different molecular ...

Exactly how oocytes accomplish this has been something of a mystery to cellular biologists. Researchers at the Centre for Genomic Regulation in Spain may have solved that mystery.

Rare stem cell population could enable new approaches to fertility treatment. Scientists have isolated and purified rare, human germline stem cells that can be propagated over long periods of time ...

Based in Japan, biotech startup Dioseve’s ambitious goal is to grow human oocytes, or eggs, from other tissue. Its aim is to help people struggling with infertility, and it recently raised $3 ...

Indeed, the human oocyte is very sensitive to radiation — a dose of less than 2 Gy is estimated to be sufficient to destroy 50% of primordial follicles. 14,15. Ultimately, ...
