Learn more about the first-ever 3D map of an ovary and how it could reshape our understanding of fertility, menopause, and ...

A team of reproductive biologists at Nanjing Agricultural University has found that spermidine, a polyamine metabolite, helps oocytes clear away damaged mitochondria in mice, thereby improving ...

Communication between oocytes and granulosa cells is essential for oocyte formation, dormancy, reawakening, and maturation. Researchers have demonstrated that a protein complex called the exocyst ...

Ultrasuperovulation is an advanced technique that significantly increases the number of oocytes produced by female mice. However, existing ultrasuperovulation techniques have a low fertilization rate, ...

The idea of maturing oocytes in the ovary to produce offspring has been implemented in various ways. One such method, ovarian transplantation, is a relatively simple procedure for obtaining eggs, ...

A team of researchers with several members affiliated with Kyoto University and one with Tokyo Medical and Dental University has found a way to restore fertility to mice models with granulosa ...

Recently, the research team led by Wei Li and Chao Liu from Guangzhou Medical University Affiliated Women and Children's Medical Center, in collaboration with Fei Gao’s team from the Institute of ...

Female infants are born with several million immature egg cells, or oocytes. Over the course of the reproductive years, a few hundred of them will develop into mature eggs for potential fertilization.

Oocytes are among the longest-lived cells. Scientists have been trying to understand what enables such longevity, because oocytes—like other nondividing, long-lasting cells—have a high risk of ...

Tsukuba, Japan—In many mammals, a limited number of oocytes are responsible for producing the next generation. Oocytes grow within follicles, which consist of an oocyte and the surrounding granulosa ...
