During the early phase of oogenesis the total population of gametes in the ovary is produced by intense mitosis and thereafter no further additions take place. The commencement of meiosis is initiated ...

Low oxygen conditions while culturing rGOCs (reconstructed granulosa cell-oocyte complexes) increased oocyte diameters in vitro, and viable eggs were successfully produced using this method. Mature ...

Researchers have succeeded in reconstructing the ovarian environment using mouse stem cells. While growing immature egg cells -- known as oocytes -- from stem cells has been possible, the process ...

An ovary is only a few centimeters wide, but its precious cargo is even smaller. Oocytes are a few dozen micrometers in diameter and are individually wrapped in layers of specialized cells that form a ...

One characteristic of oocyte development and physiology that has been a mystery for 60 years is the highly present cytoplasmic lattices within the cytoplasm of mammalian oocytes. These were initially ...

Israeli scientists report (Thursday 15 September) in Human Reproduction[1] that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and ...

Researchers have found that a carefully orchestrated act of X-chromosome 'yoyo' predicts the successful and efficient development of mammalian egg cells. The findings could pave the way for generating ...

Oocyte cryopreservation is a suitable fertility preservation option for women who are not partnered, have ethical objections to cryopreserving embryos or wish to have complete reproductive autonomy.

Stem cells found in the bone marrow and blood of adult mice can restock ovaries with new egg cells, US scientists report in this week's Cell. "This work demonstrates there is an adult stem cell pool ...
