US Scientists Aim to Make Sperm from Stem Cells
US researchers say they will redouble their efforts to create human sperm from stem cells following the success of a Japanese study involving mice. A Kyoto University team used mice stem cells to create eggs, which were fertilised to produce baby mice.
Dr Renee Pera, of Stanford University in California, aims to create human sperm to use for reproduction within two years, and eggs within five years. Read full article.
Researchers Re-Create Eggs to Treat Infertility
Researchers working with laboratory rats have developed a technique that could someday help infertile women who lack usable eggs because of a hormone imbalance to conceive with new eggs created from their own ovaries.
Many women are unable to conceive because of a condition known as polycystic ovary syndrome, in which the ovaries fail to secrete enough hormones to stimulate egg production. Injury to the ovaries caused by radiation or surgery also can interfere with a woman’s ability to produce enough viable eggs, or oocytes, to achieve pregnancy. Read full article.
Nobel Prize For Medicine Awarded to Gurdon, Yamanaka for Stem Cell Discoveries
British scientist John Gurdon and Shinya Yamanaka of Japan shared the 2012 Nobel Prize in physiology or medicine Monday for experiments separated by almost 50 years that provide deep insight into how animals develop and offer hope for a new era of personalized medicine.
“Their findings have revolutionized our understanding of how cells and organisms develop,” the Nobel committee said in the prize announcement. Read full article.
New Discovery to Improve Success Rates of IVF
Researchers from the University of Otago, Christchurch, are collaborating with clinicians at Fertility Associates in Christchurch to develop a test to significantly improve the success rate for in vitro fertilisations implantations.
Christchurch obstetrics and gynaecology researcher, Dr Gloria Evans, has just published a paper in the international journal Fertility and Sterility which shows positive results for a test to determine the optimal time to implant a fertilised embryo through IVF. Read full article.
