Researchers identify protein essential for male fertility
Fertilization is the union of two cells: an egg and a sperm. Before the egg and the sperm fuse, an event known as the “acrosome reaction” needs to occur in the sperm. Now, a team from Osaka University in Japan … Continue reading
Scientists discover new protein that could improve fertility treatments
A new protein, named MAIA after the Greek goddess of motherhood, could be crucial in helping doctors better understand some aspects of infertility and develop novel treatments. Currently, infertility is unexplained in more than half of people who are unable … Continue reading
Human eggs remain healthy for decades by putting ‘batteries on standby mode’
Immature human egg cells skip a fundamental metabolic reaction thought to be essential for generating energy, according to the findings of a study by researchers at the Centre for Genomic Regulation (CRG) published in the journal Nature. By altering their metabolic … Continue reading
Study finds frozen eggs more efficient option than IVF
The largest U.S. report of elective fertility preservation outcomes to date found that 70 percent of women who froze eggs when they were younger than 38 — and thawed at least 20 eggs at a later date — had a … Continue reading
Study: Sperm switch swimming patterns to locate egg
A new study from Cornell University reveals how sperm change their swimming patterns to navigate to the egg, shifting from a symmetrical motion that moves the sperm in a straight path to an asymmetrical one that promotes more circular swimming. … Continue reading
Sperm help ‘persuade’ female to accept pregnancy
Sperm are generally viewed as having just one action in reproduction – to fertilize the female’s egg – but studies at the University of Adelaide in Australia are overturning that view. Published in Communications Biology, new research shows that sperm … Continue reading
Women’s egg quality dependent on metabolic factors
Increasing the levels of a chemical found in all human cells could boost a woman’s fertility and help select the best eggs for IVF, according to University of Queensland, Australia, research. In an in-depth study of the final steps of … Continue reading
Studies look into how DNA crossovers can drive healthy or abnormal sperm, egg cell division
In the famous words of movie character Forrest Gump, “Life is like a box of chocolates; you never know what you’re gonna get.” The same principle applies to human genetics. When the body forms sperm or egg cells in a … Continue reading
New discovery shows how men may contribute to infertility
A new study at the University of Toledo shows that a father donates not one, but two centrioles through the sperm during fertilization, and the newly discovered sperm structure may contribute to infertility, miscarriages and birth defects. The centriole is … Continue reading
New research extends egg health
Women have been told for years that if they don’t have children before their mid-30s, they may not be able to. But a new study from Princeton University has identified a drug that extends egg viability in worms, even when … Continue reading
