The genetic causes of female infertility
Many women are unable to conceive and deliver a healthy baby due to genetic factors. Sometimes this is due to an inherited chromosome abnormality. Other times it is because of a single-gene defect passed from parent to child. Genetic disorders and … Continue reading
Research offers insights into the reproductive process
The behavior of sperm cells is due, in part, to the individual DNA make-up of these cells, rather than only to the genetics of males, a new study has found. These results, which provide a new understanding of the competition … Continue reading
New research examines causes of infertility, miscarriage, birth defects
Researchers at Rutgers University, Memorial Sloan Kettering Cancer Center, Rockefeller University, and Cornell University are teaming up to examine how the processes that regulate gene expression and chromosome behaviors can lead to health issues, including cancer, birth defects, miscarriage and … Continue reading
No swimming? Molecule regulating sperm motility discovered
A team from Osaka University has used protein sequence data analysis and genome editing technology to find a gene, SPATA33, that plays an important role in sperm motility regulation. Targeting the mechanism by which SPATA33 controls sperm motility adds a … Continue reading
Genes linked to longer reproductive lifespan in women
The age at which women go through menopause is critical for fertility and impacts healthy aging in women, but reproductive aging has been difficult for scientists to study and insights into the underlying biology are limited. Now, scientists have identified … Continue reading
Genetic mutations may be linked to infertility, early menopause
A new study from Washington University School of Medicine in St. Louis identifies a specific gene’s previously unknown role in fertility. When the gene is missing in fruit flies, roundworms, zebrafish and mice, the animals are infertile or lose their … Continue reading
Study finds increased fertility for women with Neanderthal gene
File this one under “who knew?” According to a study published in Molecular Biology and Evolution by researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden, one in three women in Europe inherited the receptor … Continue reading
Researchers discover genes involved in infertility
Most cells in the tissues of most organisms proliferate through somatic cell division (mitosis). This is a continuous cycle where a single cell doubles its genetic information (chromosomes) and divides equally to create two copies of the original cell. In … Continue reading
Scientists discover ‘roadmap’ for ovarian aging
Infertility likely stems from age-related decline of the ovaries, but the molecular mechanisms that lead to this decline have been unclear. Now, scientists have discovered, in unprecedented detail, how ovaries age in non-human primates. The findings, published in Cell, reveal … Continue reading
New gene for male infertility discovered
At least one in five cases of infertility remains unexplained. Male factors contribute to about half of these cases and, much of the time, men lack a specific causal diagnosis for their infertility. Researchers estimate that genetics could explain up … Continue reading
