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
Researchers uncover genetic mystery of infertility
Researchers have discovered a novel parasitic gene in fruit flies that is responsible for destroying the eggs in the ovaries of their daughters. Just like fruit flies, human genomes are filled with mobile parasitic genes called transposons and, similar to … Continue reading
Sperm DNA damage may contribute to repeated miscarriages, study reports
Some cases of recurrent pregnancy loss may be caused by sperm DNA damage in the male partner, rather than by a problem in affected women, according to research presented at ENDO 2019, the Endocrine Society’s annual meeting in New Orleans … Continue reading
A breakthrough in male infertility?
Scientists at Newcastle University in the UK report that they have solved the importance of a gene in regulating the production of fully functioning sperm. For the first time, they say, they have identified the role of a gene, RBMXL2, … Continue reading
New technique may fix genetic cause of infertility
Scientists have created healthy offspring from genetically infertile male mice, offering a potential new approach to tackling a common genetic cause of human infertility. Our sex is determined by the X and Y chromosomes. Usually, girls have two X chromosomes (XX) and … Continue reading
Scientists modify genes of embryos
A team of researchers in Portland, Oregon has carried out the first known attempt at genetically modifying human embryos in the United States. According to an article in the MIT Technology Review, researchers at the Oregon Health and Science University successfully … Continue reading
Cracking the genetic code for infertility
A landmark study, published in The New England Journal of Medicine and Human and Molecular Genetics, shows for the first time that a mutation in a particular gene is the major cause of two human fertility disorders: premature ovarian failure … Continue reading
