In vitro fertilization (IVF) is a time-consuming and often stressful procedure, but it is increasingly being used to help couples realize their dream of having a child. But how does stress affect the ...
Researchers at Stockholm University have uncovered the hidden intricacies of how sperm develop from passive spectators into dynamic swimmers. This transformation is a crucial step on the path to ferti...
Using the model organism Caenorhabditis elegans, biologists have identified molecular mechanisms that cause DNA damage in sperm and contribute to male infertility after exposure to heat. In humans, th...
Many cells in the inner lining of the uterus carry “cancer-causing” mutations that often occur early in life, according to scientists at the Wellcome Sanger Institute, the University of Cambridge,...
Researchers at the Francis Crick Institute have demonstrated that gonadotrophs, cells in the pituitary gland that play an important role in puberty and reproduction, originate from two different popul...
Endometriosis is a common, debilitating chronic disease that affects more than 190 million women worldwide. Early diagnosis remains a major clinical and health policy challenge. The average time to di...
Researchers have discovered that a DNA modification called 5-formylcytosine (5fC) acts as an activating epigenetic switch that triggers genes in early embryonic development. This discovery shows that ...
