Competition between sperm is fierce – they all want to be the first to reach the egg to fertilize it. A research team from Berlin has shown in mice that the ability of sperm to move forward depends ...
Research Shows that Taking Antidepressants Does Not Have a Negative Impact on the Success of IVF in Men
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 ...
The Secret Voltage Switch of Sperm: The Mystery of Motility
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...
Why Heat Stress Damages Sperm
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...
Human Uterus Colonized by Clones With Cancer-Causing Mutations that Occur Early in Life
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 Identify Dual Origin of Cells that Control Puberty and Reproduction
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...
Early Detection of Endometriosis: Research Into New Diagnostic Methods
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...
Scientists Discover New Epigenetic Switch
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 ...
