Reproductive Sciences experts at Cincinnati Children’s discover that the gene Cdc42 is required to support proper alignment and function of Sertoli cells. Scientists at Cincinnati…
Egg and sperm cell size evolved from competition. Limited resources drove gametes to differ vastly in size and number. In most living animals, egg cells…
Scientists no longer have to worry about their bottles of mouse sperm breaking in transit. Researchers in Japan have developed a way to freeze dry…
University of Toledo research shows the centriole’s role in sperm evolved from a shock absorber to a transmission system. Scientists at The University of Toledo…
Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job — to fertilize eggs?…
An alternative explanation of recent findings of declining sperm counts: normal, non-pathological variation. A new study from the Harvard GenderSci Lab in the journal Human Fertility,…
Competition among sperm cells is fierce – they all want to reach the egg cell first to fertilize it. A research team from Berlin now…
A new test quickly and easily identifies when sperm are carrying chromosomal mutations, and could be applied for men hoping to have children. Chemotherapy and…
How does Covid-19 affect sperm and thus the next generation’s immune system? Researchers from the University of Bergen are collecting sperm to find the answer….
Project using roundworms uncovers a mechanism that leads to male infertility caused by high temperatures. University of Oregon biologists have used the model organism Caenorhabditis…
In another fascinating snapshot from deep time, an international team of paleontologists has reported the discovery of specimens of a minuscule crustacean that dates back…
Delivering drugs specifically to cancer cells is one approach researchers are taking to minimize treatment side effects. Stem cells, bacteria and other carriers have been…
A new three-dimensional imaging technique has shown the spiraling movements that human sperm accomplishes while swimming. Previously, these movements had only been inferred from two-dimensional…
Researchers at Yale University have discovered how the regulatory gene, p53, oversees quality control in the production of sperm and possibly other cells with damaged…
Using modern ultrasound equipment, researchers at University of North Carolina’s School of Medicine effectively reduced male sperm counts in laboratory rat tests. The idea of…
According to Dr. Damian Dowling of Monash University’s School of Biological Sciences and Professor Leigh Simmons of the University of Western Australia, reproduction may be…
Naked Mole Rats are all teeth and skin. They are fairly ugly by our usual standards and as it turns out, so is their sperm,…
