Cryos International is located on the fifth floor of a small building in Aarhus, Denmark. It looks like any other office, but inside, it’s among the world’s largest sperm banks.

How the World’s Governments Have Regulated Human Genome Editing
Three members of McGill University’s Centre of Genomics and Policy—Rosario Isasi, Erika Kleiderman, and Centre Director Bartha Maria Knoppers—have published a global survey of restrictions on modifying the human genome. The article, which appears in Science and is free to access, comes in the midst of a simmering debate about CRISPR gene editing, a powerful technique for rewriting living genomes, which has already been used at least once in (nonviable) human embryos and inspired calls for a voluntary moratorium on editing human egg, sperm, and embryonic cells.
Infertility Treatments, in Your Home
Many would-be parents are turning to at-home products to help them conceive—before, during and after seeking professional treatment for infertility. The growing do-it-yourself arsenal ranges from devices that mechanically assist the uniting sperm and egg, to tests that diagnose what’s going wrong. Some are Food and Drug Administration approved; some are MacGyver-esque uses for ordinary household items.
End of The vasectomy? New Implant Allows Men to Turn Their Fertility On and Off With the Flick of a Switch
From vasectomies to the male contraceptive pill, there have been many attempts to shift the burden of birth control burden onto men. Now one German entrepreneur believes he has the solution – a ‘switch’ to stop sperm from reaching the penis. The valve – which is implanted internally is designed to divert the flow of sperm back to the man’s testicles, making him temporarily infertile. If he later decides he wants a wants to become a father, he simply locates the implant in his scrotum and flicks the switch back, allowing sperm to be ejaculated.
9 Things that Can Lower Your Sperm Count and Lead to Infertility
While you may not worry about fertility and your sperm count unless you’re trying to have babies, you would be surprised to know how these nine factors could potentially harm male fertility.
Baby Boy Gets Guinness World Record After Conception from World’s Oldest Sperm
A baby boy was born in June of 2015 after being conceived from the world’s oldest sperm. His dad gave the sperm specimen 23 years ago at the age of 15, after receiving a cancer diagnosis and being advised his treatment could make him infertile. After a successful conception from what became the world’s oldest sperm, his new baby made it into the Guinness Book of World Records.
This is why a Mouse’s sperm is Longer than an Elephant’s
There are competing ideas about why sperm size differs among animals. One idea holds that small animals and large animals have wildly different metabolic constraints. Small animals with high metabolisms are better able to produce new sperm cells than large animals that form new cells more slowly.
Scientists Discover that Sperm Cells Can Slither
Scientists have discovered that sperm have a previously unrecognized skill – they can swim in a “slither” mode when they are close to the wall of their environment.
Teenage Exposure to Pesticides May Lead to Abnormal Sperm, New Study Says
Adolescent exposure to environmental pollutants known as organochlorines may lead to defective sperm, according to a study published today by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University and co-authors. The research is the first to look for associations between exposure to these chemicals in the teenage years and abnormalities in sperm that are associated with fertility problems later in life.
Restoring Testosterone Production in Men Better than Replacing It
Testosterone is important for red blood cells, bone growth, sexual function and mood in men. Men are generally treated for low levels of the hormone, called hypogonadism, with testosterone replacement therapy using topical treatments that often lower sperm counts.
