Scientists find three biological benefits to group swimming of sperm when navigating the female reproductive tract that may also inform studies on infertility.
A novel technique to measure the age of male sperm has the potential to predict the success and time it takes to become pregnant, according to a newly published study by researchers at the Wayne State University School of Medicine.
A new study reveals how sperm change their swimming patterns to navigate to the egg, shifting from a symmetrical motion that moves the sperm in a straight path to an asymmetrical one that promotes more circular swimming.
Male infertility is on the rise, with significant declines in sperm quantity and quality occurring across the human population worldwide in the past two decades. The reason for this is poorly understood, but scientists suspect spermatogenesis – the process by which sperm develops – is a crucial piece in this puzzle.
UC San Diego researchers have described a new method for observing and counting mutations in sperm, and how to use this data to predict the likely impact of these mutations on future children.
Toxicological Sciences continues to feature leading toxicology research in the areas of developmental and reproductive toxicology; endocrine toxicology; neurotoxicology; molecular, biochemical, and systems toxicology; and more.
A test developed by Berkeley Lab scientists can quickly and easily detect whether sperm cells are carrying chromosomal defects, an advance that will help men who have undergone cancer treatment father healthy children.
New research in mice suggests that a high-fat diet early in life may impair male fertility in adulthood. The first-of-its-kind study is published ahead of print in the American Journal of Physiology-Endocrinology and Metabolism.
A breakthrough in fertility science by researchers from Bristol and Mexico has shattered the universally accepted view of how sperm ‘swim’.
Scientists have created a mathematical model that can help explain why so many pregnancies and in vitro fertilization attempts fail. The Rutgers-led study, which may help to improve fertility, is published in the journal Proceedings of the National Academy of Sciences.
An unexpected discovery about fertilization reveals new insights on how sperm and egg fuse and could have major implications for couples battling infertility – and may lead to a future male contraceptive.
