Butterflies have evolved to produce a strongly scented chemical in their genitals that they leave behind after sex to deter other males from pursuing their…
New research has found as climate change causes the world’s oceans to warm, baby sharks are born smaller, exhausted, undernourished, and into environments that are…
A new study provides the first detailed documentation of a shallow water fish diving 450 feet deep to spawn. Uncovering this very rare spawning behavior…
Adding nuts to a Western-style diet has an effect on its epigenetics; this research shows, for the first time, that there are regions in the…
University of Oregon and Northwestern University biologists show that too many crossover events can increase infertility. The exchange of DNA between chromosomes during the early…
University of Massachusetts Amherst scientists say discovery could lead to better diagnosis of male infertility. Researchers at the University of Massachusetts Amherst have identified a…
Small bivalved crustacean ostracods are the most abundant fossil arthropods since the Ordovician and play an important role in paleoenvironmental reconstruction and evolutionary biology. The…
For the first time, scientists have created pigs, goats and cattle that can serve as viable “surrogate sires,” male animals that produce sperm carrying only…
School spaces with newer furniture show significantly lower levels of hazardous exposures. There are good reasons to be worried about indoor air quality right now,…
How Human Sperm Really Swim: New Research Challenges Old Assumption New research in fertility science by researchers from Bristol and Mexico has shattered the universally…
Human Eggs Prefer Some Men’s Sperm Over Others Human eggs use chemical signals to attract sperm. New research from Stockholm University and Manchester University…
New hormone that stimulates sexual functions in fish could lead to novel infertility treatments in humans. When University of Ottawa biologists Kim Mitchell and Vance…
Children of mothers prescribed macrolide antibiotics during the first trimester of pregnancy are at an increased risk of major birth defects when compared with penicillin,…
Non-invasive prenatal tests (NIPTs) are used for fetal genetic disease screening in pregnant women. In contrast, invasive tests like amniocentesis carry the risk of causing…
Sperm are influenced by diet, and the effects arise rapidly. This is the conclusion of a study by researchers at Linköping University, in which healthy…
By introducing a chemical cocktail to granulosa cells, researchers in China induced the cells to transform into functional oocytes in mice. Once fertilized, these oocytes…
Researchers from the Yale School of Medicine have identified the molecular pathways involved in the aging of human eggs; which could eventually lead to treatments…
New research from Yale University reveals the first evidence that childbearing may cause accelerated aging in women. The researchers tested 100 healthy postmenopausal women from…
