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…
Scientists from the Yale School of Medicine, with research collaborators at the MIND Institute, have found that abnormal placental folds and abnormal cell growths called…
While working with mice, researchers discovered key molecules that switch on stress pathways in preterm lung disorders and potential new drug targets to treat or…
HMS researchers at Beth Israel Deaconess Medical Center examined the current literature on the safety and efficacy of selective serotonin reuptake inhibitor (SSRI) use in…
Japanese scientists have been able to coax mouse stem cells into becoming viable eggs that were able to produce healthy offspring. This will provide a…
