Researchers used machine learning to discover that sperm with a wide head relative to length are more likely to clump together and swim collectively, a rare behavior that sometimes helps them reach an egg faster. The study provides a new...
A newly published study found that women who contract COVID-19 during pregnancy are at significantly higher risk of developing pre-eclampsia, the leading cause of maternal and infant death worldwide.
A common antibiotic has been found to reduce low birth weight and premature births, if taken during pregnancy, in countries where malaria is endemic, according to a research review.
There may be a link between exposure to light during pregnancy and fetal brain development. New findings may provide better understanding of certain neurological diseases later in life.
Infants coming from homes with domestic violence often go on to have worse academic outcomes in school due to neurodevelopmental lags and a higher risk for a variety of health issues, including gastrointestinal distress, trouble eating...
Nearly half of New York City mothers who had been trying to become pregnant again before the coronavirus pandemic began stopped in the first few months of the outbreak, a new study shows.
Scientists have discovered an important cause of stroke occurring in the womb or just after birth, paving the way for new treatments. The research identified that a low number of platelets (small blood cells known for enabling clotting)...
About 300,000 to 400,000 fetuses per year from mothers with diabetes develop neural tube defects -- when the tissue that eventually forms the brain and spinal cord fails to form properly -- which can lead to miscarriage or profound...
A new study indicates that an enzyme called protein phosphatase 2 (PP2A) appears to be a major driver of preeclampsia, a dangerous pregnancy complication characterized by the development of high blood pressure and excess protein in the...
If the cerebral hemispheres of the forebrain fail to divide properly in an unborn child, this results in holoprosencephaly. A team has discovered candidate genes that can positively influence the severity of this congenital malformation...
Researchers found that breastfeeding mothers who received either the Pfizer-BioNTech or Moderna vaccination reported the same local or systemic symptoms as what has been previously reported in non-breastfeeding women, with no serious...
For species that rely on sexual reproduction, including mice and men, offspring can only happen if sperm from the male fertilize eggs from the female. Even artificial fertilization techniques depend on donors for both of these cells....
Individuals who are hospitalized during pregnancy due to sepsis have higher odds of complications surrounding childbirth, according to a new study. The study found that pregnancies complicated by sepsis were associated with an increased...
An analysis of more than 20,000 individual medical records suggests that a form of heart valve disease thought to be relatively benign during pregnancy may put women at risk for serious bleeding, high blood pressure, organ damage and...
Half of pregnant women who had a simple blood test to check their iron stores had low iron levels, and one in four had severe iron deficiency, according to a new article. But despite how common iron deficiency is, 40% of pregnant women...
Roe deer are among the few mammals whose embryos go into a particularly long period of dormancy. Using modern molecular methods, researchers have shown for the first time what exactly happens in the embryo during this phase. They have...
A new study analyzes the association between more than 100 environmental exposures and the 'epigenetic clock' of over 1,000 children in six European countries.
Mothers of children with autism who delayed their subsequent pregnancy by 2.5 to three years reduced the likelihood of their next child also being diagnosed on the spectrum, new research shows.
A new gene that controls the completion of meiosis in spermatogenesis has been discovered. Until now, details of the mechanism that inactivates the expression of genes involved in the meiotic program during spermatogenesis had not been...
The breast milk of lactating mothers vaccinated against COVID-19 contains a significant supply of antibodies that may help protect nursing infants from the illness, according to new research.
Researchers used protein sequence data analysis and genome editing technology to find that sperm protein SPATA33 plays an important role in sperm motility regulation. Their findings will aid in the development of male contraceptives and...
Why do women over 35 have more difficulty getting pregnant? After discovering one of the causes of age-related female infertility, researchers suggest that it will be possible in the future to improve the quality of the eggs of older...
Researchers find a way to better pinpoint the 'golden window' when a womb is ready for pregnancy, in a discovery that could help boost IVF success rates.
Mosquitoes spread viruses that cause potentially deadly diseases such as Zika, dengue fever and yellow fever. New research uses gene editing to render certain male mosquitoes infertile and slow the spread of these diseases.
Researchers detail how a ubiquitous signaling molecule plays a critical role in male fertility, orchestrating key steps that promote sperm motility, survival and fertilization success.
Investigators have found that the absence of autoimmune regulator (Aire) in mice results in fertility problems similar to those affecting men with autoimmune polyendocrine syndrome type I (APS-1). Aire-dependent central tolerance plays a...
Teenagers who use cannabis frequently may be more likely to have children born preterm, when they become parents up to twenty years later, finds a new study. The research repeatedly assessed 665 participants in a general population...
A survey of more than 17,000 pregnant and lactating women who received the COVID-19 vaccine showed that they did not experience symptoms any more severe than their non-pregnant counterparts.
A new preclinical study provides the first direct evidence that loss of a placental hormone during pregnancy alters long-term brain development, causing autism-like behaviors in male offspring.
Individuals who contract COVID-19 while pregnant face a higher risk of having a very preterm birth, as well as any preterm birth, according to a large study.
More than one-third of infant caregivers reported serving at least one non-recommended milk type to their infant in the past month -- most providing them daily -- and the majority of toddler caregivers did not follow expert...
Researchers have developed a new way to detect a potentially life-threatening condition that can occur during pregnancy. The condition, placenta accreta spectrum disorder, occurs when the placenta grows too deeply into the uterine wall...
Researchers are comprehensively surveying the short RNA molecules that regulate genome function during embryonic development. Information gained from human ova and embryos helps to understand problems occurring during pregnancy and...
Interventions to prevent obesity in children typically don't target the first 1,000 days of life - -a critical period in which environmental and nutritional cues can increase the risk for obesity. A new study demonstrates how changing...
Researchers surveyed 1,175 surgeons and surgical trainees from across the U.S. to study their or their partner's pregnancy experiences. They found that 48 percent of surveyed female surgeons experienced major pregnancy complications,...
