In a groundbreaking study, scientists at the University of Sydney observed a normally live-bearing Australian lizard lay eggs and then weeks later, give birth to a live baby from the same pregnancy. This unusual reproductive trait is known as bimodality, where some individuals lay eggs while others give birth to live young.
A study published in Economics & Human Biology found that pregnant women who commute at least 50 miles to work are at a higher risk of having low-birth-weight babies. The longer the commute, the greater the risk. Long commutes also led to under-use of prenatal care, which could exacerbate birth outcomes.
A study published in The Lancet Diabetes & Endocrinology journal found that metformin can halve the risk of late miscarriage and preterm births for women with polycystic ovary syndrome (PCOS). Women who received metformin during pregnancy also gained less weight, but there was no effect on gestational diabetes or pre-eclampsia.
A recent study by the University of Kentucky has identified a potential cellular mechanism that connects smoking during pregnancy with an increased risk of offspring obesity later in life. The research found that expectant mothers who smoke cigarettes during pregnancy induce distinct changes in chemerin gene expression in their offspring.
A recent study published in The FASEB Journal found that low oxygen levels during fetal development can lead to premature ovarian ageing and reduced egg availability. Researchers exposed pregnant rats to chronic hypoxia, leading to accelerated ageing of the ovaries and fewer eggs available for future reproduction.
A Norwegian University of Science and Technology study found that children exposed to metformin in utero had a higher risk of obesity. The research, which followed 141 children from PCOS mothers for 5-10 years, also showed no link between metformin use and healthier growth conditions.

The study found that the widely used antimalarial sulphadoxine-pyrimethamine (SP) is no longer effective in preventing malaria in areas with high levels of resistance. In areas where more than 37% of parasites carry six mutations, the effectiveness of SP appears to be fully compromised. The researchers are calling for further investiga...
A recent study published in the European Journal of Preventive Cardiology has found that paternal smoking and maternal passive smoking can significantly increase the risk of congenital heart defects in offspring. The analysis of 125 studies involving over 137,000 babies with congenital heart defects revealed a 74% increased risk for me...
Research found that HIV-exposed but uninfected (HEU) adolescents and young adults are at higher risk of obesity and reactive airway disease compared to their non-exposed peers. Lower prenatal maternal CD4 count was associated with increased body mass index (BMI) in HEU adolescents.
A large study published in The New England Journal of Medicine found that treating women with thyroid antibodies and normal thyroid function with Levothyroxine did not improve the chances of live birth. The study showed similar outcomes in both groups, with 56.6% and 58.3% becoming pregnant, respectively.
Research suggests that sperm DNA damage in male partners may cause recurrent pregnancy loss (RPL), with affected men having twice as much DNA damage as healthy counterparts. High levels of reactive oxygen species were also found, which can damage cells like sperm.
A high-fat, high-sugar diet in pregnant mice causes heart problems in their offspring, which are then passed down to subsequent generations. The defects in heart mitochondria are thought to be caused by epigenetic changes in the mother's eggs.
A University of Maryland School of Medicine study has identified seven bacteria associated with increased risk of spontaneous preterm birth, while higher levels of a natural antimicrobial peptide may lower this risk. The findings hold promise for early diagnosis and prevention of premature births, particularly in African American women.
A new research suggests that a single allergic reaction during pregnancy can prompt significant changes in the brains of offspring, leading to more male-like behavior and brain development. Female rats born to mothers exposed to an allergen during pregnancy exhibited higher levels of male-like behavior and brain changes.
A new study found seven bacteria and immune factors in the vagina and cervix that increase or decrease the risk of spontaneous preterm birth, particularly in African-American women. Higher levels of β-defensin-2 lowered the risk of sPTB associated with cervicovaginal microbiota.
Researchers at Johns Hopkins Medicine studied 22 US state and federal prisons, tracking 1,396 pregnant women over 12 months. Most pregnancies resulted in live births with no maternal deaths, a significant improvement compared to general population statistics.
A new study published in the Journal of Public Health found that immigrant women in Norway are more likely to be overweight during pregnancy. The study, which analyzed data from 219,555 deliveries between 2006 and 2014, also found a significant association between country of birth and weight status.
A Norwegian study found that women under 30 have the lowest risk of miscarriage, while those over 45 face a 53% risk. Previous pregnancy complications also increase the risk, with pre-eclampsia not being a factor.
A study by Norwegian University of Science and Technology found that almost half of all pregnancies are unplanned, and women who are unsure about their choice often feel alone. The research highlights the need for more support and training for healthcare workers to help women make informed decisions.
A study found that mild sleep apnea in pregnant women was associated with higher blood sugar levels and an increased risk of childhood obesity. The researchers suggest that addressing sleep apnea may help improve maternal and infant outcomes.
Researchers found that a mother's diet during pregnancy can affect the expression of genes regulating lung health in her offspring. Epigenetic changes may contribute to increased rates of lung disease, such as asthma, in children born to undernourished mothers.
A study by Laura Miller-Graff found that breastfeeding for six weeks can protect infants from the negative effects of prenatal intimate partner violence. This protective effect was observed in low-income women who experienced IPV during pregnancy.
Researchers estimate that alcohol use during pregnancy and drunken driving are linked to substantial harm beyond the drinker, including fetal alcohol syndrome and road traffic fatalities. Effective prevention strategies targeting vulnerable populations, such as pregnant women and road users, are necessary.
Researchers found that Dot had a typical-use failure rate of 5 percent and a perfect-use failure rate of 1 percent, comparable to other fertility awareness-based methods. The study also found no association between pregnancy and sociodemographic characteristics.
A study of nearly 500,000 women found that taking paracetamol or other painkillers during pregnancy increases the risk of asthma in children, but the risk is similar when other types of painkillers are used. The research suggests that another factor linked to painkiller use and asthma risk may be chronic pain and stress.
A study led by the University of Colorado found that choline supplements can prevent fetal brain developmental problems when a mother has the flu during pregnancy. Higher levels of choline in mothers also improved their children's ability to pay attention and regulate their behavior.
Researchers developed a rapid, non-invasive urine test to diagnose preeclampsia, with an accuracy rate of 86% compared to other biochemical tests. The 'Congo Red Dot' test can provide results within three minutes, allowing for early detection and treatment, thereby reducing maternal deaths and premature births.
A CU Anschutz study discovered a genetic component that breaks down contraceptive hormones in some women, potentially leading to pregnancy. The research may lead to the development of more precise medical tools to tailor treatment to individual patients.
Researchers use photoacoustic imaging to detect placental ischemia in pregnant rats, revealing early signs of preeclampsia. The non-invasive procedure poses little risk to the fetus and may lead to better treatment outcomes.
A randomized clinical trial found no association between high-dose vitamin D supplementation during pregnancy and the risk of asthma in children at age 6. The study followed 545 children whose mothers received either high-dose or standard-dose vitamin D supplementation.
