The researchers also discovered associations between preconception phthalate exposure and changes in women's reproductive hormones, inflammation, and oxidative stress.
Researchers at Texas A&M University found that it takes over a month for negative alcohol effects to wear off, and fathers' sperm are still negatively impacted by drinking even during the withdrawal process. The study suggests that men should abstain from alcohol at least three months prior to conceiving.

A recent study published in JAMA Network Open analyzed data from 10,000 US adolescents and found a significant increase in e-cigarette use during late pregnancy. However, the study revealed no statistically significant association between e-cigarette use and an increased risk of small-for-gestational-age birth among adolescents.
A Cambridge-led study discovered the cause of pregnancy sickness, attributing it to a hormone produced by the fetus called GDF15. The severity of nausea and vomiting depends on the amount of GDF15 produced and the mother's sensitivity to it. Building up tolerance to GDF15 before pregnancy may prevent sickness.
A new study finds that a hormone produced by the fetus and a mother's sensitivity to it are the causes behind nausea and vomiting during pregnancy. Lowering GDF15 levels or pre-exposing women to the hormone may mitigate symptoms, providing potential ways to prevent extreme forms of pregnancy sickness.
A multicenter observational cohort study found that cannabis exposure was associated with a higher risk of small-for-gestational-age birth, medically indicated preterm birth, stillbirth, and hypertensive disorders of pregnancy. The risk was particularly pronounced among those who continued to use cannabis beyond the first trimester.
Using metformin plus insulin to treat preexisting type 2 or gestational diabetes diagnosed early in pregnancy did not show a reduction in composite neonatal adverse outcomes. The study suggests that the effect of reducing large-for-gestational-age infant risk after adding metformin to insulin warrants further investigation.
A new study found no increased risk of major congenital malformations in infants exposed to second-line non-insulin antidiabetic medications during pregnancy compared to those treated with insulin. The study examined over 3.5 million pregnancies and provided reassurance on the safety of these medications for fetuses.
Embryos with morphologically non-good-quality blastocytes and those from women aged ≥ 35 years showed lower rates of implantation, clinical pregnancy, ongoing pregnancy, and live births after blastocyst shrinkage. Post-warming blastocyst shrinkage adversely affects ART outcomes.
New research reveals that early life gene epimutations in the BRCA1 gene may increase the risk of triple-negative breast cancer (TNBC). The study found that these epimutations occurred twice as often in girls than boys and were associated with a higher risk of TNBC, particularly in women who experienced pregnancy-related changes.
Women who have had a C-section may face difficulties conceiving due to reduced fertility and increased risk of labor complications. The study found that women with fertility problems also had more C-sections.

This policy, formerly known as the Mexico City Policy, had detrimental effects on family planning service delivery and utilization.
A study published in PLOS Medicine found that 90% of pregnant women in high-income countries lack key vitamins necessary for healthy pregnancies and fetal development. The situation is expected to worsen as more people adopt plant-based diets, leading to increased risk of nutrient deficiencies.
A new study from the University of Wisconsin-Madison found that individuals born in dry counties due to Prohibition-era laws lived longer, with an average additional lifespan of approximately 1.7 years. This increase in longevity is equivalent to nearly 15% of the overall life expectancy improvements for those born between 1900-1930.
Women who underwent bariatric surgery had lower pregnancy weight gain compared to controls with similar early pregnancy characteristics. The study found no difference in weight gain based on surgical procedure or surgery-to-conception interval, but suggested a potential benefit for women with shorter intervals.
A recent study found that nearly all pregnant women have low levels of essential vitamins and minerals, with some developing deficiencies in late pregnancy. Supplementing with over-the-counter multivitamins significantly reduced nutrient deficiencies before and during pregnancy.

The Global Centre for Asian Women’s Health found that a Mediterranean diet rich in fruits, nuts, whole grains, and healthy fats can reduce the risk of gestational hypertension and preterm birth. The study also linked narrowing of retinal arterioles before conception to reduced fetal growth during pregnancy.
During pregnancy, distinct pools of stem cells in the adult brain are activated, giving rise to specific types of olfactory bulb neurons that enable mothers to recognize their own pups. These new neurons are temporarily formed and disappear after birth, highlighting the brain's ability to adapt to specific needs.
A Canadian study found that infants exposed to biologic agents during pregnancy have normal immune development and can safely receive the rotavirus vaccine. The study, involving 191 infants across six sites in Canada, aimed to change vaccination guidelines to protect more babies from severe illness.

Research found that women experiencing high levels of anxiety, depression, or stress during pregnancy had children with increased symptoms of attention deficit hyperactivity disorder (ADHD) and aggressive behavior. The study suggests providing mental health care and support during pregnancy can help prevent childhood behavior problems.
A meta-analysis of 57 studies found that prenatal cannabis exposure is associated with an increased risk of preterm delivery, low birth weight, and neonatal intensive care unit (NICU) admission. However, it does not appear to increase the risk of birth defects or death within one year.
Two systematic reviews and meta-analyses found that delaying umbilical cord clamping by at least two minutes can reduce the risk of death in premature babies. The studies included over 10,000 babies from 60 studies and showed a significant reduction in mortality rates for deferred clamping compared to immediate clamping.
Two COVID-19 studies on Singapore mothers and children found vaccination during pregnancy reduces newborn infection risk by up to 44.4%. Vaccination also showed potential protection against Long COVID in children under 18, with males more likely to experience symptoms.
A study found that pregnant women with high blood pressure who received tight blood pressure control immediately after pregnancy had lower blood pressure levels and improved cardiac function compared to those with usual care. This could lead to a reduced risk of cardiovascular disease, including heart attacks and strokes.
A randomized clinical trial found that self-monitoring and physician-guided titration of antihypertensive medications reduced postpartum blood pressure compared to usual care. The study involved 220 participants in the UK and showed promising results for long-term blood pressure control.
Experts call for urgent measures to address discrimination against patients fleeing war or conflict zones, those with serious mental illnesses, and frail elderly patients. Guidelines for treating advanced breast cancer should prioritize patient preferences and involve multidisciplinary care teams.
A recent study led by Duke-NUS Medical School found that prior maternal dengue immunity substantially increases the risk of severe birth defects induced by Zika virus infection during pregnancy.
