The research found a positive correlation between the number of uterine contractions and the rate of clinical pregnancy, as well as live births following artificial insemination.
A large-scale study led by the University of Exeter has found that boys are more likely to be stillborn than girls, with a risk increase of about ten percent. The study reviewed over 30 million births globally and found this disparity results in approximately 100,000 additional male babies lost per year.
A recent study found that tropical rickettsial illnesses, such as scrub typhus and murine typhus, can cause poor pregnancy outcomes, including stillbirth and premature birth. The study highlights the need for more research on the impact of these illnesses on pregnancy outcomes in South-East Asia.

A new study led by Harvard School of Public Health found that the use of antiretroviral medications during early pregnancy does not significantly increase the risk of birth defects in infants. However, one specific ARV drug, atazanavir, was associated with a higher risk of birth defects, particularly musculoskeletal and skin anomalies.
A new study has found that the extracellular matrix component hyaluronan (HA) in the cervix provides protection against infection, which can lead to preterm birth. Mice unable to produce HA had abnormal cervical structures and higher preterm birth rates in response to infection.
A study by Elard Koch reveals that hospital discharges due to abortion complications decreased significantly in Chile since 2001. The decline was attributed to improved maternal health policies and increased women's educational level, rather than changes in abortion laws.

A study of 77 women who died during pregnancy or childbirth found no racial difference in the risk of pregnancy-related death, contrary to national trends. However, distance from the hospital was significantly associated with an increased risk of mortality, suggesting that differences in health care access may be a contributing factor.
A new study examines changes in alcohol use among women with unwanted pregnancies and finds that most quit or reduce consumption upon discovery. However, some may substitute alcohol for drugs. The study's results highlight the need for interventions to help these women reduce their drinking while pregnant.

The researchers propose three possible explanations for this trend: legacy concerns, public relations considerations, and social schedules.
A new study found that providing free contraception and education on various methods significantly reduced teen pregnancies, births, and abortions. Among participants, 72% opted for long-acting forms like IUDs or implants, leading to a 34-per-1,000 pregnancy rate among teens compared to 158.5 in 2008.
Research in mice suggests that maternal cigarette smoking can affect the fertility of male offspring, causing reduced sperm counts, poor sperm shape, and impaired fertility. The study's findings have implications for human health, particularly for men who were exposed to cigarette toxins in the womb.

The study estimated that nearly half of all diabetic pregnancies could be prevented through these low-risk lifestyle factors.
A new BU study found that prenatal exposure to tetrachloroethylene in drinking water may increase the risk of stillbirth and placental abruption. The study, which compared over 2,000 pregnancies, found a significant association between PCE exposure and an elevated risk of these pregnancy complications.
Researchers detected a distinctive DNA signature in children born after the massive Quebec ice storm, linked to maternal hardship and stress. The study found that objective stress exposure, not emotional distress, caused long-lasting changes in the epigenome of their babies.
Children exposed to chemotherapy or radiotherapy in utero suffer no negative impacts on mental or cardiac development, according to international studies presented at ESMO 2014. These findings confirm that chemotherapy and radiotherapy during pregnancy do not endanger the fetus and its subsequent development.
A recent study found that mefloquine, an antimalarial drug, was not effective as an alternative to sulfadoxine-pyrimethamine (SP) for malaria prevention during pregnancy. Despite its safety profile, the drug showed poor tolerability and limited benefits for fetal health in HIV-positive women.
A study of pregnant women receiving computerized decision-support guides found significantly less invasive diagnostic testing compared to those without. The intervention resulted in more women choosing no or screening-only testing strategies.
A new study found that pregnant women's immune cells produce more cytokines and chemokines when exposed to flu viruses, leading to a hyperinflammatory response. This unexpected finding highlights the need for new treatment approaches for severe influenza in pregnancy.
A flu shot is crucial for pregnant women to prevent serious illness and protect their babies from influenza. Vaccinated moms also have a lower risk of flu-related hospitalizations for chronic asthma, heart conditions, diabetes, and other health issues.
The article emphasizes the need for improved access to female-controlled contraceptive methods to counteract reproductive health risks caused by intimate partner violence. Clinicians can help women and girls regain control over their reproductive health through availability of effective contraceptives.
A study found that antenatal magnesium sulfate treatment was not associated with improved outcomes in children born at less than 28 weeks' gestation. Despite its neuroprotective effects for preterm fetuses, the treatment had no long-term benefits on neurological, behavioral, growth, or functional outcomes.
A recent UChicago study found that pregnant teens will turn to supportive parents and adults in their lives for help making the abortion decision. The majority of young women involved a parent or guardian, driven by factors like close relationships, need for logistics assistance, and concerns about parental interference.
Adequate vitamin E levels are critical for fetal development and nervous system health. Inadequate intake is linked to increased infection, anemia, stunting of growth, and poor pregnancy outcomes.
Research on over 4,000 participants found that binge drinking during pregnancy can lead to increased hyperactivity and inattention in children, affecting their academic performance. The study suggests that exposure to alcohol in the womb may be a risk factor for long-term mental health issues.

Women with short cervices who are pregnant with twins saw a 50% decrease in preterm birth, highlighting a potential game-changer in obstetric care.
Experts recommend prioritizing pregnant women for long-lasting insecticide treated nets through antenatal care clinics. This distribution strategy can help improve maternal, neonatal, and infant health by preventing malaria, which has adverse effects on mothers and infants.
A phase III trial found that continuous REVLIMID (lenalidomide) with dexamethasone improved progression-free survival and reduced risk of disease progression compared to standard treatment. Patients treated with continuous REVLIMID plus dexamethasone showed a significant reduction in risk of progression or death.
A study published in Epidemiology found that exposure to parabens and triclosan during pregnancy may hinder boys' growth, while bisphenol A was not associated with any significant impact. The research also suggested a link between parabens and increased weight at birth and three years old.

New research found an epigenetic link between a mother's diet and an offspring's risk of future obesity. Excess methylation on the Pomc gene blocks its expression, leading to delayed satiety response and increased food intake.
A study of 158 pregnant teenagers found nearly half engaged in pica behaviors, such as consuming ice and starches, which are also associated with lower iron levels. This can lead to anemia, premature births, and low birth weights, posing a significant risk to infant mortality rates.
A new study by CU Denver researcher Zaneta Thayer found that poor women experience higher cortisol levels during pregnancy, giving birth to infants with elevated cortisol responses to stress. These early life disparities can lead to serious disease later in life and highlight the need for stress reduction and social support.
Seroprevalence of HSV-1 remains stable, while HSV-2 decreases significantly among all races, with a greater decline for white women than black women. The study found no association between the decline in HSV-2 prevalence and a decrease in neonatal herpes cases.
