Prospective birth control pill for men has its origin in an arrow poison
Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.

New report calls into question effectiveness of pregnancy anti-nausea drug
Previously unpublished information from the clinical trial that the US Food and Drug Administration relied on to approve the most commonly prescribed medicine for nausea in pregnancy indicates the drug is not effective, a new report says.

New treatment target for melanoma identified
Researchers have identified a new therapeutic target for the treatment of melanoma. For decades, research has associated female sex and a history of previous pregnancy with better outcomes after a melanoma diagnosis. Now, a research team says it may have determined the reason for the melanoma-protective effect.

Starting periods before age of 12 linked to heightened risk of heart disease and stroke
Starting periods early -- before the age of 12 -- is linked to a heightened risk of heart disease and stroke in later life.

Preterm babies may suffer setbacks in auditory brain development, speech
Preterm babies born early in the third trimester of pregnancy are likely to experience delays in the development of the auditory cortex, a brain region essential to hearing and understanding sound, a new study reveals. Such delays are associated with speech and language impairments at age 2, the researchers found.

Stem cell-rich cord blood donations could increase by 'nudging' parents, study suggests
A two-year study of expectant mothers in Milan, Italy, has found that cord blood donations increased significantly when parents received information about the procedure and 'prompts' to indicate their interest in donating at both early and late stages of their pregnancies.

Pregnant women in NC exposed to less secondhand nicotine after ‘smoking ban’
A new study has found pregnant women experienced less secondhand smoke exposure since the 2009 passage of the ‘smoking ban’ in North Carolina, which outlawed smoking inside public places such as bars and restaurants.

Frozen embryos result in just as many live births in IVF
Freezing and subsequent transfer of embryos gives infertile couples just as much of a chance of having a child as using fresh embryos for in vitro fertilization (IVF), researchers have found.

Common pain reliever use during pregnancy linked to language delay in girls
In the first study of its kind, researchers have found an elevated rate of language delay in girls at 30 months old born to mothers who used acetaminophen during pregnancy, but not in boys.

Conception during IUD use increases risks to mother and infant
Women who conceive while using an intrauterine contraceptive device (IUD) have a greater risk of preterm delivery, low birth weight babies, bacterial infections, or losing a fetus, according to researchers.

Taking paracetamol during pregnancy may reduce fertility of daughters
Taking paracetamol during pregnancy may impair the future fertility of female offspring, according to a new review. The article reviews three separate rodent studies that all report altered development in the reproductive systems of female offspring from mothers given paracetamol during pregnancy, which may impair their fertility in adulthood.

How Zika infection drives fetal demise
An interferon cell receptor spurs cell suicide in fetuses infected with the Zika virus and could play a role in certain pregnancy complications.

Advanced MRI can detect placental perfusion abnormalities in pregnancies complicated by fetal CHD
In pregnancies complicated by fetal congenital heart disease, global placental perfusion was significantly decreased and regional variation of placental perfusion significantly increased as pregnancies progressed, findings that point to non-invasive imaging providing an early warning of placental dysfunction.

Eating more foods with choline during pregnancy could boost baby’s brain
When expectant mothers consume sufficient amounts of the nutrient choline during pregnancy, their offspring gain enduring cognitive benefits, a new study suggests.

Sperm-sorting device could improve IVF success
Women undergoing in vitro fertilization (IVF) may become pregnant with fewer treatment cycles, thanks to a new device that uses an 'obstacle course' to sort and select faster and healthier sperm cells for use in IVF treatment.

Novel complementary effects of estrogen treatment in multiple sclerosis
A study reveals the cellular basis for how the hormone protects against damage to the central nervous system.

Topiramate in early pregnancy increases risk of oral clefts
A new study suggests that using topiramate in early pregnancy, particularly at the high doses used for epilepsy, increases the risk of oral clefts.

Neuroscientists shed light on causes of postpartum depression using new research model
Postpartum depression strikes nearly one in five new mothers. Stress is a significant risk factor for this complex condition. Neuroscientists have generated a novel preclinical model of postpartum depression and demonstrated involvement of the hypothalamic-pituitary-adrenal axis (the neuroendocrine system that mediates physiological response to stress and is normally suppressed during and after pregnancy). These findings in mice provide the first empirical evidence that disruption of this system engenders behaviors mimicking human postpartum depression.

Taking folic acid in late pregnancy may increase childhood allergy risk
Taking folic acid in late pregnancy may increase the risk of allergies in offspring affected by intrauterine growth restriction (IUGR), new research indicates.

Harnessing sperm to treat gynecological diseases
Delivering drugs specifically to cancer cells is one approach researchers are taking to minimize treatment side effects. Stem cells, bacteria and other carriers have been tested as tiny delivery vehicles. Now a new potential drug carrier to treat gynecological conditions has joined the fleet: sperm. Scientists report that they have exploited the swimming power of sperm to ferry a cancer drug directly to a cervical tumor in lab tests.

Struggling to get your kids to eat healthy? 'Don't give up!' researchers say
Varied diets and persistence in exposing infants and children to healthy foods, even when they don't like them at first, are key to promoting healthy eating behaviors, a new review paper has concluded.

Using MRI to understand why some women go into early labor
Scientists are using the latest imaging techniques usually used to map the brain to try and understand why some pregnant women miscarry or go into early labor.

Underactive thyroid within normal range may affect woman's ability to conceive
New research suggests that a slightly underactive thyroid may affect a women's ability to become pregnant -- even when the gland is functioning at the low end of the normal range.

Immune cells in the uterus help nourish fetus during early pregnancy
Natural killer cells are among the most abundant immune cells in the uterus during the first trimester of pregnancy, but their numbers decline substantially after the placenta forms. A new study shows that this cell population helps to optimize maternal nourishment of the fetus at early stages of development. The researchers identified uterine natural killer cells that secrete growth-promoting factors, and demonstrated that transfer of these cells can reverse impaired fetal growth in pregnant mice.

Some newborns with chronic illness show signs of serious sleep problems at birth
New parents often hear about how important sleep is for their babies' development -- but some newborns may have more serious sleep challenges than others. A new study finds that babies with spina bifida have early symptoms of sleep-disordered breathing that could contribute to lifelong issues with neurodevelopment.

Genetic instructions from mom set the pattern for embryonic development
A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene.
