The global prevalence of fetal alcohol spectrum disorder (FASD) is estimated to be about 8 per 1,000 in the general population, with 1 in every 13 pregnant women delivering a child with FASD. Higher prevalence rates are observed in special populations, such as Aboriginal populations and children in care.

Women reported feeling pressure to lose weight quickly after childbirth and being influenced by social media, which can foster competition and guilt.
A Norwegian study found that increasing Body Mass Index above one unit from first to second pregnancy drastically increases the risk of developing gestational diabetes mellitus (GDM). Women with BMI less than 25 in first pregnancy showed a strongest risk associated with weight gain, while overweight women who reduced their BMI by more ...
Researchers have developed a mouse model to study Zika virus transmission, finding that the virus can be transmitted sexually from males to females and vertically from pregnant women to their fetuses. The study suggests that the placenta may be a key barrier in preventing Zika virus infection of the fetus.
The study found a substantial increase in neonatal abstinence syndrome among infants whose mothers were prescribed opioids and psychotropic medications. The absolute risk was highest among women exposed to gabapentin, with concurrent exposure to psychotropic medications increasing severity of withdrawal symptoms.
Research finds that meiosis, a key process in sexual reproduction, takes a heavy toll on offspring viability, affecting various organisms including humans and non-human animals. The study suggests that the advantages of sex must outweigh its drawbacks to be advantageous for evolution.
Researchers found that prior vaccination in pregnant women did not significantly affect the transfer of flu antibodies to their babies, contradicting initial concerns. Weakened maternal immune responses from repeated flu shots also hindered peak antibody levels.
A study by Stanford Medicine and Celmatix Inc. found that elective freezing of IVF embryos can improve pregnancy rates in women with high progesterone levels and are over 35. Freezing the embryos before transfer may give hormones a chance to fall to more hospitable levels for implantation.
A new study published in PLOS Medicine found that women who gained more than one BMI unit between pregnancies had a doubled risk of developing gestational diabetes. The increased risks were strongest in women with a low BMI, and evidence suggested that reducing weight between pregnancies can help prevent GDM.
Research in sheep model reveals babies born to overweight, obese mothers have less mature lungs, producing less surfactant and fewer cells that make it. This can lead to lung problems at birth and later during infancy and childhood.
A new study found that Oregon's CCO model significantly improves the timeliness of prenatal care for pregnant women on Medicaid. The study reveals that more women began prenatal care in the first trimester, particularly among white and Asian women and those in urban areas.
Exposure to air pollution during the first two trimesters of pregnancy has been shown to increase risk for preterm birth and low birth weight. The study's findings also suggest that exposure to fine particulate matter (PM2.5) can lead to decreased body length, placental weight, and anogenital distance.
A new study found that calves born to cows experiencing heat stress during early pregnancy exhibit related effects throughout their lives. Milk production and fat yield are higher for winter-conceived calves compared to summer-conceived calves.
A study found that pregnant women who took antidepressants were 45% more likely to have children diagnosed with autism, but the effect was limited. The research suggests that only a small proportion of cases would be prevented if antidepressant use was completely cut off during pregnancy.
A US study of the dapivirine ring among lactating women found that the drug is absorbed in very low concentrations into breastmilk. The results support further studies on the safety of the ring during breastfeeding and pregnancy, which are planned to be conducted in Africa.
Researchers found standard maternal screening methods can overlook cases of congenital CMV infection in up to 70% of women. A more comprehensive approach, including PCR tests on all newborns, is needed for early detection and treatment.

A recent survey found that adolescent girls seeking medical care in emergency departments are open to receiving information on preventing pregnancy. The study, which analyzed data from 219 non-pregnant females aged 14-21, revealed that 72% of participants wanted EDs to provide pregnancy prevention and contraception info.
A new study reveals that restless legs syndrome (RLS) is common in pregnant women, associated with poor sleep quality, excessive daytime sleepiness, and poor daytime function. RLS symptoms were experienced by half of the women with severe symptoms, highlighting the need for identification and treatment.

Vitamin D insufficiency was also associated with impaired social development at age 3½ years, while no associations were found at older ages.
Women who breastfed for 15 months or more have a reduced risk of developing multiple sclerosis (MS) compared to those with no breastfeeding. The study, published in Neurology, found that this association held true even when considering factors like age and ovulation.
A study in mice found that antibiotics taken late in pregnancy and during nursing can alter the gut microbiome and increase the risk of inflammatory bowel disease (IBD) in offspring. The antibiotic treatment also caused lasting changes in the mothers' gut microbiomes, which were passed on to their offspring.
Researchers at WashU Medicine found that hydroxychloroquine effectively blocks viral transmission to the fetus, protecting it from Zika infection. The study used mouse models to demonstrate that suppressing autophagy promotes Zika virus survival and infection in the placenta.
A malaria drug approved for treating certain autoimmune diseases during pregnancy may also reduce the transmission of Zika virus from mother to fetus. The study found that inhibiting autophagy with hydroxychloroquine limited Zika infection in fetal head and led to a larger body size, suggesting potential benefits.

The association was independent of other risk factors often present in smokers, suggesting a small to moderate causal effect on offspring's behavior.
A new study by UCR psychology professor Kelly Huffman found that prenatal ethanol exposure causes abnormalities in the brain and behavior that may be passed on for many generations. The research shows that drinking alcohol during pregnancy can lead to adverse outcomes in future grand- and even great-grandchildren, including reduced bod...
Researchers found that maternal antibodies against HSV-1 can travel to the nervous systems of unborn babies, preventing the development and spread of infection during birth. This protection may help prevent serious brain disease related to these conditions in fetuses and newborns.
A recent study published in the European Respiratory Journal found a strong association between high maternal sugar intake during pregnancy and an increased risk of allergy and allergic asthma in offspring. The research, which analyzed data from over 9,000 mother-child pairs, suggests that high fructose intake may cause a persistent po...
A new study reveals that chromosomally 'abnormal' embryos can still result in pregnancy through IVF, with the potential for self-correction and development into a healthy fetus. The extent of mosaicism influences clinical outcomes, suggesting priority should be given to mosaic embryos with low aneuploidy levels.
Spain now holds the pace of European ART with over 100,000 cycles performed annually, resulting in a steady pregnancy rate of around 35%. The data collected by ESHRE also reveals that IVF remains more successful than ICSI, but pregnancy rates from egg donation continue to rise.
A study has shown that an inexpensive fertility drug can be just as effective as more recent reproductive hormones in treating unexplained infertility. The 50-year-old drug, taken orally, was found to have a comparable pregnancy rate to newer hormones used in intrauterine insemination (IUI) with ovarian stimulation.
A large population study found that female cancer survivors are 38% less likely to achieve a pregnancy than women in the general population. The detrimental effect on fertility was evident in almost all types of cancer diagnosed, with variations between different cancer diagnoses.
