Researchers found that eliminating cost sharing for contraception resulted in higher birth rates among low-income and middle-income women, but not among high-income women. The study suggests that increased access to affordable contraception may contribute to a decline in unintended pregnancies.
A prospective study of 69 couples found that female partners overestimated their IVF live birth rates by 34%, while male partners expected a 54% higher rate. The study highlights the need for clinics to set realistic expectations and provide individualized prognosis to avoid disappointment.
Research found that vitrification technology is safe for embryos, but storing them for longer periods reduces chances of pregnancy and live birth. The study analyzed outcomes from 24,698 patients and found lower implantation, clinical pregnancy, and live birth rates with longer storage times.
Women with postpartum psychiatric disorders are less likely to have more children, with 69% still choosing to have a second child. The study found that nearly half of women with psychiatric problems had a reduced live birth rate due to hospitalization or fear of relapse.
A large-scale study found that long-term cryopreservation of semen does not affect pregnancy and live birth rates in women using donor sperm. The study analyzed 119,558 semen samples stored for up to 15 years and found similar success rates in IVF and donor insemination, despite a decline in frozen sperm survival rate over time.
A study found a 10% reduction in monthly birth rates in Fukushima City following the 2011 nuclear disaster, but rates recovered similar to pre-disaster levels after several years. The authors suggest this may indicate post-disaster rebuilding efforts.
The largest randomized trial on genetic screening before embryo transfer found no difference in live birth rates between groups with and without the procedure. However, there was a lower miscarriage rate and fewer embryo transfers in the group that received genetic screening.
Researchers found 119,095 fewer births than expected due to pregnancy postponement and increased safe abortions. Zika awareness likely contributed to the decrease in birth rates.
A randomized clinical trial of 824 women undergoing IVF found no significant difference in live birth rates between those receiving acupuncture and sham acupuncture. The study, published in JAMA, provides insight into the effectiveness of acupuncture in fertility treatments.
Researchers found a strong link between low vitamin D concentrations and lower live birth rates after ART compared to those with sufficient levels. Women with adequate vitamin D were 34% more likely to have a positive pregnancy test and 46% more likely to achieve a clinical pregnancy.
The number of children admitted to intensive care has risen sharply since 2009, defying expectations of population growth or birth rate increases. The trend, driven by higher admission rates among younger children and those with breathing or cardiovascular problems, poses a significant challenge for the NHS.
Researchers found that teen fathers are less likely to provide financial support, but teen parents are staying in school longer and have seen an uptick in income. The study suggests that factors like the 'cougar effect' and improved reporting of teenage males may contribute to the growth in teenage paternity.
A higher number of eggs retrieved in IVF treatment is linked to more chromosomally normal embryos available for transfer. The benefit of a greater oocyte yield decreases with advancing female age.
A new study of almost 19,000 IVF treatment cycles reveals that the age of the male partner significantly affects live birth success rate. The study found a decline in cumulative incidence of live birth with increasing male partner age, particularly among women aged 30-35 and those over 40.
A new study by Indiana University researchers found that increasing the minimum wage would likely reduce the US adolescent birth rate by about 2%. This translates to approximately 5,000 fewer births annually. Higher wages can motivate teens to work and delay childbearing or prioritize leisure time over parenthood.
A global study found a significant association between rising national income, education expenditures, and declining rates of adolescent childbearing. The median adolescent birth rate dropped by 40% from 1990 to 2012, with the highest rates in Sub-Saharan Africa and lowest in Europe and Central Asia.
A study found late preterm and early term birth rates decreased in the US between 2006 and 2014. Clinician-initiated obstetric interventions also declined, particularly among births over 37 weeks, suggesting a positive association with delayed interventions.
A recent ESHRE study found that human growth hormone did not improve live birth rates in women having difficulty conceiving, with a clinical pregnancy rate of 14% in the treatment group and 11% in the placebo group. Poor responders are a challenging group to treat, accounting for up to 30% of patients who respond poorly to treatment.
US out-of-hospital birth rates increased to nearly 1.5% of total births in 2014, with non-Hispanic white women experiencing the largest growth. Many women face difficulty accessing insurance coverage for out-of-hospital births, leading to high self-pay rates.
The US twin birth rate has surged over the last 30 years, partly due to reproductive technologies like IVF. Implementing single embryo transfer IVF could reduce unintended twin births by minimizing serious medical complications. This approach is recommended for insurance coverage and curtails the national twin birth rate.
A new scientific review article reveals that endocrine-disrupting chemicals are contributing to declining fertility rates in industrialized countries. Poor semen quality and higher incidences of testicular cancer have been linked to environmental factors, with average men experiencing lower levels of testosterone.
A Canadian study found that black women are at a higher risk of preterm birth than white women, with rates mirroring those in the US. The study analyzed data from the Canadian Live Birth database and found that black women had an 8.9% preterm birth rate, compared to 5.9% for white women.
The US earns a 'C' grade for its preterm birth rate, with racial and ethnic disparities persisting in many states. Cities like Portland, Oregon, and St. Paul, Minnesota, have lower rates, while Shreveport, Louisiana, has the highest rate among major cities.
A study published in JAMA found that using frozen donor eggs for IVF is linked to lower live birth rates compared to fresh eggs. The study analyzed data from over 11,000 cycles and found that per started cycle, the live birth rate was 43% with frozen eggs vs 50% with fresh eggs.
A study by Dr. Marta Devesa found that IVF cumulative live birth rates decline significantly with age, especially in women using their own eggs, with a 3% chance of success at 44 and over. In contrast, egg donation shows higher success rates, making it a viable alternative for older patients.
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.
The national preterm birth rate fell to 11.4% in 2013, beating the federal Healthy People 2020 goal seven years ahead of schedule. Despite this progress, the US still ranks among high resource countries with one of the highest preterm birth rates.
A global study from University of California, Berkeley suggests that a moderately low birth rate can actually boost a country's overall standard of living. Researchers found that families bear the costs of raising children, while governments should adjust policies to accommodate population aging.
New research from Princeton University shows that recessions have a profound impact on fertility, leading to lower birth rates in the short and long term. Women who experience high unemployment during their 20s are more likely to remain childless by age 40, with the effects increasing exponentially over time.
A study by Dr Ana Cobo found that cumulative live birth rates increase progressively with the number of vitrified eggs used, reaching a plateau at 97.3% with 40 eggs. Egg banking can provide a large pool of donor eggs without synchronizing cycles, making it a more efficient and safer process.
Researchers analyzed human remains in the Four Corners region, finding a centuries-long population growth and subsequent collapse due to overpopulation and environmental degradation. The study highlights the importance of considering population growth's consequences for modern societies.
Researchers charted an ancient baby boom in the southwestern US among Native Americans between 500 to 1300 A.D. Birth rates likely exceeded the highest in the world today, driven by early features of civilization such as farming and food storage. However, a crash followed, offering a warning sign about the dangers of overpopulation.
A study published in The BMJ found a significant increase in births in Catalonia nine months after FC Barcelona won three major football trophies. Births rose by 16% in February 2010, with some areas experiencing even higher increases, although the findings fall short of earlier media reports.
A recent study published in the Clinical Journal of the American Society of Nephrology found that women with advanced kidney disease who start dialysis during pregnancy have a higher live birth rate compared to those already on dialysis. This discovery may help guide care for young women who need dialysis.
The US preterm birth rate has dropped to its lowest level in 15 years, but the country still earns a 'C' grade. Since 2006, about 176,000 fewer babies have been born too soon, potentially saving $9 billion in health and societal costs.
A new study by Max-Planck-Gesellschaft researchers finds that rising unemployment rates in Europe have led to a decrease in fertility, with young adults being the most affected. The drop in children per woman was strongest for first births, with many postponing family formation.
A study suggests that limiting non-medically indicated caesareans and induced labor can reduce preterm births in high-income countries. Implementing evidence-based interventions could avert around 58,000 preterm births annually, saving $3 billion in economic costs.
Experts claim that lowering preterm birth rates by an average of 5 percent across 39 high-resource countries can prevent prematurity for 58,000 babies a year. Combining five proven interventions can lower the preterm rate and save about $3 billion in health costs.
A new study reveals that improving water supplies in rural African villages can lead to higher birth rates, larger family sizes, and increased household shortages. As a result, young adults are more likely to migrate to cities, exacerbating poverty and urbanization issues.
The US preterm birth rate dropped for the fifth consecutive year in 2011 to 11.7 percent, giving thousands more babies a healthy start in life and saving billions in health and social costs. Four states earned an 'A' on the March of Dimes Premature Birth Report Card, while the US earned a 'C', despite progress.
A study found that higher public reimbursement for fertility treatment increases access to care, reducing unmet needs in subfertile populations. Countries with more generous funding policies have a higher volume of ART cycles performed and lower rates of multiple births.
A massive study of nearly 250,000 U.S. women found that live birth rates for fertility treatment can approach natural fertility rates with favorable patient and embryo characteristics. The study highlights the importance of factors such as age and embryo quality in determining success rates.
Preterm birth rates have decreased in Croatia, Ecuador, and Estonia over the past 20 years, with only six countries showing a decrease. The preterm birth rate increased in most countries, with European nations experiencing significant rises, particularly Cyprus and Slovenia.
The US has the highest preterm birth rate among 130 countries, with 12.0 preterm births per 100 live births. Nearly half a million babies are born too soon in the US each year, resulting in significant human and economic costs.
A recent US study found that teens in areas of high income inequality are more likely to have a baby. Low-income teens are more likely to give birth rather than investing in their own economic progress. The study suggests that teen childbearing is a symptom, not a cause of poverty.
The March of Dimes has launched a virtual network to prevent preterm birth, with the goal of reducing the rate to 9.6%. The network aims to share information on successful programs and policies to prevent preterm births, resulting in better health outcomes for babies.
The US preterm birth rate has improved by nearly 5% between 2006 and 2009, with 40,000 more babies receiving a healthy start in life. This improvement is attributed to various health interventions and treatments, including progesterone, which have reduced medically unnecessary c-sections and inductions.
A recent study confirms shark populations are in trouble worldwide, with significant declines observed on the Great Barrier Reef. The research used innovative methods to estimate population growth rates, finding that sharks are declining rapidly due to fishing.
Researchers found a link between fibroids and recurrent miscarriages, with removal of distorting fibroids reducing risk of miscarriage in second trimester. Removing such fibroids also doubled live birth rate in subsequent pregnancies for women with unexplained RM.
A study analyzing over 400,000 IVF cycles in the UK found that aiming for 15 eggs retrieved per cycle maximizes live birth rates while minimizing ovarian hyperstimulation syndrome risk. The number of eggs above 20 leads to a decline in live birth rates.
Astronomers from Bonn and St. Andrews discover that the discrepancy between calculated and observed star numbers may be due to an overestimation of stellar crowding, a phenomenon where young stars are born in groups, leading to more massive stars being overlooked.
The US saw a two-year decline in preterm birth rates, primarily among babies born just weeks early, while many states improved in at least one contributing factor. The overall national rate remains high compared to top-scoring countries.
The US received a 'D' grade on the March of Dimes Premature Birth Report Card, with over half a million newborns not receiving a healthy start. Seven states improved their preterm birth rates by reducing smoking, uninsured rates, and late preterm births.
The new White Paper reveals an estimated 13 million babies worldwide were born preterm in 2005, with one million deaths attributed to preterm birth. Premature births face serious lifelong health risks and contribute significantly to global healthcare costs.
Researchers found a strong association between teenage birth rates and state-level measures of religiosity in the US. Conservative religious beliefs are strongly predicted to influence teen birth rates, even after controlling for income differences.
A recent study found that nearly all human embryos produced through IVF have chromosomal problems, rendering current preimplantation genetic screening techniques useless. Chromosomal instability is likely responsible for low fertility rates and high abortion rates, and could impact spontaneous pregnancies as well.
Researchers followed over 6,000 IVF patients through six cycles, finding live birth rates range from 65-86% for younger women and 23-42% for those aged 40+, with most births being singletons.
The US received an overall 'D' grade on the first Premature Birth Report Card, with 18 states and Puerto Rico receiving failing grades. The report highlights contributing factors and prevention opportunities, including smoking and uninsured women of childbearing age.
A new Penn State study found that a variety of recruitment strategies are used to recruit and retain older workers, including employee incentives and flexible work schedules. Employers can benefit from tapping into the experience and knowledge of baby boomers and other older workers.
Preimplantation genetic screening (PGS) does not increase ongoing pregnancy or live birth rates in women over 35 undergoing IVF. The technique's effectiveness has been called into question due to various limitations, including the potential for biopsy errors and chromosomal analysis biases.
