Researchers at the University of Kent identified strong evidence-based benefits of preimplantation genetic testing for aneuploidy (PGT-A) in IVF. Live birth rates per embryo transferred and per treatment cycle were significantly higher with PGT-A compared to regular IVF, especially in women over 40.
A recent study suggests that infants conceived through in vitro fertilization (IVF) may be at a higher risk of developing craniosynostosis, a type of skull deformity. The four percent prevalence rate among IVF-conceived infants is considerably higher than the estimated one case per 1,800 to 2,200 births. Further studies are needed to c...
Researchers at RMIT University have discovered a Teflon-like molecule on the womb's surface that decreases at a certain point in the menstrual cycle, opening the 'golden window' for pregnancy success. This finding could lead to improved IVF success rates and potentially treat underlying causes of infertility.
A mathematical model developed by Rutgers University scientists can help explain why many pregnancies and IVF attempts fail. The study highlights the importance of understanding errors in female cell division, which increase with age and are linked to aneuploidy, a leading cause of early miscarriage and IVF failure.
A study of almost 276,000 children found a small association between IVF conception and an increased risk of childhood cancer, mostly rare tumor types. The link was limited to the first decade of life and was found in only a subset of cancers.
Women who undergo infertility treatment are more likely to experience severe pregnancy complications, such as postpartum hemorrhage and sepsis. Researchers found a 40% increased risk among women who received in vitro fertilization compared to those without treatment.
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.
A study published in the New England Journal of Medicine found that women using IVF have similar chances of having a baby with fresh or frozen embryos. The research, involving 2,157 women, showed no significant difference in live birth rates between the two groups.
A new analysis of published studies found a 45% increased risk of congenital heart defects in IVF-conceived children compared to spontaneously conceived children. The study included 25,856 children from IVF and 287,995 from spontaneous conception, finding 1.30% and 0.68% cases of congenital heart defects respectively.
A new analysis found an approximate 80% increased risk of spontaneous preterm birth when women conceive through in vitro fertilization. This risk is significant enough to warrant ultrasound cervical screening to apply preventive strategies.
Researchers at Baylor College of Medicine discovered that follistatin promotes decidualization and supports embryo implantation. In a mouse model, female mice lacking follistatin produced fewer pups and failed to attach embryos to the uterine wall.
A recent study published in JAMA Network found that women with insurance coverage for IVF were more likely to attempt the procedure again and had a higher probability of live birth compared to those who self-paid. The research, conducted at Washington University in St. Louis, included 1,572 women and observed them through four cycles.
A $440,000 NIH grant is supporting a 3-year study examining the impact of cigarette smoke and genetic factors on female fertility. The researchers will assess ovarian reserve, in vitro fertilization success rates, and NAT2 genotype to better understand the relationship between smoking, genetics, and infertility.
A study of 1,508 infertile women with PCOS found that frozen embryo transfers had lower rates of ovarian hyperstimulation syndrome and pregnancy complications compared to fresh embryo transfers. Women with PCOS who received frozen embryos also had higher rates of live births and better birth weights.
