Scientists at the University of Sheffield have identified a protein, involved in the development of the human placenta, that may also help embryos implant in the womb - something which could improve treatments for recurrent miscarriages and pre-eclampsia.
Depression and anxiety, and not necessarily the use of antidepressant medication, are associated with lower pregnancy and live birth rates following in vitro fertilisation, according to a large register study from Karolinska Institutet in Sweden. The findings are published in the journal Fertility & Sterility and can be of interest to clinicians treating infertility and for women with depression or anxiety planning to undergo fertility treatment.
Childhood cancer survivors have long been concerned about their future ability to reproduce. New research published in The Lancet Oncology puts some of these worries to bed but at the same time confirms others.
The twin birth rate in the U.S. has surged over the last 30 years, mostly because of reproductive technologies including in vitro fertilization. Though it's partly the cause, IVF could also be the most promising solution to reducing unintended twin births, argues Dr. Eli Adashi in a new editorial in the American Journal of Obstetrics & Gynecology.
Andrew Wilkie, Nuffield professor of pathology at the University of Oxford in the UK, and colleagues describe their findings in a paper published in the Proceedings of the National Academy of Sciences.
When prospective parents who are unable to conceive a child on their own consult me for assistance, I am excited to help them build their families. But for them, dealing with the challenges of infertility can be as stressful as having cancer. Fortunately, the latest advances in in vitro fertilization (IVF) are giving them a better chance than ever of achieving their dreams.
This systematic review has found that single pregnancies after transfer of frozen thawed embryos were associated with a lower risk of perinatal mortality, small for gestational age babies, preterm birth (defined as before 37 weeks’ gestation), low birth weight (defined as less than 2,500g) and antepartum haemorrhage (bleeding during pregnancy).
Experts in in-vitro fertilization (IVF) from UC San Francisco have discovered a pattern of protein secretion during egg maturation that they say has the possibility of leading to a new, non-invasive test to evaluate the fitness of eggs before they are fertilized in the clinic.
More than 10% of American women aged 15-44 struggle to conceive or maintain full-term pregnancies, according to the Centers for Disease Control and Prevention (CDC). Assisted reproductive technology (ART), through which eggs are fertilized with sperm in a lab and then returned to a woman's uterus, is often the last resort for reproductively-challenged couples.
New research could help to explain why pregnancy becomes less likely as women age and why IVF so often fails.
Scientists have shown for the first time that hormones produced inside the womb play a pivotal role in the early stages of pregnancy.
