Active and passive smoking are linked to infertility problems and a hastening of the natural menopause before the age of 50, a large study finds.
Fertility experts in Southampton and the Netherlands have identified a specific genetic pattern in the womb that could predict whether or not IVF treatment is likely to be successful.
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.
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. But the physical, emotional, and financial toll they exact is high because the success rates of ART treatments are low -- only 20-30%, according to the CDC.
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.
Women who drink 14 or more servings of alcohol a week are slightly more likely to have reduced fertility, suggests a new study. In developed countries, up to 24% of couples experience infertility, defined as time to pregnancy of 12 months or more.
