  • Depression and anxiety may reduce chances of IVF pregnancy

    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 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.

  • Discovery may lead to better egg screening and IVF outcomes

    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).
