Of the women who carry the mutated BRCA1/2 genes, 45-65 percent will develop breast cancer, and 15-39 percent will develop ovarian cancer. Many women elect to undergo preventive surgeries that can significantly increase life expectancy, but can impact later fertility. However, few guidelines exist on the optimal age to undergo these procedures, and in what sequence. A new study in the INFORMS journal Decision Analysis provides insight to help physicians and patients make better-informed choices.
Many pregnant women undergo some form of prenatal testing before their children are born. The information that expectant mothers gain from these tests vary, from the baby's gender to genetic defects. But the tests are often invasive, which can potentially harm the fetus and the mother. Now, one group reports in ACS Nano that they have developed a device that provides sensitive results, but in a less invasive way: a blood test.
Children conceived using donor sperm have similar health and well-being to the general population, according to a study published in Reproductive BioMedicine Online.
Many women are turning to egg freezing to promote fertility, but what happens when it isn't an option because of special medical conditions? And, what option is there for women who want to preserve hormonal function, not just fertility? Ovarian tissue freezing can deliver these outcomes but has been considered experimental until now. According to a new study, nearly 4 out of 10 women who undergo the procedure are able to have children later on.
When a pregnant woman suffers from stress, she's more likely to have a low birth weight baby than a non-stressed pregnant woman if both are exposed to the same toxic chemicals, according to the first study examining the combined impact of stress and environmental chemicals on fetal development.
Study of premature babies has implications for future treatment Research carried out by the University of Kent with doctors on the neonatal unit at the William Harvey Hospital and Brunel University have provided further insight into the biology of premature birth, with findings that may have implications for treating premature babies.
The way certain hospital labor and delivery units are managed may put healthy women at greater risk for cesarean deliveries and hemorrhage, according to a new study from Harvard T.H. Chan School of Public Health researchers and colleagues.
Scientists have found a single protein -- Ptbp2 -- controls a network of over 200 genes central to how developing sperm move and communicate. The protein works by regulating how RNA is processed during each stage of sperm development.

Males can produce hundreds of millions of sperm within a single ejaculate depending on the species. Does it matter then which sperm is actually fertilizing the egg? New research shows that selecting for longer-lived sperm results in offspring with better survival prospects early in life and higher quality as adults. The study by UEA, UK and Uppsala University, Sweden, could have major implications for adaptive evolution and research into assisted fertilization technologies, such as IVF.
