A Michigan State University study has found that too much of a hormone commonly used during in vitro fertility, or IVF, treatments actually decreases a woman's chances of having a baby. The research, recently published in the journal Fertility and Sterility, is the largest study to analyze more than 650,000 IVF cycles in women nationwide. James Ireland, an MSU professor … [Read more...]

Before women even become pregnant, their biological profile may predict a lower-birthweight baby, a UCLA-led research team reports. Most people have a high level of cortisol -- a hormone the body releases in response to stressful events (and also at other times) -- when they get out of bed in the morning, and that level declines throughout the day. In some people, however, … [Read more...]

Breastfeeding is healthy for baby and for Mom. It has a positive impact on childhood obesity, infections and allergies, is linked to a lower likelihood of mothers getting ovarian or breast cancers later in life and to a more positive maternal-child relationship.
