New findings from a team of Australian scientists suggest increased exposure to testosterone during pregnancy, triggered by a vitamin D deficiency, may be one of the causal factors explaining why autism spectrum disorder is more common in boys.

A new review encompassing dozens of observational studies and meta-analyses suggests there is no safe level of caffeine consumption during pregnancy. The review calls for a “radical revision” to health recommendations but not all experts agree with the findings.

Many readers are likely already familiar with the oximeters that measure blood oxygen levels via the patient's finger. Well, scientists have now developed a device that works on the same principle, but it can be non-invasively used on unborn fetuses.

According to British scientists, a lack of stem cells in the lining of the womb is one of the main causes of recurrent miscarriages. There may be hope, however, as they also believe an existing diabetes medication could help remedy the situation.
