A study found that young women with heart disease experience worsening exercise performance and angina pain in the early follicular phase, just after menstruation, but improved performance and slower pain onset in mid-cycle. Sex hormones may play a role in these fluctuations.
A University at Buffalo study found that a woman's biology, specifically age at first menstruation and first live birth, are major predictors of resolved fertility in fertile women, not lifestyle habits. Women over 30 at first live birth were three times more likely to take longer than a year to conceive.
Research suggests that women under 50 may experience false-negative mammogram results when screened during the luteal phase of their menstrual cycle. By scheduling mammograms during the first half of their cycle, the accuracy of breast cancer detection can be improved.
