The study also discovered that socioeconomic status was associated with preconception stress and blood glucose levels.
A new study published in the Journal of the Endocrine Society found that stressed women undergoing fertility treatment may experience higher blood sugar levels during pregnancy, which can lead to weaker cardiovascular health. Women who conceived through intrauterine insemination (IUI) had higher stress and blood sugar levels than those...
