In women with a history of miscarriage, higher levels of physical activity were associated with a greater risk of subclinical, or very early, pregnancy loss, according to new research at the University of Massachusetts Amherst. Among women with confirmed pregnancy, physical activity and miscarriage risk were unrelated.
One in three women in Europe inherited the receptor for progesterone from Neandertals -- a gene variant associated with increased fertility, fewer bleedings during early pregnancy and fewer miscarriages. This is according to a study published in Molecular Biology and Evolution by researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden.
When University of Ottawa biologists Kim Mitchell and Vance Trudeau began studying the effects of gene mutations in zebrafish, they uncovered new functions that regulate how males and females interact while mating. They changed the secretogranin-2 genes through specific mutation and found that it affected the ability of females and males to breed. It severely reduced their sexual behaviour.
A Monash University study has uncovered the role DNA repair plays in preserving egg quality, offering hope for women whose eggs may be damaged through treatments such as radiation and chemotherapy.
Center for BrainHealth published findings underscoring differences between men and women's craving or desire to consume cannabis when exposed to a specific situation. Examining differences in neural and subjective craving responses, and measuring the relative contributions of each as it relates to heavy cannabis use, they found that neural activity primarily underlies response to cannabis cues with no differences between male and female users. This is followed by subjective craving, where there are sex-related differences.
Disadvantaged and marginalized people face worsening health inequalities as a result of the difficult choices made by NHS hospitals in response to the COVID-19 pandemic. Public health doctors, writing in the Journal of the Royal Society of Medicine, say that the restriction of non-urgent clinical services, such as gynecology, sexual health and pediatrics, and the precipitous decline in emergency department attendances, will affect marginalized groups, disproportionately.
A woman's genetic make-up may cause her to gain weight when using a popular form of birth control, according to a study from researchers at the University of Colorado Anschutz Medical Campus.
Treatment guidelines for hypertension in pregnancy suggest that more women should be on medication to control their blood pressure. However, new research led by the Center for Health Evaluation and Outcome Sciences (CHÉOS) suggests that a one-size-fits-all approach doesn't work when it comes to women's treatment decisions during pregnancy.
An international consortium of researchers have identified particular sources of prenatal stress, as experienced by mothers, that have a direct effect on a child's subsequent mental health.
Tel Aviv University (TAU) researchers have developed a safe and accurate 3D imaging method to identify sperm cells moving at a high speed. The new method has the potential to significantly improve IVF treatments.
