Lifestyle changes such as maintaining regular sleep patterns, a healthy BMI, and stress management may help alleviate symptoms.
Researchers at Harvard University developed a Human Vagina Chip to study the effects of microbiome on vaginal health. The chip replicated the human vaginal tissue microenvironment, including its microbiome, and showed that certain strains of bacteria can help maintain an acidic environment and reduce inflammation.
Researchers developed a nanoparticle-based approach that uses photoacoustic imaging and infrared light to detect and potentially treat ectopic pregnancies. The technology shows promise in mice studies and may offer a non-invasive and effective way to improve diagnosis and treatment of the condition.
A new study finds that COVID-19 orphanhood is significantly higher in poorer countries due to pre-existing health and vaccine coverage inequity. The risk is driven by factors like poverty prevalence, lower GDP per capita, and non-communicable diseases.
A new study found that women with obesity have suppressed ovarian follicle development and reduced production of reproductive hormones, which may underlie reduced fertility. The researchers also discovered that luteal phase defects are more prevalent in obese women during natural ovulatory cycles.
Researchers have identified the Xist gene as a critical regulator of fetal development in mice, leading to miscarriage and abnormal placentas when epigenetic instructions are missing. The study's findings suggest that failed Xist imprinting can be 'cured' by targeting specific genes involved in histone modifications.
Researchers have found that the meningococcal B vaccine is 33% effective against gonorrhoea in adolescents and young adults. The study aims to reduce not only gonorrhoea infection but also its long-term effects, such as infertility and blindness in babies born to infected mothers.
A recent study published in The Journal of Urology found that serum hormone ratios can predict the risk of future infertility in children with cryptorchidism. Researchers discovered that inhibin B levels and anti-Mullerian hormone (AMH) are significant markers of spermatogenesis, helping to identify boys at high risk of infertility.
Scientists at the University of Missouri discovered that bisphenol A (BPA) exposure during pregnancy can negatively impact fetal brain development. MicroRNAs in the placenta play a key role in regulating cellular functions, including neural development. Researchers believe that microRNA packages could reach the brain through the placen...
Researchers found high levels of per- and polyfluorinated alkyl substances (PFAS) in anti-fogging sprays and cloths sold on Amazon. The products contained fluorotelomer alcohols and fluorotelomer ethoxylates, which are associated with impaired immune function, cancer, and other health disorders. The study highlights the need for more r...
A new study reveals that poor women in rural India are more likely to die during childbirth due to lack of access to safe hospital births. The research found that only 26% of women in low-performing states deliver in hospitals, compared to 87% of those exposed to mass media.
A large observational study found that children conceived through assisted reproductive techniques (ART) have generally good mental health throughout adolescence and young adulthood. However, those born after ART had a slightly elevated risk of obsessive-compulsive disorder, which was explained by parental background factors.
A study led by Children's Hospital of Philadelphia researchers used stem cells to implicate several genes involved in bodily functions associated with the hypothalamus. The findings could help clinicians identify potential causes of dysfunction for traits regulated by the hypothalamus, such as sleep and stress.
Research suggests COVID-19 pandemic has adverse effects on women's menstrual cycles due to stress and sleep disturbance. Women are experiencing increased rates of depression, anxiety, and poor sleep.
