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.
A breakthrough IVF method has been developed to significantly improve in-vitro fertilization (IVF) in cattle, reducing pregnancy issues and increasing overall meat and milk production. The new process improves live birth rates with a high accuracy rate, offering vast potential for the cattle breeding industry.
Belgian researchers have developed an all-in-one test to identify healthy embryos for transfer, reducing the risk of passing de novo genetic diseases. The test uses long read sequencing and can detect copy number variants and single nucleotide variants in a single workflow.
A new study found that female offspring of women with polycystic ovary syndrome have an increased risk for developing cardiac dysfunction. Researchers linked maternal androgen excess and continuous exposure to male hormones during fetal life as contributing factors.
A Chinese family with GJB2-associated hearing loss underwent an integrated reproductive strategy combining preimplantation genetic diagnosis and noninvasive prenatal testing. The approach resulted in a healthy baby, demonstrating its potential to prevent hereditary hearing loss globally.
Women with systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS) are at increased risk of reduced fertility and pregnancy complications. EULAR's new recommendations provide guidance on supporting family planning, assisted reproduction, and healthy pregnancy in these patients.
Families whose first child was diagnosed with autism spectrum disorder had lower birth rates compared to control families. Women who changed partners also experienced a stronger reduction in reproductive behavior.
A unique study highlights the importance of universal newborn screening for congenital adrenal hyperplasia (CAH), a life-threatening disorder affecting cortisol production. Screening improves survival in both boys and girls, contradicting previous beliefs that boys were at higher risk of delayed diagnosis.
A WSU study found that dioxin exposure to pregnant rats resulted in reproductive problems and disease in subsequent generations, including prostate disease and ovarian disease. The effects can be passed down to great-grandchildren, highlighting the potential long-term impact of environmental toxins on health.
Researchers have developed a new technology that allows for an individualized map of the DNA within a single sperm cell, providing insights into genetic diversity and potential applications in reproductive disorders. This technology could also be used to characterize differences in cancer cells taken from patients.
A study published in International Journal of Andrology reveals a significant difference in environmental chemicals found in breast milk between Denmark and Finland. High levels of EDCs were associated with male reproductive problems, including testicular cancer, in Denmark, while Finland had lower exposure levels.
A recent study by the European Society of Human Reproduction and Embryology found that while Beckwith-Widermann syndrome had a significant risk for children conceived through ART, no significantly higher rates of other disorders were observed in children born after ART apart from BWS. The researchers also identified a possible mechanis...
Research finds a correlation between disrupted spermatogenesis and abnormal genomic imprinting in men with low sperm counts. The study suggests that spermatozoa from oligozoospermic patients carry an increased risk of transmitting imprinting errors.
A study published in Cancer Research reveals that a gene called RhoC GTPase contributes to the development of an aggressive and deadly form of breast cancer. The research found that overexpression of this gene in normal cells leads to rapid tumor growth, invasion, and metastasis.
