Freezing and storing embryos during fertility treatment using a technique called vitrification is safe, although women are less likely to become pregnant and have a live birth the longer the embryos are stored, according to new research published in Human Reproduction.
Differences in the rate that genetic mutations accumulate in healthy young adults could help predict remaining lifespan in both sexes and the remaining years of fertility in women, according to University of Utah Health scientists. Their study, believed to be the first of its kind, found that young adults who acquired fewer mutations over time lived about five years longer than those who acquired them more rapidly.
A study conducted by clinicians from KK Women's and Children's Hospital (KKH) and researchers at the Nanyang Technological University, Singapore (NTU), which evaluated and demonstrated the safety and effectiveness of a KKH-developed novel clinical protocol to screen and triage women with threatened miscarriages, has been published in the journal, Scientific Reports.
If you're a cat owner, you might have heard of Toxoplasma gondii, a protozoan that sometimes infects humans through contact with contaminated feces in litterboxes. Although harmless to most people, T. gondii can cause serious illness or death in immunocompromised individuals or fetuses of infected pregnant women. Now, researchers reporting in ACS Nano have studied how the microorganism glides so swiftly through mammalian tissues during an infection.
DNA from uterine cells of women with endometriosis has different chemical modifications, compared to the DNA of women who do not have the condition, according to researchers funded by the National Institutes of Health. The changes involve DNA methylation--the binding of compounds known as methyl groups to DNA--which can alter gene activity.
Transmission of COVID-19 from mother to baby during pregnancy is uncommon, and the rate of infection is no greater when the baby is born vaginally, breastfed or allowed contact with the mother, according to a new study.
The children of mothers with long-term depression have been found to be at higher risk of behavioural problems and poor development.
Scientists have developed a new model to study an early stage of human development, using human embryonic stem cells.
Using electronic health record (EHR) data to simulate drug trials for pregnant patients could one day offer a solution to the current practice of delivering babies pre-term if an expectant mother contracts COVID-19, according to a position paper published in Nature Medicine.
Human eggs use chemical signals to attract sperm. New research from Stockholm University and Manchester University NHS Foundation Trust shows that eggs use these chemical signals to "choose" sperm. Different women's eggs attract different men's sperm - and not necessarily their partners.
