Women with intellectual and developmental disabilities have nearly double the rate of having another baby within a year of delivering compared to women without such disabilities, according to a new study published in CMAJ.
Men who wear boxer shorts have higher sperm concentrations than men who wear tighter fitting underwear, according to new research published in Human Reproduction. The study differs from previous research on this topic because it includes a larger number of men (656) than previous studies, and because it is the first to go beyond the traditional, narrow focus on semen quality and include information on a variety of indicators of testicular function, such as reproductive hormones and sperm DNA damage.
Men who most frequently wore boxers had significantly higher sperm concentrations and total sperm counts when compared with men who did not usually wear boxers, according to new research led by Harvard T.H. Chan School of Public Health.
In countries which already permit embryo research, there are no 'compelling moral arguments' why the time limit for experimentation should not be doubled say ethics experts. This could enable synthetic embryos in the lab which can grow into humans, improved IVF treatment, the creation of 'organoid' models of human organs for replacement and research to allow infertile/same sex couples to have genetically related children.
The genetic screening of fertilized eggs for embryo selection in assisted reproduction makes no difference to live birth rates, according to results from the largest published study of its kind. Results from this multicenter randomized controlled trial are reported today in the journal Human Reproduction and, say the authors, confirm the 'widely accepted' view that preimplantation genetic testing for chromosome abnormality (PGT-A) will not increase live birth rates in IVF.
Pregnant women who had low plasma levels of long chain n-3 fatty acids in their first and second trimesters were at a significantly higher risk of early preterm birth when compared with women who had higher levels of these fatty acids, according to new research from Harvard T.H. Chan School of Public Health in collaboration with Statens Serum Institut in Copenhagen
Fruit flies have a rich language of smell messages that they exchange, but now their secret is out. In a report published Aug. 2 in Current Biology, scientists were able to tap into the communications among freely interacting flies using a bioluminescent technology to monitor their brain activity. They discovered that males signal their presence by placing droppings that act as a calling card for flies to find each other and even lure females to designated locations.
In new research published Aug. 2 in the journal PLOS Genetics, UW-Madison researchers discovered that two genes work together to construct a cellular communication system in the ovaries of mice to maintain healthy eggs.
Refined mentorship programs, further education and understanding are cited as necessary to improve work-life balance
Women who take epilepsy drugs while they are pregnant may have a lower risk of having a child with delays in language skills if they take folic acid supplements before and early in pregnancy, according to a study published in the Aug. 1, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
