An international team of bioethicists and scientists, led by a researcher at Case Western Reserve University, contends it may be justified to go beyond the standing 14-day limit that restricts how long researchers can study human embryos in a dish. Going beyond this policy limit could lead to potential health and fertility benefits, and the authors provide a process for doing so.
In a new paper published by Nature Communications, The Lundquist Institute (TLI) Investigator Wei Yan, MD, PhD, and his research colleagues spell out an innovative strategy that has led to the discovery of a natural compound as a safe, effective and reversible male contraceptive agent in pre-clinical animal models. Despite tremendous efforts over the past decades, the progress in developing non-hormonal male contraceptives has been very limited.
CLEVELAND, Ohio (March 3, 2021)--The length of the female reproductive period (the time from the onset of menses to the final menstrual period) has important health implications. A new study compared the length of reproductive periods for women with type 1 diabetes with women without diabetes to confirm the effect diabetes has on the female reproductive system. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
New research has found that shrimp like creatures on the South Coast of England have 70 per cent less sperm than less polluted locations elsewhere in the world. The research also discovered that individuals living in the survey area are six times less numerous per square metre than those living in cleaner waters.
Adequate spacing between births can help to alleviate the likelihood of stunting in children, according to a new study from TCI. Sunaina Dhingra and Prabhu Pingali find that differences in height between firstborn and later-born children may be due to inadequate time between births. When children are born at least three years after their older siblings, the height gap between them disappears.
A University of Chicago Medicine researcher working with an international team of scientists has developed a daily oral combination therapy that is reliable, safe and effective for long-term treatment of uterine fibroids.
Children born as a result of fertility treatment have different growth patterns to naturally-conceived children but, by the time they reach the age of 17, they are of similar height, weight and body mass index (BMI), according to research published in Human Reproduction.
Keck Medicine of USC study shows that semen can accurately be tested up to 52 hours after being collected, offering men greater flexibility in how they provide sperm specimens
Researchers at the Centre for Genomic Regulation reveal that newly formed embryos clear dying cells to maximise their chances of survival. It is the earliest display of an innate immune response found in vertebrate animals to date. The findings may aid future efforts to understand why some embryos fail to form in the earliest stages of development, and lead to new clinical efforts in treating infertility or early miscarriages.
Researchers at Brown found that expanding access to long-acting reversible contraception methods, such as IUDs and implants, could give adolescents more agency in choosing whether and when to become pregnant again.
