How human eggs end up with the wrong number of chromosomes
One day before ovulation, human oocytes begin to divide into what will become mature eggs. Ideally, eggs are packaged with a complete set of 23 chromosomes, but the process is prone to error, especially with age. In a Review in Trends in Cell Biology, researchers discuss the latest research on why many human oocytes frequently have a wrong number of chromosomes -- which may lead to genetic disorders, such as Down syndrome and miscarriage.

Male sex hormones, such as testosterone, have well defined roles in male reproduction and prostate cancer. What may surprise many is that they also play an important role in female fertility. A new study finds that the presence and activity of male sex hormones in the ovaries helps regulate female fertility, likely by controlling follicle growth and development and preventing deterioration of follicles that contain growing eggs.

Conservation research on lynx
Scientists at the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Leibniz Institute for Molecular Pharmacology (Leibniz-FMP) discovered that selected anti-oxidative enzymes, especially the enzyme superoxide dismutase (SOD2), may play an important role to maintain the unusual longevity of the corpus luteum in lynxes. It is highly likely that SOD2 not only detoxifies the reactive oxygen radicals in the cells, but also inhibits programmed cell death. (2020-04-23)
