Oocytes mature differently in older women, in a process that could contribute to a decrease in fertility, a study from scientists in Barcelona, Spain has shown.
Scientists found that the activity of genes involved in chromosome segregation increased in oocytes progressively with age, while the activity of genes involved in mitochondrial metabolism decreased. Chromosome segregation is needed for cells to divide and multiply, and for RNA processing, while mitochondrial metabolism is essential for cell survival as mitochondria generate the energy needed for all cellular processes.
Early embryonic germ cells, which fail to develop into sperm cells, may later become testicular cancer cells, a study in mice has shown.
During embryonic development, germ cells in the embryo have the ability to develop into any cell type, a state known as pluripotency. However, these cells should develop into either sperm cells or egg cells during sex determination. Researchers at the Baylor Institute of Medicine, Houston, Texas have demonstrated that errors in this process can lead to pluripotency carrying on into puberty, allowing some of these cells to become cancerous.
Breast cancer susceptibility genes (BRCA1 and BRCA2) influence the length of some women's fertile period, according to a global meta-analysis.
There have been conflicting results from studies of how BRCA mutations influence anti-Müllerian hormone (AMH) levels, which is used as an indicator of egg reserves. While some have found that the BRCA1 mutation lower AMH levels, others have failed to reproduce this. Now, an international group of scientists including some from Yale School of Medicine, Connecticut, report that BRCA1 but not BRCA2 mutations reduce AMH levels.
Why is it important for men to undergo check-ups of their semen? Because nowadays 1 in 6 couples have fertility issues. And more than 4.000 IVF clinics worldwide agree on the fact that male infertility constitutes up to 50% of the infertility cases.
Microptic, a leading company in the field of semen analysis, has developed a new product in the current context in which sperm analysis is a more common lab test with an increasing demand: SCA SCOPE, the first totally automated lab equipment for human semen assessment.
The SCA SCOPE is an all-in-one device, linking up software with hardware of the best quality, that allows to work in optimal conditions. This equipment is smart and multi-patient, and it can be connected to a Laboratory Information System to improve traceability. In addition, the system is easy to use and capable of performing a spermiocytogram in less than 4 minutes.
