There is a growing appreciation and understanding of cell-to-cell variability in biological samples. However, research and clinical practice in male fertility has relied on population, or sample-based characteristics. Single-cell resolution is particularly important given the winner-takes-all nature of both natural and in vitro fertilization: it is the properties of a single cell, not the population, that are passed to the next generation.

February 6, When potential DNA evidence—say, from a sexual assault case—is submitted to a forensic lab for analysis, the scientists are often faced with the time-consuming challenge of sorting out which DNA profile came from the victim and which came from the criminal. A new process being developed by VCU forensic science and physics researchers might make the process easier.

Scientists have devised a way to separate the strongest sperm from the rest of the pack in a development that could improve the success rates and speed of IVF. Whether a fertility specialist uses one or several sperm to try to fertilize an egg, the stronger these sex cells are, the better the odds that they will successfully fertilize the egg and that the resulting embryo will implant and grow. A tiny horseshoe-shaped corral traps the strong-swimming sperm that a drawn to go upstream by a retraining wall, helping scientists gather only the highest quality sperm for IVF.

Ross Clark. It is hard to think of a code of behaviour which is common to all societies on earth, let alone to most other species too — except, that is, for the avoidance of incest. Even cockroaches have developed a breeding strategy that prevents them mating with their own siblings.

When implanted in the uterus of mice, the beads proved to be effective sperm traps, preventing pregnancy. They serve a dual purpose, as they could also be used to select the healthiest sperm for infertility treatments. To design these special sticky beads, scientists started with agarose beads —large carbohydrates extracted from seaweed used in laboratory testing—and coated them with the same peptide responsible for binding sperm to eggs, known as ZP2, or zona pellucida glycoprotein 2.

Can flagellar analyses be scaled up to provide automated tracking of motile sperm, and does knowledge of the flagellar waveform provide new insight not provided by routine head tracking? High-throughput flagellar waveform tracking and analysis enable measurement of experimentally intractable quantities such as energy dissipation, disturbance of the surrounding medium and viscous stresses, which are not possible by tracking the sperm head alone. The clinical gold standard for sperm motility analysis comprises a manual analysis by a trained professional, with existing automated sperm diagnostics [computer-aided sperm analysis CASA ] relying on tracking the sperm head and extrapolating measures.

A new sperm-sorting device built at Stanford filters the unfit from the fit and could help improve infertility treatments. The unshapely sperm are diverted by the pillars in the device and don't emerge from the filtering system. A device the size of your business card can separate the strong, healthy sperm cells from the duds, and it does so in about 10 minutes, according to a new study led by researchers at the Stanford University School of Medicine and the Worcester Polytechnic Institute. It filters semen through rows and rows of pillars fitted for healthy sperm.
