Fertility News from ScienceDaily.com

  1. A phthalate found in many plastic and personal care products may decrease fertility in female mice, a new study found. Researchers found that giving female mice oral doses of the phthalate DiNP for 10 days disrupted their estrus cycles, decreasing their ability to become pregnant for up to nine months afterward.
  2. While previous studies have shown the adverse health effects of prenatal exposure to the industrial chemical bisphenol A (BPA), there is little evidence surrounding effects specifically on ovarian function. A new study now finds there is sufficient data to raise concerns regarding exposure and ovarian performance.
  3. Research shows that sperm that live for longer before fertilizing an egg produce healthier offspring. What's more, these offspring go on to have longer, healthier lifespans -- and in turn produce more and healthier offspring themselves. It was assumed that it doesn't matter which sperm fertilizes an egg. But this shows that there are massive differences between sperm and how they affect offspring. The research was carried out in zebrafish but may have implications for human fertility.
  4. From fathers to children, the delivery of hereditary information requires the careful packing of DNA in sperm. But just how nature packages this DNA to prepare offspring isn't clear. Using new technology to reveal the 3D organization of DNA in maturing male reproductive cells, scientists revealed a crucial period in development that helps explain how fathers pass on genetic information to future generations.
  5. Researchers have developed new robotic sensor technology that has the capability to diagnose women's reproductive health problems in real-time.
