Ejaculated sperm has been shown to be significantly damaged by prolonged exposure to a WiFi connected laptop. A study, published in the journal Fertility and Sterility, found that after four hours of exposure there was a significant decrease in sperm motility and an increase in sperm DNA fragmentation.
Researchers at Oxford University have developed a test that may help to improve IVF success rates by checking the health of embryos.
The team, led by Dr Dagan Wells, has apparently developed a test which checks embryos during IVF for abnormal numbers of chromosomes. They tested a few cells taken from early human embryos, each of which should contain 23 pairs of chromosomes. With more or less than this, embryos can fail to develop normally.
For the first time, a study in humans suggests that a controversial, estrogen-like chemical in plastic may be related to conditions that reduce men's fertility.
Men with higher levels of BPA, or bisphenol A, were two to four times more likely than others to have problems with sperm quality and quantity, the study shows.

March is National Endometriosis Awareness Month, so it's time to increase your knowledge about a disease that can cause debilitating pain and is estimated to affect 6.3 million women in the United States.
Women undergoing in-vitro fertilization should have only one or two embryos transferred during the process, depending on their age, says a study published Wednesday in the British medical journal The Lancet. Transferring three or more embryos during any IVF cycle should be avoided when possible, researchers say.
Many women do not fully appreciate the consequences of delaying motherhood, and expect that assisted reproductive technologies can reverse their aged ovarian function, Yale researchers reported in a study published in a recent issue of Fertility and Sterility.
