Researchers Warn of Rapid Decline in Quality of Israeli Sperm
A recent study at Jerusalem's Hadassah University Hospital, Mt. Scopus has confirmed the findings of previous research indicating a sharp decline in the quality of semen provided by Israeli sperm donors. Researchers analyzed 2,182 semen samples that were provided on a weekly basis by 58 healthy, fertile, university-educated, paid donors aged 20 to 37 between 1995 and 2009 for motility and for total sperm count. Over the period of the study, sperm parameters declined 36 percent, from an average of 106 million sperm/ml of ejaculate in 1995 to 68 million/ml in 2009. Motility declined from 79 percent to 66 percent over the study period.
