In recent years, there has been much discussion about the low Jewish birth rate. In fact, Jews are dying off faster than they are being reborn. Haaretz reports on a new wrinkle in Jewish reproduction. The quality of Jewish sperm has deteriorated rapidly and dramatically in the past decade, and simply switching to boxer shorts might not be enough.
More based on research from Jerusalem’s Hadassah University Hospital, Mount Scopus:
The research confirmed that in 10 years, the average concentration of sperm among donors declined from 106 million cells per cubic centimeter to 67 million per cubic centimeter. The rate of sperm motility has also declined: from 79 to 67 percent, although the profile of donors did not change over that period; they are still young, healthy and do not smoke.
According to Haimov-Kokhman, the quality of sperm has declined in most Western countries, but in Israel it has been particularly rapid.
“If we keep going at this rate, a decline of 3 million cubic centimeters of sperm cells per year, we’ll reach an average of 20 million in 2030. The World Heath Organization defines this as fertility impairment.”
