I have been saying this for years, people:
The quality of Israeli sperm has declined alarmingly in the last decade, according to recent research conducted at Jerusalem’s Hadassah University Hospital, Mount Scopus. 
The cause for the decline is not known, but it’s believed by some researchers to be connected to the exposure of children and pregnant women to hormones and other contaminants in food and water.
Conducted by Dr. Ronit Haimov-Kokhman, the study showed a 40-percent decline in the concentration of sperm cells among the country’s sperm donors from 2004 to 2008, compared to those of donors from 1995 to 1999. Hadassah’s sperm bank is now turning away two-thirds of potential donors because of low-quality sperm, as opposed to one-third in the past.
Emphasis mine.
Funny. Hadassah hospital and I have similar standards for men.
