But the numbers still weren't high enough, so Lipshultz recommended proXeed. Harrist has been on the drug for four and a half months, taking it twice a day, seven days a week. Harrist, however, is not a participant in the ongoing study of proXeed. He was disqualified because of his operation. Harrist's sperm quality has improved while he has been on proXeed, Lipshultz says.
Sperm quality is the subjective evaluation of how well sperm move.
It's scored on a scale from 0 to 4.0, which is considered perfect. Harrist scored a 2.0 on sperm quality before his surgery, Lipshultz says. After the surgery, Harrist's score briefly rose to 2.5, then dropped again to 2.0. After he went on proXeed, Harrist's score rose again to 2.5, Lipschultz says. Nevertheless, a man's ability to produce quality sperm can vary greatly from month to month, and also can be affected by changes in health, diet, and hormone levels, says Lipshultz.
