Reference values pH: 7.2 or more. sperm concentration: 15 million spermatozoa per ml or more. total sperm number: 39 million spermatozoa per ejaculate or more.
total number of PR sperms (51.61 vs. 59.63 mil/ejaculate), percentage of normal form sperms (3.70% vs. 6.00%), curvilinear velocity (36.10 vs. 48.97 μm/s), straight-line (rectilinear)
We report here the case of two brothers, both exhibiting a total absence of motile and normal spermatozoa in their ejaculates, with a very high index of multiple abnormalities (IMA) per sperm cell. Two ICSI attempts were made for one of these brothers, which were both unsuccessful....
This may result in a failure to eliminate defective spermatozoa, and thus there may be an accumulation of abnormal and healthy germ cells in the final ejaculate. The present study also shows that the rate of increase of sperm concentration with increasing age was higher in the 2000s. The ...
Evidence for infection of the seminal ducts provides the count of peroxidase-positive cells (normal <1 × 106cells per ml), elastase (normal <250 ng/ml), a positive sperm culture, or evidence of bacterial prostatitis. The importance of inflammation tests is controversial. ...
Obesity is a prominent risk factor for male infertility, and a high-fat diet is an important cause of obesity. Therefore, diet control can reduce body weight and regulate blood glucose and lipids, but it remains unclear whether it can improve male fertil

Cryopreservation may positively select spermatozoa, accelerating elimination of senescent spermatozoa by necrosis, so that early apoptotic spermatozoa from fresh ejaculate are not found in thawed samples. These results, that need to be completed by a study on a larger sample of oligospermic patients, ...
Conversely, most men exhibiting normal or minimally subnormal semen characteristics displayed declining values in their second ejaculate. There is, however, a dearth of information about the relationship between abstinence duration and various forms of semen disease. Sperm motility in IVF is positively ...
