The Lancet, 1973
The letter writers remark upon the discord among clinicians and pathologists shown by the correspondence in this journal following the writers suggestion (March 24 p.663) that semen-counts may be unnecessary provided 20 ejaculations have occurred after an effective vasectomy procedure.

Personality, coping and sperm count
Andrologia, 2005Previous research has suggested an association between personality traits and coping, as well as between coping and sperm concentration. In the present study, both domains of research were combined, leading to the formulation of specific hypotheses. A total of 54 healthy volunteers were given questionnaires twice to assess personality traits and coping

Reexamination of “normal” sperm count
Urology, 1974A males ejaculated semen can vary up to 40% in volume sperm count and sperm motivility 100 vasectomized men were studied before vasectomy for sperm counts of single specimens; 15% of these men (all fathers of 2 or more children) had sperm counts considered by accepted standards to be infertile (below 60 million).

Selection of the best ejaculate from the donor species depends greatly on precise calculation of the concentration of the live sperm cells. Different laboratories engaged in the semen biology work employ variety of instruments and procedures. These, coupled with the variability of the result induced by the objective assessment (inter-technician ...

Worldwide variations in sperm counts
Urology, 1996Based on the premise that various human disease processes manifest differently depending on geography, we set out to determine whether sperm counts vary from different nations and different regions within the United States.We reviewed the literature of all significant population-based studies that evaluated sperm counts from fertile or presumably ...
