sperm count

Urology A measure of the concentration of sperm in semen Normal ±100 million/mL. See Post-vasectomy sperm count, Semen analysis.

sperm count

A method of determining the concentration of SPERMATOZOA in a semen sample of known dilution. Counts are done on a slide engraved with squares of known size, using a microscope. Fertility is unlikely if the count is below 20,000,000 per ml.


a numerical computation or indication.

differential count
a count, on a stained blood smear, of the proportion of different types of leukocytes (or other cells), previously expressed in percentages but now usually reported in absolute numbers (109/l) for a better indication of abnormalities that may exist.
milk cell count
platelet count
the count of the total number of platelets per liter (109/l) of blood by counting the platelets in a counting chamber, a hematology analyzer, or by estimating the number on a stained blood smear.
sperm count
see semen concentration.
total bacterial count
determination of the total number of bacteria in the sample examined microscopically, then a calculation of the number per ml. These do not distinguish between viable and non-viable organisms. See also breed's direct smear method.
viable bacterial cell count
enumerating the number of viable bacteria present in a sample based on counting the number of colonies from a given dilution.
wool count
an arbitrary number given to wool to indicate its fiber diameter, e.g. 60's, based on an eyeball assessment of the number of hanks of yarn that could be spun from one pound of wool. Now superseded by measurement of the diameter, e.g. 20 microns.
worm count
a total worm count requires a freshly slaughtered cadaver, collection of intestinal or other fluid in an aliquot sample; in the case of lungs it is necessary to digest the tissue; counting actual worms and by multiplication measuring the total worm burden.

Patient discussion about sperm count

Q. how do i teat my no sperm count? i do not have a live sperm,how can i treat and have live sperm count

A. The treatment is done only at specialist centers, and consists first of evaluation of the reason for this condition (called azoospermia). If an anatomical malformation is found, it may be corrected, as well as medical conditions, and in some cases, direct extraction of sperms from the testes (called MESA) enables in-vitro fertilization.

Pacey believes the study results should be treated with caution, despite the recent study has reduced the possibility of errors in understanding the decline of sperm count in men.
It suggests that sperm counts have fallen by more than half in Western countries and the decline is real and not due to confounding factors such as different methods of measuring sperm numbers or population changes.
In the study, researchers pointed out that decline in sperm count has been previously linked to environmental and lifestyle influences, including prenatal chemical exposure, adult pesticide exposure, smoking, stress and obesity.
