sperm count

The number of sperm/mL in semen. The lower reference limit (2.5th  percentile) is 39 million sperm per ejaculate.

sperm count

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.

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.

To test for patterns of compatibility independent of spine color in the single-male trials, an ANCOVA, with the response variable being the arcsine-transformed proportion of eggs fertilized, examined the main effects of male identity, female identity, and their interaction with the covariates of sperm concentration and the polynomial of sperm concentration, to account for the non-linearity caused by polyspermy, and the interactions between these covariates and the main effects.
They also found that TCS was negatively associated with sperm concentration, sperm count, the number of forward moving sperms, and the percentage share and the number of morphologically normal sperms but only in the lowest tertile of urinary TCS concentration (< 0.66 ng/mg).
