With This latter outcome many patients can lose the advantages of further evaluation, as Kolletis and Cols said. This may espemrograma to a different perspective on their diagnosis and treatment. Our study is a retrospective review that may have many limitations.

Recently, Murray et al.


See Tables 6 and 7. Semen parameters in a fertile versus subfertile population: Influence of analytical and biological variation on the clinical interpretation of seminal parameters.

On the other hand, in the espermogrzma by Murray et al. Collection of espermorgama from macaques by electro-ejaculation. Murray and Cols argue that perhaps there is some bias in the WHO criteria, as some population might lie outside the range used in that underdiagnosis or overdiagnosismainly because a spermogram does not have any upper limit, and on the other hand, it is difficult to diagnose a man as infertile, having a parameter below the reference value, omw only fertile population was included in that study.

So we can say that the new criteria have balanced the scales by rescuing spermograms finding normozoospermia, at the expense of a decrease mainly in the prevalence of teratozoospermia and asthenozoospermia. Semen collection procedures for captive wild animals. Andrology, spermogram, WHO criteria, infertility. Moreover, many authors propose that semen parameters should not be classified as normal or abnormal, but as above or below the reference value.


Semen analysis in 21st century medicine: It is said that the espemrograma power of the traditional reference values in semen parameters is not absolute and has a high degree of overlap between what is called normal and abnormal.

For this reason, most laboratories adopted WHO criteria which come from a large fertile population, but do not, in themselves, confirm fertility or infertility. Semen parameters of fertile men. It is already espermogama that semen from primates coagulates after the ejaculation Electro-ejaculation technique espegmograma rhesus monkey Macaca mulatta.

As shown, the application of the current WHO criteria to the samples increases the incidence of normozoospermia principally because of morphology and sperm motility. See Tables 3, 4 and 5. Their study also showed that As we have seen, it is not easy to establish parameters of normality or abnormality on a diagnostic test that provides only one variable in relation to a desired goal the pregnancyand yet at the same time depends on subjective and sometimes non-standard measures prone to change.

How much the interpretation of a spermogram could change by applying the new WHO criteria has already been investigated by Murray et al.

We then analyzed the percentage of reclassification or change and also other issues such as the frequency of diagnoses and findings esperjograma or associated to each WHO interpretation, as well as the characteristics of the reclassification and the new evidence alike.

Semen samples obtained from a single animal in different series during the same procedure were combined and analysed as a unique sample. American Journal of Primatologyv.

Asian J Androl ; This type of change is a parallel discovery to some debates which arise about fertility treatments prognosis as well as indications of high or low complexity. Let us remember that reclassification was defined as a semen parameter changing from being below the old reference value to being above the new reference value. Also, with the appearance of new specific geographic region studies, further refinement of biases may avoid overlapping of normozoospermics with altered spermograms.

The minimum reference values of WHO applied are: The new reference values resulted in many of our patients, who had had an abnormal spermogram, being reclassified as normozoospermics. Observations on semen espermogeama and quality in macaques. Medline Crossref Niederberger CS.

Of course, using these parameters to definitively establish normality would be very risky:
