A Semen Analysis evaluates certain characteristics of a man’s semen and the sperm contained therein.
The test is done as part of a couple’s infertility investigation or to verify the success of a vasectomy. It involves a combination of procedures to assess the semen quantitatively such as sperm concentration and qualitatively such as morphology, motility and vitality.
Although this is a standard test, the diagnostic sensitivity is low and male factor infertility is frequently undetected. Approximately 15% of men with proven male factor infertility are found to have normal spermiograms.
Accordingly, additional tests can be carried out to assess the functionality of the spermatozoa. Among them, the tests for the hyaluronan-binding ability (HBA), sperm DNA fragmentation (Halosperm), and sperm oxidative stress assay are simple and quick enough that the same semen sample tested can be used for the insemination of oocytes.
