A semen analysis (plural: semen analyses), also called seminogram or spermiogram, evaluates certain characteristics of a male's semen and the sperm contained therein. [ 1 ] [ 2 ] [ 3 ] It is done to help evaluate male fertility , whether for those seeking pregnancy or verifying the success of vasectomy .
Collecting the sperm at home gives a higher sperm concentration, sperm count, and motility, particularly if the sperm is collected via sexual intercourse. [35] If the semen sample is to be collected by masturbation, a specimen from the early stages of the ejaculation should be placed into a clean, unused, sealed collection cup.
To get that value, two different variables are multiplied: sperm concentration—the number of sperm per millimeter of semen—and semen volume, which is exactly what it sounds like.
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml).
A significantly lower zinc plasma concentration value within the semen was observed in infertile males. Supplementation with zinc could benefit sperm quality by increasing the semen volume and improving sperm motility and morphology. [10] Notably, no significant effects on sperm concentration, count, or sperm viability have been conclusively ...
Male genital examination is a physical examination of the genital in males to detect ailments and to assess sexual development, and is normally a component of an annual physical examination. The examination includes checking the penis , scrotum , and urethral meatus . [ 1 ]
