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 .
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 ...
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.
Terms oligospermia, oligozoospermia, and low sperm count refer to semen with a low concentration of sperm [1] and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically oligoasthenoteratozoospermia ).
A 1992 World Health Organization report described normal human semen as having a volume of 2 mL or greater, pH of 7.2 to 8.0, sperm concentration of 20×10 6 spermatozoa/mL or more, sperm count of 40×10 6 spermatozoa per ejaculate or more, and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid ...
] This may be explained by the fact that sperm banks only accept donors who have good semen quality, and because of the rigorous screening procedures which they adopt, including a typical age limitation on sperm donors, often limiting sperm donors to the ages of 21–39 (see paternal age effect), and genetic and health screening of donors. In ...
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 ]
Sperm may occasionally be observed in the urine of both males and females; in female children and vulnerable adults, this can indicate sexual abuse. Reporting the presence of sperm in human urine (spermaturia), especially in women,is a controversial topic.
