Semen analysis
The male factor infertility is most commonly defined as abnormalities in the number of sperm present, proportion of the motile and morphologically normal sperm. WHO has defined normal values for human ejaculate.
Semen analysis test
Semen analysis is not a test for fertility .
- Fertility determination is a couple-related phenomenon that requires the initiation of a pregnancy.
- The patient cannot be considered fertile based only on normal semen analysis.
- It was shown that 30% of all patients with normal semen analysis have abnormal sperm function.
- Typically two to three semen analyses are obtained over a 3 month period prior to making any final conclusion regarding baseline sperm quality or quantity. However, if the first semen analysis is normal, the repeat test is not required. Recent febrile illness or exposure to gonadotoxic agents may affect spermatogenesis for up to 3 months; therefore semen analysis has to be postponed.
Semen analysis includes the examinations of:
- Spermatozoa
- Other cells present in semen
- Seminal fluid
Altogether these data give indications on the testicular function and of the integrity of the male genital tract.
Spermatozoa (sperm) are the male sex cells that carry a man's genetic material. Pregnancy occurs when a sperm penetrates a woman's egg (ovum).
