semenianalyysi

Semenanalyysi, also known as a semen analysis or sperm count test, is a laboratory test performed on a semen sample to evaluate the fertility of a male. It is a crucial diagnostic tool used by fertility specialists to identify potential causes of infertility and monitor the effectiveness of fertility treatments.

The analysis typically assesses several key parameters of the semen. Volume refers to the amount of ejaculate produced. Liquefaction time measures how long it takes for the semen to change from a gel-like state to a liquid form. Viscosity is also evaluated. The sperm count, or concentration, indicates the number of sperm per milliliter of semen. Motility, a critical factor in fertility, assesses the percentage of sperm that are moving and the quality of their movement. Morphology examines the shape and structure of the sperm, looking for abnormalities. Vitality, the percentage of live sperm, may also be determined. Other tests can include checking for the presence of white blood cells, which might indicate infection, and assessing the semen's pH level.

A semen analysis is usually performed after a period of abstinence, typically 2 to 5 days, to ensure optimal results. Multiple samples may be required to confirm findings, as sperm parameters can fluctuate. Abnormal results can point to various issues, including hormonal imbalances, infections, genetic factors, or problems with sperm production, transport, or function. It is an essential step in the workup for couples experiencing difficulties conceiving.
