When performing cryopreservation of semen, it is the sperm quality after reviving the sample that is of importance, because many sperm cells die in the process.
To be of use in assisted reproductive technology, the sample should after thawing have more than 5 million motile sperm cells per ml with a good grade of mobility.
However, despite these compensations, there are activities that should not be performed too often, in order to prevent infertility due to heat; Contrary to widely held beliefs, no evidence supports that wearing constrictive underwear, or "briefs," decreases fertility.
Even with an elevation in temperature of 0.8-1° caused by wearing constrictive underwear, no changes in sperm parameters, no decrease in spermatogenesis, and no changes in sperm function are observed A blow from outside does not affect the sperm quality of already produced sperm cells.
If the grade of mobility is poor, 10 million motile cells per ml is required. It does not necessarily mean an otherwise bad semen quality.
When a sperm sample is prepared for intrauterine insemination, it is washed at a facility such as a fertility clinic or a sperm bank.Semen quality is a measure of the ability of semen to accomplish fertilization. It is the sperm in the semen that are of importance, and therefore semen quality involves both sperm quantity and quality.Decreased semen quality is a major factor of male infertility.An abstinence period of only 1 or 2 days produce the highest pregnancy rates per IUI cycle compared with longer intervals of ejaculatory abstinence.For semen that has been ejaculated, the quality deteriorates with time.For example, one study of 943,664 children less than 10 years old, No age related effects on sperm were noted in separate control groups recruited in different geographical locations, indicating that dietary habits, lifestyle or ethnicity could play a part in the quality of sperm.
