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 motility. If the grade of mobility is poor, 10 million motile cells per ml is required.[8]
Home insemination of previously frozen sperm can be accomplished with the use of a cervical cap conception device as a delivery system for the sperm.[9]
Bad freezers
In 10–20% of all men, the semen doesn't endure cryopreservation.[8] The cause is unknown. It does not necessarily mean an otherwise bad semen quality.
Sperm washing
When a sperm sample is prepared for intrauterine insemination, it is washed at a facility such as a fertility clinic or a sperm bank. Some sperm does not survive the washing process, as is also the case when freezing the sperm.[10]
