What is the Semen Quality?
It is important to get as much information about the frozen semen as possible – have pregnancies resulted from this frozen semen, what is the pregnancy rate per cycle or per season, what is the post-thaw motility and how is that motility evaluated? What is the concentration of sperm and how many straws constitute a dose? Each dose of semen should have at least 30% post-thaw progressive motility and contain a minimum of 200 million progressively motile sperm per dose. However, semen analysis can very between clinicians. If you have any concerns about the frozen semen we recommend that you have it analyzed by an independent lab, ideally before you invest in the purchase of a lot of semen and the associated importation costs. Our SBS affiliate locations in Europe, North America and Australia can assist you with semen import and analysis.
