Post thaw percentages

Postby Ponywoman1 » Sat Mar 16, 2013 10:36 am

What is the usual range of post thaw semen motility? What is ideal?

Thank you for your help!

The range would be the same as for cooled semen, or perhaps slightly lower at the upper end.

One has to be careful with the concept of "ideal motility" with frozen semen, as one can have excellent motility and no fertility, or vice versa. While one would like to see >30% progressive, that does not indicate that it will be fertile.

Motility as a whole is somewhat misleading, as one frequently hears "the semen we got was poor motility" - referencing either cooled or frozen - but in actual fact, the number of sperm that are motile is more important than the motility itself - and again we have to add the caveat that one can have good motility but zero fertility (this happens with cooled as well, but less commonly).
We're always happy to try and help, but don't forget to check the articles section
of the website too, which has a search engine to help you look for answers!
