Is a single 0.5 ml straw a dose?
Not in the opinion of most experts. Even if the number of post-thaw sperm is 250 million or more, many of the sperm are damaged by the intense compression needed to pack enough viable sperm into a single straw. Furthermore, even if there are enough motile sperm post-thaw, there is not enough volume of seminal fluid to get it where it needs to go!
