I felt that we learned a lot at the Rainbow Families conference last weekend. Among the most interesting or important things follow, as well as the answer to at least one of my burning questions:
Yes, mainly due to the fact that freezing techniques have changed in the past however many years. Thus, using 1 year old frozen sperm vs. 3 year old frozen sperm will probably not matter, but using sperm frozen in the early 90’s vs. the early 2000’s may actually matter. One of the donors Nutella and I were looking at (but crossed out) had donated in the 1980’s! I’m extra glad now that we’re not using those swimmers.
The good thing about washing sperm is that it weeds out all of the dead or weak swimmers, as well as all the other yucky stuff that you don’t need. What you’re left with is a highly concentrated ‘packet’ of good, strong swimmers which are then deposited directly into the uterus when using IUI. Do NOT, repeat, Do NOT eject ICI/unwashed sperm directly into the uterus. This sperm is not supposed to go directly there and will cause uterine contractions that can be severe. The doctor even mentioned that this has been known to cause death.
If anyone reading wants to add anything or had different experience with those issues, please let us know 🙂
