I'm not sure exactly what you mean either.

I know people suggest getting the donor, or partner in the case of straight couples, to ejaculate a few days before and then not again until the day of insemination just to let the sperm build up (not exactly sure of the reason, but I think its because of quality or quantity), and then inseminate a few times before, during and after ovulation as sperm can live for up to five days once inseminated. But I think they say not TOO much because if the donor is ejaculating a lot then quality (or quantity, like I said I'm not really sure of the reason) goes down.

If you mean keeping the ejaculate for more than a few hours outside of the body then that's just not possible unless you freeze it. But if you mean getting the donor to ejaculate four days before ovulation, and then again two days before and inseminate, on the day of ovulation and then insemiante, and two days after and then inseminate then I think thats a really good plan.

Hope you are pregnant too.
