Please keep your eggs and sperm inside the body until you are ready to use them.
See what happens when you don’t? According to this article from the UK, errors in IVF clinics have doubled in the last year. Lest you think this is some ordinary error, listen to this:

One couple were told by the University Hospital of Wales’s IVF clinic that their last remaining embryos had been lost during treatment. The pair, identified only as Clare and Gareth, had been trying for a baby for eight years. Clare told the BBC: “I was sat there, gowned up, waiting to go in and have a transfer.

“They said you’ve got one embryo remaining, the other two embryos have gone missing.

“They said in the next sentence I can assure you they haven’t gone into anyone else.”

She added: “Those were two potential babies.”

No kidding. Read the whole article here.
