How to socialize unneutered female and male rabbit, before or after neutering?

Question

Situation:

We own an unneutered female rabbit, since one week she is alone because her partner died. The search for a new partner is difficult, because we want an adult neutered rabbit-man for her, dwarf, no teddy fur and no lop ears. We have found one male rabbit, but he is unneutered. (Searched in animal shelters and small ad)

Aim:

We want to exclude the cause, that they absolute dislike each other, before we neuter the male. But we do not want the female to become pregnant.

Question(s)

Is there the chance to do so?

Can neutering change something, so it works before, but not after it?

How big is the risk, they see and at once start to mate?

Background

The actual owner of the male would take him back, if the socializing do not work well. I assume neutering is not part of this. Additional I want to spare the male the neutering, if we can not keep him with our female.

Answer 1

Do not put the female and male together, see this answer for more detail when the male mounts the female she will release eggs, and get pregnant. The chance of this are very high, near 100%

There are hormone changes after the surgery, it is best to wait 30 days after the surgery before introducing the rabbits to each other.

The hormone change with spay/neuter can be significant, that any meetings prior to the surgery do not provide a good gauge, for future meeting.

On occasion, brother and sister rabbits who have always lived together will start fighting and need to be separated permanently after spay/neuter.
