That entirely depends on the jurisdiction - a similar case went to court in the UK back in 2000 - 2007 and the man won his case.
The woman appealed all the way to the European Court of Human Rights and lost her case completely.
The issue is that the man withdrew his permission for the embryos to be used - up to the point at which they are implanted in the woman, they are jointly owned and cannot be used without express permission of both parties. Embryos are also not legal entities, and as they are not yet part of the womans body, she does not get automatic final say over their use.

Would your argument work for you if the man was able to take the fertilized eggs and have them implanted in a surrogate who brings them to term? Surely the woman should have some say in that?
