In a nutshell Kevin, do you think:

a) the right TO have a child should always supersede the right NOT to have a child

or

b) a woman's rights regarding children always supersede a man's rights?

This about that carefully. Neither is supported by current law in the UK or US. Both could have drastic consequences. As for your example where her right take precedent, that would proclude a man having ANY rights to the zygotes -- because if her rights take precedence she could demand the child back *even after implantation.*
