Property and Procreation: Problematising Sperm

Recently in the US, bills have been sponsored in a number of states providing for personhood for sperm.  One bill, for example, provided that ejaculating anywhere outside a woman's vagina constitutes 'an action against an unborn child'.  These bills were put up in response to legislation regulating women's reproductive rights - curtailing women's access to contraceptives and abortion.

The law in the US (and elsewhere) continues to regulate the reproductive rights of women with wide acceptance that this is appropriate.  In contrast, the 'sperm bills' are considered satirical.  It's OK to regulate women's reproductive rights, but patently ridiculous to regulate men's.

This shows that reproductive rights and regulation of gametes is obviously a complex issue for the law. (See my previous post here)

This complexity is borne out through a comparison of a recent Canadian decision (JCM v ANA), a forthcoming Canadian case (deBlois), and a 2011 Australian decision (Edwards). (I've written about this case here.)  To what extent does the law recognise rights to sperm, in terms of property; procreation; and parenting?
