For those who are interested, here (http://susiebright.blogs.com/susie_brights_journal_/2006/06/egg_sex.html) is the link to the same article from her own blog. She also has the category 'pregnancy' (http://susiebright.blogs.com/susie_brights_journal_/pregnancy/index.html) which will probably have other relevant stuff, although a lot of the entries are about Plan B etc.

Her journal is absolutely worth spending hours wandering through, and reading regularly.
