I just celebrated my 35th birthday, which according to my tenuous 20-something life plan was when I would be married and about to embark upon baby making. I won’t go into the various reasons why this hasn’t happened. It’s complicated, but in one sense it’s also perfectly simple – I’ve been progressing in life, ticking some boxes, leaving others expectantly empty because, as we are constantly told, we can’t expect to have it all. And yet, biology hasn’t yet caught up with the requirements of the modern woman lifestyle. As a result, the question of “to freeze or not to freeze” increasingly crops up in conversation with my female friends. Some are single, some are in happy relationships but for a variety of reasons (financial, social, professional) they are all considering delaying motherhood for either the first or second time.
