We last spoke with Donna J Drucker about her book on the history of contraception and now her new book tackles the history of fertility and it is equally fascinating.  We get into the details of the history of conception (and the history of trying to improve conception) and so much more.

For more information, you can follow Dr Drucker on Twitter.

Meanwhile, Heidi is left trying to figure out what to wear for an 80's themed party.
