Investigating Infertility

Human ovum (c) Gray's Anatomy of the Human Body

This week, we investigate infertility and In-Vitro Fertilization (IVF). We find out how a new high resolution temperature monitor conceived in Cambridge can help couples get pregnant, and explore new ways to improve the success of fertility treatment. Plus, a new extra-fast and super-cheap way to sequence the human genome, the science of eating slowly, and fish dining out at the Shark Cafe. Also, we find out how newborns cry with an accent and examine the inner workings of an egg...

    Make a bizzare, shelless, raw egg in this easy experiment.

  • 49:55 - Can temperature change the sex of an embryo?

    It was said that women’s temperature can rise between 1.3 and 1.5 degrees. Crocodiles use temperature to regulate whether their eggs turn into males or females. So is it known whether women’s temperature altering, in some way, can affect the outcome of her babies in the same wa...

  • 50:33 - How does monitoring temperature in the 21st century differ to methods of the 80s?

    I was having problems conceiving in 1980. Before I got up every morning, I had to take my temperature. It was a very simple method. How does that really differ from this new technology which seems similar but a bit more complicated?

  • 51:52 - How fast do sperm swim and how do they find the egg?

    How fast do sperm swim? And: How do they actually track down an egg? They’re doing the equivalent of flying from Earth to the Moon, and they’re blind. And they’ve got no rocket to do it in. So how do they know where to go?”
