You've probably heard of gut microbiome, but did you know that your vagina has its own microbiome, and that it contains almost 10% of your body's total bacteria? I this ep, we're talking about how an imbalance of that bacteria can negatively impact your fertility, how we might test for that, and what steps you might take to restore balance. Naturally, we'll be talking probiotics, and ending with Rebecca's entertaining detour into, drumroll...vaginal microbiome transfers.

Ever wondered if oxygen therapy could boost fertility? Have you been told to take coenzyme Q10 while trying to conceive, or maybe melatonin? In this episode, we serve up the research on antioxidants in the fertility space, and whether they're either worth trying, a waste of money, or, in some cases, possibly doing you harm. Rebecca even puts her body on the line to test one of these antioxidants…with unexpected results.

A third of cases of infertility in a couple are now attributed solely to the male, and when taken in combination with a partner's issues, that number rises up to around 50%. In this ep, we discuss fertility investigations, common male fertility problems, and what can be done to improve male fertility. We'll also touch on the growing research around male age.See omnystudio.com/listener for privacy information.

Unexplained infertility is a hard road to travel. And is it really unexplained, or have we just not found the cause yet? In this episode, we discuss how we might diagnose this complex condition better, when laparoscopy and tubal testing can be helpful, and whether IVF over IUI for these patients is likely to deliver a significantly better result. Also, is DNA fragmentation testing really worth it?See omnystudio.com/listener for privacy information.

Will losing weight before fertility treatment actually increase your chance of having a baby? The answer is more complicated than you might imagine.

We’ll also dig into practical steps for losing weight, including the fast-moving data around injectables.   See omnystudio.com/listener for privacy information.
