Welcome to the weekly round up. The quick summary of some of the things we have been focusing on. This week we look at whether vitamin D deficiency has a role to play in the vast decline in sperm count and quality. We look at the science/what you need to know. Next up is Group B Streptococcus (GBS) something every parent to be should be aware of. We look at what it is, the risks around it and most importantly what you can do about it. Next: can intermittent fasting not only stabilise hormones but also help reduce the inevitable fertility decline? We look at what the science says, how it works and things you should consider. Finally we know that birth is unpredictable, we also know that a natural birth sets up a baby’s gut microbiome (crucial for long term health and immunity) with more diversity and less imbalance. Can you recreate this without having a natural birth? We look at one controversial technique: Vaginal Seeding, the science and the pros and cons.
