Why talk about this? Well… what do you remember from sex ed classes?!What is it? Definitions...What's ‘normal' 4 phases of menstrual cycle: Menstruation (winter): Day 1 of your cycle is actually the first day of your bleed. Lasts between roughly three and seven days, more for some women. Low energy. Blood pressure likely to be higher. Increase in blood glucose. Period poopsFollicular phase (spring): Around day 5-7 depending on your cycle length. Follicles in your ovaries that contain your eggs start to mature and one of them will ripen ready for ovulation. Energy levels typically start to gradually rise.Exercise - Better ability to push power and push neuromuscular 0-6 rep range with significant lean mass gains. Ovulation (summer): Around day 13 to 21 depending on your cycle length and only lasts for 2-3 days. Shortest phase of your cycle when your follicle releases an egg. Energy levels continue to rise to their peak. Luteal phase (autumn): Around day 21 to around day 28 – starts after ovulation.Energy levels start to fade during the luteal phase.  Symptoms of PMS, crave certain foods and experience mood swings. Weight fluctuations are normal up to 2.5 kg. Core temperature is elevated - drink more water to stay hydrated. RHR increases. Immune system is suppressed.Exercise - do more VO2 work and steady state training, EMOM type workouts, 6-8 rep range. Can also affect your cognition and balance - might be more clumsy. Eat enough to fuel your body – in luteal phase we burn 100-400kcals more per day. How to track? What data? Keep a track of your first day of bleeding, how long it lasts and how heavy. or more in-depth data… Apps – e.g. Wild AI app.  Basal body temperature. OTC ovulation predictor kit. Note when you're ovulating, your mood, how you're sleeping and how you FEEL. When you start doing this, you should start to see some patterns. Things that can help:ExerciseDiet: iron, eat complex carbohydrates, vegetables, beans, whole grains, full-fat dairy products, plant proteins, like beans and nuts, magnesium, reduce salt, protein.Interventions without enough research: TENS, seed cycling, the bean protocol, period patches, agnus castus, hot water bottles, painkillers, quit smoking How to know if any changes you make are working?

What foods and supplements help improve fertility for those trying to conceive naturally and for those undergoing fertility treatment. We talked with Dr. Jorge E. Chavarro, Associate Professor of Nutrition and Epidemiology at the Harvard School of Public Health and Medicine at Harvard Medical School. Dr. Chavarro’s research is focused on understanding how nutrition and lifestyle impact human reproduction. He is the Principal Investigator of the Nurses’ Health Study 3 – an ongoing prospective cohort of young professional women started in 2010 designed to investigate the role of lifestyle and biologic factors on women’s health – and leads the nutritional component of the EARTH Study, an ongoing prospective cohort of couples undergoing infertility treatment at the Massachusetts General Hospital.In this episode, we cover:How Does Nutrition Impact FertilityWe know that women are born with all the eggs they are ever going to have so how does nutrition impact female fertility and egg quality?How does nutrition impact male fertility?How does weight and BMI affect fertility?We know that the microbiome in our reproductive tract is important to fertility.
