The menstrual cycle is not simply a monthly event - it is a dynamic reflection of endocrine, metabolic and neurological health.

Understanding ovulation and luteal phase physiology can provide valuable insight into reproductive health, fertility potential, and overall hormonal function.

Understanding your cycle goes far beyond counting days.

If you want deeper insight into ovulation, progesterone, and the health of your cycle, come and work with our team to explore the full hormonal picture.

Uterine fibroids and endometrial polyps are among the most common causes of abnormal uterine bleeding.

They are also implicated in up to ~35% of infertility cases.

While both are growths within the uterus, they arise from different tissues:
• Fibroids develop from smooth muscle within the uterine wall
• Polyps form from overgrowth of the endometrial lining

These tissues are not biologically quiet.
Fibroids and polyps often exist within an inflammatory uterine environment, showing:

• Increased COX-2 enzyme expression
• Greater mast cell activation
• Elevated inflammatory signalling

This inflammatory activity can influence endometrial receptivity, implantation, and menstrual health.

But another layer is now emerging in the research.

The gut microbiome.

Several studies have shown that women with fibroids or polyps display distinct microbial patterns compared with healthy controls, including altered diversity and shifts in microbial species.

Why might this matter?

Your gut microbiome helps regulate several systems that directly interact with reproductive physiology:

• Hormone metabolism through the oestrobolome (microbes that modulate circulating oestrogen)
• Immune signalling and inflammation
• Metabolic regulation and insulin sensitivity
• Production of short-chain fatty acids (SCFAs) that support immune balance

These pathways all influence the uterine environment.

In other words, the uterus doesn’t function in isolation.
It responds to signals coming from the gut, immune system, and metabolism.

Supporting your microbiome is one evidence-based way to help support the broader systems involved in reproductive health.

If you're working toward better periods, improved uterine health, or preparing for pregnancy, building a fertile gut foundation is a powerful place to start.

Exercise is one of the most powerful tools we have to support metabolic health, regulate inflammation, and positively influence the gut microbiome - all systems that interact with reproductive physiology.

But when it comes to fertility, exercise dose and context matter.

Research shows that very high training volumes can influence ovulation and menstrual function.

Women performing >60 minutes of vigorous exercise per day may have an increased risk of anovulation (Hakimi et al., Sports Medicine, 2017).

Energy availability also plays a major role.
In one controlled study, moderate to severe energy deficits were associated with luteal phase defects in up to 85% of women (Williams et al., 2015).

There also appears to be a dose-response relationship between exercise and conception probability.

In a large prospective cohort study:

• Women exercising 3–4 hours/week were ~27% less likely to conceive
• ≥5 hours/week was associated with ~32% lower chances of conception
• In contrast, ~2 hours of moderate activity increased the odds of pregnancy by ~15% (Wise et al., 2012)

This doesn’t mean exercise is harmful.
It means physiology responds to total stress load.

Training stress doesn’t occur in isolation. It combines with sleep quality, nutrition, emotional stress, work demands, and fertility treatment load to create what physiologists call allostatic load - the cumulative burden placed on the body.

When that load becomes too high, the body prioritises survival physiology over reproductive physiology.

This is why fertility-focused exercise programming looks different from general fitness training.

Instead of simply increasing exercise volume, we focus on:

• metabolic stability
• inflammation regulation
• gut microbiome support
• recovery capacity
• appropriate training load

Because the goal isn’t exhaustion.

The goal is creating the optimal physiological environment to suppoort healthy ovulation, implantation, early pregnancy progression and a healthy pregnancy.

Repeated implantation failure is complex.
It is rarely driven by a single variable.

Successful implantation requires a coordinated biological environment - one that supports immune tolerance, balanced inflammatory signalling, stable glucose metabolism, and appropriate hormonal regulation.

The gut microbiome plays a role in each of these systems.

• Gut microbes help regulate cytokine production and immune balance
• Short-chain fatty acids produced by beneficial bacteria support regulatory T cells involved in implantation
• The oestrobolome helps regulate circulating oestrogen
• Microbial diversity is associated with improved insulin sensitivity and metabolic stability

When we expand the lens of fertility care to include gut–immune–hormone physiology, we open up more ways to support the body during IVF and embryo transfer.

This systems-based approach isn’t new to us. For years we have worked beyond the traditional focus on the ovaries and uterus alone, recognising that reproductive outcomes are shaped by whole-body physiology - including the microbiome.

Research can take 17 years to be put into practice but we have been applying it already. The recent findings of Zhang et al. (mBio, 2025 are not news to us but if you want more supporting evidence it just keeps coming.

Zhang and colleagues found that in women undergoing frozen embryo transfer (FET), the gut microbiome showed the greatest differences between those who experienced successful implantation and those who did not.

The authors concluded that microbiota-associated metabolic pathways may represent a promising target to enhance FET success rates, and could also provide novel biomarkers for predicting implantation outcomes.

In other words, the gut microbiome helps shapes the biological environment in which implantation occurs.

We have spent years researching and applying microbiome science in fertility care - translating emerging evidence into practical strategies that support women through IVF and beyond.

We even wrote a book on it: Create a Fertile Gut. It’s available via the link in bio if you love science and want the practical strategies for success.

Ovarian stimulation influences follicle growth in the present cycle.
But egg and s***m quality are shaped months earlier.

• S***m maturation takes on average approximately 75 days
• The dominant follicle in a retrieval cycle has been developing for 3-4+ months
• Mitochondrial function, inflammation, and metabolic signalling influence gamete competence

The gut microbiome plays a measurable role in these systems.

Research links microbial diversity with improved insulin sensitivity, reduced inflammatory signalling, and enhanced metabolic flexibility - all of which influence reproductive physiology.

This isn’t about doing more.

It’s about working with biology, not against it.

When you build metabolic and microbial stability, you’re strengthening the terrain - not just the timeline.

Exercise is not “just exercise” when you’re trying to conceive.

It’s physiology. It’s signalling. It’s strategy.

Every fertility journey is shaped by underlying drivers - inflammation, oxidative stress, metabolic health, microbiome balance, stress load, sleep, and training history. A generic program doesn’t address those variables. A targeted prescription does.

This is why we love being specialists in exercise prescription for fertility.

We look beyond steps and sweat.
We assess inflammatory load.
We consider oxidative stress and mitochondrial demand.
We integrate gut–microbiome health.
We periodise training around stimulation cycles, transfers, natural cycles and early pregnancy physiology.

Because exercise can either support implantation and hormonal balance… or compete with it.

Our role is to ensure it supports.

And we don’t stop at a positive test.
We walk with you through pregnancy, adapting to trimester-specific physiology, and into postpartum - rebuilding strength, metabolic health and pelvic function with intention.

The ultimate goal is shared.

We’ve sat on the other side of the consult room.
We understand the weight of every cycle.
And we apply science with care because this isn’t theoretical - it’s personal.

Fertility-focused exercise.
Grounded in physiology.
Delivered with lived understanding.

Embryo quality matters.
But implantation is also about environment.

The uterus doesn’t function independently - it responds to immune signals, metabolic status, and hormone metabolism. Your gut microbiome helps regulate each of these systems. 🌱

Supporting your microbiome with evdience based strategies can help create a more stable immune and metabolic environment.

Implantation isn’t just a moment.
✅ It’s the result of coordinated physiology.

And physiology can be supported.

Your gut might just be the missing link in male fertility.

Emerging research shows that gut microbes don’t just influence digestion. They shape hormone balance, inflammation, nutrient absorption, and even s***m quality and DNA integrity.

It’s time we talk about it.

That’s why we’re proud to join the Fertility4Men Virtual Summit (24–25 Oct), a free two-day online event created by David Ireland, founder of

After navigating his own long fertility journey - through multiple rounds of IVF, shifting diagnoses, and endless uncertainty - David set out to give men what he wished he’d had: clarity, structure, and science-backed support.

Now, he’s bringing together leading fertility experts from around the world (including us at The IVF Project) to help men take charge of their health, hormones, and microbiome, one evidence-based step at a time.

🌸 Keeping It Simple: Protecting Your Vaginal Microbiome During IVF

Many women preparing for IVF want to do everything possible to support success - from nutrition to hygiene. But one area that often flies under the radar is intimate washing.

A large Danish study of over 1,500 IVF patients (2017–2022) found that:

⚪️Around 1 in 3 women had signs of va**nal dysbiosis (an imbalance in va**nal bacteria).

⚪️Women who used intimate soaps or douches were significantly more likely to have dysbiosis.

⚪️In contrast, those who used water only had the healthiest va**nal microbiota - rich in Lactobacillus, the protective bacteria linked to better IVF outcomes.

🧼 Why this matters:
A balanced va**nal microbiome - dominated by Lactobacillus - is a natural defense system. It helps protect against inflammation and infection, supports endometrial health, and is linked to higher embryo implantation rates.

But soaps and douching can strip away these beneficial bacteria, raising va**nal pH and encouraging less-friendly microbes (like Gardnerella or Streptococcus) to grow.

💧 What to do instead:
✅ Clean the v***a gently with water only - your va**na is self-cleansing.
🚫 Skip douches, soaps (even “pH-balanced” ones), and wipes marketed as “intimate care.”
🩸 If using menstrual products, menstrual cups were associated with a lower rate of dysbiosis in this study - another gentle choice worth considering.

🌿 Bonus tip:
Supporting your gut microbiome - through a fibre-rich diet and prebiotic support - also nurtures your reproductive tract microbiome. The two are connected! A healthy gut supports balanced inflammation, immune function, and microbial cross-talk that benefits the va**nal and uterine environment.

✨ Takeaway:
If you’re preparing for IVF, sometimes less is more.
➡️ Stick to water only for intimate care - no soaps, no douching - and nourish your microbiome from the inside out.

🧬 Did you know your uterus only has a short 24-hour window when it’s receptive to an embryo?

This “window of implantation” happens thanks to genetic shifts in the endometrium. When receptive, genes that regulate adhesion, cell growth, and metabolism are switched on opening the door for an embryo to implant.

But even with high-quality blastocysts, the home they’re placed into matters.

✨ Insulin plays a surprisingly big role here. High insulin levels can disrupt uterine receptors and reduce the chance of implantation. Women with insulin resistance have been shown to have lower implantation and live birth rates, even in IVF cycles with good embryos.

So what can we do to support this critical window?

🔑 Three key regulators of insulin:

1. Exercise
Just one session of exercise can boost insulin sensitivity within 24 hours! But the benefits fade in a few days so consistency matters. The right exercise prescription (moderate, vigorous, or intervals) depends on you.

2. Nurture your gut microbes
Your microbiome produces short-chain fatty acids like butyrate, which improve insulin control and reduce inflammation. Low diversity = higher insulin resistance. Diet is the strongest modulator: think fibre, prebiotics, and polyphenols to feed your microbes.

3. Sleep
Even one night of poor sleep can reduce insulin sensitivity by 20–25%. Chronic disruption raises insulin resistance more than a high-fat diet. Quality, consistent sleep is one of the most underrated fertility tools.

🌱 Fertility isn’t just about the embryo, it’s about creating the most welcoming environment possible. Supporting insulin sensitivity through movement, gut health, and sleep helps you optimise that precious 24-hour window.

☀️ Did you know 80% of our vitamin D comes from sunlight?

With shorter days, more time indoors, or living further from the equator, it’s no wonder vitamin D deficiency is so common.

And it matters because vitamin D receptors are found in nearly every tissue of the body, including the ovaries, endometrium, fallopian tubes… and even our gut.

✨ Vitamin D + Your Gut Microbiome

Here’s the fascinating part: while vitamin D supports bone, muscle, fertility, and immune health, your gut microbiome helps determine how effectively you can activate and use it.

In turn, vitamin D helps regulate microbial balance, gut barrier integrity, and the production of natural antimicrobials that keep your immune system in check.

🔬 Science highlights:

🌱Females deficient in vitamin D have 26% lower chance of live birth via IVF/ICSI.
🌱In men, vitamin D levels correlate with testosterone, s***m quality, and motility.
🌱67–85% of women with PCOS have low vitamin D.
🌱Among sub-fertile women, up to 91% present with deficiency.

🌿 It’s a two-way street: vitamin D supports your gut, and your gut microbiome supports your vitamin D. Together, they influence fertility, immunity, and whole-body health.

👉 Getting your levels checked before conception (or IVF) is one of the most science-backed steps you can take.

How’s your vitamin D status? Do you have a gut–hormone plan in place to optimise it?
