Whether you’re trying to conceive, living with PMOS ( formerly known as PCOS), considering egg freezing, navigating perimenopause, or simply trying to understand what your hormones are doing, you are not alone. Reproductive health can feel confusing, especially when symptoms are dismissed, cycles become unpredictable, or you’re told to “just wait and see” without clear answers. But your questions deserve more than vague reassurance. They deserve clinical context, personalised support and practical next steps. Welcome to Your Questions Answered with Hertility,  our expert-led series answering the reproductive health, hormone and fertility questions you really want answered. I’m Zoya Ali, Hertility’s Senior Scientific Research Associate, and in this series I’ll be helping to break down complex fertility and hormone topics in a way that feels clear, clinically grounded and easy to understand. From irregular periods and PMOS to egg freezing, perimenopause and trying to conceive, my goal is to give you evidence-based information without shame, confusion or medical jargon. In this edition, we’re answering some of the most common questions we hear from the Hertility community, including what to do if you feel dismissed by your GP, whether egg freezing in your early thirties is worth it, why a PMOS diagnosis matters, and whether pregnancy is still possible during perimenopause. Have a question you’d like answered in a future edition of Your Questions Answered with Hertility? Submit your question here. Q: We’ve been trying to conceive for over a year. My GP told me to lose weight and said ovulation can happen at any time. I only get a period once every three months. I feel pushed aside. What can I do? First, I’m really sorry you’ve been made to feel like this, your concerns are completely valid. After 12 months of trying to conceive, you are entitled to a comprehensive fertility assessment. Being told to lose weight and come back later, with no investigations or plan is not adequate care and you deserve more than that. Now, let’s talk about what’s actually going on with your body, because irregular periods every three months are telling us something important. That pattern is known as oligomenorrhoea and it is a sign that your body may not be ovulating regularly. Ovulation is the event that makes conception possible, and if it’s only happening sporadically, or not at all, trying to conceive can become significantly harder. Weight can be one piece of this picture, and it’s worth being honest about that. Weight can affect how the body manages insulin and inflammation, both of which influence reproductive hormones and ovulation. But weight is one factor in a much larger story, and it should never be used as a reason to withhold investigations. The most common cause of irregular, infrequent periods is PMOS ( previously known as PCOS ) which is a hormonal and metabolic condition affecting how the ovaries function. But thyroid imbalance, raised prolactin, insulin resistance and stress can all produce a very similar picture. You cannot know which of these is driving your symptoms without testing. If you feel your GP is still not listening, you are entitled to ask for a referral to a gynaecologist or fertility specialist, or to seek a second opinion. At Hertility, our Advanced At-home Hormone and Fertility Test can give you clinical-grade results, insight into your egg count and screening for up to 18 reproductive health conditions, alongside a doctor-written report, personalised Care Plan and a Clinical Result Review Call. We also offer Fertility Nutrition Consultations that can support ovulation, hormone and metabolic health without shame, blame or crash dieting. You don’t have to wait to be taken seriously. Q: What is the success rate for egg freezing if you freeze your eggs in your early thirties? This is one of the most common questions I hear from people considering egg freezing, and I understand why, you want a number, something reassuring and concrete. The honest answer is that there isn’t one single success rate, let me explain why, and what the picture actually looks like. Age is genuinely one of the most important factors in egg freezing. Freezing in your late twenties to early thirties is the most recommended, because egg quality and quantity are typically the best. But age alone doesn’t determine your outcome, two women who are both 31 can have very different responses to fertility treatment depending on factors like their AMH levels and antral follicle count. When we talk about success rates, we’re really talking about a chain of events, and at each link in that chain, some eggs are naturally lost. First, your frozen eggs need to survive the thawing process, thaw survival rates are typically around 80 to 90%. Then, not every thawed egg will fertilise successfully. Not every fertilised egg will develop into a good-quality embryo. And not every embryo will implant and lead to a pregnancy. Sperm quality and uterine health both play a role at that final stage too. Most clinics recommend aiming for around 15 mature eggs to give yourself a reasonable chance of a future live birth, with some recommending closer to 20 if you’re hoping for more than one child. Depending on how your ovaries respond to stimulation, some people collect enough eggs in one cycle; others need two or more. This is why egg freezing planning really is personal, it’s not a one-size approach. An AMH blood test and pelvic ultrasound to check our Antral Follicle Count (AFC) are the best starting points for understanding your ovarian reserve. They can’t tell us about egg quality directly, that remains something we can only assess once eggs are fertilised, but they give us a meaningful picture of quantity and potential response to fertility medications. At Hertility, our Advanced At-home Hormone and Fertility Test includes insight into your egg count alongside a full hormone profile. We can also arrange a Pelvic Ultrasound Scan to assess your antral follicle count and pelvic structures, and we work with HFEA-accredited partner clinics to support a smooth referral process […]

Polyendocrine metabolic ovarian syndrome (PMOS) is the condition you may still know as polycystic ovary syndrome (PCOS). It’s one of the most common hormonal conditions, affecting around 1 in 8 women. But despite the old name, it has never been just about the ovaries. PMOS can affect your periods, ovulation, skin, hair, metabolism, fertility, sleep and mental health. It can also look completely different from one person to another. One person may have very irregular periods and excess facial hair, while another has acne, fairly regular cycles and no obvious symptoms until they start trying to conceive. That variation is one of the reasons PMOS can be difficult to recognise and why diagnosis is sometimes delayed. Whether you have recently been diagnosed, think your symptoms could be linked to PMOS, or have been living with the condition for years, this guide covers PCOS symptoms, diagnosis, fertility, treatment, nutrition and long-term health. Quick facts:  If you are wondering whether your symptoms could be linked to PCOS, Hertility’s Advanced Hormone and Fertility Test can help build a clearer picture of your hormones, cycle and symptoms to help you understand what’s going on. Why was PCOS renamed PMOS? On 12 May 2026, the international PCOS community officially adopted the name polyendocrine metabolic ovarian syndrome, or PMOS. The previous name, polycystic ovary syndrome, could be misleading for several reasons. Firstly, the “cysts” associated with PCOS are not typical ovarian cysts. They are usually small ovarian follicles containing immature eggs. Secondly, you can have the condition without having polycystic-looking ovaries at all. Most importantly, the old name placed the emphasis on the ovaries when the condition can affect much more than reproductive health, including metabolism, hormones, mental wellbeing and long-term health. The new name was developed through an international process involving healthcare professionals, researchers and people living with the condition. If you already have a PCOS diagnosis, you do not need to be diagnosed again. Your diagnosis has not changed. You will also continue to see the term PCOS in medical records, research and online searches, which is why we use both PCOS and PMOS throughout this guide. Read more: PCOS has been renamed PMOS — here’s what that means for you. How common is PCOS? The World Health Organization estimates that PMOS affects up to 13% of women of reproductive age, making it one of the most common hormonal conditions worldwide, and that up to 70% of those affected may not know they have it. In the UK, the NHS estimates it affects about 1 in every 10 women. Part of the problem is that there’s no single way it presents. Diagnosis can also take time. In one international study, over a third of people with PCOS waited more than two years for a diagnosis, and almost half saw three or more health professionals before getting one. What are the common symptoms of PCOS? PCOS symptoms can affect your menstrual cycle, skin, hair, metabolism, sleep, mood and fertility. You do not need to have every symptom to have the condition. Menstrual cycle-related symptoms One of the most common features is irregular ovulation. which can make periods longer, unpredictable or absent for months, sometimes with heavier or prolonged bleeding after a long gap.  You may ovulate later, less often, or not at all in some cycles (an anovulatory cycle). In adults more than three years past their first period, cycles shorter than 21 days, longer than 35 days, or fewer than eight a year are considered irregular. Having regular periods don’t completely rule out PCOS, though more on that below.  If you want to understand your own cycle, see our guide Menstrual Cycle 101: Your Complete Guide to How Your Cycle Works Skin and hair-related symptoms Higher androgen activity (androgens include hormones like testosterone) can contribute to acne, oily skin, excess facial or body hair (known as hirsutism), often on the chin, upper lip, chest, abdomen or back, and scalp hair thinning, often noticed as a widening parting.  Hair-growth patterns vary a lot between individuals and ethnic groups, which matters when symptoms are assessed. Some people also develop acanthosis nigricans, darker, thicker, velvety-looking skin around the neck or underarms, which can be linked to insulin resistance. To find out more about how hormones affect your skin, read our guide to skin and hair changes. Weight gain or difficulty losing weight Some people experience weight gain or find weight harder to manage, but you don’t need to be overweight to have PCOS. It affects people across all body sizes, and insulin resistance can occur in people who aren’t overweight. Fatigue and sleep problems Significant tiredness is common, although fatigue has many causes and shouldn’t automatically be blamed on hormones. Obstructive sleep apnoea is more common in PMOS, even after taking BMI into account. So if you snore, wake up unrefreshed or feel tired all day, it’s worth talking to a healthcare professional. Mental health-related symptoms PCOS isn’t only physical. Depression and anxiety are more common, and symptoms like acne, unwanted hair growth, fertility difficulties, body-image concerns and weight stigma can all affect quality of life. Current guidance recommends that psychological wellbeing forms part of PMOS care, including screening and support for depression, anxiety and eating disorders. Difficulty conceiving PCOS is a leading cause of irregular ovulation and anovulatory infertility. If ovulation happens less often, there are fewer chances for egg and sperm to meet. But that’s very different from saying everyone with PCOS is infertile; many conceive naturally, and effective treatments exist when ovulation needs support. What causes PCOS? There is no single known cause of PCOS. Instead, it appears to develop through a combination of genetics, hormone signalling, ovarian function, metabolism and environmental factors. Two factors that are particularly important are androgens and insulin. High levels of Androgens Androgens are a group of hormones, the most common being testosterone. They are produced mainly by the ovaries and adrenal glands and have roles in reproductive health, bone and muscle health, sexual function and wider physiology. […]
