Menopause is a natural stage in life, typically occurring around age 51. However, when it strikes earlier, it’s termed premature or early menopause. Premature menopause happens before 40, while early menopause occurs before 45. Though rare—impacting about 1% of individuals under 40 and even fewer under 30—it can significantly affect those wishing to conceive.
What is Menopause?
Menopause marks the end of menstruation due to hormonal changes, affecting anyone who menstruates. Most people undergo menopause between 45 and 55, with 51 being the average age. During this transition, the ovaries gradually produce less oestrogen and progesterone, hormones that govern the menstrual cycle and fertility. This hormonal decline leads to various physical and emotional shifts, including hot flashes, mood swings, and reduced fertility.

In the UK, around 13 million people are currently experiencing perimenopause or menopause, which is typically diagnosed after 12 consecutive months without a period.
Premature Menopause vs. Premature Ovarian Insufficiency (POI)
Premature menopause and premature ovarian insufficiency (POI) are often mistaken for one another but differ in key aspects. Premature menopause occurs when the ovaries cease regular hormone production before 40. Conversely, POI involves irregular ovarian function before menopause, characterized by fluctuating hormone levels and sporadic ovulation. POI affects 1 in 100 people under 40, 1 in 1,000 under 30, and 1 in 10,000 under 20. Those with POI may still experience occasional ovulation, thus making natural conception possible, but this chance diminishes over time.
Causes of Premature and Early Menopause
A variety of factors can lead to premature or early menopause, including:
- Genetics: A family history of early menopause increases your risk. Conditions like Turner syndrome and Fragile X syndrome are also linked to early menopause.
- Autoimmune Disorders: Illnesses where the immune system attacks the ovaries, such as autoimmune oophoritis, can trigger early menopause.
- Cancer Treatments: Chemotherapy and radiotherapy can damage ovarian function, leading to early menopause.
- Surgery: The surgical removal of one or both ovaries, often for conditions like ovarian cysts or endometriosis, can induce early menopause.
- Lifestyle Factors: Smoking, exposure to environmental toxins, and a low body mass index (BMI) have been associated with an earlier onset of menopause, though further research is needed to clarify these links.
In many cases, the exact cause of premature menopause remains unknown, catching many individuals off guard as they begin to develop symptoms.
Symptoms of Premature Menopause
Like natural menopause, premature menopause presents several physical and emotional symptoms:
- Irregular Periods: Menstrual cycles may become erratic before stopping altogether.
- Hot Flashes and Night Sweats: Sudden heat waves and night sweats can disrupt daily life and sleep.
- Vaginal Dryness and Libido Changes: Reduced oestrogen levels can lead to discomfort during sex and a decrease in sexual desire, due to thinning tissues in the vagina and urethra.
- Mood Changes: Hormonal fluctuations often result in mood swings, irritability, anxiety, and depression.
- Sleep Difficulties: Insomnia and night sweats can lead to fatigue and low energy during the day.
- Memory Issues: Some individuals may experience memory lapses or feelings of confusion.
How Premature Menopause Affects Fertility
One of the most challenging aspects of premature menopause is its impact on fertility. As the ovaries stop releasing eggs and hormone levels decline, conceiving naturally becomes increasingly difficult. However, it’s not impossible; around 5-10% of those with premature menopause may still achieve pregnancy if ovulation occurs sporadically. For those diagnosed with early or premature menopause who wish to conceive, fertility treatments are available. You can find more information on options like home insemination at Make a Mom, which is a trusted source for these topics.

Summary
Early menopause can be a life-changing experience, particularly for those aiming to conceive. Understanding the symptoms, causes, and potential fertility options can empower individuals facing this challenge. With the right support and information, it’s possible to navigate this transition effectively.
