How Low AMH Affects Menstrual Cycle Regularity?

Anti-Müllerian Hormone (AMH) is a crucial marker in assessing a woman’s ovarian reserve, which is a measure of her reproductive potential. This hormone, secreted by the ovarian follicles, is vital for understanding how well the ovaries are functioning. When AMH levels are low, it can have a significant impact on menstrual cycle regularity, which is essential for overall reproductive health. In this blog, we will delve into the ways low AMH affects menstrual cycles, explore the underlying mechanisms, and discuss potential management strategies.

Understanding AMH and Its Role in Reproductive Health

AMH is produced by the Pre-antral and antral follicles granulosa cells early stage of developing ovarian follicles. It plays a key role in regulating the growth of these follicles and in the overall health of the ovaries. High levels of AMH generally indicate a good ovarian reserve, meaning a higher number of available eggs. Conversely, low AMH levels suggest a reduced ovarian reserve, which can impact various aspects of reproductive health, including menstrual cycle regularity. Abnormally high AMH levels are often seen in women with PCOS.

How Low AMH Affects Menstrual Cycle Regularity?

• Irregular Menstrual Cycles

Low AMH levels are a sign of diminished ovarian reserve which can lead to irregular menstrual cycles, which may include:

• Skipped Periods: Women with low AMH may experience missed periods or significant gaps between cycles. This occurs because the hormonal signals necessary for regular ovulation are disrupted.

   

• Variable Cycle Length: The length of the menstrual cycle can become inconsistent, ranging from shorter to longer than the typical 26-35 days. This irregularity results from unpredictable ovulation patterns and hormonal imbalances.

• Decreased Follicle Count

AMH is secreted from small ovarian follicles. Low AMH levels are associated with:

• Fewer Ovarian Follicles: With a lower number of follicles, the ovaries may not produce eggs consistently. This can lead to reduced frequency of ovulation and, consequently, irregular menstrual cycles.
   
• Decreased Egg Reserve: A reduced number of eggs impacts the regularity of ovulation. Since fewer eggs are available for release, hormonal regulation becomes erratic, affecting the menstrual cycle.

• Disrupted Ovulation

Regular ovulation is essential for a stable menstrual cycle. Women with  Low AMH levels may experience:

• Inconsistent Ovulation: Women with low AMH may experience irregular or absent ovulation, which disrupts the menstrual cycle. Without regular ovulation, the hormonal feedback loops that regulate menstruation are interrupted.

   

• Anovulation: In some cases, low AMH can lead to anovulation, where the ovaries do not release an egg during a cycle. This results in missed periods and irregular bleeding.

• Hormonal Imbalances

Low number of developing follicles may disturb the hormonal feedback with brain hormones that regulates the menstrual cycle. This can contribute to:

• Hormonal Fluctuations: Imbalances in hormones such as estrogen and progesterone can occur. These fluctuations can cause irregular periods, heavy bleeding, or spotting between cycles.

   

• Altered Hormone Production: The ovaries’ ability to produce hormones needed for a regular menstrual cycle may be compromised, leading to disruptions in cycle length and flow.

• Age-Related Factors

While low AMH levels can occur at any age, they are often linked to:

• Advanced Maternal Age: As women age, AMH levels naturally decline, reflecting a reduced ovarian reserve. This age-related decline can result in more pronounced menstrual irregularities.

   

• Early Ovarian Aging: In some cases, low AMH can be an indicator of early ovarian aging, which may lead to irregular cycles and reduced fertility at a younger age.

Diagnosing and Evaluating Low AMH

Testing: To assess AMH levels, a simple blood test is conducted. This test is typically done in conjunction with other fertility assessments to provide a comprehensive picture of ovarian health.

Evaluation: In addition to measuring AMH levels, evaluating menstrual history and performing other diagnostic tests can help determine the impact on menstrual cycle regularity. This may include:

• Tracking Menstrual Cycles: Keeping a detailed record of menstrual cycles can help identify patterns or irregularities.

   

• Assessing Hormonal Levels: Testing other hormones, such as FSH (follicle-stimulating hormone) and LH (luteinizing hormone), can provide further insights into menstrual irregularities and ovarian function.

   

• Ultrasound : ultrasound measurement of AFC or antral follicles is also one of the reliable methods to evaluate ovarian reserve. 

Managing Low AMH and Menstrual Irregularities

Lifestyle Adjustments: Adopting a healthy lifestyle can help marginally improve menstrual cycle regularity. Consider:

• Balanced Diet: Eating a nutritious diet rich in vitamins and minerals can support overall reproductive health.

   

• Regular Exercise: Engaging in regular physical activity can help maintain hormonal balance and support a regular menstrual cycle.

   

• Stress Management: Reducing stress through relaxation techniques and mindfulness can positively impact menstrual regularity.

Medical Treatments: Depending on the extent of low AMH and menstrual irregularities, treatment options may include:

• Hormonal Therapies: Medications such as birth control pills or hormone replacement therapy can help regulate menstrual cycles and manage symptoms but are ineffective at treating the root cause.

   

• Fertility Treatments: For women experiencing low AMH significant challenges, fertility treatments such as IVF (In Vitro Fertilization) may be considered. These treatments can help address irregular cycles and improve chances of conception.

Consultation with Specialists: Consulting with a fertility specialist is crucial for managing low AMH and menstrual irregularities. Specialists can:

• Provide Personalized Care: Develop a tailored treatment plan based on individual needs and health conditions.

   

• Offer Support and Guidance: Address specific concerns and provide ongoing support throughout the management process.

FAQs 

What are the normal ranges for AMH levels, and how do low levels compare?

AMH levels vary based on age and individual health. Generally, levels below 2.2 ng/mL are considered low from fertility perspective , but what’s normal can differ based on various factors such as age. AMH levels are also measured in pmol. The cutoff value differs between units of measurement.

Can low AMH levels affect the quality of menstrual flow?

Usually Low AMH levels primarily affect cycle regularity and ovulation, and are not associated with changes in menstrual flow, such as lighter or heavier periods.

How does low AMH impact fertility treatments like IVF?

Low AMH levels can reduce the number of eggs retrieved during IVF, potentially affecting the success rate of the treatment.

Are there specific age-related thresholds where low AMH becomes more concerning?

No low AMH can occur at any age. All age group women should take it seriously. Although younger women with similar AMH  levels have better reproductive outcomes.

How can low AMH levels affect the likelihood of achieving pregnancy without fertility treatments?

Low AMH levels can decrease the chances of natural conception due to reduced egg reserve and irregular ovulation.
