Anti-Mullerian Hormone (AMH) is a protein hormone produced by granulosa cells in the small follicles of the ovaries. Granulosa cells support egg development, and AMH levels are highest when follicles are in the preantral and small antral stages. As follicles mature, AMH production decreases. AMH levels remain stable from day to day due to the constant presence of preantral and small antral follicles. This stability allows AMH testing to be performed at any time during a woman’s cycle to assess her ovarian reserve.
Everything You Need to Know About Low AMH
Low AMH levels indicate a reduced number of preantral follicles in the ovaries. While AMH naturally decreases with age, lower AMH levels at a younger age may signal premature ovarian failure and reduce the likelihood of natural conception. In India, a survey found that nearly half of women aged 20-40 had low AMH levels.
Several factors can contribute to low AMH levels:
• Age: Women are born with a finite number of eggs, which diminish over time. As a woman ages, AMH levels decrease, particularly in her mid-30s, leading to reduced fertility.
• Poor Diet: Unhealthy eating habits can lead to obesity, which can impact AMH levels.
• Endometriosis: This condition, characterized by the growth of uterine tissue outside the uterus, can inflame the ovaries and affect AMH production.
• PCOS (Polycystic Ovary Syndrome): This common reproductive disorder, marked by an excess of male hormones, can lead to elevated AMH levels and affect fertility.
• Genetics: Hereditary factors may play a role in low AMH levels.
• Autoimmune Diseases: Conditions where the immune system attacks healthy cells, including eggs, can lower AMH levels.
• Cancer Treatments: Chemotherapy or radiation can damage ovarian follicles, leading to reduced AMH levels.
• Mental Health: Stress and mental health issues may impact AMH levels and fertility.
• Lifestyle Changes: Factors like smoking, obesity, and vitamin deficiencies can also affect AMH levels.
Low AMH levels often do not present specific symptoms. General signs such as irregular periods, short menstrual cycles, or early menopause may indicate low AMH levels.
AMH levels indicate ovarian reserve but do not directly correlate with fertility. While lower AMH can signify reduced egg quantity and potentially affect conception, the overall fertility also depends on factors like egg quality and partner’s sperm. Younger women with low AMH may still conceive, but those with significantly low levels may need medical intervention.
Consult with a fertility specialist to explore available options. Lifestyle changes can help improve AMH levels. Treatments and interventions may include:
• Yoga and Exercise: Regular physical activity can support overall reproductive health.
• Balanced Diet: Eating a nutritious diet can positively impact AMH levels.
• Acupuncture: Some studies suggest acupuncture may benefit reproductive health.
• DHEA Supplements: DHEA is a hormone that may improve egg quality and quantity.
IVF can be a viable option for those with low AMH levels, making use of the remaining eggs. If FSH levels are also elevated, indicating poor egg quality, IVF might still succeed with proper management and supplements. For women with extremely low AMH and no viable eggs, using donor eggs in IVF may be considered.
1. Does AMH reveal my current chances of pregnancy?
AMH levels do not predict immediate pregnancy chances but indicate ovarian reserve. Factors like fallopian tube condition and sperm quality also affect fertility. Regular cycles and a healthy lifestyle can still lead to conception even with low AMH.
2. Can AMH predict future fertility?
AMH levels can offer insights into ovarian reserve and potential premature menopause. Regular testing can help with early intervention.
3. Does low AMH mean I am infertile?
Not necessarily. Low AMH indicates reduced ovarian reserve but does not equate to infertility. Regular ovulation and a healthy lifestyle can still support fertility.
4. Does high AMH mean I am highly fertile?
High AMH does not guarantee high fertility. Conditions like PCOS can cause high AMH levels and affect menstrual cycles. However, high AMH levels may lower the risk of early menopause and improve IVF success.
5. Why do fertility clinics check AMH levels?
Fertility clinics use AMH tests to assess ovarian reserve and predict how many eggs might be viable for IVF. This helps in planning the appropriate fertility treatments.
