Androgenetic alopecia is a common form of hair loss, especially in men. It is also known as male-pattern baldness. The condition is characterized by the progressive shedding of hair from the scalp, resulting in a receding hairline and thinning of hair on the crown of the head. In women, it is called female-pattern baldness and may result in a widening of the parting or thinning of the hair.
The exact causes of androgenetic alopecia are still unclear, but it is believed to be influenced by both genetic and hormonal factors. Research has shown that genetic factors play a significant role in the development of this condition. Studies have identified several genes associated with the condition, including the androgen receptor gene and genes involved in hair follicle development and function.
Androgenetic alopecia is thought to be inherited in an autosomal dominant pattern, where an affected individual has a 50% chance of passing on the condition to each of their children. However, the inheritance pattern for this condition can be more complex, and there may be other genetic and environmental factors that contribute to its development.
There are several resources available for patients and their families to learn more about androgenetic alopecia. The Genetic and Rare Diseases Information Center (GARD) provides comprehensive information about the condition, including its causes, symptoms, and treatment options. PubMed and OMIM are valuable sources of scientific articles and references related to the condition. ClinicalTrials.gov provides information about ongoing clinical trials and research studies aimed at understanding the genetic and molecular basis of androgenetic alopecia.
Frequency
The frequency of androgenetic alopecia, or male-pattern baldness, varies depending on gender and age. It is a very common condition, affecting both men and women.
In men, androgenetic alopecia is the most common form of hair loss, with a reported prevalence of up to 80% by the age of 80. It typically presents as a receding hairline and thinning of the hair on the crown of the head.
If your health insurer denies your claim or treatment, you have very little time to act. Appeals to Medicare must be filed within 90 days in the most lenient states, with even shorter deadlines in some states, and many insurers and healthcare providers will turn over unpaid medical bills to collection agencies after just 60 days, the AARP
In women, the frequency of androgenetic alopecia is lower compared to men, but it still affects a significant number of individuals. The prevalence increases with age, with around 40% of women being affected by the age of 70.
The condition is believed to be influenced by both genetic and hormonal factors. Genetic factors play a major role in the development of androgenetic alopecia, in particular, the inheritance of certain genes related to hair follicle sensitivity to androgen hormones.
Androgenetic alopecia is associated with other conditions such as polycystic ovary syndrome (PCOS) and prostate cancer. The exact mechanisms underlying these associations are unclear and require further research.
Research studies, clinical trials, and advocacy organizations provide additional resources and information about androgenetic alopecia. Some useful resources include PubMed, OMIM, ClinicalTrials.gov, and various scientific articles and research studies.
Overall, the frequency of androgenetic alopecia is high, affecting a large number of individuals of both genders. It is a condition that can have significant impacts on self-esteem and quality of life, and therefore, support and awareness of this condition are important.
Causes
The exact causes of androgenetic alopecia, also known as male-pattern baldness or female-pattern baldness, are still unclear. However, several factors have been associated with the condition.
- Genetics: Androgenetic alopecia has a strong genetic component, with genes playing a significant role in its development. It has been found that certain genes, such as the AR gene and the SRD5A2 gene, are involved in the inheritance of this condition.
- Androgens: Androgens, which are male sex hormones like testosterone, play a significant role in androgenetic alopecia. The sensitivity of hair follicles to androgens is thought to be a contributing factor to the condition.
- Hormonal imbalance: Hormonal imbalances, such as those caused by conditions like polycystic ovary syndrome (PCOS), can lead to androgenetic alopecia in women. These imbalances affect the hair growth cycle and can result in hair loss.
- Other associated conditions: Androgenetic alopecia has been found to be associated with other conditions, including insulin resistance, coronary heart disease, and prostate cancer. These associations suggest potential shared genetic or hormonal factors among these diseases.
- Additional factors: Other factors that may contribute to androgenetic alopecia include aging, stress, and certain medications. While these factors may not directly cause the condition, they can exacerbate hair loss in individuals who are already predisposed to it.
For more information on the causes of androgenetic alopecia, you can refer to the following resources:

Learn more about the gene associated with Androgenetic alopecia
Androgenetic alopecia, also known as male and female pattern baldness, is a common form of hair loss that affects millions of people worldwide. It is a genetic condition that is believed to be inherited from both parents. The exact causes of androgenetic alopecia are still unclear, but research has shown that a gene called the androgen receptor gene (AR gene) plays a significant role in the development of this condition.
The AR gene is responsible for producing a protein called the androgen receptor, which is involved in the growth and regulation of hair follicles. This gene is located on the X chromosome, which means it is inherited differently in men and women. Men have one X chromosome and one Y chromosome, while women have two X chromosomes. Therefore, if a man inherits a faulty AR gene from his mother, he is more likely to develop androgenetic alopecia. Women have a higher chance of inheriting the condition if their father or maternal grandfather experienced hair loss.
Studies have shown that the frequency of the AR gene in men with androgenetic alopecia is higher compared to those without the condition. Additionally, research has found that variations in the AR gene are associated with an increased risk of developing the disease.
While the role of the AR gene in androgenetic alopecia is well-established, it is important to note that other genetic factors also contribute to the development of this condition. Scientists continue to study the genetic basis of androgenetic alopecia and hope to identify additional genes that may be involved.

Inheritance
Androgenetic alopecia is a condition that can be inherited. It is also known as male-pattern baldness or female-pattern baldness, depending on the gender of the affected individual. The condition is caused by a combination of genetic and hormonal factors.
Research studies have found that androgenetic alopecia is associated with certain genes. In women, the condition has been associated with a gene called the androgen receptor gene, located on the X chromosome, while in men, it is associated with genes on both the X and Y chromosomes. Additional genes and factors also play a role in the inheritance of this condition.
It is important to note that the inheritance pattern of androgenetic alopecia is still unclear. While the condition tends to run in families, it does not follow a simple pattern of inheritance like many other genetic diseases. Instead, it is believed to be influenced by multiple genes and environmental factors.
Further research is needed to fully understand the inheritance of this condition. Studies are ongoing to identify the specific genes and factors that contribute to androgenetic alopecia. Clinical trials (registered on clinicaltrialsgov) are being conducted to gather more information about the genetics of this condition and to support advocacy and research efforts.
