Androstenedione

What is Androstenedione?

Androstenedione is a steroid hormone primarily produced by the adrenal glands, ovaries, and testes. It functions as a precursor to both testosterone and estrogen, and is classified as an androgen due to its role in the development of male characteristics and hormone balance.

Androstenedione in Women

In women, androstenedione is mainly produced by the ovaries and adrenal glands. It is then converted into estrone (a form of estrogen) and small amounts of testosterone in peripheral tissues such as fat and muscle. This process plays a role in regulating reproductive health and hormonal balance.

Androstenedione in Men

In men, androstenedione is produced predominantly by the testes and is converted into testosterone, supporting male secondary sex characteristics, libido, and muscle mass.

Diagnostic Use of Androstenedione Testing

Androstenedione levels can be measured via a blood test and are often used to:

Evaluate adrenal gland function

Diagnose and monitor conditions such as polycystic ovary syndrome (PCOS)

Investigate hormone-secreting tumours and certain types of cancers

This hormone is particularly important in fertility and endocrine assessments, especially in women experiencing irregular cycles or signs of androgen excess.

Interpreting Androstenedione Levels

It’s important to note that androstenedione levels can vary based on age, sex, and individual hormonal profiles. Abnormal levels do not always indicate a specific medical condition. A comprehensive clinical evaluation, along with additional hormone testing, is often required for accurate diagnosis.
