Causes of Low Progesterone

Low progesterone levels can lead to menstrual irregularities, and many women may also experience infertility. These consequences are serious, and women should promptly visit a hospital for endocrine testing. Once diagnosed, appropriate and comprehensive treatment measures can be initiated. So, what are the causes of low progesterone? Let’s explore them below.

Causes of Low Progesterone

1. Endocrine Imbalance

Low or suboptimal progesterone levels are often caused by endocrine disorders, potentially resulting in menstrual irregularities or infertility. It is recommended to undergo endocrine testing at a hospital and receive targeted treatment based on the test results. In daily life, excessive mental stress, irregular sleep and wake cycles, poor sleep quality, and erratic eating habits can all contribute to endocrine dysfunction.

　　2. Poor Follicular Development

Progesterone is a progestogen primarily secreted by ovarian follicles. During ovulation, granulosa cells of mature follicles undergo luteinization under the influence of the luteinizing hormone (LH) surge, initiating the secretion of small amounts of progesterone. If follicles fail to mature adequately, granulosa cells cannot be stimulated to secrete progesterone. Additionally, absence of the LH surge prevents luteinization and thus progesterone secretion. Consequently, insufficient secretion leads to low progesterone levels.

3. Age-Related Factors

As women age, the function of the endocrine system gradually declines. Progesterone levels are closely linked to endocrine function. While nutritional status also influences progesterone production, endocrine function plays a critical role. Diminished or impaired endocrine function reduces the secretion of hormones that promote progesterone synthesis, thereby lowering overall progesterone levels in the body.
　　4. Malnutrition in Women

Progesterone synthesis requires certain foundational substances—such as proteins, carbohydrates, amino acids, and cytokines. Deficiency in any of these nutrients—even if all other physiological functions remain normal—can result in decreased progesterone levels.

The above outlines the primary causes of low progesterone. We hope this information proves helpful to you.
