Patient's question:
Female, 31 years old, due to work reasons, often drinks and stays up late. Yesterday, she went to the hospital for a check-up and was diagnosed with premature ovarian failure.Doctor's answer:
Common Causes of Premature Ovarian FailureThe causes of premature ovarian failure are complex and are often due to a combination of factors. In the majority of patients, the exact cause remains unclear. It is believed to be related to genetic factors, autoimmune processes, infections, and endocrine disorders.
1. Physical and Chemical Factors
Radiation exposure, chemical drugs, and possible infectious factors. Radiation exposure can damage the ovaries, leading to temporary or permanent amenorrhea. Chemotherapy drugs, whether used alone or in combination, often cause ovarian failure.
2. Genetic Factors
The maintenance of normal ovarian function requires the presence of two structurally normal X chromosomes, each with a specific site that maintains ovarian function. Premature ovarian failure is a group of X-linked genetic disorders, often associated with chromosomal rearrangements, translocations, or monosomy.
3. Immune Factors
This is not a common cause, but approximately 20% of patients have autoimmune diseases. These conditions may develop before the symptoms of ovarian dysfunction become apparent. Abnormal immune cells can cause ovarian damage or lead to autoimmunity when ovarian cells enter the bloodstream during ovulation, triggering an autoimmune response and producing autoantibodies against ovarian tissue. In 10%–69% of patients, anti-ovarian antibodies can be detected in the blood.
4. Infections
Mumps in prepubertal girls can lead to viral orchitis, and 2%–8% of patients with orchitis may develop premature ovarian failure. Women with a history of mumps have an increased risk of premature ovarian failure by nearly 10 times. Other infections can also cause premature ovarian failure by invading the ovaries, leading to inflammation and fibrosis, reducing the number of follicles, and ultimately resulting in ovarian failure.
5. Iatrogenic Factors
Any surgery involving the surrounding tissues of the ovaries may damage blood supply or cause inflammation, leading to premature ovarian failure. Surgeries that may cause this include hysterectomy, tubal ligation or removal, conservative or semi for endometriosis, wedge resection or puncture of the ovaries, cystectomy, or unilateral oophorectomy.
6. Metabolic Factors
Galactosemia is associated with premature ovarian failure, and women with this condition have a high rate of developing it. The primary reasons are:
① Accumulation of galactose in the body directly damages oocytes;
② Its metabolites cause damage to ovarian tissue;
③ Changes in the biological activity of gonadotropin molecules containing galactose lead to premature depletion of oocytes.
7. Autoimmune Premature Ovarian Failure
Approximately 20%–22% of patients with premature ovarian failure have autoimmune diseases in other organs, as these conditions can lead to endocrine organ (ovary) failure. For example, the most common thyroid disorders can cause premature ovarian failure.
8. Idiopathic Premature Ovarian Failure
This is premature ovarian failure with no apparent cause. It is characterized by normal chromosomes, no history of mumps, absence of anti-ovarian antibodies, no history of physical or chemical damage, and no metabolic disorders. It may be due to a lack of primordial germ cells or accelerated depletion of normal ovarian germ cells.
9. Ovarian Insensitivity Syndrome
This syndrome can lead to premature ovarian failure, as it causes elevated endogenous gonadotropin levels in the body.
10. Environmental and Psychological Factors
Smoking, alcohol consumption, insomnia, environmental pollution (e.g., excessive use of pesticides and heavy metals like cadmium, arsenic, and mercury; long-term or high-dose radiation exposure due to work, illness, or accidents), and strong psychological stress (e.g., chronic anxiety, depression, sadness, anger, fear) can all affect ovarian function, potentially leading to premature ovarian failure.
