The causes of delayed menstruation in women include pregnancy,不良 lifestyle habits, emotional factors, medication effects, and polycystic ovary syndrome (PCOS), among others.

1. Pregnancy: If the fertilized egg successfully implants, it can lead to amenorrhea (absence of menstruation). If pregnancy is suspected, a timely blood test to measure human chorionic gonadotropin (hCG) levels can confirm it.

2.不良 Lifestyle Habits: Long-term不良 lifestyle habits may interfere with the regulatory function of the hypothalamic-pituitary-ovarian axis, leading to abnormal hormone secretion and consequently affecting the menstrual cycle, causing delayed menstruation.

3. Emotional Factors: Excessive mental stress, anxiety, or emotional instability may affect the normal secretion of hormones, leading to delayed menstruation.

4. Medication Effects: Taking progestin medications, short-term contraceptives, antibiotics, and other drugs may affect a woman's endocrine system, thereby causing menstrual cycle disorders.

5. Polycystic Ovary Syndrome (PCOS): PCOS can cause the ovaries to produce excessive amounts of androgens, affecting the normal secretion of estrogen and progesterone, thus leading to prolonged menstrual cycles.

When experiencing delayed menstruation, it is recommended to seek medical attention promptly so that a doctor can make a diagnosis and provide treatment based on the specific situation.
