Anovulation is a condition in which the ovaries do not release an oocyte during a menstrual cycle. As a result, ovulation does not take place. Anovulation is a common cause of infertility and can be associated with various endocrine disorders.
Causes[edit]
Anovulation can be caused by a variety of factors, including:
- Polycystic ovary syndrome (PCOS)
- Hyperprolactinemia
- Hypothyroidism
- Hyperthyroidism
- Primary ovarian insufficiency
- Obesity
- Extreme weight loss or eating disorders
- Stress
Symptoms[edit]
The primary symptom of anovulation is irregular menstrual cycles or the absence of menstruation (amenorrhea). Other symptoms may include:
- Heavy menstrual bleeding or menorrhagia
- Infertility
- Acne
- Hirsutism (excessive hair growth)
- Weight gain
Diagnosis[edit]
Diagnosis of anovulation typically involves a combination of:
- Medical history and physical examination
- Blood tests to measure hormone levels, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, and thyroid hormones
- Ultrasound to examine the ovaries and endometrium
- Basal body temperature charting
Treatment[edit]
Treatment for anovulation depends on the underlying cause and may include:
- Lifestyle changes such as weight loss or gain, stress management, and dietary modifications
- Medications to induce ovulation, such as clomiphene citrate, letrozole, or gonadotropins
- Treatment of underlying conditions like thyroid disorders or hyperprolactinemia
- Surgery in cases of polycystic ovary syndrome (PCOS) or other structural abnormalities
Prognosis[edit]
The prognosis for anovulation varies depending on the cause. Many women with anovulation can achieve pregnancy with appropriate treatment. However, some underlying conditions may require long-term management.
