Oligoovulation

Oligoovulation is a medical condition characterized by infrequent or irregular ovulation. It is a common cause of subfertility and infertility in women. Oligoovulation is often associated with polycystic ovary syndrome (PCOS), a hormonal disorder causing enlarged ovaries with small cysts on the outer edges.

Causes

The primary cause of oligoovulation is polycystic ovary syndrome (PCOS). Other potential causes include hypothalamic dysfunction, hyperprolactinemia, and ovarian insufficiency. Certain lifestyle factors, such as stress, excessive exercise, and being underweight or overweight, can also contribute to oligoovulation.

Symptoms

The main symptom of oligoovulation is irregular menstrual periods. Women with this condition may also experience amenorrhea (absence of menstrual periods), oligomenorrhea (infrequent menstrual periods), or menorrhagia (heavy menstrual periods). Other symptoms can include hirsutism (excessive hair growth), acne, and weight gain.

Diagnosis

Diagnosis of oligoovulation typically involves a physical examination, medical history, and blood tests to measure hormone levels. An ultrasound may also be used to examine the ovaries for cysts.

Treatment

Treatment for oligoovulation often involves lifestyle changes, such as maintaining a healthy weight and reducing stress. Medications, such as clomiphene and metformin, may also be prescribed to stimulate ovulation. In some cases, surgery may be recommended to remove cysts from the ovaries.
