A blighted ovum, also known as anembryonic gestation, is a type of early pregnancy failure where the embryo either fails to develop or is reabsorbed. It is a common cause of miscarriage, particularly in the first trimester.

Definition

In a blighted ovum, the gestational sac develops, but the embryo does not form or stops growing very early and is reabsorbed. It is often considered a type of missed miscarriage.

Causes

While the exact cause is often unknown, potential factors include:

• Chromosomal abnormalities
• Poor quality sperm or egg
• Uterine abnormalities
• Hormonal factors

Diagnosis

A blighted ovum is typically diagnosed through:

• Transvaginal ultrasound showing an empty gestational sac
• HCG (human chorionic gonadotropin) blood tests showing abnormal levels

Symptoms

Symptoms may include:

• Vaginal spotting or bleeding
• Cramping
• Decline in pregnancy symptoms

Treatment

Treatment options include:

• Expectant management, allowing the body to pass the tissue naturally
• Medical management with medication
• Surgical options like dilation and curettage (D&C)

Coping and Support

Dealing with a miscarriage can be emotionally challenging. Support may be found through:

• Counseling
• Support groups
• Open communication with healthcare providers
