Subfertility

Subfertility, also known as reduced fertility, refers to a condition where a person or couple has difficulty conceiving a child, but not necessarily an absolute inability to conceive.

Definition and Prevalence

Subfertility is a common issue affecting millions of people worldwide. According to the World Health Organization (WHO), approximately 15% of couples of reproductive age experience subfertility. The condition can affect both men and women, and in many cases, it is a combination of factors that contribute to subfertility.

Causes of Subfertility

There are several potential causes of subfertility, including:

Symptoms and Diagnosis

The primary symptom of subfertility is difficulty conceiving a child after one year of regular, unprotected intercourse. In some cases, there may be additional symptoms, such as:

Diagnosis of subfertility typically involves a comprehensive medical evaluation, including:

  • Medical history and physical examination
  • Hormone level testing (e.g., follicle-stimulating hormone (FSH), luteinizing hormone (LH), or testosterone)
  • Semen analysis in men
  • Imaging studies, such as ultrasound or hysterosalpingography (HSG) to evaluate the reproductive organs
  • Laparoscopy or other surgical procedures to assess tubal patency and ovarian function

Treatment Options

Treatment for subfertility depends on the underlying cause(s) and may involve:

  • Medications, such as fertility drugs (e.g., clomiphene citrate or letrozole) to stimulate ovulation or improve sperm quality
  • Surgical procedures, like tubal repair or varicocele correction
  • Assisted reproductive technologies (ART), including in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), or donor egg/sperm programs
  • Lifestyle modifications, such as weight management, stress reduction, and smoking cessation

Prognosis and Outlook

The likelihood of successful treatment and conception varies depending on the individual or couple's specific circumstances. With proper diagnosis and treatment, many people with subfertility are able to conceive and have a healthy pregnancy.
