Oligospermia
Oligospermia[edit | edit source]
Oligospermia, also known as oligozoospermia, is a male fertility issue characterized by a low sperm count in the ejaculate. It is one of the common causes of male infertility and can be influenced by various factors, including lifestyle, environmental, and genetic factors.
Definition[edit | edit source]
Oligospermia is defined by the World Health Organization (WHO) as a sperm concentration lower than 15 million sperm per milliliter of semen. This condition can be further classified into mild, moderate, and severe oligospermia based on the concentration of sperm present.
Causes[edit | edit source]
The causes of oligospermia can be broadly categorized into pre-testicular, testicular, and post-testicular factors:
Pre-testicular Causes[edit | edit source]
Pre-testicular causes are related to hormonal imbalances or systemic conditions that affect sperm production. These include:
Testicular Causes[edit | edit source]
Testicular causes are directly related to the testes and include:
- Varicocele
- Cryptorchidism
- Testicular cancer
- Genetic disorders such as Klinefelter syndrome
Post-testicular Causes[edit | edit source]
Post-testicular causes involve issues with sperm transport and include:
Diagnosis[edit | edit source]
The diagnosis of oligospermia typically involves a thorough medical history, physical examination, and semen analysis. A semen analysis will assess sperm concentration, motility, and morphology. Additional tests may include hormonal evaluations and genetic testing.
Treatment[edit | edit source]
Treatment for oligospermia depends on the underlying cause. Options may include:
- Lifestyle modifications such as weight loss and smoking cessation
- Medical treatments like hormone therapy
- Surgical interventions for conditions like varicocele
- Assisted reproductive technologies such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI)
Prognosis[edit | edit source]
The prognosis for men with oligospermia varies depending on the severity of the condition and the underlying cause. Many men with oligospermia can achieve pregnancy with appropriate treatment and interventions.
