Teratozoospermia – Definition, Causes and Treatment Options
1. Definition
Teratozoospermia (also known as teratospermia) is a medical condition in which a man has a high number of abnormally shaped sperm in his semen. This condition is one of the three key factors commonly checked during a sperm health test, along with how many sperm are present and how well they move. In this condition, the shape or structure of the sperm – called morphology – is not normal, which can make it harder for the sperm to fertilise an egg.
2. Key Takeaways
- Teratozoospermia is a male fertility condition.
- It refers to a situation where a high number of sperm in a man’s sample are misshapen or not formed correctly.
- Abnormal sperm may struggle to reach or fertilise the egg.
- It can reduce the chances of natural conception.
- To detect this condition, doctors carry out a laboratory test called a semen analysis.
- Depending on what’s behind it, the issue may go away over time or it might continue long term.
- Treatments and assisted reproductive techniques are available.
3. Why Teratozoospermia Diagnosis is Important for Fertility
-
Understanding Male Fertility
For a man to be fertile, sperm must not only move well but also have a proper structure. Teratozoospermia directly affects sperm shape, which impacts their ability to penetrate and fertilise an egg.
-
Impact on Conception
These might include problems with the shape of the head, middle section or tail, which can interfere with their ability to:
- Swim efficiently to the egg
- Attach or penetrate the egg’s outer layer
- Carry genetic material properly
Even when count and movement are within healthy limits, abnormal shape alone can prevent successful fertilisation.
-
Helps Determine Best Treatment Options
Knowing the level of abnormal sperm can guide doctors in choosing the right fertility treatment. Options may include:
- Lifestyle changes
- Medication or hormone therapy
- Assisted reproduction like ICSI (Intracytoplasmic Sperm Injection), which helps even poorly shaped sperm fertilise an egg or advanced sperm selection technologies.
-
A Clue to Underlying Health Issues
In certain instances, teratozoospermia can be an indicator of more extensive underlying health conditions, such as:
- Hormonal imbalances
- Genetic conditions
- Infections
- Exposure to toxins, heat or radiation
Diagnosing it can therefore help in improving general male health, not just fertility.
4. Example Case Study
A man, aged 33, and his partner had been trying for a baby for over a year. A routine semen analysis showed that he had teratozoospermia, with only 2% of his sperm shaped normally. Although his sperm count and motility were good, the low morphology made conception difficult.
His doctor advised lifestyle changes: cutting down on alcohol, quitting smoking and improving his diet. After about six months, follow-up testing showed that his sperm shape had improved. When natural conception didn’t happen, the couple used ICSI with sperm selection methods. They are now expecting their first child.
5. FAQs
Q1: What causes teratozoospermia?
Causes may include genetics, infections, exposure to harmful chemicals, smoking, alcohol, poor diet or overheating of the testicles.
Q2: Can a man with teratozoospermia get his partner pregnant naturally?
Yes, but it may take longer. The chances depend on how many sperm are shaped normally and other fertility factors.
Q3: Is teratozoospermia permanent?
Not always. In some men, it improves with lifestyle changes or treatment. Others may need fertility help long-term.
Q4: How is teratozoospermia diagnosed?
Through a semen analysis in a fertility clinic or andrology laboratory, where the shape, count and movement of sperm are checked.
Q5: What treatments are available?
Treatments may include vitamin supplements, lifestyle changes, hormone therapy or assisted reproductive technologies like IVF and ICSI.
Q6: Is it dangerous to the baby if sperm are abnormally shaped?
Abnormal sperm shape can affect fertilisation but doesn’t usually cause harm to the baby if fertilisation occurs successfully.
6. Call to Action
If you or your partner are having trouble conceiving, it’s important not to ignore the male side of fertility. A simple semen test can uncover issues like teratozoospermia early, allowing for timely treatment or support.
Speak to a fertility specialist or GP today to get tested. Making even modest improvements to one’s daily habits, diet and routine can bring meaningful changes to sperm quality.
