What is Teratozoospermia? Causes & Treatments for Abnormal Sperm Shape

Teratozoospermia occurs when over 96% of sperm are abnormally shaped, causing fertility challenges. Diagnosed via semen analysis, it can stem from genetics, diabetes, or lifestyle factors. Treatments include antioxidants, IUI, IVF with ICSI, and in severe cases, sperm donation.

Key Takeaways

Causes of Teratozoospermia: Genetic, Lifestyle, and Medical Factors

Genetics, diabetes, smoking, malnutrition, and testicular issues are common causes. Age and cancer treatments like chemotherapy also contribute to abnormal sperm morphology. Addressing these root factors is critical for improving fertility outcomes.

Diagnosing Teratozoospermia: What a Semen Analysis Reveals

A semen analysis evaluates sperm shape (morphology), volume, and motility. If over 96% of sperm exhibit abnormalities, a diagnosis of teratozoospermia is confirmed, guiding further infertility treatment planning.

Improving Sperm Shape Naturally: Diet, Exercise, and Health Changes

Lifestyle modifications—such as quitting smoking, losing weight, adopting a nutrient-rich diet, and reducing alcohol/drug use—can enhance sperm morphology. Antioxidants like vitamin C and E are also recommended to combat oxidative stress.

IUI vs. IVF with ICSI: Best Fertility Treatments for Abnormal Sperm

Intrauterine insemination (IUI) and IVF with intracytoplasmic sperm injection (ICSI) are top solutions. ICSI involves selecting healthy sperm for direct egg fertilization, ideal for severe teratozoospermia cases.

When Sperm Donation Becomes a Viable Option for Teratozoospermia

If other treatments fail, sperm donation offers an alternative. This option is recommended when the male partner has no viable sperm or when teratozoospermia remains unresponsive to medical interventions.
