Understanding Asthenoteratozoospermia: Causes, Diagnosis & Fertility Outlook

Asthenoteratozoospermia is a combination of two sperm abnormalities:

• Asthenozoospermia: Reduced sperm motility (movement).
• Teratozoospermia: Abnormal sperm shape and size.

While the exact cause often remains unknown, various lifestyle, environmental, and medical factors can contribute to this condition. With proper evaluation and case selection, both medical and microsurgical treatments have proven effective in managing this condition.

What Causes Asthenospermia?

For sperm to successfully reach and fertilize the egg, progressive motility is essential. Several contributing factors to reduced sperm motility include:

• Chronic stress and anxiety
• Medical conditions like diabetes, obesity, or hypothyroidism
• Varicocele (enlarged veins in the scrotum)
• Poor dietary habits and excessive heat exposure
• Smoking and heavy alcohol use
• Testicular cancer or infections
• Underlying genetic conditions

Despite these known factors, in many cases, the root cause of asthenozoospermia remains unclear, emphasizing the need for individualized evaluation.

Is Asthenoteratozoospermia Curable?

A complete andrological evaluation is essential to determine the cause and plan the best treatment. Depending on the underlying issue, several solutions may help:

• Lifestyle changes – Regular exercise, healthy weight, reduced heat exposure, and quitting smoking/alcohol
• Use of antioxidant and fertility-boosting supplements
• Hormonal therapy – For cases with hormonal imbalances (e.g., FSH or hCG)
• Microsurgical procedures – Especially for varicocele or other testicular conditions

Can You Get Pregnant with Teratozoospermia?

Yes, pregnancy is possible. However, having a high percentage of abnormally shaped sperm may be associated with reduced fertility. In many cases, teratozoospermia occurs alongside low motility or sperm count, which can further complicate natural conception. Assisted reproductive technologies like ICSI (Intracytoplasmic Sperm Injection) can help overcome these barriers.

Can Poor Quality Sperm Fertilize an Egg?

Ideally, healthy sperm should fertilize the egg to increase the chances of a healthy embryo. However, even sperm with damaged DNA can fertilize an egg, which may lead to complications during embryo development or result in miscarriage. Therefore, thorough evaluation and sperm quality enhancement strategies are recommended for couples trying to conceive.
