Abnormal Sperm Shape

Teratospermia, also known as abnormal sperm morphology, is a condition where most sperm in a semen sample have an irregular shape. Sperm morphology is a crucial factor in fertility as it affects the sperm’s ability to fertilize an egg. In teratospermia, the unusual shape of the sperm may hinder its movement and reduce the likelihood of successful fertilization.

What Is Abnormal Sperm Shape?

Sperm morphology refers to the size and shape of sperm cells. Normal sperm have a defined oval head and a long tail that enables movement. In teratospermia, sperm may have multiple tails, irregular head shapes, or other structural abnormalities that impact their function.

Causes of Teratospermia

The causes of teratospermia can be multifactorial, including genetic factors, lifestyle choices such as smoking and excessive alcohol consumption, environmental toxins, and health issues like obesity, varicocele, and hormonal imbalances. Certain medications and exposure to radiation or heat can also affect sperm morphology.

Symptoms and Detection

Typically, there are no outward symptoms of teratospermia. The primary indication is difficulty in achieving pregnancy. Diagnosis is made through a semen analysis, where the shape and structure of the sperm are examined under a microscope.

Diagnosing Teratospermia

A detailed semen analysis is essential for diagnosing teratospermia. This test evaluates the percentage of sperm with normal shapes in a sample. Additional testing may include physical examinations, hormone tests, and genetic screenings to identify potential underlying causes.

Treating Abnormal Sperm Shape

Treatment strategies for teratospermia focus on the underlying cause. Lifestyle modifications like improving diet, exercising, and avoiding harmful substances can be beneficial. Medical treatments may include hormone therapy or surgery for conditions like varicocele. Assisted reproductive technologies, such as IVF and ICSI, offer effective solutions for couples facing fertility challenges due to teratospermia.

Prevention Strategies

Preventive measures for teratospermia include maintaining a healthy lifestyle, avoiding excessive heat to the testicles, reducing stress, and avoiding exposure to environmental toxins. Regular health check-ups and early intervention for any identified issues can help in maintaining better sperm health.


Teratospermia can be a significant obstacle in the journey toward parenthood, but it’s not an insurmountable one. With proper diagnosis, tailored treatments, and advancements in assisted reproductive technology, many men with abnormal sperm morphology can still father children and achieve their family goals.
