Sperm morphology refers to the size and shape of sperm; abnormal sperm is one possible cause of male infertility because sperm may have difficulty travelling to the egg or may be unable to fertilise it once there. There are a number of treatment options available depending on the cause of abnormal sperm.

Abnormal sperm morphology can occur when men are exposed to toxic chemicals such as drugs, cigarettes or household products; increased testicular temperature, often due to restrictive clothing or a varicose vein in the scrotum; or genetic inheritance.
For some men, reversing abnormal sperm morphology is as simple as switching from briefs to boxers, avoiding drugs, cigarettes and common chemicals, and avoiding prolonged periods of sitting that cause the testicles to stay close to the body and heat up.
A urologist can remove a varicose vein in the scrotum with surgery. However, many men with abnormal sperm morphology require fertility treatment in order to impregnate a partner; intracytoplasmic sperm injection (ICSI) and artificial insemination are two popular options, according to BabyCenter.com.
Intracytoplasmic Sperm Injection
Intracytoplasmic sperm injection (ICSI) is a process whereby sperm are directly injected into the egg outside of the womb, according to BabyCenter.com; the egg is then implanted into the uterus.
According to Oregon State University, it may take up to 18 months to see improved sperm morphology and only about half of all men see results.
