Sperm morphology refers to the shape of the sperm, which includes head size and head DNA content revealed by a nuclear color stain , the midpiece appearance and the structure of the tail. Sperm morphology is assessed during routine semen analysis that examines the sperm cells under a microscope. The semen analysis will also examine the motility movement ability and concentration of sperm present. Every male, fertile or infertile, has varying percentages of abnormally-shaped sperm. There are many factors that can lead to abnormally shaped sperm including increased testicular temperature, exposure to toxic chemicals, infection and genetic traits. The medical term for when a man has a large number of abnormally shaped sperm is teratozoospermia or teratospermia.

What If Your Semen Analysis Results Are Abnormal?
Inadequate production and quality of the sperm is one of the most common reasons for male infertility as it can lower the odds of one of the sperms fertilizing the egg for conception. According to the World Health Organization, the normal count of sperm is at least twenty million per ml of semen. Conception issues are associated with lower than forty million moving sperm in the ejaculate. Oligoospermia can occur because of a wide variety of reasons and contributing factors, such as infected semen, hormonal abnormalities, varicoceles enlargement of veins within the scrotum , infection in the prostate gland, use of anabolic steroids, damaged sperm ducts, alcohol abuse, cigarette smoking, toxic chemicals, drug abuse, heavy metal exposure, certain medications, and radiation. Even vaginal lubricants tend to be harmful to sperms. Recent researches claim that the heating of the testicles triggered by electromagnetic frequencies EMFs may also contribute to low sperm count. Therefore, habits such as keeping a cell phone in your pants pocket or a laptop on your lap are usually discouraged.

Sperm morphology — the size and shape of sperm — is one factor that's examined as part of a semen analysis to evaluate male infertility. Sperm morphology results are reported as the percentage of sperm that appear normal when semen is viewed under a microscope. Normal sperm have an oval head with a long tail. Abnormal sperm have head or tail defects — such as a large or misshapen head or a crooked or double tail. These defects might affect the ability of the sperm to reach and penetrate an egg.
Sperm morphology is a term used to describe the appearance shape and size of sperm. The shape of sperm is a reflection of proper sperm development spermatogenesis in the testicles. Men with defective sperm production may produce a high percentage of abnormal sperm. There are many factors that can lead to the formation of sperm with an abnormal morphology.
