If you were recently told by your doctor that you have abnormal sperm morphology, you probably have more questions than answers: What exactly does this mean? How does this affect my fertility? What can I do about it? Morphology refers to the shape of your sperm, or what it looks like under a microscope.

Sperm Morphology: What Is It and How Does It Affect Fertility?
An abnormal sperm count may also indicate an underlying health condition. A normal sperm count ranges from 15 million sperm to more than million sperm per milliliter mL of semen. Anything less than 15 million sperm per milliliter, or 39 million sperm per ejaculate, is considered low. A low sperm count is often referred to as oligospermia. A high, or above average, sperm count is over million sperm per millimeter.
What If Your Semen Analysis Results Are Abnormal?
Patient charts were reviewed with men contacted and administered an Institutional Review Board IRB -approved telephone questionnaire to ascertain outcomes. After a median follow-up time of 2. Strict morphology should not be used to predict fertilization, pregnancy, or live birth potential. Semen analysis is a critical tool in the assessment of the infertile male; however, the importance of sperm shape, or morphology, is controversial. The ability of sperm morphology to predict in vitro reproductive outcomes was first proposed by Kruger et al.
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.
