The sperm sample is observed under the microscope and studied in a medical lab. Poor sperm development can lead to teratospermia (also known as abnormal sperm morphology or poor shape) a condition characterized by the presence of a large percentage of sperm with abnormal shape in a man’s ejaculate. This abnormal sperm morphology can negatively impact the chances of conception. During this assessment, the sperm is examined under a microscope to determine the ratio of normal to abnormal sperm. Sperm morphology is measured by a percentage of “normal forms,” sometimes abbreviated to NF, or “normal sperm.” It’s important to note that even healthy, fertile men will produce a high percentage of abnormal sperm.

Normal sperm have an oval head with a long tail.

2021-01-23 Globozoospermia, or round headed sperm condition, is an abnormal sperm morphology that indicates either there is an absence of the acrosome or the sperm is missing inner parts of its head responsible for “activating” or turning on the egg and starting the fertilization process. To assess sperm morphology, the sperm are examined under a microscope and the percentage of abnormally shaped sperm is estimated. It is important to know that all men produce abnormal sperm and as many as half of the sperm in a “normal” semen sample are abnormally shaped. Sperm morphology is assessed using one of 2 sets of characteristics. mean sperm concentration in group I was 63.3 ± 42.8 X 106/ml (mean ± standard deviation) and in group II, 83.3 ± 57.8 X 106/ml (no significant difference) (Table 1).
