Changes in sperm morphology are thought to reflect alterations in the process of spermatogenesis. Because treatment-induced changes in sperm morphology do represent an adverse effect on spermatogenesis, these abnormalities are viewed as toxic effects in the risk assessment process (Boekelheide 1988; Boockfor and Blake 1997; Plassmann and Urwyler 2001 ). Sperm with abnormal morphology may have an abnormal head, mid-piece and/or tail. Thus, there may be the following abnormalities: Head alterations: spermatozoa without head (pinhead), small head, amorphous, round, elongated, large head (globozoospermia), pear-shaped (pyriform), with large acrosome, with small acrosome, without acrosome, with many vacuoles, with large vacuoles or with two heads.

The head shape is important 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. ‌Sperm morphology refers to the form or shape of sperm, the male reproductive cell. Sperm of various plant and animal species differ from one another, sometimes in surprising ways. The sperm of Sperm morphology refers to the size, shape and appearance of a man’s sperm, which when abnormal can decrease fertility and make it more difficult to fertilize the woman’s egg.

These may not be professionally administered drugs, but they have been used to improve sperm health for centuries, including sperm morphology. You want at least 4% normal sperm morphology (shape).

To report sperm morphology properly, the sperm need to be stained , and the shape of each individual sperm ( for at least a total of 100 sperm) tallied. The technicians don’t have the ability to follow this, so they just take shortcuts.

Morphology means the sperm’s structure or shape, which is ideally a smooth oval head; a well-defined acrosome, or cap, that covers 40–70% of the head; and a long tail with no visible abnormalities.
