Description

  • > 50%

Clinical significance

  • Morphology is the study of shape, size and appearance of the sperm cells. The analysis evaluates the structure of the sperm. More than 50 % cells examined should be normal in size, shape and length. The more abnormal sperm that are present, the greater the likelihood of infertility
  • 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. However, having a large percentage of misshapen sperm is not uncommon
  • Abnormal sperm Morphology is termed as Teratozoospermia, the causes of which may be increased testicular temperature, infection and genetic traits. Abnormal morphology includes Giant sperm, Micro sperm, double head, absent neck, short tail, double tails etc
