A semen analysis microscopically looks at a man’s semen checking for abnormalities. A semen analysis can come back abnormal if the semen volume, sperm count, sperm morphology (shape) or sperm motility (ability to move) do not meet medical standards. Once the egg is fertilized, abnormal sperm morphology does not appear to influence blastocyst development or blastocyst morphology. Even with severe teratozoospermia, microscopy can still detect the few sperm cells that have a "normal" morphology, allowing for optimal success rate. 2020-09-30 2019-11-11 2016-07-28 2021-03-29 The Abnormal Sperm Production or any clinical defects of the male reproductive system may lead to missing of these characteristics in the sperms, which in turn, can make them sterile or infertile to a certain level.
