Morphology sperm count

But seriously, the judgment of the shape of sperm under the microscope is what determines the morphology score. Numbers in italics are what "normal" values should be. Chemical and Biochemical Semen Characteristics Semen acid-base balance pH The pH of semen is measured using a specially treated paper blot that changes color according to the pH of the specimen that it is exposed to. A new test, due for release to laboratories in early is able to determine biochemically if sperm have been damaged by any cause within the male reporiductive tract, making them incapable of fertilizing the egg. Zona Pellucida Binding Tests When a normal sperm binds to the zona pellucida of a healthy egg, the sperm normally undergoes an "acrosome reaction" that releases components that lead to normal fertilization. However, if all sperm are abnormal, it does mean that conceiving may take longer and in many cases, may need to be assisted with insemination or In Vitro Fertilization. The only way to differentiate between complete and partial testicular failure is by doing multiple testicular micro-biopsies to sample different areas of the testes and send them for pathological examination.

Smoking, obesity, and excess alcohol intake has been linked to low sperm count. Uncover problems in sperm DNA which could be keeping you from pregnancy. Some part of ejaculation could be lost, bacterial contamination could happen and the acid vaginal pH could be detrimental for sperm motility. There are two methods for performing a semen analysis: Motility What Is It: Sometimes there are lifestyle modifications that can help.

Strict morphology is a useful test to perform with couples that have unexplained infertility, even if the semen analysis and non-strict morphology are otherwise normal. Total motility refers to any movement, while progressive motility refers to forward movement in either a line or in a large circle. These highly intricate cells have a very specialized function, unlike any other cells in the body. Azoospermia may be caused by a duct problem, a hormonal imbalance, or a problem with the testes.
