Cryopreservation is the advanced process of storing tissues, cells or organs at a very minimum and low temperature to preserve their viability. These cells or tissues can be revived by thawing under proper conditions and reused. In assisted reproductive technology we often have to freeze sperms. eggs or embryos.
Semen DNA Test
The detection and investigation in a sample of semen :
Let us assume that a man’s semen is alleged to be on a piece of fabric. To learn whether the cloth is stained by the suspect’s semen, DNA testing can be done.
The DNA tests of semen can take several days or several weeks before results are available, depending upon which techniques have been used by the lab (and which lab has done the DNA testing). DNA tests can show that the semen is not from the suspect. Or these tests can show that the DNA in the sperm is not detectably different from the suspect’s. But DNA testing can never prove with complete certainty that the semen is from the suspect.
A complete semen analysis measures the quantity and quality of the fluid released during ejaculation. It evaluates both the liquid portion, called semen or seminal fluid, and the microscopic, moving cells called sperm. It is often used in the evaluation of male infertility. A shorter version of this test checks solely for the presence of sperm in semen a few months after a man has had a vasectomy to determine whether the surgery.
Semen analysis test is a test that is done to estimate the amount and quality of sperm that is present in the semen. Apart from the number of sperm, the quality of the sperm and it’s different features are examined. This is the first and most basic Semen test that is done to help determine the fertility potential of a Male. Semen is the fluid like substance that is ejaculated from the male reproductive organ. This fluid contains the viable male gamete – the Sperm, proteins, enzymes and sugar substance mainly fructose.
