How can the best spermatozoon for fertilising an egg be selected?

Selection of the spermatozoon capable of fertilising an egg and generating a viable embryo is a subject that has been covered in a great number of studies aiming to provide this question with an answer.
Although assisted reproduction techniques have been used for dealing with fertility issues for many years, there is still room for improvement in terms of the results obtained. First of all, we need to fully determine the role of the spermatozoon because it tends to be thought of simply as the transporter of the father’s genetic material with no impact on later development. This idea has already been turned on its head and sperm does not only play a role in the fertilisation process. An abnormal spermatozoon can give rise to abnormal embryos and can even influence implantation failure. […]

Using Magnetic Fields to Select Healthy Sperm: MACS (Magnetic Activated Cell Sorting)

It is well known that having the best possible sperm quality is important to the success of assisted reproduction techniques. To achieve this, the lab has to improve sperm quality based on its motility and morphology, selecting the sperm that is considered to be the best.
However in every ejaculate sperm with abnormal membranes are found, which are programmed to “die”. This process is called apoptosis, or programmed cell death.   Approximately 20% of sperm in subfertile patients are  thought to be in the process of “celular death”. […]
