The spermatozoa in ejaculate need to have gone through a process known as sperm capacitation in order to obtain the ability to fertilise. This happens naturally in the female reproductive system and techniques in order to make it happen in the laboratory have been undergoing development for many years. […]

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. […]
