Researches from the USA and Italy developed a new technique, so called 3D sperm evaluation which enables them to assess sperm motility with precision. It is very important for the selection of spermatozoa used in IVF+ICSI procedures. The essence of the innovation is embryologists can watch spermatozoa moving in real time. The researchers are going to perfect the 3D technique so that embryologists might select only the superior spermatozoa.
Intracytoplasmic sperm injection is applied to treat severe cases of male infertility (aspermia, asthenozoospermia, immunologic factor and etc.). It presupposes a selection of a spermatozoon which will be inserted into the cytoplasm of an egg cell.
At the moment embryologists select spermatozoa by studying a sperm sample under a microscope and evaluating their quality by eye. However, IVF clinics can use a PICSI dish which helps select mature spermatozoa on the basis of their ability to bind to hyaluronic acid covering the bottom of the dish.
