The given test allows to determine the quantity of capable spermatozoids to fertilize oocytes.
The spermatozoid ability to fertilize oocyte has great significance in the natural cycle of fertilization, as well as in-vitro fertilization.
The oocytes is covered by viscose membrane, which leaks only correctly built, matured spermatozoids.
Only AVA CLINIC gives the possibility to determine sperm quality, what allowes to understand whether the spermatozoid is capable to penetrate to the viscose membrane of oocyte and to fertilize it.
Test operating principle:
There are receptors (protein substance) on the head of matured spermatozoid, which are responsible for the spermatozoid capability to identify and bind to the oocyte’s viscose mebrane. In case, if the first stage of sperm-oocyte fusion does not happened, the fertilization is impossible.
After that spermatozoid binded to the oocyte’s membrane, from its head substances (ferments), what dissolve the membrane and allow to the spermatozoid to penetrate, are released. There is spermatozoid-oocyte interaction’s reaction, when spermatozoid is able to fertilize oocyte.
These receptors are only on the head of matured spermatozoids. Precisely sperm function test will help to determine whether the spermatozoid is capable to bind to the oocyte and fertilize it.
This test is recommended if:
1. the pregnancy does not become for a long period of time (more than 2 years) and the reason of infertility is not disclosed.
2. You have had IVF cycle and a small amount or none of oocytes were fertilized.
3. In case if the results of ordinary sperm analysis do not allow to take the final decision for choosing the artificial fertilization method.
