What is PRP treatment?

PRP treatment (autologous platelet-rich plasma) is the treatment of using your own blood plasma enriched with platelets, which contain a large number of growth factors. Growth factors play a pivotal role in the regeneration of tissues and the activation of cell growth. When highly concentrated growth factors are injected into damaged or affected tissue, then regenerative processes may be activated.


How can PRP treatment rejuvenate the endometrium?

PRP may be very helpful in cases of persistently thin endometrium before the embryo(s) are transferred inside the womb. The presence of chronic inflammation and scarring of the endometrium can make embryo implantation difficult in both natural pregnancy and IVF cycles. Application of the PRP injections aims to eliminate inflammation and promote the activity of the progesterone receptors that stimulate healthy growth of the endometrium.


What are the stages of PRP treatment?

PRP treatment is carried out in several stages. Initially, a few millilitres of peripheral blood are taken from the woman. Subsequently, this blood is placed in a device and centrifuged, which helps divide the blood into its different components. Red blood cells and leukocytes are removed, while platelets are maintained and concentrated. This technique allows us to obtain platelet-rich plasma with platelet concentration approximately five times higher than in peripheral blood.

The whole process takes minutes and the infusion of the PRP in the endometrium is brief and pain free.


How safe is PRP treatment?

No side effects of PRP therapy have been reported. As the woman’s own blood is used to produce the platelet-rich plasma, no allergic reactions are expected.
The application of PRP-injections can work differently for different women.
