Intravascular Laser Irradiation of Blood Use in Poor Ovarian Responders

The Effects of Intravascular Laser Irradiation of Blood on Reproductive Outcomes in Poor Ovaria n Responders Undergoing in Vitro Fertilization Cycles

The aim of this study was to investigate the effects of intravascular laser irradiation of blood on outcomes of in vitro fertilization cycles in poor ovarian responders.

Intravascular laser irradiation of blood (ILIB) with He-Ne laser (632.8nm) has been applied on many organs and on the hematologic and immunologic system. Quite a number of both animal and human experiments have demonstrated that ILIB has a wide range of effects, including biostimulation, analgesia, antiallergic effects, immunomodulation, vasodilatation, antihypoxic, anti-oxidant, anti-aging and anti-inflammatory effects.

Poor ovarian responders (PORs) defined as poor or no response to ovarian stimulation had poor prognosis in assisted artificial technique (ART), which is a great challenge in in vitro fertilization (IVF) cycles. Previous studies showed that treatment with anti-oxidants could improve the outcomes of the poor ovarian responders; however, the effect is limited. Since ILIB has anti-aging, anti-oxidant and anti-inflammatory effects, the investigators hypothesize that ILIB may improve ovarian function and oocyte quality in PORs. Therefore, the investigators attempt to explore the effects of ILIB on the IVF outcomes in women with poor ovarian response.
