Photobiomodulation in Complex Female Infertility Profile: A Case Report with 12-Month Follow-Up and Review of Current Mechanism in Reproductive Photomedicine

Female infertility from polycystic ovarian syndrome (PCOS) and endometriosis poses a challenge for both clinicians and women who are trying to conceive. The present clinical single case report aimed to evaluate the efficacy of multiple wavelengths of red and near-infrared (NIR) laser photobiomodulation (PBM) for increasing the potential of fertility in a woman with PCOS, endometriosis and low ovarian reserve. The observations helped to inform and establish the following: (1) any adverse effects; (2) the possibility of producing an effective PBM protocol; and (3) a healthy live birth. The case report concerns a female who failed to conceive naturally beyond five years and had experienced one unsuccessful IVF cycle. Methods: Case report of one female subject with infertility issues, which included failure to conceive naturally beyond five years. Previous conditions were recorded and then compared with outcomes from after the patient received a course of PBM treatments. PBM treatments were given at weekly and/or at two-week intervals over a 5-month period during the follicular stage of the menstrual cycle, using IR and NIR wavelengths between 600 and 1000 nm. Results: After five months a spontaneous conception was achieved. The case resulted in a full-term pregnancy and the birth of a healthy baby. Improvements in reproductive health outcomes in this case give reason to suggest that PBM helped to alleviate PCOS and endometriosis which could have been associated with a low ovarian reserve. Conclusions: The case report indicates that a multiwavelength of red and NIR-PBM laser therapy could have positively contributed to a healthy live birth in a female diagnosed with PCOS, endometriosis and a low ovarian reserve. Extensive studies with large data are warranted to validate our PBM dosimetry and treatment protocols to assess the potential impact of PBM for treating endometriosis and PCOS. Subsequently, to understand the genetic and phenotype biomarkers would be an important step further to standardise a range of PBM light dosimetry.
