Effectiveness of low level laser therapy for treating male infertility

Abstract

In half of the cases, the infertility of the couple is due to the disorder of the male fertility. The leading factors that cause male infertility are urogenital infections, disorders of the immune system, testicular and prostate pathology, as well as endocrine disorders.Low level laser therapy (LLLT) is a very effective physical therapy method, used in many areas of medicine, including obstetrics and gynaecology, andrology and urology; and it is recommended as an integral part of the complex treatment of infertility.The literature review showed that LLLT is beneficial in treating male infertility. Laser can significantly improve the survival, motility and speed of movement of spermatozoa. Laser therapy of patients with prostatitis and vesiculitis can eliminate infiltrative-exudative changes, improve reproductive and copulatory functions. Local illumination of red (635 nm) and infrared (904 nm) spectra should be combined with intravenous laser blood illumination (ILBI) of red (635 nm) and ultraviolet (UV) (365 nm) spectra.

Laser-Guided Sperm Selection: Optimizing the Reproductive Success Rate in Assisted Reproductive Technology

“…Creating real-time feedback mechanisms to assess the impact of laser stimulation on sperm motility may allow for dynamic modifications during the operation. Specialists could fine-tune parameters to get the best potential motility improvement without causing injury by obtaining immediate information on the reaction of sperm to laser stimulation [ 31 ]. Integrating analytical abilities into LAISS devices may allow for a more in-depth review of treatment results over time.…”

Photo Stimulation of Seminal Doses with Red LED Light from Duroc Boars and Resultant Fertility in Iberian Sows

“…Previous studies have pointed out the sensitivity of sperm cells to light exposure. Differences between species, type of light, intensity and duration of the illumination used in these studies have produced controversial outcomes [1][2][3]. In pigs, a red LEDbased photostimulation procedure (10 min illumination, 10 darkness and 10 illumination) increased the achievement of in vitro capacitation and subsequent progesterone-induced acrosome reaction [4].…”

Regarding the efficacy of low-level laser therapy in infrared spectrum in male secretory infertility

“…Медикаментозное лечение секреторной и аутоиммунной форм мужского бесплодия в большинстве случаев недостаточно эффективно [12], в связи с чем возрастает потребность в использовании и совершенствовании методов вспомогательных репродуктивных технологий. Однако они являются весьма дорогостоящими, а их результативность не превышает 30 % [13].…”

“…Новым перспективным методом лечения секреторной и аутоиммунной форм мужского бесплодия является низкоинтенсивная лазерная терапия (НИЛТ) органов мошонки [12,14]. Однако в отечественной и зарубежной литературе мы встретили лишь единичные публикации, посвященные изучению ее влияния на патологическую ФДНКС и/или показатель MAR-теста.…”
