Reactive oxygen species in follicular fluid may serve as biochemical markers to determine ovarian aging and follicular metabolic age.

Introduction: The aim of this study was to evaluate the role of oxidative stress in the process of ovarian aging.

Methods: Follicular fluid (FF) from two randomly selected sibling follicles was collected from women undergoing in-vitro fertilization and tested for hydrogen peroxide (H(2)O(2)) levels.

Results: Group A consists of seven women with whom each of the two sibling separate follicle yielded an oocyte that was later discordantly developed to a low- and top-quality embryo.

Influence of Campylobacter fetus subsp. fetus on ram sperm cell quality.

Campylobacter fetus subsp. fetus infection can occur in female sheep, causing infertility or abortion. Despite extensive research on the effect of these bacteria on female fertility, little research has been done on the influence of C.

[Acupuncture efficacy in osteoarthritis].

Osteoarthritis (OA) is the most common form of articular disorders, and is primarily a disorder of hyaline cartilage and subchondral bone, although all tissues in and around involved joints are hypertrophic. The etiology of OA is multifactorial, its prevalence is increasing and treatment is focused mainly on pain control and reduction of disability. One of the recently studied treatments, which were found to improve OA, is acupuncture.

Influence of visible light and ultraviolet irradiation on motility and fertility of mammalian and fish sperm.

Objective: The effects of visible light irradiation on sperm motility, fertility, and reactive oxygen species (ROS) formation were investigated and compared in ram and fish (tilapia).

Background Data: Low-energy visible light has previously been found to modulate various processes in different biological systems. In the literature, it is accepted that the first step following visible light irradiation is the formation of ROS by endogenous cellular photosensitizers.
