Male factor is responsible for 40-50% of infertility cases, contributing equally as a female factor. Oxidative stress has now emerged as one of the major causes of unexplained male infertility, as it leads to increased risk of Deoxyribonucleic acid (DNA) fragmentation, decreased sperm motility, concentration and abnormal morphology. Though a certain amount of reactive oxygen species (ROS) activity is essential for normal functioning of sperms, an excess lead to pathological effects on semen parameters, ultimately resulting in male sub-fertility or infertility. Furthermore, oxidative stress affected sperm cells with damaged DNA result in increased risk of birth defects, neuropsychiatric problems and cancers in off-springs of such fathers due to increased risk of de-novo mutations in the germline and post-fertilization. Hence, present review helps in highlighting the facts about ROS, their production, physiological functions and pathological effects on sperm dysfunction and DNA damage, leading to male infertility.

In 50% of all infertility cases, the male is subfertile or infertile, however, the underlying mechanisms are often unknown. Even when assisted reproductive procedures such as in vitro fertilization an...
Seminal plasma is a key biological fluid that modulates sperm function in the reproduction process. However, its role in sperm biotechnologies is scarce in poultry. The aims of the present study were ...
Zinc (Zn) is necessary for the normal function of the male reproductive system and spermatozoa. Although influences of zinc deficiency on impaired spermatogenesis and male infertility have been widely...

What is the topic of this review? Within this review, the role of reactive oxygen species in cellular homeostasis, physiology and pathophysiology is discussed. What advances does it highlight? The rev...
All couples planned for IVF will be asked to participate. After information and received informed consent they will be randomized into two groups. At the time for ovum pick up during an I...
The overall objective of this clinical study is to determine if smokers who switch from their usual high reactive oxygen and nitrous oxide species (ROS/NOS) products to a low ROS/NOS produ...
Men are recruited to collect seminal plasma samples and serum samples from men with azoospermia, men receiving medical treatment of infertility and men attending semen analysis. MicroRNA (...
Identify, by Lipidomics approaches, biochemical markers of fertility / infertility in sperm and seminal plasma linking the success or failure of the artificial insemination (IUI)
The aim of the study is to investigate the effect of inhaled apocynin on ROS (reactive oxygen species) and NOS (reactive nitrogen species) synthesis in 10 nonsmoking mild asthmatics. Effec...
Proteins found in SEMEN. Major seminal plasma proteins are secretory proteins from the male sex accessory glands, such as the SEMINAL VESICLES and the PROSTATE. They include the seminal vesicle-specific antigen, an ejaculate clotting protein; and the PROSTATE-SPECIFIC ANTIGEN, a protease and an esterase.
The inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male sterility is permanent infertility.
Molecules or ions formed by the incomplete one-electron reduction of oxygen. These reactive oxygen intermediates include SINGLET OXYGEN; SUPEROXIDES; PEROXIDES; HYDROXYL RADICAL; and HYPOCHLOROUS ACID. They contribute to the microbicidal activity of PHAGOCYTES, regulation of signal transduction and gene expression, and the oxidative damage to NUCLEIC ACIDS; PROTEINS; and LIPIDS.
An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).
A form of male HYPOGONADISM, characterized by the presence of an extra X CHROMOSOME, small TESTES, seminiferous tubule dysgenesis, elevated levels of GONADOTROPINS, low serum TESTOSTERONE, underdeveloped secondary sex characteristics, and male infertility (INFERTILITY, MALE). Patients tend to have long legs and a slim, tall stature. GYNECOMASTIA is present in many of the patients. The classic form has the karyotype 47,XXY. Several karyotype variants include 48,XXYY; 48,XXXY; 49,XXXXY, and mosaic patterns ( 46,XY/47,XXY; 47,XXY/48,XXXY, etc.).
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
