Summary
Varicocele is linked to increased sperm DNA fragmentation and oxidative stress in infertile men. Varicocele repair surgery can decrease this DNA damage, improving sperm integrity.
Area of Science:
- Reproductive Medicine
- Andrology
- Urology
Background:
- Varicocele is a common cause of male infertility.
- It is associated with impaired sperm quality and function.
- Oxidative stress plays a significant role in varicocele-related infertility.
Purpose of the Study:
- To review the scientific literature on the association between varicocele and sperm DNA fragmentation.
- To investigate the impact of varicocele on seminal oxidative stress.
- To evaluate the effect of varicocele repair on sperm DNA integrity.
Main Methods:
- Systematic literature review.
- Analysis of studies involving men with varicocele and infertility.
- Assessment of outcomes related to seminal oxidative stress and sperm DNA fragmentation.
Main Results:
- Men with varicocele exhibit elevated levels of reactive oxygen species and sperm DNA damage.
- Defective spermatogenesis and diminished seminal antioxidant capacity are observed in these patients.
- Varicocele repair leads to a reduction in sperm DNA fragmentation.
Conclusions:
- Varicocele is significantly associated with sperm DNA damage, likely due to varicocele-induced oxidative stress.
- This sperm pathology may be a direct consequence of the varicocele.
- Varicocelectomy demonstrates a beneficial effect on sperm DNA integrity, supporting its role in improving sperm quality.

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
02:08Gene Conversion
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
02:04Fixing Double-strand Breaks
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...
02:25Overview of DNA Repair
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.
