The role of antioxidants in male infertility

Whilst several causes of male infertility have been recognised, in the majority of men the precise mechanism remains unknown. Many studies of such idiopathic cases at the molecular level have highlighted the significant role of “Oxidative Stress”. This entails a state of imbalance between reactive oxygen species (ROS), aka “free radicals”, and antioxidants as an […]

Cryopreservation of sperm

In men with azoospermia (complete absence of sperm in the semen), surgical sperm extraction from the testis or epididymis might be their only option. Recent research has also shown that in men with sperm present in their semen, but of very low concentration and quality, surgically extracted sperm directly from the testicle is often completely […]

Healthier DNA of testicular sperm

Research presented at the 2019 European Association of Urology Congress in Barcelona revealed that the DNA of sperm extracted from the testicles of infertile men might be just as healthy as the sperm found in the ejaculate of fertile men. The research could have implications for improved treatment of male infertility. This research supports past understanding of […]

Varicocele and infertility

35-40% of men undergoing infertility evaluation have a varicocele. Although the damage caused might be multifactorial and the exact mechanism is not fully understood, testicular hyperthermia is probably a significant factor. Today, treatment has evolved into a variety of techniques. There is a consensus between the European Association of Urology (EAU) and American Society for […]

Surgical Sperm Retrieval at the time of Vasectomy Reversal

England and Wales have the highest divorce rate in the EU with 42% of all marriages failing. 5% of men who had a vasectomy request reversal at a later date. The European Association of Urology (EAU) issued the following strong recommendations: Microsurgical vasectomy reversal is a low-risk and (cost-) effective method of restoring fertility. Surgical […]
