Medical therapy for spermatogenic failure

Medical therapy for spermatogenic failure.

Medical treatment of men with primary spermatogenic failure remains largely ineffective in contrast to those with secondary testicular failure. Treatment has been attempted with a multitude of agents ranging from hormones to nutritional supplements (antioxidants). While some studies have demonstrated benefit to some treatments, no treatments have consistently demonstrated efficacy nor has it be...

Genetic causes of spermatogenic failure.

Approximately 10%-15% of couples are infertile, and a male factor is involved in almost half of these cases. This observation is due in part to defects in spermatogenesis, and the underlying causes, including genetic abnormalities, remain largely unknown. Until recently, the only genetic tests used in the diagnosis of male infertility were aimed at detecting the presence of microdeletions of th...

Sustained Medical Therapy for Stable Heart Failure

Cardiac transplantation is predicted to improve survival for patients with severe symptoms of heart failure and ejection fraction of 20% or less, but the exercise capacity after cardiac transplantation is less than normal. Patients responding to vasodilators and diuretics have progressive improvement in exercise capacity despite low ejection fraction. We hypothesized that among patients current...

I-34: NRY Haplotype Analysis: towards A Better Understanding of The Genetic Basis of Spermatogenic Failure

It has been established that the Y chromosome carries genes required for spermatogenesis and male fertility. For many decades worldwide screening for gene identification has been conducted in research laboratories. However, it has been a difficult process in identifying such genes (i.e. causative mutations) which could explain the phenotypic variation and could be potentially used as markers fo...
